WARNING: (Continued)
Your vehicle may have a compact spare tire and
wheel assembly. If the vehicle has a compact
spare tire and wheel, they have the same overall
diameter as your vehicle's full‐size tires and
wheels. Because they were designed and
developed for use on your vehicle, it is all right to
drive your vehicle with the compact spare installed
properly. Compact spare tires are designed for
temporary use only. SeeSpare Tire
on
page 6‑93
.
{WARNING:
If you use bias-ply tires on the vehicle, the
wheel rim flanges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use
only radial-ply tires with the wheels on the
vehicle.
If you must replace your vehicle's tires with those
that do not have a TPC Spec number, make sure they
are the same size, load range, speed rating, and
construction type (radial and bias‐belted tires) as your
vehicle's original tires.
Vehicles that have a tire pressure monitoring system
could give an inaccurate low‐pressure warning if
non‐TPC Spec rated tires are installed on your vehicle.
Non‐TPC Spec rated tires may give a low‐pressure
warning that is higher or lower than the proper warning
level you would get with TPC Spec rated tires. See Tire
Pressure Monitor System on page 6‑60.
Your vehicle's original equipment tires are listed on the
Tire and Loading Information Label. See Loading the
Vehicle
on page 5‑18, for more information about the
Tire and Loading Information Label and its location on
your vehicle.

Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability, and
resistance to rollover. Additionally, if your vehicle has
electronic systems such as, antilock brakes, traction
control, and electronic stability control, the performance
of these systems can be affected.
{WARNING:
If you add different sized wheels, your vehicle
may not provide an acceptable level of
performance and safety if tires not recommended
for those wheels are selected. You may increase
the chance that you will crash and suffer serious
injury. Only use GM specific wheel and tire
systems developed for your vehicle, and have
them properly installed by a GM certified
technician.
See Buying New Tires
on page 6‑68andAccessories
and Modificationson page 6‑3for additional
information.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
The following information relates to the system
developed by the United States National
Highway Traffic Safety Administration (NHTSA),
which grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters
of 10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.

Used Replacement Wheels
{WARNING:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how
far it has 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
{WARNING:
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 you to lose control of the
vehicle and you or others may be injured in a
crash.(Continued)
WARNING: (Continued)
Use another type of traction device only if its
manufacturer recommends it for use on the
vehicle and tire size combination and road
conditions. Follow that manufacturer's
instructions. To help avoid damage to the
vehicle, drive slowly, readjust or remove the
device if it is contacting the vehicle, and do not
spin the vehicle's wheels. If you do find traction
devices that will fit, install them on the front tires.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your vehicle's tires properly.
If air goes out of a tire, it is 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, 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.

14. Tighten the wheel nuts firmly in a crisscross sequence as shown.
If your vehicle is equipped with wheel nut covers,
screw the nut covers on with your fingers, then
tighten one-quarter turn with the wheel wrench.
Notice: Wheel covers will not fit on your vehicle's
compact spare. If you try to put a wheel cover on
the compact spare, the cover or the spare could be
damaged.
Storing a Flat or Spare Tire and
Tools
{WARNING:
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.
After you have put the spare tire on your vehicle, store
the flat tire in your trunk.
Store the flat tire as far forward in the trunk as possible.
Store the jack and wheel wrench in their compartment
in the trunk. For storage, the jack must be raised until
the screw end is flush with the edge of the jack.
The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire as soon as
you can.

Spare Tire
Compact Spare Tire
{WARNING:
Driving with more than one compact spare tire at
a time could result in loss of braking and handling.
This could lead to a crash and you or others could
be injured. Use only one compact spare tire at
a time.
This vehicle may have a compact spare tire. Although
the compact spare tire was fully inflated when the
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 the vehicle, stop
as soon as possible and make sure the 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 the full-size tire repaired or
replaced at your convenience. Of course, it is best
to replace the spare with a full-size tire as soon as
possible. The spare tire will last longer and be in good
shape in case it is needed again.
Notice:
When the compact spare is installed, do not
take the vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails which can damage the tire, wheel and other
parts of the vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or wheel with
other wheels or tires. They will not fit. Keep the spare
tire and its wheel together.
Notice: Tire chains will not fit the compact spare.
Using them can damage the vehicle and can
damage the chains too. Do not use tire chains on
the compact spare.

Spare Tire
This vehicle may have a spare tire, which, when new,
was fully inflated. A spare tire may lose air over time, so
check its inflation pressure regularly. SeeInflation - Tire
Pressure
on page 6‑57and Loading the Vehicleon
page 5‑18for information regarding proper tire inflation
and loading your vehicle. For instructions on how to
remove, install or store a spare tire, see Removing the
Flat Tire and Installing the Spare Tire on page 6‑86.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inflated. Have the damaged or flat road tire
repaired or replaced as soon as you can and installed
back onto your vehicle. This way, a spare tire will be
available in case you need it again.
Your vehicle may have a different size spare tire than
the road tire originally installed on your vehicle. This
spare tire was developed for use on your vehicle, so it
is all right to drive on it.
If your vehicle has a spare tire that does not match your
vehicle's original road tires and wheels in size and type,
do not include the spare in the tire rotation.
Appearance Care
Interior Cleaning
The vehicle's interior will continue to look its best if it is
cleaned often. Although not always visible, dust and dirt
can accumulate on the upholstery. Dirt can damage
carpet, fabric, leather, and plastic surfaces. Regular
vacuuming is recommended to remove particles from
the upholstery. It is important to keep the upholstery
from becoming and remaining heavily soiled. Soils
should be removed as quickly as possible. The
vehicle's interior may experience extremes of heat
that could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to home furnishings may also transfer
color to the vehicle's interior.
When cleaning the vehicle's interior, only use cleaners
specifically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners
on surfaces for which they were not intended. Use
glass cleaner only on glass. Remove any accidental
over-spray from other surfaces immediately. To prevent
over-spray, apply cleaner directly to the cleaning cloth.
