How to Jump Start a GMC Canyon

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 shift to P (Park) for an automatic or N (Neutral) for a manual.
3. Turn the ignition off and switch off all lights and accessories in both vehicles, except hazard flashers if needed.
4. Connect the red positive (+) cable to the discharged battery positive (+) terminal, then to the good battery positive (+) terminal.
5. Connect the black negative (–) cable to the good battery negative (–) terminal, then to the discharged battery negative (–) grounding point.
6. Start the good vehicle and let it idle for at least four minutes, then try starting the vehicle with the dead battery.
7. To remove the cables, reverse Steps 6–9 in exact order.

• The discharged battery positive (+) terminal is under a trim cover; pull the small cover outboard, and close it afterward until the lock latches.
• If the vehicle will not start after a few tries, it probably needs service.
• Inspect the jumper cables first; do not use cables with loose or missing insulation.
