10-82 Vehicle Care Jump Starting Another Vehicle When using the Volt to jump start another vehicle with a run‐down battery, jumper cables are connected directly to the positive (+) and negative (−) terminals on the 12‐volt battery in the rear cargo area. Do not use the remote terminals under the hood. This could cause a fuse to overload in the Volt. 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. 2. Park both vehicles close enough so that the jumper cables can reach both vehicles' positive (+) and negative (−) terminals. The vehicles must not touch each other. It could cause an unwanted ground connection that could damage both vehicles' electrical systems. Put both vehicles in P (Park) for an automatic transmission or electric drive unit. For a manual transmission, place the vehicle in N (Neutral) and set the parking brake. Notice: If the radio or other accessories are left on during the jump starting procedure, they could be damaged. The repairs would not be covered by the warranty. Always turn off the radio and other accessories when jump starting the vehicle. 3. Turn off both vehicles. Turn off the radio, all lamps, and accessories that are not needed in both vehicles. Unplug accessories from the cigarette lighter or the accessory power outlets. This avoids sparks and helps save both batteries and accessories. Disconnecting the Jumper Cables 1. Disconnect the black negative (−) jumper cable from the Volt. Do not let the other end of the cable touch anything until after the next step. 2. Disconnect the black negative (−) jumper cable from the other vehicle with the good battery. 3. Disconnect the red positive (+) jumper cable from the other vehicle. Do not let the other end of the cable touch anything until after the next step. 4. Disconnect the red positive (+) jumper cable from the Volt. 5. Return the positive (+) and negative (−) terminal covers to their original positions.
