Check Tire Pressure System (If Equipped)
The check tire pressure system can alert you to a large
change
in the pressure of one tire. The system won’t alert
you before you drive that a tire is low or flat. You must
begin driving before the system will work properly.
The CHECK
TIRE PRESSURES message will appear
on the Driver Information Center (DIC) if pressure in
one tire becomes at least
€0 psi (69 kPa) lower or higher
than the other three tires. The warning message can be
removed from the display by pressing any DIC button.
Removing the message does not reset the system. The
check tire pressure system won’t alert you if more than
one tire is low or high, or if the system
is not calibrated
properly. It also won’t tell you which tire is low or high.
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” in the Index.)
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” in the Index. When
the CHECK TIRE PRESSURES 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 flat, see “If a Tire Goes Flat” in the Index.) Also
check the tire pressure in all four tires as soon as you
can. See “Inflation-Tire Pressure” in the Index.
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, install or remove the compact spare, and
whenever the vehicle’s battery has been disconnected.
Don’t reset the check tire pressure system without first
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.

Uniform Tire Quality Grading
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.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction -- A, B, C
The traction grades, from highest to lowest, are A, B,
and C, and they represent the tire’s ability to stop on wet
pavement as measured under controlled conditions
on
specified government test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire
is based
on braking (straight ahead) traction tests and does not
include cornering (turning) traction.
