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, see
Anti-Lock Brake System Warning Light on page 3-38.
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 doesn't replace normal tire maintenance. See
Tires
on page 5-58.
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center, you should stop as
soon as you can and check all your tires for damage. If
a tire is ¯at, see
If a Tire Goes Flat on page 5-66.
Also check the tire pressure in all four tires as soon as
you can. See
In¯ation -- Tire Pressure on page 5-58.
Any time you adjust a tire's pressure or have one
or more tires repaired or replaced, you'll need to reset
(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.
Don't 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.To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until TIRE
PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about ®ve
seconds. After ®ve seconds, the display will show
TIRE PRESSURE RESET. If TIRE PRESSURE
RESET does not appear in the display after about
®ve seconds retry the process. If it does not work
after two tries, see your dealer for service. After you
release the DIC RESET button, TIRE PRESSURE
NORMAL will appear in the display.
The system completes the calibration process during
driving. Calibration time can take 45 to 90 minutes,
depending on your driving habits. After the system has
been calibrated, the system will alert the driver that
a tire is low, up to a maximum speed of 65 mph
(105 km/h).
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 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. See
When It Is Time
for New Tires on page 5-62andWheel Replacement
on page 5-65for more information.
5-60

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The ®rst rotation
is the most important. See ªPart A: Scheduled
Maintenance Services,º in Section 6, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.
Don't include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear in¯ation pressures as shown on the Tire-Loading
Information label.Reset the check tire pressure system, if equipped. SeeCheck Tire Pressure System on page 5-59.
Make certain that all wheel nuts are properly tightened.
See ªWheel Nut Torqueº under
Capacities and
Speci®cations on page 5-93.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make 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
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. See ªChanging a Flat
Tireº in the Index.
5-61

{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels. It's all right to drive with your
compact spare temporarily, it was developed
for use on your vehicle. See ªCompact Spare
Tireº in the index.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim ¯anges 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 your vehicle.
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, 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
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.

The following steps will tell you how to use the jack and
change a tire.
Removing the Spare Tire and Tools
The equipment you'll need is located in the trunk.
1. Pull the carpeting from the ¯oor of the trunk.
2. Lift and remove the cover.
3. Remove the compact spare tire. See
Compact
Spare Tire on page 5-76for more information
about the compact spare.
4. Unscrew the wing nuts to remove the container that
holds the wrench and jack.
5. Remove the wheel wrench, jack and the spare tire
from the trunk.
5-68

Removing the Flat Tire and Installing
the Spare Tire
1. Use the wheel wrench to loosen the wheel nuts, but
don't remove them yet.
2. The jack has a bolt at the end. Attach the wheel
wrench to the bolt to create a jack handle.3. Turn the wheel wrench counterclockwise to lower
the jack head until it ®ts under the vehicle.
5-70

4. Put the jack into a notch in the frame which is
located near each wheel well. The front notch is
eight inches (20 cm) back from the front wheel well.
The rear notch is three inches (8 cm) forward
from the rear wheel well. The notches are
accessible through openings in the plastic trim at
the bottom of the vehicle.
Position the jack and raise the jack head until it ®ts
®rmly on the ridge in the vehicle's frame nearest
the ¯at tire. Do not raise the vehicle yet. Put
the compact spare tire near you.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get
under a vehicle when it is supported only by
a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to ®t the
jack lift head into the proper location before
raising the vehicle.
5-71

5. Raise the vehicle by turning the wheel wrench
clockwise in the jack. Raise the vehicle far
enough so there's enough room for the spare tire to
®t under the wheel well.
6. Remove all the wheel nuts and take off the ¯at tire.7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
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.
