10-78 Vehicle Care 2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not touching each other. If they are, it could cause a ground connection you do not want. You would not 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 jump start procedure. Put the automatic transmission in P (Park) or a manual transmission in N (Neutral) before setting the parking brake. If the vehicle has a four-wheel-drive transfer case with a N (Neutral) position, be sure the transfer case is in a drive gear, not in N (Neutral). Notice: If any accessories are left on or plugged in during the jump starting procedure, they could be damaged. The repairs would not be covered by the vehicle warranty. Whenever possible, turn off or unplug all accessories on either vehicle when jump starting the vehicle. 3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the accessory power outlets. Turn off the radio and all the lamps that are not needed. This avoids sparks and helps save both batteries. And it could save the radio! 4. Open the hood on the other vehicle and locate the positive (+) and negative (−) terminal locations on that 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. WARNING (Continued) If you do not follow these steps exactly, some or all of these things can hurt you. Notice: Ignoring these steps could result in costly damage to the vehicle that would not be covered by the warranty. Trying to start the vehicle by pushing or pulling it will not work, and it could damage the vehicle. 1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. Notice: Only use a vehicle that has a 12-volt system with a negative ground for jump starting. If the other vehicle does not have a 12-volt system with a negative ground, both vehicles can be damaged.
