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.
You could be injured if the vehicles roll. Set the parking brake firmly
on each vehicle. Put an automatic transmission in PARK
(P) or a
manual transmission in NEUTRAL (N).
If you have a
four-wheel-drive vehicle with
a manual transfer case shift lever, be
sure the transfer case is
not in NEUTRAL (N).

If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.

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
negative
(-1 or a metal engine part. Don’t connect (+) to (-) or you’ll
get a short that would damage the battery and maybe other parts too.

chains on your compact spare.
If You’re Stuck: In Sand, Mud, Ice or Snow
What you don’t want to do when your vehicle is stuck is to spin your wheels
too fast. The method known as “rocking” can help you get out when you’re
stuck, but
you must use caution.
I A CAUTION:
I NOTICE:
Spinning your wheels can destroy parts of your vehicle as well as
the tires. If you spin the wheels too fast while shifting your
transmission back and forth, you can destroy your transmission.
For information about using tire chains on your vehicle, see “Tire Chains”
in the Index.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will clear the area around
your front wheels. Then shift back and forth between REVERSE
(R) and a
forward gear, spinning the wheels as little as possible. Release
the
accelerator pedal while you shift, and press lightly on the accelerator pedal
when the transmission is in gear. If that doesn’t get
you out after a few tries,
you may need
to be towed out. If you do need to be towed out, see “Towing
Your Vehicle” in the Index.

Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched
warning sound when the brake pads are worn and new pads are needed. The
sound may come and go or be heard all the time your vehicle is moving
(except when you are pushing
on the brake pedal firmly).
NOTICE:
Continuing to drive with worn-out brake pads could result in
costly brake repair.
Some driving conditions or climates may cause a brake squeal when the
brakes are first applied or lightly applied. This does not mean something is
wrong with your brakes.
Your rear drum brakes don’t have wear indicators, but
if you ever hear a
rear brake rubbing noise, have the rear brake linings inspected. Also,
the
rear brake drums should be removed and inspected each time the tires are
removed for rotation or changing. When you have the front brakes replaced,
have
the rear brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, or if
there is a rapid increase in pedal travel. This could be a sign of brake
trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes adjust for wear.
If your brake pedal goes down Farther than normal, your rear drum brakes
may need adjustment. Adjust them by backing
up and firmly applying the
brakes a few times.
