When the system is on,
this warning light, located
on the instrument panel
cluster, will come on to let
you know if there’s a
problem, or if the system
has been turned off.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Traction Control
System on. But you can turn the system off if you
prefer.
To turn the system on or off, press the traction control
button (TC) located under the climate controls. In
order to effectively “rock” the vehicle, you will need to
turn off TCS.If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. The StabiliTrak
®system will
stay on. Press the TC button again to turn the system
back on. The traction control system warning light will go
off. If you press and hold the TC button, the StabiliTrak
®
system and the traction control system will turn off.
Press the TC button again to turn StabiliTrak®and the
traction control system back on. For more information,
seeStabiliTrak
®System on page 4-12.
When you turn the system off, the Traction Control
System warning light will come on and stay on. If the
Traction Control System is limiting wheel spin when you
press the button to turn the system off, the warning
light will come on – but the system won’t turn off right
away. It will wait until there’s no longer a current need to
limit wheel spin.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3for more information.

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.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a speci ed government test course.
For example, a tire graded 150 would wear one and
a half (1.5) 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 signi cantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on speci ed 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 straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
