2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren't touching each other. If they are, it could cause a ground connection you don't want. You wouldn't be able to start your vehicle, and the bad grounding could damage the electrical systems. To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the procedure. Put an automatic transmission in PARK (P) and put a manual transmission in NEUTRAL. Be sure the transfer case is not in NEUTRAL. 3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the cigarette lighter, or accessory power outlets (if equipped). Turn off all lamps that aren't needed as well as radios. This will avoid sparks and help to save both batteries. In addition, it could save your radio! 4. Open both hoods and locate the batteries. (Your vehicle's battery is located towards the front of the vehicle, on the passenger side of the engine compartment. See "Engine Compartment Overview" in the Index for more information on location.) Find the positive (+) and negative (-) terminals on each battery. CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You don't need to add water to the ACDelcoR battery (or batteries) installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don't, explosive gas could be present. Battery fluid contains acid that can burn you. Don't get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately. NOTICE: If you leave your radio on, it could be badly damaged. The repair wouldn't be covered by your warranty. 5-4
