How to Jump Start a Chevrolet City Express

1. Check that the other vehicle has a 12-volt battery with a negative ground system.
2. Park the vehicles close enough for the cables to reach, but not touching each other.
3. Set the parking brake firmly on both vehicles, with automatic in P (Park) or manual in Neutral.
4. Connect the black negative (−) cable to the good battery's negative (−) terminal (3), after the positive cable is attached to the positive (+) terminal (4).
5. Connect the other end of the negative (−) cable to the negative (−) grounding point (2) on the dead vehicle's shock tower.
6. Start the good vehicle and run it a few minutes, then hold it at about 2,000 rpm and start the disabled vehicle.
7. Remove the cables by reversing the connection sequence exactly, then let the started vehicle idle for several minutes.

• Do not run the starter more than 10 seconds; if it does not start, turn the key off and wait three to four seconds.
• If it will not start after a few tries, it probably needs service.
• Connecting or removing cables in the wrong order can cause electrical shorting and damage.
