an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or
a paper towel
to
do this; but be sure to use a scraper or wire
brush later,
if you need to, to get all the rust or
dirt off.

do, the nuts might come loose. Your wheel could
fall off, causing
a serious accident.

Storing a Flat or Spare Tire and Tools
I
A CdJTdN:
Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could

equipment could strike someone. Store all these
in the proper place.
1. Put the flat tire on the ground at the rear of the
vehicle, with the valve stem pointed down.
2. Tilt the retainer plate downward and through the
wheel opening. Make sure it is fully seated across the
underside
of the wheel. Attach the ratchet, with the

the hole in the rear door frame, above the bumper.
Turn the ratchet toward the right until the tire is
against the underside of the vehicle.
Keep turning the ratchet until you feel at least two
“clicks” when the tire is up all the way. Try to move
the tire with your hands to make sure it is securely
in place.
The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire as soon as
you can. See “Compact Spare Tire” in the Index. See
the storage instructions label to restore your compact
spare properly.

Downloaded from www.Manualslib.com manuals search engine Compact Spare Tire
Although the compact spare tire was fully inflated
when your vehicle was new, it can lose air after a time.
Check the inflation pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire
is correctly inflated. The compact
spare is made to perform well at speeds up
to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where you want. Of course, it’s
best to replace your spare with a full-size tire as soon
as
you can. Your spare will last longer and be in good
shape in case
you need it again.
NOTICE:
When the compact spare is installed, don’t take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
I NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on
your
compact spare.

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.
L
A CAUTION: I I
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transmission or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little
as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
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.
