Jump Starting
If your battery (or batteries) have 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.

If you don’t follow these steps exactly, some or all
of these things can hurt you.
NOTICE:

damage to your vehicle that wouldn’t be
covered by your warranty.
