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. 62
