How To Jump Start The 2012 Chevrolet Volt
Under the Hood
Under the hood, Volt looks a little different.There is an engine, but it doesn’t drive the wheels. It serves as a range-extending generator. Volt propulsion is driven by electricity 100 percent of the time. On the driver’s side, there is a power electronics module and orange high voltage cables you don’t see on traditional cars.
Volt has two batteries, a high-voltage Lithium Ion battery for propulsion and a 12V battery for various other vehicle systems. The T-shaped propulsion battery runs lengthwise within the center tunnel of the Volt with the T-shape under the rear seats. The 12V battery is located under the load floor in the hatch area, but it is equipped with remote terminals located under the hood. They provide easy access when you need to jump start the vehicle.
To jump start the Volt, open the hood to locate the positive (+) and negative (−) terminals. Open the access cover for the remote positive (+) terminal. The remote negative terminal for the Volt is a stud marked GND (−) on the driver side of the engine compartment.
IMPORTANT: 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.
Push the POWER button to start and wake up the electronics on the Volt.
After the instrument cluster initializes, the Volt will use power from the high voltage battery to charge the 12-volt battery. The jumper cables can then be disconnected.
