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 p ossible to your vehicle's
battery.
2. Make sure that the power such as for the headlights and air c onditioner 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.
