Air Bag Warning Light
The air bags must be ready to inflate for your
protection in a collision. The Air Bag Warning
Light monitors the internal circuits and inter-
connecting wiring associated with air bag sys-
tem electrical components.
The ORC monitors the readiness of the electronic parts of the air bag system whenever the ignition
switch is in the START or ON/RUN position. If
the ignition switch is in the OFF position or in
the ACC position, the air bag system is not on
and the air bags will not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment. Also, the ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first turned to
the ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate
the instrument cluster Air Bag Warning Light if a mal-
function is detected that could affect the air bag system.
The diagnostics also record the nature of the malfunction.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 73

Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper, vehicle body structure, or
add aftermarket side steps or running boards.
• It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag system.

WARNING! (Continued)
•Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any
air bag system service. If your seat, including your
trim cover and cushion, needs to be serviced in any
way (including removal or loosening/tightening of
seat attachment bolts), take the vehicle to your
authorized dealer. Only manufacturer approved
seat accessories may be used. If it is necessary to
modify the air bag system for persons with dis-
abilities, contact your authorized dealer.
Event Data Recorder (EDR)
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

Failure Indications
A malfunction of the Rear Park Assist sensors or system
is indicated, during REVERSE engagement, by the instru-
ment panel warning icon.The warning icon is illuminated and a message
is displayed on the multifunction display (if
equipped). Refer to “Instrument Cluster De-
scriptions” in “Understanding Your Instrument
Panel” for further information.
The sensors and wiring are tested continuously when the
ignition is in the ON/RUN position. Failures are indi-
cated immediately if they occur when the system is ON. Even if the system is able to identify that a specific sensor
is in failure condition, the instrument cluster display
shall indicate that the Rear Park Assist system is unavail-
able, without reference to the sensor in failure condition.
If even a single sensor fails, the entire system must be
disabled. The system is turned off automatically.
NOTE:
The instrument cluster will NOT display any
message if the bumper sensors are dirty.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 143

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this vehicle’s
electronic system to provide immunity to radio frequency signals.
Mobile two-way radios and telephone equipment must be
installed properly by trained personnel. The following must be
observed during installation.
The positive power connection should be made directly to the
battery and fused as close to the battery as possible. The negative
power connection should be made to body sheet metal adjacent
to the negative battery connection. This connection should not
be fused.
Antennas for two-way radios should be mounted on the roof or
the rear area of the vehicle. Care should be used in mounting
antennas with magnet bases. Magnets may affect the accuracy or
operation of the compass on vehicles so equipped.The antenna cable should be as short as practical and routed
away from the vehicle wiring when possible. Use only fully
shielded coaxial cable.
Carefully match the antenna and cable to the radio to ensure a
low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater than normal
may require special precautions.
All installations should be checked for possible interference
between the communications equipment and the vehicle’s elec-
tronic systems.
