(E) Tire Ply Material:The type of cord and
number of plies in the sidewall and under the
tread.
(F) Uniform Tire Quality Grading (UTQG):Tire
manufacturers are required to grade tires based on
three performance factors: treadwear, traction, and
temperature resistance. For more information see
Uniform Tire Quality Grading on page 420.
(G) Maximum Cold Ination Load Limit:
Maximum load that can be carried and the
maximum pressure needed to support that load.
(A) Temporary Use Only:The compact
spare tire or temporary use tire has a tread life of
approximately 3,000 miles (5 000 km) and should
not be driven at speeds over 65 mph (105 km/h).
The compact spare tire is for emergency use when
a regular road tire has lost air and gone at. If your
vehicle has a compact spare tire, seeCompact
Spare Tire on page 450andIf a Tire Goes Flat on
page 427.
Compact Spare Tire Example
408

The vehicle is moving faster than
70 mph (113 km/h)
The system is not yet calibrated
The tire treadwear is uneven
The compact spare tire is installed
Tire chains are being used
The vehicle is being driven on a rough or
frozen road
If the anti-lock brake system warning light comes
on, the check tire pressure system may not be
working properly. See your dealer for service. Also,
seeAnti-Lock Brake System Warning Light on
page 220.
The check tire pressure system detects differences
in tire rotation speeds that are caused by changes
in tire pressure. The system can alert you about a
low tire – but it does not replace normal tire
maintenance. SeeTires on page 406.When the LOW TIRE PRESSURE HOLD SET TO
RESET message appears on the Driver Information
Center and the LOW TIRE PRESSURE message
comes on the message center, you should stop
as soon as you can and check all your tires for
damage. If a tire is at, seeIf a Tire Goes Flat on
page 427. Also check the tire pressure in all four
tires as soon as you can. SeeInation - Tire
Pressure on page 413.
Any time you adjust a tire’s pressure or have one
or more tires repaired or replaced, you’ll need
to reset, or calibrate, the check tire pressure
system. You’ll also need to reset the system
whenever you rotate the tires, buy new tires
and install or remove the compact spare.
Do not reset the check tire pressure system without
rst correcting the cause of the problem and
checking and adjusting the pressure in all four tires.
If you reset the system when the tire pressures are
incorrect, the check tire pressure system will not
work properly and may not alert you when a tire is
low or high.
415

To reset the system, do the following:
1. With the engine off, turn the ignition to ON.
2. Press the MODE button until the DIC reads
LOW TIRE PRESSURE HOLD SET TO
RESET.
3. Press and hold the SET button until you hear
a chime, and TIRE PRESSURE RESET is
displayed.
You will hear three chimes, then the LOW TIRE
PRESSURE message will go off and the DIC
will return to TIRE PRESSURE NORMAL. If the
LOW TIRE PRESSURE message comes back on,
the check tire pressure system has not reset.
Repeat the procedure.
The system completes the calibration process
during driving. The system learns the pressure at
each tire throughout the operating speed range
of your vehicle. The system normally takes
between 30 and 60 minutes of driving to learn
the tire pressures. The system normally takes
10 to 20 minutes of driving in each speed range
to learn tire pressures. The speed ranges are
20 to 40 mph (32 to 64 km/h), 40 to 60 mph
(64 to 96 km/h), and above 60 mph (96 km/h).
This time may be longer depending on yourindividual driving habits. The learning process
does not need to be completed during a single trip.
Once learned, the system will remember the tire
pressure until the system is reset.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. SeeWhen
It Is Time for New Tires on page 418andWheel
Replacement on page 422for more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire, If it
moves, use the folding wrench to tighten the cable.
SeeStoring a Flat or Spare Tire and Tools on
page 444.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 475.
416

When rotating your tires, always use the correct
rotation pattern shown here.
Do not include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label.
Reset the check tire pressure system, if equipped.
SeeCheck Tire Pressure System on page 414.Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 469.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from 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 needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 428.
417

If you need to replace any of your wheels, wheel
bolts, or wheel nuts, replace them only with new
GM original equipment parts. This way, you will be
sure to have the right wheel, wheel bolts, and wheel
nuts for your vehicle.
{CAUTION:
Using the wrong replacement wheels,
wheel bolts, or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision
in which you or others could be injured.
Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.Notice:The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration, headlamp
aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the body and
chassis.
SeeChanging a Flat Tire on page 428for more
information.Used Replacement Wheels
{CAUTION:
Putting a used wheel on your 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.
423

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 at tire will create a drag that
pulls the vehicle toward that side. Take your foot off
the accelerator pedal and grip the steering wheel
rmly. 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
would 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.
{CAUTION:
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
at tire. If it is used for anything else, you
or others could be badly injured or killed
if the vehicle slips off the jack. Use the
jack provided with your vehicle only for
changing a at tire.
If a tire goes at, the next part shows how to use the
jacking equipment to change a at tire safely.
427

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place. Turn on
your vehicle’s hazard warning ashers. SeeHazard
Warning Flashers on page 176for more
information.
{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
CAUTION: (Continued)
CAUTION: (Continued)
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will
not move, you should put blocks at the
front and rear of the tire farthest away
from the one being changed. That would
be the tire, on the other side, at the
opposite end of the vehicle.
