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

Jump starting 429

Connect one jumper cable to the positive (+) terminal on the discharged battery.

Connect the other end of the jumper cable to the positive (+) term- inal of the booster battery.

Connect one end of the other cable to the negative (−) terminal of the booster battery.

Connect the other end of the cable to the strut mounting nut of the vehicle with the discharged battery.

Make sure that the cables are not near any moving parts and that the cable clamps are not in contact with any other metal.

Start the engine of the vehicle with the booster battery and run it at moderate speed. Then start the engine of the vehicle that has the discharged battery.

When finished, carefully disconnect the cables in exactly the reverse order.
