How to Jump Start a Chevrolet Impala

1. Check that the other vehicle has a 12-volt battery with a negative ground system, and park the two vehicles so they do not touch.
2. Set the parking brake on both vehicles, with automatic transmissions in P (Park) or manuals in Neutral.
3. Turn off the ignition, all lights and accessories in both vehicles, except hazard flashers if needed.
4. Connect one end of the red positive (+) cable to the jump start positive (+) terminal under the trim cover.
5. Connect the other end of the red cable to the positive (+) terminal of the good battery, without letting it touch metal.
6. Connect one end of the black negative (–) cable to the negative (–) terminal of the good battery.
7. Connect the other end of the black cable to the jump start negative (–) grounding post on the driver side shock tower.
8. Start the good vehicle and idle it at least four minutes, then try starting the dead vehicle.

• Do not connect the black cable to the dead battery; reverse the exact sequence when removing the cables.
• After the disabled vehicle starts and the cables are removed, let it idle for several minutes.
• If it will not start after a few tries, it probably needs service.
