How to Jump Start a Chevrolet Silverado

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 without touching each other.
3. Set the parking brake on both vehicles and put automatic transmissions in P (Park).
4. Turn off both ignitions, unplug accessories, and switch off the radio and unneeded lamps.
5. Connect the black negative (−) cable to the good battery's negative (−) terminal, or its remote negative terminal.
6. Connect the other end of the negative (−) cable to the discharged battery's negative grounding point, keeping it clear of anything until then.
7. Start the vehicle with the good battery and let it run for a while.
8. Try starting the vehicle with the dead battery; after a few failed tries it probably needs service.

• The positive jump start connection on the discharged battery is under a slide-off cover on the passenger side.
• Remove the cables by reversing the connection sequence exactly, then let the started vehicle idle for several minutes.
• Connecting or removing cables in the wrong order can cause electrical shorting and damage not covered by warranty.
