which
it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause 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.

Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel
could
fall off, causing a serious accident.

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 new GM original
equipment wheel nuts.
Stop somewhere
as soon as you can and have
the nuts tightened with a torque wrench to
100 lb-ft (140 Nom.)

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 Pa).
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.
I I
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.
