If your vehicle’s battery (or batteries) has run
down, you may want to use another vehicle and
some jumper cables to start your vehicle. Be sure
to use the following steps to do it safely.

They contain gas that can explode or
ignite.

They contain enough electricity to
burn you.
If you do not follow these steps exactly,
some or all of these things can hurt you.

costly damage to your vehicle that would
not be covered by your warranty.
Trying to start your vehicle by pushing or
pulling it will not work, and it could damage
your vehicle.

12-volt battery with a negative ground system.
