To reset (calibrate) the system:
1. Turn the ignition switch to ON.
2. Press the SELECT right arrow on the DIC until you
enter the GAGE mode. Then press the SELECT
down arrow until TIRE PRESSURE appears on the
display.
3. Press and hold the DIC RESET button for about
five seconds. After five seconds, the display will
show TIRE PRESSURE RESET. If TIRE
PRESSURE RESET does not appear on the
display after about five seconds, see your dealer for
service. After you release the DIC RESET button,
TIRE PRESSURE NORMAL will appear on 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
(1 05 km/h).
Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (1 2 500 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 5-65 and Wheel Replacement
on page
5-68 for more information.
The purpose
of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See “Part A: Scheduled
Maintenance Services,” in Section
6, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.

Temperature - A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade
C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are
not needed. However,
if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted
or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts should be replaced.
If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer
if any of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.

11. Using the wheel
wrench, tighten the
wheel nuts firmly in a
crisscross sequence as
shown.
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come
off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque specification. See ”Capacities
and Specifications”
in the Index for wheel nut
torque specification.
Nofice: Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten
the wheel
nuts in the proper sequence and to the proper
torque specification. See “Capacities and
Specifications”
in the index for the wheel nut torque
specification.
12. When the flat tire has been repaired or replaced,
reinstall the wheel cover. Be sure to position the
alignment pin on the cover with the notch in
the wheel. Apply pressure around the edge
of the
cap to snap it in place.
Do not use a hammer
or mallet to reinstall the cover.
Store the wheel cover in the trunk until you have
replaced the compact spare tire with
a regular tire.
Notice: Wheel covers won’t fit on your compact
spare. If you try to put a wheel cover on your
compact spare, you could damage the cover or the
spare.
