IN CASE OF EMERGENCY 373
JUMP STARTING
If your vehicle has a discharged battery, it can
be jump started using a set of jumper cables
and a battery in another vehicle, or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly, so please
follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack,
follow the manufacturer's operating instruc-
tions and precautions.
PREPARATIONS FOR JUMP START
The battery in your vehicle is located in the front
of the engine compartment, behind the driver
side headlight assembly.
NOTE:
If you have a diesel engine, you may have two
batteries, however jump start off the driver
side battery.
Positive (+) Battery Post
The positive battery post may be covered with a
protective cap if equipped. Lift up on the cap to
gain access to the positive battery post. Do not
jump off fuses. Only jump directly off positive
post which has a
positive (+) symbol on or around the post.
1. Apply the parking brake, shift the
automatic transmission into PARK and
turn the ignition OFF.
2. Turn off the heater, radio, and all electrical
accessories.
3. If using another vehicle to jump start the
battery, park the vehicle within the jumper
cables’ reach, apply the parking brake and
make sure the ignition is OFF.
WARNING!
Do not attempt jump starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
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.
