Jump-Starting  
Jump-starting is dangerous if done incorrectly. So follow the procedure carefully. If  
you feel unsure about jump-starting, we strongly recommend that you have a  
competent service technician do the work.  
WARNING  
Follow These Precautions Carefully:  
To ensure safe and correct handling of the battery, read the following precautions  
carefully before using the battery or inspecting it.  
Keep flames and sparks away from open battery cells and do not allow  
metal tools to contact the positive (+) or negative (–) terminal of the battery when  
working near a battery. Do not allow the positive (+) terminal to contact the  
vehicle body:  
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced  
during normal battery operation, could ignite and cause the battery to explode. An  
exploding battery can cause serious burns and injuries. Keep all flames including  
cigarettes and sparks away from open battery cells.  
Keep all flames and sparks away from open battery cells because hydrogen  
gas is produced from open battery cells while charging the battery or adding  
battery fluid:  
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced  
during normal battery operation, could ignite and cause the battery to explode. An  
exploding battery can cause serious burns and injuries. Keep all flames including  
cigarettes and sparks away from open battery cells.  
Do not jump-start a frozen battery or one with a low fluid level:  
Jump-starting a frozen battery or one with a low fluid level is dangerous. It may  
rupture or explode, causing serious injury.  
Connect the negative cable to a good ground point away from the battery:  
Connecting the end of the second jumper cable to the negative (–) terminal of the  
discharged battery is dangerous.  
A spark could cause the gas around the battery to explode and injure someone.

Route the jumper cables away from parts that will be moving:  
Connecting a jumper cable near or to moving parts (cooling fans, belts) is  
dangerous. The cable could get caught when the engine starts and cause serious  
injury.  
CAUTION  
Use only a 12 V booster system. You can damage a 12 V starter, ignition system, and  
other electrical parts beyond repair with a 24 V power supply (two 12 V batteries in  
series or a 24 V motor generator set).  
1. Move the booster vehicle so that its battery is as close as possible to your  
vehicle's battery.  
2. Make sure that the power such as for the headlights and air conditioner is turned  
off.  
3. Remove the battery cover.  
4. Turn off the booster vehicle's engine and connect the jumper cables in the  
following order.  
Make sure that the jumper cables are securely connected so that they do not  
disconnect due to engine vibrations.
