How to Jump Start a Chevrolet Silverado 1500

1. Get the two vehicles close enough for the cables to reach without touching, then set the parking brake on both and put automatic transmissions in P (Park).
2. Turn the ignition off on both vehicles and turn off or unplug unneeded accessories, the radio and extra lights.
3. Check that the jumper cables have no loose or missing insulation.
4. Connect one end of the red positive (+) cable to the discharged battery positive (+) terminal.
5. Connect the other end of the positive (+) cable to the good battery positive (+) terminal, keeping it from touching metal first.
6. Connect the black negative (−) cable to the good battery negative (−) terminal, then the other end to the discharged battery negative (−) grounding point.
7. Start the vehicle with the good battery and run it for a while, then try starting the vehicle with the dead battery.

• To remove the cables, reverse Steps 8–11 in exact order, then let the started vehicle idle for several minutes.
• On a four-wheel-drive vehicle, make sure the transfer case is in a drive gear, not N (Neutral).
• If it will not start after a few tries, it probably needs service.
