How to Jump Start a Buick Encore

1. Check that the other vehicle has a 12-volt battery with a negative ground system, and park the two vehicles so they do not touch.
2. Set the parking brake firmly and put the shift lever in P (Park) or Neutral with a manual transmission.
3. Turn the ignition off and switch off all lights and accessories in both vehicles, except hazard flashers if needed.
4. Connect one end of the red positive (+) cable to the discharged battery positive (+) terminal, under the trim cover.
5. Connect the other end of the red cable to the good battery positive (+) terminal.
6. Connect one end of the black negative (–) cable to the good battery negative (–) terminal, then the other end to the discharged battery negative (–) terminal.
7. Start the engine of the vehicle with the good battery and let it idle for at least four minutes.
8. Try to start the vehicle with the discharged battery; if it will not start after a few tries, it probably needs service.

• Remove the jumper cables by reversing the connection sequence exactly.
• After removing the cables, let the started vehicle idle for several minutes.
• Connecting or removing the cables in the wrong order can cause electrical shorting and damage not covered by warranty.
