Section 5 Service and Appearance Care
5-1

The TPM system also allows the driver to check the air
pressure status of each road tire using the Driver
Information Center (DIC). Each tire’s air pressure will be
listed individually, in the following order: LF (left front
or driver’s side front tire), RF (right front or passenger’s
side front tire), RR (right rear or passenger’s side
rear tire) and LR (left rear or driver’s side rear tire). See
Ination - Tire Pressure on page 5-65for information
regarding correct tire ination. Also, seeDriver
Information Center (DIC) on page 3-57for information
on the DIC controls and displays.
If the DIC display does not show tire pressures or the
SERVICE TPM SYSTEM message appears, see
your dealer for service. The TPM system may not work
properly while the compact spare tire is installed.
Anytime you replace one or more tires or rotate your
tires, the TPM system will need to be reset. A special
tool is needed to reset the sensor identication
codes. See your dealer for service.
Your vehicle was delivered from the factory with
aluminum valve stem caps. If you ever have to replace
the valve stem caps on your vehicle, you should
replace them with aluminum or plastic caps.
The TPM system can alert you about a low or high tire
pressure condition, but it does not replace normal
tire maintenance. SeeTires on page 5-57.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 5-70andWheel Replacement
on page 5-73for more information.
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 6-4.
When rotating your tires, always use the correct rotation
pattern shown here.
Do not include the compact spare tire, if your vehicle
has one, in your tire rotation.

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 specied 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 inated and not
overloaded. Excessive speed, underination, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned
and balanced carefully at the factory to give you the
longest tire life and best overall performance.
Adjustments to wheel alignment and tire balancing will
not be necessary on a regular basis. However, if you
notice unusual tire wear or your vehicle pulling to
one side or the other, the alignment may need to be
checked. If you notice your vehicle vibrating when
driving on a smooth road, your tires and wheels may
need to be rebalanced. See your dealer for proper
diagnosis.
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. Some aluminum
wheels can sometimes be repaired. See your GM dealer
if any of these conditions exist.
Your GM dealer will know the kind of wheel you need.
