Batteries can fail when lights are left on, it’s cold, the battery is old, or the alternator fails. With the help of another vehicle, you may be able to jump start your battery.
How to jump start
Caution: when connected to a battery, never allow jumper cable ends to touch.
Follow these steps in order to avoid electrocution or vehicle damage:
- Position the vehicles so jumper cables can reach both batteries. Don’t let the vehicles touch.
- Turn off the ignition and set the parking brake on both vehicles.
- Connect the red positive cable to the positive (+) terminal of the good battery.
- Connect the red positive cable to the positive (+) terminal of the dead battery.
- Connect the black negative cable to the negative (-) terminal of the good battery.
- Connect the black negative cable to an engine bolt or other nonmoving metal engine part. Never attach the negative cable to the negative terminal of the dead battery. Doing so can damage the electrical system.
- Make sure the jumper cable isn’t near a fan, belt or other moving engine part.
- Start the vehicle with the good battery. Run the engine at a high idle.
- Start the vehicle with the dead battery. Once it starts, let the engine run a few minutes.
- With both engines running, disconnect the jumper cables in reverse order. Remember: never let the cable ends touch.
- Run the engine with the dead battery for at least 30 minutes to fully recharge the battery.
