Used Replacement Wheels
{ Warning
Replacing a wheel with a used one
is dangerous. How it has been used or how far it has been driven may
be unknown. It could fail suddenly and cause a crash. When replacing wheels, use a new GM original
equipment wheel.
Tire Chains
{ Warning
If the vehicle has 265/45R18 size tires on the rear axle, do not use tire chains. There is not enough
clearance. Tire chains used on a
vehicle without the proper amount of clearance can cause damage to
the brakes, suspension, or other
vehicle parts. The area damaged by the tire chains could cause loss of
control and a crash. Use another type of traction device only if its
(Continued)

manufacturer recommends it for
the vehicle's tire size combination and road conditions. Follow that manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the traction device if it contacts the vehicle. Do not spin the wheels. If traction
devices are used, install them on the rear tires.
Caution
If the vehicle is equipped with a tire size other than 265/45R18 on the
rear, use tire chains only where
legal and only when necessary. Use
low profile chains that add no more than 10 mm thickness to the tire
tread and inner sidewall. Use chains that are the proper size for the tires. Install them on the tires of the rear axle. Do not use chains on the tires of the front axle. Tighten them as

tightly as possible with the ends
securely fastened. Drive slowly and follow the chain manufacturer's
instructions. If the chains contact the 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 the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires are maintained properly. See Tires 0 348.
If air goes out of a tire, it is much
more likely to leak out slowly. But if
there is ever a blowout, here are a few tips about what to expect and what
to do:
If a front tire fails, the flat tire creates a drag that pulls the vehicle toward
that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly. Steer to maintain lane
position, and then gently brake to a stop, well off the road, if possible.
VEHICLE CARE 369
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction as used in a skid. Stop pressing the accelerator
pedal and steer to straighten the
vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off the road, if possible.
{ Warning
Driving on a flat tire will cause permanent damage to the tire.
Re-inflating a tire after it has been driven on while severely
underinflated or flat may cause a
blowout and a serious crash. Never attempt to re-inflate a tire that has been driven on while severely
underinflated or flat. Have your
dealer or an authorized tire service center repair or replace the flat tire as soon as possible.
{ Warning
Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. If a
jack is provided with the vehicle, it is designed only for changing a flat tire. If it is used for anything else,
you or others could be badly injured or killed if the vehicle slips off the
jack. If a jack is provided with the vehicle, only use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard Warning Flashers 0 184.
{ Warning
Changing a tire can be dangerous.
The vehicle can slip off the jack and roll over or fall causing injury or

death. Find a level place to change
the tire. To help prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic
transmission in P (Park) or a manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine and do not restart while the vehicle is raised.
4. Do not allow passengers to remain in the vehicle.
5. Place wheel blocks,
if equipped, on both sides of
the tire at the opposite corner of the tire being changed.
This vehicle may come with a jack and spare tire or a tire sealant and compressor kit. To use the jacking equipment to change a spare tire
safely, follow the instructions below. Then see Tire Changing 0 376. To use
