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.

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. The method known
as “rocking”
can help
you get out when you’re stuck, but you must
use caution.
A CAUTION:
If you let your tires spin at high speed, they can
explode and you or others could be injured.
And, the transaxle 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.
