Possible danger due to substances hazardous to health
In compliance with Proposition 65 (“Prop65”), the following detachable label has been added to each vehicle sold in California:

Operating safety
& WARNING Risk of accident due to malfunctions or system failures
If you do not have the prescribed service/ maintenance work or any required repairs carried out, this could result in malfunctions or system failures.

Always have the prescribed service and maintenance work or any required

repairs carried out in a qualified specialist workshop.

General notes 23
& WARNING Risk of accident or injury due to incorrect modifications on electronic component parts
Modification of electronic components, their software or wiring could impair their function and/or the function of other networked component parts or safety-relevant systems.
This can endanger the operating safety of the vehicle.

Never tamper with the wiring and electronic component parts or their

software.

You should have all work on electrical and electronic components carried out

at a qualified specialist workshop.
Observe the “On-board electronics” section in “Technical data”.

24 General notes

  • NOTE Impairment of the operating efficiency of the vehicle or individual components due to tampering with the on-board electronics
    The vehicle is equipped by the manufacturer with various safety mechanisms that interact with each other.
    If the system detects tampering with the onboard electronics due to an unauthorized modification of control units and/or their software/data, this may have the following effects:
    R Individual vehicle functions are (temporarily) no longer operational.
    R The overall vehicle is (temporarily) no longer operational.

    Have the vehicle checked immediately at a qualified specialist workshop and,

    if necessary, reset to factory settings.

  • NOTE Damage to the vehicle caused by driving too fast and by blows to the underbody and chassis parts
    The vehicle can be damaged in the following cases in particular:
    R The underside of the vehicle makes contact with the ground, e.g. on a high curb or an unpaved road.
    R The vehicle drives too quickly over an obstacle, e.g. a curb, a speed bump or a pothole.
    R A heavy object hits the underbody or chassis components.
    In these or similar situations, the vehicle body, the underbody, chassis components, wheels or tires and parts of the high-voltage battery could be damaged even if this is not visible. Components that have been damaged in this way can fail unexpectedly or, in the event of an accident, may not absorb the loads that arise as intended.

Have the vehicle checked and repaired immediately at a qualified specialist

workshop.
or

If driving safety is impaired during the rest of the journey, stop

immediately paying attention to the traffic situation and notify a qualified specialist workshop.
Electric vehicles have an electric motor. The electric motor is supplied with voltage via the vehicle’s high-voltage electrical system.
& DANGER Risk of death and fire due to modified and/or damaged components of the high-voltage on-board electrical system
The vehicle’s high-voltage on-board electrical system is under high voltage. If you modify component parts in the vehicle’s high-voltage on-board electrical system or touch damaged component parts, you may be electrocuted. In

addition, modified and/or damaged components may cause a fire.
In the event of an accident or impact to the underbody, components of the high-voltage electrical system may be damaged although the damage is not visible.

Never make any modifications to the high-voltage on-board electrical system.

Do not switch on or use the vehicle if its high-voltage on-board electrical

system components have been modified or damaged.

Never touch damaged components of the high-voltage on-board electrical

system.

After an accident, do not touch any components of the high-voltage on-board

electrical system.

After an accident, have the vehicle transported away.

Have the components of the high-voltage on-board electrical system checked

at a

qualified specialist workshop and replaced if necessary.
The components of the vehicle’s high-voltage onboard electrical system are marked with yellow warning stickers. The cables of the vehicle’s highvoltage electrical system are orange in color.

General notes 25

High-voltage components that can become very hot are marked with an additional warning sticker:

Example
Vehicles with electric motors generate significantly less noise when stationary and while driving than vehicles with internal combustion engines.
The vehicle therefore may not be heard by other road users due to the significantly reduced idling and driving noise.
It is for this reason that the vehicle is equipped with a sound generator, which serves as an acoustic vehicle alerting system (AVAS). This safety system is prescribed by law.

26 General notes

The outside sound produced by the sound generator (AVAS) can be heard in the vehicle interior at low speeds and does not represent a malfunction.
Fitting the license plate to the front license plate holder

  • NOTE Malfunctions and system failures due to incorrect mounting of the license plate on the front license plate holder
    If the license plate is incorrectly mounted on the front license plate holder, sensors, cameras or driving and safety systems may malfunction or fail.

Data storage
Data processing in the vehicle
Electronic control units There are electronic control units installed in your vehicle. Control units process data that they e.g. receive from vehicle sensors, generate themselves or exchange among themselves. Some control units are required for the safe operation of your vehicle. For example, some assist you when you are driving, such as driver assistance systems, while others enable convenience or infotainment functions.
The following provides you with general information regarding data processing in the vehicle. Additional information on what specific data is collected, stored and transmitted to third parties

for what purpose in your vehicle can be found in the notes on the functional features in question in the respective operating instructions. These are also available online and, depending on the equipment, digitally in the vehicle.
Personal data Each vehicle is marked with a unique vehicle identification number. Depending on the country, this vehicle identification number can be used by, for example, government authorities to determine the identity of the owner. There are other possibilities for using data collected from the vehicle to identify the owner or driver, such as the license plate number.
The data generated or processed by control units may therefore be personal or, in certain circumstances, become personal. Depending on which vehicle data are available, it may be possible to make inferences about, for example, your driving behavior, your location, your route or your use patterns.
Legal requirements for the disclosure of data If legal regulations exist, manufacturers are generally obligated to release data stored by the manu-

32 General notes

facturer to the necessary extent in individual cases at the request of state authorities. This may be the case during the investigation of a criminal offense, for example.
Within the framework of applicable law, state authorities are also authorized to take data readouts from vehicles themselves in specific cases. In the event of an accident, for example, information readouts can be taken from the air bag control unit to help to establish what happened.
Operating data in the vehicle Control units process data to operate the vehicle.
This includes the following data, for example:
R Vehicle status information such as speed, longitudinal acceleration, lateral acceleration, number of wheel revolutions or the fastened seat belts indicator
R Ambient conditions, such as temperature, rain sensor or distance sensor
As a rule, this data is volatile, is not stored beyond the operating time and is processed only in the vehicle itself. Control units (e.g. the vehicle key) often contain data memories. These are used to

temporarily or permanently document information about the vehicle’s operating state, component stress, maintenance requirements or technical events and malfunctions.
Depending on the technical equipment, the following data will be stored:
R Operating status of system components (e.g. fill levels, tire pressure, battery status)
R Malfunctions or faults in important system components (e.g. lights, brakes)
R System reactions in special driving situations (e.g. air bag deployment, the intervention of stability control systems
R Information on events leading to vehicle damage
R State of charge of the high-voltage battery; estimated range
In special cases, it may be necessary to store data that would otherwise only be volatile. This may be the case if the vehicle has detected a malfunction, for example.
If you use services such as repair services or maintenance work, stored operational data read-

outs can be taken and used together with the vehicle identification number, where necessary. Readouts can be taken by service network employees such as workshops and manufacturers, or third parties, such as breakdown services. The same is true in the case of warranty claims and quality assurance measures.
The readout will usually be taken via the diagnostics connection in the vehicle, which is required by law. The operating data readout taken documents technical conditions of the vehicle or individual components and helps to diagnose malfunctions, meet warranty obligations and improve quality. This data, particularly information on component stress, technical events, operating errors and other malfunctions, will be transmitted to the manufacturer for this purpose together with the vehicle identification number if necessary. In addition, the manufacturer is subject to product liability. For this reason, the manufacturer also uses operational data from the vehicle for e.g. recalls. This data can also be used to check customer claims for warranty and guarantee.

Fault memories in the vehicle can be reset by a service outlet or at your request as part of repair or maintenance work.
Comfort and infotainment functions You can save comfort settings and individualization in the vehicle and change or reset them at any time.
Depending on the vehicle equipment, this includes the following settings, for example:
R Seat positions and steering wheel positions
R Suspension tuning and climate control settings
R Custom settings (e.g. interior lighting)
You can incorporate data into the vehicle’s infotainment functions yourself as part of the selected equipment.
Depending on the vehicle equipment, this includes the following data, for example:
R Multimedia data (e.g. music, films or photos for playback in an integrated multimedia system)

General notes 33

R Address book data for use in conjunction with an integrated hands-free system or an integrated navigation system
R Navigation destinations that have been entered
R Data about the use of internet services
This data for comfort and infotainment functions can be saved locally in the vehicle or stored on a device that you have connected to the vehicle (e.g. smartphone, USB flash drive or MP3 player). If you have entered data yourself, you can delete it at any time.
The transfer of this data out of the vehicle will take place exclusively at your request. This applies in particular when you are using online services according to the settings you have selected.
Smartphone integration (e.g. Android Auto or Apple CarPlay®) If your vehicle is equipped appropriately, you can connect your smartphone or another mobile device to the vehicle. You will then be able to control them using the controls integrated in the vehicle. The smartphone’s picture and sound can be

output via the multimedia system. Specific items of information will also be transferred to your smartphone. Depending on the type of integration, this may include position data, day/night mode and other general vehicle statuses. Please refer to the vehicle Operator’s Manual / infotainment system operating instructions for further information.
This integration allows the use of selected smartphone apps (e.g. navigation apps, music player apps). There will be no further interaction between your smartphone and the vehicle; in particular, vehicle data will not be directly accessible. The type of additional data processing is determined by the provider of the app being used. Whether you can configure settings for it and, if so, which ones, depend on the app and your smartphone’s operating system.
Online services
Wireless network connection If your vehicle has a wireless network connection, it enables data to be exchanged between your vehicle and additional systems. The wireless net-

34 General notes

work connection is made possible by the vehicle’s own transmitter and receiver or by a mobile end device that you have brought into the vehicle, for example, a smartphone. Online functions can be used via the wireless network connection. This includes online services and applications/apps provided to you by the manufacturer or by other providers.
Manufacturer’s services Regarding the manufacturer’s online services, the individual functions are described by the manufacturer in a suitable place, for example, in the Operator’s Manual or on the manufacturer’s website, where the relevant data protection information is also given. Personal data may be used for the provision of online services. Data is exchanged via a secure connection, such as the manufacturer’s designated IT systems. Any personal data which is collected, processed and used, other than for the provision of services, is done so exclusively on the basis of legal permission. This is the case, for example, for a legally prescribed emergency call system, a contractual agreement or when consent has been given.

You can have services and functions, some of which are subject to a fee, activated or deactivated. This excludes legally prescribed functions and services, such as an emergency call system.
Third-party services If you use online services from other providers (third parties), these services are the responsibility of the provider in question and subject to that provider’s data protection conditions and terms of use. As a general rule, the manufacturer has no influence on the content exchanged.
For this reason, when services are provided by third parties, please ask the service provider in question for information about the type, extent and purpose of the collection and use of personal data.
Data protection rights
Depending on your country or the equipment and range of functions of your vehicle as well as the services you use and the services on offer, you are entitled to different data protection rights. Further information on data protection and your data protection rights can either be found on the

manufacturer’s website or you will receive this information as part of the various services and service offers. There you will also find the contact information for the manufacturer and its data protection officers. At a workshop, for example, with the support of a specialist and possibly for a fee, you can have data read out which is stored only locally in the vehicle.
MBUX multimedia system/Mercedes me connect
If the vehicle is equipped with the MBUX multimedia system or Mercedes me connect, additional data about the vehicle’s operation, the use of the vehicle in certain situations, and the location of the vehicle may be compiled by the MBUX multimedia system or Mercedes me connect. For additional information, please refer to the “MBUX multimedia system” section and/or the Mercedes me connect Terms and Conditions.
Event data recorder
USA only:

General notes 35

This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations, such as an air bag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
R How various systems in your vehicle were operating;
R Whether or not the driver and passenger safety belts were buckled/fastened;
R How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
R How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in which crashes and injuries occur. NOTE: EDR data are recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under

normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR.
EDR data may be used in civil and criminal matters as a tool in accident reconstruction, accident claims, and vehicle safety. Since the Crash Data Retrieval CDR tool that is used to extract data from the EDR is commercially available, Mercedes-Benz USA, LLC (,,MBUSA”) expressly disclaims any and all liability arising from the extraction of this information by unauthorized Mercedes-Benz personnel.
MBUSA will not share EDR data with others without the consent of the vehicle owners or, if the vehicle is leased, without the consent of the les-

see. Exceptions to this representation include responses to subpoenas by law enforcement; by federal, state or local government; in connection with or arising out of litigation involving MBUSA or its subsidiaries and affiliates; or, as required by law.
Warning: The EDR is a component of the Restraint System Module. Tampering with, altering, modifying or removing the EDR component may result in a malfunction of the Restraint System Module and other systems.
State laws or regulations regarding EDRs that conflict with federal regulation are pre-empted. This means that in the event of such conflict, the federal regulation governs. As of Dec 2016, 17 states have enacted laws relating to EDRs.

Be diligent For the components of the restraint system to provide the intended level of protection, it is essential for your posture to be correct and for the seat belt to be fastened correctly.

38 Occupant safety ­ Brief overview of the most important points

Bear in mind that negligence when adopting your sitting position and fastening your seat belt may have serious consequences. Be diligent and make sure that all vehicle occupants are sitting correctly and have fastened their seat belts properly before starting every journey.
Information on the correct seat position
The seat position must be correct in order for the components of the restraint system to provide the intended level of protection.
The seat position influences both the protection provided by the seat belt and the additional protection provided by the air bag.
The correct seat position with an almost upright posture and a correctly fastened seat belt also reduce the risk posed by the air bag when it is deployed.
When choosing the seat, take note of the available space. When you are sitting with the right posture in a nearly upright position, your head should not touch the roof.

& WARNING Risk of injury or death due to an incorrect seat position
If you deviate from the correct seat position, the air bag cannot provide its intended protective function.
Each vehicle occupant must make sure of the following.

Put the seat in the correct position.

Fasten seat belts correctly. Pregnant women must take particular care to

ensure that the lap belt never lies across the abdomen.

Observe the following information.

In order for the restraint system to provide the intended level of protection, observe the following information:
R Before starting your journey, adjust your seat correctly (/ page 94).
When doing so, make sure you are able to fasten your seat belt correctly. The shoulder belt strap must be routed forward from the seat belt outlet over the center of your shoulder.

R Keep your distance from the air bags, especially the front air bags. Set the driver’s seat and front passenger seat as far back as possible while making sure the seat belt is fastened correctly.
R If persons are sitting on the rear seats, vehicle occupants should maintain a sufficient distance to the parts of the vehicle interior in front of them.
R Make sure there are no people, animals or objects between the vehicle occupants and an air bag.
R If you are the driver, observe the following information on the correct position of the driver’s seat (/ page 94).
Hold the steering wheel only by the steering wheel rim. This allows the driver’s air bag to fully deploy.
R Assume a nearly upright position, with your buttocks as far back as possible in the gap between the seat cushion and seat backrest.
This ensures that your back lies as flat and firmly as possible against the seat backrest.

Occupant safety ­ Brief overview of the most important points 39

R While driving, do not lean forward and do not lean against the door or side window. You may otherwise be in the deployment area of the air bags.
R Sit with your feet resting on the floor, if possible. Your thighs are slightly supported by the seat cushion Do not put your feet up on the cockpit, for example. Your feet may otherwise be in the deployment area of the air bag.
R Fasten the seat belt correctly.
Notes on wearing the seat belt correctly
Always fasten your seat belt correctly before starting a journey. A seat belt can provide the best level of protection only if it is worn correctly.
& WARNING Risk of injury or death due to incorrectly fastened seat belt
If the seat belt is not worn correctly, it cannot perform its intended protective function.

In addition, an incorrectly fastened seat belt can also cause injuries, for example, in the event of an accident or when braking or changing direction suddenly.

Always ensure that all vehicle occupants have their seat belts fastened

correctly and are sitting properly.
& WARNING Risk of injury or death when additional restraint systems are not used for persons with a smaller stature
Persons under 5 ft (1.50 m ) tall cannot wear the seat belt correctly without a suitable additional restraint system.

Always secure persons under 5 ft (1.50 m) tall in a suitable restraint

system.
Each vehicle occupant must observe the following notes in particular:
R The seat belt must not be twisted:

R The shoulder belt strap must be routed forward from the seat belt outlet over the center of your shoulder.
R The shoulder belt strap should neither touch your neck nor be routed under your arm or behind your back.
R The lap belt must be routed as low down across the hips as possible.
In addition, push the lap belt down as far as possible across your hips and pull tight with the shoulder belt strap. Never route the lap belt across your abdomen.
Pregnant women must also take particular care with this.
R The shoulder belt strap and lap belt must fit snugly against the body after being tightened.
R Avoid wearing bulky clothing, e.g. a winter coat.
R Never route the seat belt across sharp, pointed, abrasive or fragile objects.
R Only one person should use each seat belt at any one time.

40 Occupant safety ­ Brief overview of the most important points

R Never secure objects with a seat belt if the seat belt is also being used by one of the vehicle’s occupants. Also ensure that no objects, e.g. a cushion, are ever placed between a person and the seat.
Fastening seat belts
If the seat belt is pulled quickly or sharply, the seat belt retractor locks. The seat belt strap cannot be pulled out any further.

Always engage seat belt tongue 2 of the seat belt into seat belt buckle 1 of

the corresponding seat.

  • NOTE Deployment of components of the restraint system when the front passenger seat is unoccupied and a seat belt is buckled
    When the front passenger seat is unoccupied and the seat belt tongue of the seat belt is engaged in the seat belt buckle, components of the restraint system may deploy unnecessarily on the front passenger side, e.g. the Emergency Tensioning Device.

    Only buckle the seat belts as intended.

    % Observe the information on the special seat belt retractor of the seat belt (/ page 62).
    Function of the restraint system warning lamp
    When the vehicle is switched on, a self-test is performed, during which the restraint system warning lamp 6 lights up. It goes out no later than a few seconds after the vehicle is started. The components of the restraint system are then functional.

Occupant safety ­ Brief overview of the most important points 41

A malfunction has occurred in the restraint system if:
R the restraint system warning lamp 6 does not light up or lights up continuously when the vehicle is switched on.
R the restraint system warning lamp 6 lights up continuously or repeatedly during a journey.
If components of the restraint system have been deployed, the restraint system warning lamp 6 will light up continuously.
& WARNING Risk of injury due to malfunctions in the restraint system
Components in the restraint system may be activated unintentionally or not deploy as planned in an accident.

Have the restraint system checked and repaired immediately at a qualified

specialist workshop.

If the restraint system is malfunctioning, the automatic high-voltage emergency shutoff may not function.
& DANGER Risk of fatal injuries due to malfunctions of the automatic high- voltage emergency shutoff
In the event of an accident, the high-voltage on-board electrical system may not be deactivated as intended.
You may be electrocuted if you touch the damaged component parts of the high- voltage onboard electrical system.

Have the automatic high-voltage emergency shutoff checked and repaired

immediately at a qualified specialist workshop.

After an accident, switch off the vehicle immediately.

Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop.

Function of the seat belt warning lamp
The seat belt warning lamp ü on the instrument display is a reminder that all vehicle occupants must wear their seat belts correctly.
The seat belt warning lamp ü lights up for six seconds every time the vehicle is started.
In addition, a warning tone may sound.
When the driver’s and front passenger doors are closed and the driver and front passenger have fastened their seat belts, the seat belt warning will go out.
The seat belt warning will light up during a journey if:
R the driver or front passenger is not wearing a seat belt and the following criteria apply:
– the vehicle speed exceeds 5 mph (9 km/h) for more than 20 seconds.
– the vehicle speed exceeds 15 mph (25 km/h) once.
R the driver or front passenger unfastens their seat belt while the vehicle is in motion.

42 Occupant safety ­ Brief overview of the most important points

Function of the rear seat belt status display
Example: vehicle with five rear seats When the vehicle is switched on, the rear seat belt status indicator will inform you for a certain amount of time which rear seat belt is not fastened. The status of the rear seat belt can be recognized by the color of the symbol on the driver’s display: R Grey: the seat belt tongue of a rear seat belt is
not engaged in the seat belt buckle of the corresponding seat.

R Green: the seat belt tongue of a rear seat belt is engaged in the seat belt buckle of the corresponding seat.
Every vehicle occupant must always fasten their seat belt correctly before starting a journey.
R Red: a vehicle occupant in the rear passenger compartment has released the seat belt buckle using the release button and may not be properly secured.
If a vehicle occupant unfastens a seat belt in the rear passenger compartment, the rear seat belt status display will appear again.
In addition, a warning tone may sound.

R The front passenger sits in such a way that their weight is raised from the seat surface.

  • NOTE Deployment of components of the restraint system when the front passenger seat is unoccupied
    In an accident, the components of the restraint system may deploy unnecessarily on the front passenger side if:
    R There are heavy objects on the front passenger seat.
    R The seat belt tongue is engaged in the seat belt buckle of the front passenger seat and the front passenger seat is unoccupied.

    Store objects in a suitable place.

46 Occupant safety ­ Information on the automatic functions of the restraint system

Only one person should use each seat belt at any one time.

Depending on the detected accident situation, the window air bag on the front passenger side may deploy. The air bag is deployed regardless of whether the front passenger seat is occupied.
Function of PRE-SAFE® (anticipatory occupant protection)
PRE-SAFE® is able to detect certain critical driving situations and implement pre-emptive measures to protect the vehicle occupants. PRE-SAFE® can implement the following measures independently of each other: R Tightening the seat belts on the driver’s seat
and front passenger seat. R Closing the side windows. R Vehicles with sliding sunroof: closing the slid-
ing sunroof.

R Vehicles with memory function: moving the front passenger seat to a more favorable seat position.
R PRE-SAFE® Sound: provided that the multimedia system is switched on, generating a brief noise signal to stimulate the innate protective mechanism of a person’s hearing.

  • NOTE Damage caused by objects in the footwell or behind the seat
    The automatic adjustment of the seat position may result in damage to the seat and/or the object. # Stow objects in a suitable place.
    Reverting the PRE-SAFE® system measures
    If an accident did not occur, the pre-emptive measures that were taken will be reversed. You will need to perform certain settings yourself. # If the seat belt pre-tensioning is not reduced,
    move the seat backrest back slightly. The locking mechanism will release.

Seat belt adjustment function
Vehicles with PRE-SAFE®: after you have fastened the seat belt of the front seat, it may adjust itself against your body by pulling at the shoulder until somewhat tight. Do not hold the seat belt tightly while it is adjusting. This function is a reminder that all vehicle occupants must wear their seat belts correctly. You can activate and deactivate the seat belt adjustment function using the multimedia system (/ page 46).

Overview of the automatic measures after an accident
Depending on the type and severity of the accident, and depending on the vehicle’s equipment, the following measures can be implemented, forexample:
R automatic braking (post-collision brake)
R activating the hazard warning lights
R triggering an automatic emergency call (/ page 288)
R switching off the drive system and high-voltage on-board electrical system
R unlocking the vehicle doors
R lowering the side windows
R displaying the emergency guide in the central display
R switching on the interior lighting

Function of the post-collision brake after an accident
Depending on the accident situation, the post-collision brake can minimise the severity of a further collision or even avoid it.
If an accident is detected, the post-collision brake can initiate automatic braking. When the vehicle has come to a standstill, the electric parking brake is automatically applied.
The driver can cancel automatic braking by taking the following actions:
R Braking more strongly than automatic braking
R Fully depressing the accelerator pedal with force

Purpose and function of the restraint system
Overview of deployment situations (restraint system)
Make sure that the following prerequisites in particular have been met so that the components of the restraint system are able to provide the intended level of protection:
R Sit correctly (/ page 38).
R Fasten the seat belt correctly (/ page 39).
– Function of the seat belt warning lamp (/ page 41).
– Function of the rear seat belt status display (/ page 42).
R The restraint system warning lamp 6 is not lit up after the self-test (/ page 40).
R The PASSENGER AIR BAG indicator lamps display the correct status of the front passenger air bag (/ page 42).

48 Occupant safety ­ Purpose and function of the restraint system

Depending on the detected deployment situation, the components of the restraint system can be activated or deployed independently of each other:
R Emergency Tensioning Device: frontal impact, rear impact, side impact, rollover
R Driver’s air bag, front passenger air bag: frontal impact
R Knee air bag: frontal impact R Side impact air bag: side impact R Window curtain air bag: side impact, rollover,
frontal impact
The installation location of an air bag is identified by the AIRBAG symbol (/ page 53). Observe the information on the function of the restraint system (/ page 48).
Information on how the restraint system works
How the restraint system functions depends on the severity of the impact detected and the apparent type of accident.

For more information about types of accidents, see “Overview of deployment situations” (/ page 47).
The activation thresholds for the components of the restraint system are determined based on the evaluation of the sensor values measured at various points in the vehicle. This process is pre-emptive in nature. The triggering/deployment of the components of the restraint system must take place in good time at the start of the collision.
Factors that can be seen and measured only after a collision has occurred cannot play a decisive role in air bag deployment. Nor do they provide an indication of air bag deployment.
The vehicle may be deformed significantly without an air bag being deployed. This is the case if only parts which are relatively easily deformed are affected and the rate of vehicle deceleration is not high. Conversely, an air bag may be deployed even though the vehicle suffers only minor deformation. If very rigid vehicle parts such as longitudinal members are hit, this may result in sufficiently high levels of vehicle deceleration.

Depending on the apparent type of accident and the detected deployment situation, Emergency Tensioning Devices and/or air bags can supplement the protection offered by a correctly worn seat belt.
When enabled, an air bag can provide additional protection for the respective vehicle occupant.
Potential protection provided by each air bag:
R Knee air bag: thigh, knee and lower leg
R Driver’s air bag, front passenger air bag: head and ribcage
R Window air bag: head
R Side air bag: ribcage and pelvis
However, no system available today can completely eliminate injuries and fatalities in every accident situation. In particular, the seat belt and air bag generally do not protect against objects penetrating the vehicle from the outside. It is also not possible to completely rule out the risk of injury caused by the air bag deploying.
Mercedes-Benz recommends that you have the vehicle towed to a qualified specialist workshop after an accident. Take this into account, particu-

Occupant safety ­ Purpose and function of the restraint system 49

larly if an Emergency Tensioning Device is triggered or an air bag deployed.
If the Emergency Tensioning Devices are triggered or an air bag is deployed, you will hear a bang, and a small amount of powder may also be released:
R The bang will not generally affect your hearing.
R In general, the powder released is not hazardous to health but may cause short-term breathing difficulties to persons suffering from asthma or other pulmonary conditions.
Provided it is safe to do so, leave the vehicle immediately or open the window in order to prevent breathing difficulties.
Air bags and pyrotechnic Emergency Tensioning Devices contain perchlorate material, which may require special handling or environmental protection measures. National guidelines regarding waste disposal must be observed. In California, see the https://dtsc.ca.gov/. Using the search function, you will find information on perchlorate, for example.

Information on the limited protection provided by the restraint system
Risk due to the incorrect behavior of vehicle occupants
All vehicle occupants must make sure of the following in particular:
R They observe the information on the correct seat position (/ page 38).
R There are no heavy, sharp-edged or fragile objects in the pockets of their clothing. Store such objects in a suitable place.
& WARNING Risk of injury or death due to an incorrect seat position
The seat belt does not offer the intended level of protection if you have not moved the seat backrest to an almost vertical position.
In particular, you could slip beneath the seatbelt and become injured.

Adjust the seat properly before beginning your journey.

Always ensure that the seat backrest is in an almost vertical position and

that the shoulder belt is routed across the center of your shoulder.
