How to Jump Start a GMC Sierra 1500 Limited

1. Check that the other vehicle has a 12-volt battery with a negative ground system, then park the vehicles close but not touching.
2. Set the parking brake on both vehicles, put automatic transmissions in P (Park), and turn both ignitions off.
3. Turn off the radio and unneeded lamps, and unplug accessories on both vehicles.
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, or the remote positive (+) terminal if there is one.
6. Connect the black negative (−) cable to the good battery negative (−) terminal, or the remote negative (−) terminal if there is one.
7. Connect the other end of the negative (−) cable to the discharged vehicle's negative (−) grounding point, not its battery terminal.
8. Start the good vehicle and run it a while, then try to start the dead one.

• Remove the cables by reversing the connection sequence exactly, 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 the vehicle will not start after a few tries, it probably needs service.
