How to jump-start a car

When your vehicle does not start due to a rundown (discharged) battery, the vehicle may be jump-started by connecting one battery to another battery (called the booster battery) with jumper cables.

Jump-starting is dangerous if it is done incorrectly. If you’re unsure about the right procedure for jump-starting, consult a competent mechanic.

1. confirm the booster battery is 12 volts and therefore the negative terminal is grounded.
2. If the booster battery is in another vehicle, don’t let the 2 vehicles touch.
3. Turn off all unnecessary lights and accessories.
4. Connect the jumper cables exactly within the sequence illustrated.

1 Connect one jumper lead to the positive (+) terminal on the discharged battery.
2 Connect the opposite end of the jumper lead to the positive (+) terminal of the booster battery.
3 Connect one end of the opposite cable to the negative (–) terminal of the booster battery.
4 Connect the opposite end of the cable to the engine lifting bracket. Make sure that the cables aren’t near any moving parts in which the cable clamps aren’t in touch with the other metal.
5. Ignite the engine of the vehicle with the booster battery and run it at moderate speed thereafter start the engine of the vehicle that has the discharged battery.
6. When done, cautiously disconnect the cables in the reverse order.
