System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition
OFF.
Air Bag Warning Light
The air bags must be ready to inflate for your protection
in 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
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.
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 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 79

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, 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.

NOTE:It is recommend to also remove the radar sensor
on vehicle equipped to Adaptive Cruise Control (ACC).
This radar sensor is specifically calibrated to your vehicle
and is not interchangeable with other radar sensors.
Radar sensor removal procedure (If equipped with
Adaptive Cruise Control [ACC]):
1. With the lower fascia removed, which provides access
to the sensor and bracket, disconnect the wiring
harness from the sensor.
2. Using a suitable tool, disconnect the wire clip from the
bracket.
3. Using a suitable tool, remove the two fasteners that
hold the sensor bracket to the bumper beam.
NOTE:It is recommended to scribe location to assist in
reinstallation.
4. Locate the protective connector on the rear of the
bumper beam.

NOTE:Only models with the Off Road Package are
equipped with the a protective connector.
5. Remove the plug from the protective connector and
install on the sensor.
6. Insert the wiring harness connector into the protective
connector.
7. Store sensor and bracket in a safe place.
NOTE:All cruise control functions will be disabled when
the radar sensor is disconnected.
Radar sensor installation procedure (If equipped with
Adaptive Cruise Control [ACC]):
1. Disconnect the wiring harness connector from the
protective connector on the bumper beam.
2. Remove plug from radar sensor and install in protec-
tive connector.
3. Using the previously scribed marks, reinstall the radar
sensor and bracket using the two fasteners.
NOTE:Some alignment may be required upon fascia
installation to align sensor with fascia.
4. Install the wiring harness connector into the radar
sensor.
NOTE:If you receive a fault, see your authorized dealer
they may need to perform a sensor alignment.
Lower Front Fascia Installation (This will only work if
you have a helper. We suggest):
1. Starting at the center of the vehicle, engage a sufficient
number of tabs to support the weight of the lower
fascia (typically one or two tabs) into the upper fascia.
2. Working your way outward, engage the tabs into the
slots on one side of the vehicle.
460 STARTING AND OPERATING

•Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
1,653 lbs (750 kg).
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.

CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Fog Lamps
1. Reach through the cutout in the splash shield and
disconnect the wiring harness from the fog lamp
connector.
2. Firmly grasp the bulb by the two latches and squeeze
them together to unlock the bulb from the back of the
front fog lamp housing.
3. Pull the bulb straight out from the keyed opening in
the housing.
CAUTION!
•Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If
the bulb comes in contact with any oily surface,
clean the bulb with rubbing alcohol.
•Always use the correct bulb size and type for
replacement. An incorrect bulb size or type may
overheat and cause damage to the lamp, the socket
or the lamp wiring.
4. Align the index tabs of the front fog lamp bulb with
the slots in the collar of the bulb opening on the back
of the front fog lamp housing.
5. Insert the bulb into the housing until the index tabs are
engaged in the slots of the collar.

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 prop-
erly 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 pos-
sible. 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 in-
terference between the communications equip-
ment and the vehicle’s electronic systems.
