Air Bag Warning Light
The air bags must be ready to inflate for your
protection in a collision. The Occupant Restraint
Controller (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 in the MAR/
ACC/ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a malfunc-
tion 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 malfunction is
detected that could affect the air bag system. The diagnos-
tics 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.
•
The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the MAR/ACC/ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protection.
Have an authorized dealer service the air bag system
immediately.
46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bags to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.
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, in-
cluding 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.
(Continued)
WARNING! (Continued)
•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 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 disabilities, 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 performed.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 47

While audible signals are emitted, the audio system is not
muted.
The audible signal is turned off immediately if the distance
increases. The tone cycle remains constant if the distance
measured by the inner sensors is constant. If this condition
occurs for the external sensors, the signal is turned off after
three seconds (stopping warnings during maneuvers par-
allel to walls).
ParkSense Rear Park Assist Failure Indications
A malfunction of the Park Assist sensors or system is
indicated, during REVERSE gear engagement, by the in-
strument panel warning icon.The warning icon is illuminated and a message is
displayed on the multifunction display (if
equipped). Refer to “Instrument Cluster Descrip-
tions” 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 indicated
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 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 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 ParkSense Rear Park Assist
system operating properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of Park Assist.
• Clean the Park Assist sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 101

•When replacing tires, refer to “Tires – General Informa-
tion” in “Starting And Operating” for the proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated 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 hy-
draulic brake lines. It can overload your brake sys-
tem 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 dis-
tance. When towing you should allow for additional
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.

340 INDEX

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.
