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 dan-
gerous if done improperly so please follow the
procedures in this section carefully.
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 elec-
trical system may occur.
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 under the
passenger's front seat. There are remote loca-
tions located under the hood to assist in jump-
starting.
