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
ground connection you don’t want. You wouldn’t be able to start you1
vehicle, and the bad grounding could damage the electrical systems.
You could be injured if the vehicles roll. Set
the parking brake firmly
on each vehicle. Put an automatic transmission in “P’ (Park) or a
a
manual transmission in “N” (Neutral). If you have a four-wheel-drive
vehicle with
a manual transfer case shift lever, be sure the transfer case
is not in “N” (Neutral).
Turn
off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This will avoid sparks and help save both batteries.
And it could save your radio!

NOTICE:

If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative (-) terminals on each battery.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged, too.
Before you connect the cables, here are some basic things you should
know. Positive
(+) will go to positive (+) and negative (-) will go to

correct fuse.
If you ever have a problem on the road and don’t have a spare fuse, you can
“borrow”
one of the correct value. Just pick some feature of your vehicle
that you can get along without-like
the radio or cigarette lighter-and use
its fuse, if it is
of the value you need. Replace it as soon as you can. See
“Fuses and Circuit Breakers”
in this section.
