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 ba ttery, 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 al l 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 al l 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.
