How to Jump Start a GMC Acadia Limited

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 make sure they do not touch each other.
3. Set the parking brake firmly on both vehicles and put an automatic transmission in P (Park) or a manual in Neutral.
4. Turn off both ignitions, unplug unneeded accessories, and turn off the radio and unneeded lamps.
5. Open the hoods and find the positive (+) and negative (−) terminals on the other vehicle and the remote jump starting terminals on yours.
6. Connect the other end of the negative (−) cable to the remote negative (−) terminal of the dead battery.
7. Start the vehicle with the good battery and run the engine for a while, then try to start the other vehicle.

• If the vehicle will not start after a few tries, it probably needs service.
• To remove the cables, reverse the connection sequence exactly, then let the started vehicle idle for several minutes.
• Connecting or removing the cables in the wrong order may cause electrical shorting and damage.
