Position the cars for jump starting
- 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. Put on safety glasses.
- 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.
Attaching the jumper cables
- Grab the clean, corrosion-free jumper cables you keep in your vehicle or ask a fellow motorist for a pair.
- 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.
Removing the jumper cables
If the engine starts running
- Disconnect cables in reverse order.
- DO NOT shut the engine off. Let it run for about 15 minutes to recharge the battery.
Car battery still dead
- Recheck clamp connections.
- Run working vehicle again.
- Try to start it again.
If that still doesn’t work then that’s where State Farm® Emergency Road Service coverage comes in handy.
