Important safety information

WARNING

• Rear visibility systems (backup cameras) are required in certain new vehicles sold in the U.S. and Canada. U.S. regulations began according to a two-year phase-in on May 1, 2016, and both the U.S. and Canada require that all such vehicles manufactured on or after May 1, 2018, have rear visibility systems. Owners of vehicles equipped with compliant rear visibility systems should not install or use this product in a way that alters or disables that system’s compliance with applicable regulations.
• If you are unsure whether your vehicle has a rear visibility system subject to U.S. or Canadian regulations, please contact the vehicle manufacturer or dealer.
• If your vehicle has a compliant backup camera that displays the backup view through the factory receiver, do not use the Pioneer receiver unless it is connected to and displays the same view as the factory backup camera. Connection to the factory backup camera will require an adaptor, sold separately. Not all vehicles may be able to connect. Please check with a qualified professional installer for installation options specific to your vehicle.

Precautions

Your new product and this manual

• Do not operate this product, any applications, or the rearview camera option (if purchased) if doing so will divert your attention in any way from the safe operation of your vehicle.
• Always observe safe driving rules and follow all existing traffic regulations. If you experience difficulty in operating this product, pull over, park your vehicle in a safe location, and apply the parking brake before making the necessary adjustments.
• Do not install this product where it may

1. obstruct the driver’s vision,
2. impair the performance of any of the vehicle’s operating systems of safety features, including airbags, and hazard lamp buttons, or
3. impair the driver’s ability to safely operate the vehicle. In some cases, it may not be possible to install this product because of the vehicle type or the shape of the vehicle interior.

Important safeguards

WARNING

• Pioneer does not recommend that you install this product yourself. This product is designed for professional installation only.
• We recommend that only authorized Pioneer service personnel, who have special training and experience in mobile electronics, set up and install this product.
• NEVER SERVICE THIS PRODUCT YOURSELF. Installing or servicing this product and its connecting cables may expose you to the risk of electric shock or other hazards, and can cause damage to this product that is not covered by warranty.

Precautions before connecting the system

• WARNING Do not take any steps to tamper with or disable the parking brake interlock system which is in place for your protection. Tampering with or disabling the parking brake interlock system could result in serious injury or death.

CAUTION

• Secure all wiring with cable clamps or electrical tape. Do not allow any bare wiring to remain exposed.
• Do not directly connect the yellow lead of this product to the vehicle battery. If the lead is directly connected to the battery, engine vibration may eventually cause the insulation to fail at the point where the wire passes from the passenger compartment into the engine compartment. If the yellow lead’s insulation tears as a result of contact with metal parts, short-circuiting can occur, resulting in considerable danger.
• It is extremely dangerous to allow cables to become wound around the steering column or shift lever. Be sure to install this product, its cables, and wiring away in such so that they will not obstruct or hinder driving.
• Make sure that the cables and wires will not interfere with or become caught in any of the vehicle’s moving parts, especially the steering wheel, shift lever, parking brake, sliding seat tracks, doors, or any of the vehicle’s controls.
• Do not route wires where they will be exposed to high temperatures. If the insulation heats up, wires may become damaged, resulting in a short circuit or malfunction and permanent damage to the product.
• Do not shorten any leads. If you do, the protection circuit (fuse holder, fuse resistor or filter, etc.) may fail to work properly.
• Never feed power to other electronic products by cutting the insulation of the power supply lead of this product and tapping into the lead. The current capacity of the lead will be exceeded, causing overheating.

Before installing this product

• Use this unit with a 12-volt battery and negative grounding only. Failure to do so may result in a fire or malfunction.
• To avoid shorts in the electrical system, be sure to disconnect the (–) battery cable before installation.

To prevent damage

• WARNING  When speaker output is used by 4 channels, use speakers over 50 W (Maximum input power) and between 4 Ω to 8 Ω (impedance value). Do not use 1 Ω to 3 Ω speakers for this unit.
• The black cable is ground. When installing this unit or power amp (sold separately), make sure to connect the ground wire first. Ensure that the ground wire is properly connected to the metal parts of the car’s body.
• The ground wire of the power amp and the one of this unit or any other device must be connected to the car separately with different screws. If the screw for the ground wire loosens or falls out, it could result in fire generation of smoke or malfunction.

Non-supplied for this unit

• When replacing the fuse, be sure to only use a fuse of the rating prescribed on this product.
• This product cannot be installed in a vehicle without the ACC (accessory) position on the ignition switch.
• To avoid short-circuiting, cover the disconnected lead with insulating tape. It is especially important to insulate all unused speaker leads, which if left uncovered may cause a short circuit.
• For connecting a power amp or other devices to this product, refer to the manual for the product to be connected. The graphical symbol placed on the product means direct current.

Notice for the blue/white lead

• When the ignition switch is turned on (ACC ON), a control signal is output through the blue/white lead.
• Connect to an external power amp’s system remote control terminal, the auto-antenna relay control terminal, or the antenna booster power control terminal (max. 300 mA 12 V DC).
• The control signal is output through the blue/white lead, even if the audio source is switched off.
