Precautions
Your new product and this manual
  Do not operate this product, any applications, or the rear 
view 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 or reading the display, 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 (i) obstruct the 
driver’s vision, (ii) impair the performance of any of the 
vehicle’s operating systems of safety features, including 
airbags, hazard lamp buttons, or (iii) impair the driver’s abil-
ity 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 discon-
nect the (–) battery cable before installation.
To prevent damage
WARNING
  Use speakers over 50 W (output value) 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 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.

  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.
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.
