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.
WARNING:
Operating, servicing and maintaining a
passenger vehicle or off-road highway
motor vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to
the State of California to cause cancer and
birth defects or other reproductive harm.
To minimize exposure, avoid breathing
exhaust, do not idle the engine except as
necessary, service your vehicle in a
well-ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to
www.P65Warnings.ca.gov/passenger-vehicle.

DRIVING AND ALCOHOL
Drunken driving is one of the most frequent causes of
accidents.
Your driving ability can be seriously impaired with blood
alcohol levels far below the legal minimum. If you are
drinking, don’t drive. Ride with a designated non-
drinking driver, call a cab, a friend, or use public trans-
portation.
WARNING!
Driving after drinking can lead to an accident.
Your perceptions are less sharp, your reflexes are
slower, and your judgment is impaired when you
have been drinking. Never drink and then drive.
This manual illustrates and describes the operation of
features and equipment that are either standard or op-

disregard any features and equipment described in this
manual that are not on this vehicle.

WARNING!
•Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the center
of the seat.
• Being too close to the Side Air Bags during deploy-
ment could cause you to be severely injured or
killed.
• Relying on the Side Air Bags alone could lead to
more severe injuries in a collision. The Side Air Bags
work with your seat belt to restrain you properly. In
some collisions, Side Air Bags won’t deploy at all.
Always wear your seat belt even though you have
Side Air Bags.
NOTE: Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The ORC determines whether the deployment of
the Side Air Bags in a particular rollover event is appro-
priate, based on the severity and type of collision. Vehicle
damage by itself is not a good indicator of whether or not
Side Air Bags should have deployed. The Side Air Bags will not deploy in all rollover events. The
rollover sensing system determines if a rollover event may
be in progress and whether deployment is appropriate. In
the event the vehicle experiences a rollover or near rollover
event, and deployment of the Side Air Bags is appropriate,
the rollover sensing system will also deploy the seat belt
pretensioners on both sides of the vehicle.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events.

NOTE:
The Occupant Restraint Controller (ORC) monitors
the internal circuits and interconnecting wiring associated
with electrical Air Bag System Components listed below:
• Occupant Restraint Controller (ORC)
