WHAT TO DO IN EMERGENCIES

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.
Preparations for Jump-Start
• The battery in your vehicle is located in the right rear of the engine compartment.
• Set the parking brake, shift the automatic transmission into PARK and turn the
ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• If using another vehicle to jump-start the battery, park the vehicle within the jumper
cables reach, set the parking brake and make sure the ignition is OFF.
Jump-Starting Procedure
• Connect the positive (+) end of the jumper cable to the positive (+) post of the
discharged vehicle.
• Connect the opposite end of the positive (+) jumper cable to the positive (+) post of
the booster battery.
• Connect the negative end (-) of the jumper cable to the negative (-) post of the
booster battery.
• Connect the opposite end of the negative (-) jumper cable to a good engine ground
(exposed metal part of the discharged vehicle's engine) away from the battery and
the fuel injection system.
• Start the engine in the vehicle that has the booster battery, let the engine idle a few
minutes, and then start the engine in the vehicle with the discharged battery.
