JUMP-STARTING
• If your vehicle has a discharged battery it can be jumpstarted 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
instructions and precautions.
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!
When temperatures are below the freezing point, electrolyte in a discharged battery
may freeze. Do not attempt jump-starting because the battery could rupture or
explode and cause personal injury. Battery temperature must be brought above the
freezing point before attempting a jump-start.
