Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine
whether to have the Enhanced Accident Response Sys-
tem perform the following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the ignition switch is turned to the “OFF” posi-
tion.
• Turn on the interior lights, which remain on as long as
the battery has power or until the ignition switch is
turned to the “OFF” position.
• Unlock the doors automatically.
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 the air bag system is not on and the air
bags will not inflate.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 57

WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment 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 placed in
the on position, and stays on after you start the
vehicle, or if it comes on as you drive, have an
authorized dealer service the air bag system immedi-
ately.
Generic Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (“SRS”), the generic warning
light will illuminate in flashing mode on the
instrument panel. The Generic warning light will stay on in flashing mode
until the fault is cleared. If the generic warning light
comes on intermittently on while driving have an autho-
rized dealer service the vehicle immediately.
For additional information regarding the Generic Warn-
ing light refer to the “Instrument Panel” section of this
manual.
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

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 parallel to walls).
ParkSense® Rear Park Assist Failure Indications
A malfunction of the ParkSense® Rear Park Assist sen-
sors or system is indicated, during REVERSE gear en-
gagement, 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 in (10 cm) from the sensors. Do not scratch or poke
the sensors. Otherwise, you could damage the sensors.

CAUTION!
If the trailer weighs more than 1,000 lbs (454 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.NOTE:Do not cut or splice wiring into the vehicles
wiring harness.

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 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.
