How to Jump Start a Chevrolet T Series

1. Check that the other vehicle has a 12-volt battery with a negative ground system, and park it close without the vehicles touching.
2. Set the parking brake on both vehicles and put an automatic in P (PARK) or a manual in N (Neutral).
3. Turn off the ignition on both vehicles, and switch off the radio, unneeded lamps and unplugged accessories.
4. Locate the positive (+) and negative (−) terminals on each battery; your batteries are in a battery box on the passenger's side.
5. Connect the other end of the negative (−) cable at least 18 inches (45 cm) from the dead battery, away from moving engine parts.
6. Start the vehicle with the good batteries and run the engine for a while, using high idle if equipped.
7. Try to start the vehicle with the dead batteries; if it will not start after a few tries, it probably needs service.

• Connect and remove the jumper cables in the correct order, and keep the cables from touching each other or other metal.
• To remove the cables, disconnect the black negative (−) cable from the vehicle with the dead batteries first, then from the vehicle with the good batteries.
• Diesel vehicles with two batteries: use the battery closest to the starter; one battery from another vehicle may not be enough in cold weather.
