If your vehicle’s battery dies, it can be handy to know how to jump-start a car so you’re prepared to get it going again.
NOTE: Consult your owner’s manual first, as it has the best information for your specific vehicle.
In absence of your owner’s manual …
Grab the clean, corrosion-free jumper cables you keep in your vehicle. Or ask a fellow motorist for a pair.
Pull the working vehicle close to, but not touching, the stalled one. Turn off ignitions in both cars.
Put both vehicles in park or neutral.
- Engage emergency parking brakes.
- Pop hoods.
- Remove any terminal covers.
- Wipe or wire-brush dirty terminals.
- Don’t jump a leaky or frozen battery.
- Don’t let cable clamps touch.
- Don’t reverse the polarity (connecting positive + to negative -) or damage may occur.
- Begin at the dead battery. Attach a red clamp to the positive + terminal.
- Next, move to the working battery.
- Attach the other red clamp to the positive + terminal.
- Attach the black clamp to the negative - terminal.
- Attach the last black clamp to an unpainted metal surface on the stalled car.
- Preferably the engine block, cylinder head or other chassis ground.
- Start the working vehicle. Let the engine run a few minutes.
- Try to start the dead vehicle.
- Disconnect cables in reverse order.
- DO NOT shut the engine off. Let it run for about 15 minutes to recharge the battery.
- Recheck clamp connections.
- Run working vehicle again.
- Try to start it again.
