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, see
StabiliTrak
®System on page 265.
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 308for more information.
Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction
System (ETS) that limits wheel spin. This is
especially useful in slippery road conditions. The
system operates only if it senses that one or
both of the front wheels are spinning or beginning
to lose traction. When this happens, the system
reduces engine power and may also upshift
the transaxle to limit wheel spin.
This light, located on
the instrument panel,
will come on when your
Enhanced Traction
System is limiting
wheel spin.
You may feel or hear the system working, but this
is normal.

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 (NHTSA), 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 (UTQG)
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.
