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 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!
Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.
Preparations For Jump-Start
The battery in your vehicle is located under the passen-
ger’s front seat. There are remote locations located under
the hood to assist in jump-starting.
548 WHAT TO DO IN EMERGENCIES

Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.
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.
• Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s bat-
tery, even when not in use (i.e., cellular phones,
etc.). Eventually, if plugged in long enough, the
vehicle’s battery will discharge sufficiently to de-
grade battery life and/or prevent the engine from
starting.
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.
• Take care to avoid the radiator cooling fan when-
ever 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 watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
