Product Usage Instructions:

Toyota Safety Sense 2.5:

The Toyota Safety Sense 2.5 is a drive assist system designed to
enhance safety and comfort during driving. It includes the
following components:

• PCS (Pre-Collision System): This system helps reduce the impact
  of collisions or assists the driver in normal driving conditions.
  However, it is important to note that the driver is always
  responsible for paying attention to the vehicle’s surroundings and
  driving safely.

• LTA (Lane Tracing Assist): This system assists in keeping the
  vehicle within its lane by providing steering assistance. It is not
  intended for fully autonomous driving and requires the driver’s
  attention.

• AHB (Automatic High Beam): This system automatically switches
  between high beam and low beam headlights based on detected traffic
  conditions, improving visibility during nighttime driving.

• RSA (Road Sign Assist): This system uses a front camera to
  detect and display road signs on the vehicle’s instrument panel,
  helping the driver stay informed about speed limits, stop signs,
  and other important signs.

Sensors:

The drive assist systems rely on two types of sensors located
behind the front grille and windshield to detect information
necessary for their operation. It is important to keep these
sensors clean and avoid any modifications or disassembly that may
affect their functionality.

Radar Sensor:

To ensure proper operation of the radar sensor, follow these
precautions:

• Keep the radar sensor and its cover clean at all times.

• Do not disassemble, modify, or paint the radar sensor or its
  cover.

• If the radar sensor needs recalibration, contact your Toyota
  dealer for assistance.

Front Camera:

To ensure proper operation of the front camera, follow these
precautions:

• Keep the windshield in front of the front camera clean.

• Avoid attaching objects or stickers to the outer side of the
  windshield in front of the front camera.

• If the windshield is damaged or replaced, the front camera must
  be recalibrated by a Toyota dealer.

• Avoid allowing liquids or bright lights to contact the front
  camera.

• Do not dirty or damage the front camera.

• When cleaning the inside of the windshield, avoid allowing
  glass cleaner to contact the lens of the front camera and do not
  touch the lens directly.

FAQ (Frequently Asked Questions):

Q: How does Toyota Safety Sense 2.5 contribute to a safe

driving experience?

A: Toyota Safety Sense 2.5 includes various drive assist systems
such as PCS, LTA, AHB, and RSA, which help reduce collisions,
provide lane tracing assistance, improve visibility with automatic
high beam control, and detect road signs for driver awareness.

Q: What should I do if the radar sensor or front camera needs

recalibration?

A: If the radar sensor or front camera needs recalibration, it
is recommended to contact your Toyota dealer for assistance.

Q: Can I attach stickers or objects to the windshield in front

of the front camera?

A: No, it is advised not to attach any objects or stickers to
the outer side of the windshield in front of the front camera as it
may affect its operation.

WARNING To avoid malfunction of the
radar sensor Observe the following precautions. Otherwise, the radar sensor may not operate properly, possibly leading to an accident resulting in death or serious injury. Keep the radar sensor and the
radar sensor cover clean at all times.
Radar sensor Radar sensor cover If the front of the radar sensor or the front or back of the radar sensor cover is dirty or covered with water droplets, snow, etc., clean it. Clean the radar sensor and radar sensor cover with a soft cloth to avoid damaging them. Do not attach accessories, stickers (including transparent stickers) or other items to the radar sensor, radar sensor cover or surrounding area. Do not subject the radar sensor or its surrounding area to a strong impact. If the radar sensor, front grille, or front bumper has been subjected to a strong impact, have the vehicle inspected by your Toyota dealer.

Do not disassemble the radar sensor.
Do not modify or paint the radar sensor or radar sensor cover.
In the following cases, the radar sensor must be recalibrated. Contact your Toyota dealer for details.
· When the radar sensor or front grille are removed and installed, or replaced
· When the front bumper is replaced
To avoid malfunction of the front camera
Observe the following precautions. Otherwise, the front camera may not operate properly, possibly leading to an accident resulting in death or serious injury. Keep the windshield clean at all
times. · If the windshield is dirty or cov-
ered with an oily film, water droplets, snow, etc., clean the windshield. · If a glass coating agent is applied to the windshield, it will still be necessary to use the windshield wipers to remove water droplets, etc., from the area of the windshield in front of the front camera. · If the inner side of the windshield where the front camera is installed is dirty, contact your Toyota dealer.

When the temperature around the front camera is outside of the operational range, such as when the vehicle is in the sun or in an extremely cold environment

If a sunshade was used when the vehicle was parked, depending on its type, the sunlight reflected from the surface of the sunshade may cause the temperature of the front camera to become excessively high.

If the front camera is cold, such after the vehicle is parked in an extremely cold environment, use the air conditioning system to increase the temperature around the front camera.

LTA (Lane Tracing Assist)
Summary of functions
While driving on a road with clear white (yellow) lane lines, the LTA system warns the driver if the vehicle may deviate from the current lane, and also can slightly operate the steering wheel to help avoid deviation from the lane. Also, while the dynamic radar cruise control with full-speed range is operating, this system will operate the steering wheel to maintain the vehicle’s lane position.
The LTA system recognizes white (yellow) lane lines using the front camera. Additionally, it detects preceding vehicles using the front camera and radar. *: May recognize the boundaries
between the asphalt and the side of the road, such as grass, soil, or the curb, to be road lanes

WARNING Before using LTA system Do not rely solely upon the LTA
system. The LTA system does not automatically drive the vehicle or reduce the amount of attention that must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving safely by paying careful attention to the surrounding conditions and operating the steering wheel to correct the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention may lead to an accident, resulting in death or serious injury.
The lane centering function will be disabled automatically when LTA detects a trailer connection. Turn off the lane centering function if a trailer is connected and it is not automatically disabled. After trailer disconnect and power switch is turned off, lance centering function can be turned on.
Do not use the lane centering system and steering assist function when the vehicle is lifted unless using a Toyota official lift up kit up to 4 in. (101 mm), including tire height. Aftermarket lift kits may degrade system performance.
Situations unsuitable for LTA system
In the following situations, use the LTA switch to turn the system off. Failure to do so may lead to an accident, resulting in death or serious injury.
