Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been used
or how far it’s been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
Notice:Use tire chains only where legal and only
when you must. Use only SAE Class″S″type chains
that are the proper size for your tires. Install them
on the rear axle tires and tighten them as tightly as
possible with the ends securely fastened. Drive
slowly and follow the chain manufacturer’s
instructions. If you can hear the chains contacting
your vehicle, stop and retighten them. If the contact
continues, slow down until it stops. Driving too
fast or spinning the wheels with chains on will
damage your vehicle.
If a Tire Goes Flat
It’s unusual for a tire to“blowout”while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a“blowout”, here are a few
tips about what to expect and what to do:
If a front tire fails, theflat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheelfirmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop—well off the road if possible.
If a tire goesflat, the next part shows how to use your
jacking equipment to change aflat tire safely.

Removing the Spare Tire and Tools
The jacking equipment you’ll need is stored by your
vehicle’s rear doors, along the passenger’s side wall.
1. Remove the jack cover by pulling it away from
the side wall and down to release the tabs
securing the top of the cover.2. Remove the wheel blocks by turning the top nut
counterclockwise. Remove the nut and washer,
then pull the wheel blocks off the bolt.
3. Push down on the bolt and remove the hooked end
from the slot. Slide the jack toward the front of the
vehicle and lift it from the mounting. Remove
the extension and the ratchet from the pouch.

Storing a Flat or Spare Tire and Tools
{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.
1. Put theflat 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 UP side facing you, to the extension.
3. Put theflat end of the extension on an angle
through the hole in the rear door frame, above
the bumper.
The compact spare is for temporary use only.
Replace the compact spare tire with a full-size tire
as soon as you can. SeeCompact Spare Tire
on page 5-75. See the storage instructions label to
restore your compact spare properly.4. Raise the tire fully against the underside of the
vehicle by turning the ratchet/wheel wrench until
you hear two clicks or feel it skip twice. The spare
tire hoist cannot be overtightened.
5. Make sure the tire is stored securely. Push, pull,
and then try to rotate or turn the tire. If the tire
moves, use the ratchet/wheel wrench to tighten the
cable.
Return the jacking equipment to its proper location.
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 canfinish 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.
