Jump Starting

If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. But please use the following steps to do it
safely.
{
CAUTION:
Batteries can hurt you. They can be dangerous
because:
•
They contain acid that can burn you.
•
They contain gas that can explode or
ignite.
•
They contain enough electricity to
burn you.
If you don't follow these steps exactly, some
or all of these things can hurt you.

Notice: Ignoring these steps could result in costly
damage to your vehicle that wouldn't be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
won't work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice: If the other system isn't a 12-volt system
with a negative ground, both vehicles can be
damaged.
