The anti-lock brake system warning light may also come on when you are driving with
a compact spare tire. If
this happens, the light means you won’t have anti-lock

If the warning light stays on after you replace the
compact spare with

That’s normal.

A CAUTION:
Getting under a vehicle when it is jacked up is
dangerous.
If the vehicle slips off the jack, you
could be badly injured
or kill,ed. Never get under
a vehicle when it
is supported only by a jack.
Raise the vehicle by rotating the wheel wrench
clockwise. Raise the vehicle far enough
off the ground
so there is enough room for the spare tire to fit.
Remove all the wheel nuts and take
off the flat tire.

Tighten the wheel nuts
firmly in a criss-cross
sequence as
shown. A CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become
loose and even come
off. This could lead to an
accident. Be sure to use the correct wheel nuts.
If you have to replace them, be sure to get the
right kind.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to
100
ft. Ibs. (140.m).
Don't try to put a wheel cover on your compact spare
tire. It won't fit. Store the.whee1 cover
in the trunk until
you have the flat tire repaired
or replaced.

Now put all the equipment back securely in the trunk.
Compact Spare Tire
Although the compact spare 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). The compact spare is made to go up to 3,000 miles
(5000 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 ti\
re
as soon as you can. Your spare will last longer and be in
good shape in case you need it again.
Your anti-lock brake system warning light may come on
when you are driving with a compact spare. See
“Anti-Lock Brake System Warning Light” in the Index.

Don’t use your compact spare on some other vehicle.
And don’t mix^ your compact spare or wheel with other
wheels or tires. They won’t fit. Keep your spare
and its
wheel together.
A CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment
of the vehicle could
cause injury. In a sudden .stop or collision,
loose equipment could strike someone. Store all
these in the proper place.

When to Check: Check your tires once a month or
more.
Don’t forget your compact spare tire. It should be at
60
psi (420 kPa).
I
How to Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking at the tires will not
tell you the pressure, especially
if you have radial tires --
which may look properly inflated even if they’re
underinflated.
If your tires have valve caps, be sure to put them back on. They help prevent leaks .by keeping out dirt and
moisture.
Tire Inspection and Rotation
To make your tires last longer, have them inspected and
rotated at the mileages recommended
in the
Maintenance, Schedule. See “Scheduled Maintenance
Services”
in the Index.
r-
Use this rotation pattern.
After the tires have been rotated, adjust the front and
rear inflation pressure
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque”
in the
Index.
