cause discoloration or stains.
Rubbing hard with a sti
ff brush or
cloth may cause damage.
If the vehicle interior becomes soiled
by any of the following, wipe it o ff
immediately using a soft cloth.
Leaving it uncleaned could cause

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 fr om 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.
