1. Check the other vehicle. It must have a 12
battery with a negative ground system.
NOTICE:
If the other system isn't a 12
negative ground, both vehicles can be damaged.
Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able
to start your vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved.
Put an automatic transaxle in PARK (P) and a
manual transaxle in NEUTRAL before setting the
parking brake.

2. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn off all lamps that aren't needed as well
as the radios. This will avoid sparks and help save
both batteries. In addition, it could save the radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
