Do not exceed 50 mph (80 km/h) if the "Tire Pressure
Monitoring Telltale Light" is illuminated. Vehicle
handling and braking may be reduced. You could
have a collision and be severely or fatally injured.

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.
