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.

IN CASE OF EMERGENCY 489
Preparations For Jump Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE:
The positive battery post may be covered with a protective
cap if equipped. Lift up on the cap to gain access to the posi-
tive battery post. Do not jump off fuses. Only jump directly
off positive post which has a positive (+) symbol on or
around the post.
Positive Battery Post 1. Apply the parking brake, shift the automatic transmis-
sion into PARK and turn the ignition OFF.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
WARNING!
• Take care to avoid the radiator cooling fan whenever the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan blades.
• Remove any metal jewelry such as rings, watch bands and bracelets that could make an inadvertent electrical
contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable
and explosive. Keep open flames or sparks away from
the battery.
