WHAT TO DO IN EMERGENCIES Preparations for Jump-Start • The battery in your vehicle is located in the front of the engine compartment, behind the left headlight assembly. WARNING! • Take care to avoid the radiator cooling fan whenever 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. • Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep open flames or sparks away from the battery. • 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 a 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. WARNING! Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result. Jump-Starting Procedure WARNING! Failure to follow this procedure could result in personal injury or property damage due to battery explosion. • 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. 54
