JUMP-STARTING

Preparations for Jump-Start
• The battery in your vehicle is located in the front of the engine compartment,
behind the left headlight assembly.
NOTE: The positive battery post is covered with a protective cap. Lift up on the
cap to gain access to the positive battery post.
• 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.
Once the engine is started, remove the jumper cables in the reverse sequence:
• Disconnect the negative (-) jumper cable from the engine ground of the vehicle
with the discharged battery.
WHAT TO DO IN EMERGENCIES
• 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.
