Air Bag Warning Light
The air bags must be ready to inflate for your protectionin a collision. The Occupant Restraint Control-
ler (ORC) monitors the internal circuits and
interconnecting wiring associated with air bag
system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
AVV/START or MAR/ACC/ON/RUN position. If the
ignition switch is in the STOP/OFF/LOCK 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. 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 MAR/ACC/ON/RUN position. After the self-check,
the Air Bag Warning Light will turn off. If the ORC
detects a malfunction 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 panel Air Bag Warning Light if a malfunc-
tion is detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenance
free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!(Continued)
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.
• 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

WARNING! (Continued)
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
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. 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:
•How various systems in your vehicle were operating;
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

ParkSense Rear Park Assist Failure Indications
A malfunction of the ParkSense Rear Park Assist sensors
or system is indicated, during REVERSE gear engage-
ment, by the instrument 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 ParkSense Rear Park Assist system
is unavailable, 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.
Cleaning The ParkSense Rear Park Assist
System
Clean the ParkSense Rear Park Assist sensors with water,
car wash soap and a soft cloth. Do not use rough or hard
cloths. In washing stations, clean sensors quickly keeping
the vapor jet/high pressure washing nozzles at least 4
inches (10 cm) from the sensors. Do not scratch or poke
the sensors. Otherwise, you could damage the sensors.
ParkSense Rear Park Assist System Usage
Precautions
NOTE:
• Ensure that the outer surface and the underside of the
rear bumper is clean and clear of snow, ice, mud, dirt
or other obstruction to keep the Rear Park Assist
system operating properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of Rear Park Assist.
126 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.
• Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
302 STARTING AND OPERATING

NOTE:Do not cut or splice wiring into the vehicles
wiring harness. The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.

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 person-
nel. 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 interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
