Jump Starting: Service and Repair

Jump Starting with an Auxiliary (Booster) Battery

CAUTION: See Service Precautions. Service Precautions

Jump Starting Procedure
1. Set the vehicle parking brake.
If the vehicle is equipped with an automatic transmission, place the selector level in the "PARK" position. Turn "OFF" the ignition.
Turn "OFF" all lights and any other accessory requiring electrical power.
2. Attach the end of one jumper cable to the positive terminal of the booster battery.
Attach the other end of the same cable to the positive terminal of the discharged battery.
Do not allow the vehicles to touch each other. This will cause a ground connection, effectively neutralizing the charging procedure.
Be sure that the booster battery has a 12 volt rating.
3. Attach one end of the remaining cable to the negative terminal of the booster battery.
Attach the other end of the same cable to a solid engine ground (such as the air conditioning compressor bracket or the generator mounting bracket) of the vehicle with the discharged battery.
The ground connection must be at least 450 mm (18 in.) from the battery of the vehicle whose battery is being charged.

WARNING: NEVER ATTACH THE END OF THE JUMPER CABLE DIRECTLY TO THE NEGATIVE TERMINAL OF THE DEAD BATTERY.

4. Start the engine of the vehicle with the good battery.
Make sure that all unnecessary electrical accessories have been turned "OFF".
5. Start the engine of the vehicle with the dead battery.
6. To remove the jumper cables, follow the above directions in reverse order.
Be sure to first disconnect the negative cable from the vehicle with the discharged battery.
