Notice: If you leave your radio or other accessories on during the jump starting procedure, they could be damaged. The repairs would not be covered by your warranty. Always turn off your radio and other accessories when jump starting your vehicle. 3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the cigarette lighter or accessory power outlets. Turn off the radio and all lamps that are not needed. This will avoid sparks and help save both batteries. And it could save your radio! 4. Open the hoods and locate the positive (+) and negative (−) terminal locations of the other vehicle. Your vehicle has a remote positive (+) jump starting terminal and a remote negative (−) jump starting terminal. You should always use these remote terminals instead of the terminals on the battery. The remote positive (+) terminal is located near the engine accessory drive bracket. On some vehicles, the terminal may be covered by a red plastic cover. To access the remote positive (+) terminal, open the cover, if equipped. The remote negative (−) terminal is located on the engine accessory drive bracket and is marked GND (Ground). See Engine Compartment Overview on page 5-12 for more information on the location of the remote terminals. 5-41
