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.(Continued)
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 includ-
ing 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 autho-
rized dealer.
66 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 fuse block 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. The EDR in this vehicle
is designed to record such data as:

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.
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.
Refer to the following illustrations.

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENTSpecial 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 interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
