Jump Starting

To avoid damage to the vehicle and battery (10653) or the possibility of personal harm, follow these instructions and precautions:

 WARNING: HYDROGEN AND OXYGEN GASES ARE PRODUCED DURING NORMAL BATTERY OPERATION. THIS GAS MIXTURE CAN EXPLODE IF FLAMES, SPARKS OR LIGHTED TOBACCO ARE BROUGHT NEAR THE BATTERY . WHEN CHARGING OR USING A BATTERY IN AN ENCLOSED SPACE, ALWAYS PROVIDE VENTILATION AND SHIELD YOUR EYES.

 WARNING: KEEP OUT OF REACH OF CHILDREN. BATTERIES CONTAIN SULFURIC ACID. AVOID CONTACT WITH SKIN, EYES OR CLOTHING. ALSO, SHIELD YOUR EYES WHEN WORKING NEAR THE BATTERY TO PROTECT AGAINST POSSIBLE SPLASHING OF THE ACID SOLUTION. IN CASE OF ACID CONTACT WITH SKIN, EYES OR CLOTHING, FLUSH IMMEDIATELY WITH WATER FOR A MINIMUM OF FIFTEEN MINUTES. IF ACID IS SWALLOWED, DRINK LARGE QUANTITIES OF MILK OR WATER, FOLLOWED BY MILK OF MAGNESIA, A BEATEN EGG, OR VEGETABLE OIL. CALL A PHYSICIAN IMMEDIATELY.

 CAUTION: Do not disconnect the battery of the vehicle to be started. Disconnecting the battery could damage the vehicle's electronic system.

Negative Grounded Battery

 WARNING: TO AVOID ANY POSSIBILITY OF INJURY, USE PARTICULAR CARE WHEN CONNECTING A BOOSTER BATTERY TO A DISCHARGED BATTERY .

 WARNING: WHEN SERVICING THE STARTER OR PERFORMING OTHER UNDERHOOD WORK IN THE VICINITY OF THE STARTER MOTOR (11002) , BE AWARE THAT THE HEAVY GAUGE BATTERY INPUT LEAD AT THE STARTER SOLENOID (11390) IS "ELECTRICALLY HOT" AT ALL TIMES.

A PROTECTIVE CAP OR BOOT IS PROVIDED OVER THIS TERMINAL THAT MUST BE REPLACED AFTER SERVICING. BE SURE TO DISCONNECT BATTERY GROUND CABLE BEFORE SERVICING STARTER MOTOR.

1. Position vehicles so jumper cables will reach, being careful that vehicles do not touch.

2. Turn heater blower motor (18527) of vehicle to be started ON (set control on DEFROST for vehicles equipped with automatic temperature control). Turn other switches and lamps OFF.

    WARNING: MAKING THE FINAL CABLE CONNECTION COULD CAUSE AN ELECTRICAL SPARK NEAR THE BATTERY AND COULD CAUSE AN EXPLOSION. REFER TO WARNING AT THE BEGINNING OF THE JUMP STARTING PROCEDURE.

3. Make jumper cable connections.
   • Connect one end of first jumper cable to the battery positive voltage (+) terminal of discharged battery and other end to the battery positive voltage (+) terminal of booster battery .
   • Connect one end of second jumper cable to battery negative voltage (-) terminal of booster battery. Connect other end to an engine bolthead or good metallic contact spot on engine of vehicle to be started, NOT TO BATTERY NEGATIVE VOLTAGE (-) TERMINAL.
   
   
   
   
   
   • Make sure jumper cables are not in way of moving engine parts.
   • Start engine of vehicle with good battery . Run engine at a moderate speed.
   • Start engine of vehicle with discharged battery . Follow starting instructions in the Owner Guide.
   • Leave all switches except FOR heater blower motor OFF. Reduce engine speed to idle on both vehicles to prevent possible damage to vehicle electrical systems.

4. Remove cables in exact REVERSE sequence. Begin by removing cable from engine of vehicle that had discharged battery .

   If the starter motor does not turn the engine over, even with the booster battery attached, refer to Starter System Diagnosis in this Section.
