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.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. 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 turned to the 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. The air bags may
not be ready to inflate for your protection. Promptly
check the Body Control Module (BCM) fuse block inside
the vehicle for blown fuses. Refer to the label located on
the inside of the fuse block cover for the proper air bag
fuses. See your authorized dealer if the fuse is good.
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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

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 3 seconds (stopping warnings during
maneuvers parallel to walls).
Failure Indications
A malfunction of the Rear Park Assist sensors or system
is indicated, during REVERSE gear engagement, by the
instrument panel warning icon and message displayed
on the Electronic Vehicle Information Center (EVIC)
display.The warning icon is illuminated and a message
is displayed on the EVIC display (if equipped). Refer to
Electronic Vehicle Information Center (EVIC) 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 EVIC shall indicate that the
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 Rear Park Assist System
Clean the 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
128 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.
