How to Jump Start a Chevrolet Colorado

1. Make sure 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) 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 one end of the red positive (+) cable to the discharged battery positive (+) terminal, then the other end to the good battery positive (+) terminal.
5. Connect one end of the black negative (–) cable to the good battery negative (–) terminal, then the other end to the discharged battery negative (–) grounding point.
6. Start the engine of the good-battery vehicle and let it idle for at least four minutes.
7. Try starting the vehicle with the dead battery; if it will not start after a few tries, it probably needs service.
8. 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. The negative grounding point is below the windshield washer fluid reservoir.
• After removing the cables, let the started vehicle idle for several minutes, then close the small cover until it latches.
• Inspect the jumper cables first and do not use any with loose or missing insulation.
