STABILITRAK
StabiliTrak systems help drivers maintain control of
their vehicles, especially during emergency lane changes
or avoidance maneuvers. StabiliTrak uses various
sensors, such as steering wheel angle, wheel speed, yaw
velocity, etc., to detect any difference between the path
requested by the steering wheel position and vehicle’s
actual path. When appropriate, the system selectively
controls brakes, engine power, and even suspension
settings to enhance control of the vehicle’s direction
and help keep it on course.
Independent studies conducted by the National Highway
Traffic Safety Administration, the Insurance Institute
for Highway Safety, and others have found StabiliTrak
to be highly effective in reducing vehicle crashes.
General Motors offers StabiliTrak systems on many of its
passenger car and light truck models.
See your owner's manual for additional information
about the operation of StabiliTrak.
Q. How do I use StabiliTrak?
A. StabiliTrak operates independently of the driver. You should continue to
drive your StabiliTrak equipped vehicle with caution and care. GM’s
StabiliTrak system, StabiliTrak is designed to be as seamless as possible
in operation, and part of the overall vehicle response to make a good
vehicle better
Q. How does StabiliTrak work?
A. StabiliTrak has the ability to apply control forces to the vehicle independent
of the driver. StabiliTrak uses sensors to continuously compare the path
indicated by the steering wheel position to the vehicle’s actual path. If a
discrepancy is detected, StabiliTrak selectively controls vehicle brakes and
engine torque to create a yaw moment that helps restore the vehicle’s
actual path to the path indicated by the steering wheel position. StabiliTrak
has the ability to help correct both understeer (where the vehicle is not
turning as much as the steering wheel position indicates) and oversteer
(where the vehicle is turning more than the steering wheel position
indicates).
Q. Will a tire change affect StabiliTrak?
A. Use of tires other than original equipment may affect StabiliTrak
performance. StabiliTrak is designed to make the best use of available
traction. The performance characteristics of the original equipment tires
are part of the overall system effectiveness. When you replace tires check
the recommendations in your owner's manual. On GM vehicles, the
original equipment tires have a “TPC” (Tire Performance Criteria) code on
the sidewall. Replacing the tires with the same “TPC” code will help assure
proper StabiliTrak performance.
An advanced computer controlled stability enhancement system assists the driver with directional control of the
vehicle in difficult driving conditions. Each time the vehicle is started, the StabiliTrak system is fully on. StabiliTrak
can be controlled by a button located on the left side of instrument panel. The condition system is displayed by a
StabiliTrak indicator light and Driver Information Center (DIC) Message. Push once to disable Traction Control.
Push and hold to disable both Traction Control and StabiliTrak. In this condition, StabiliTrak will automatically
turn ON when the vehicle speed exceeds 35 mph (56km/hr) while the Traction Control remains OFF. Push again to
enable Traction Control and StabiliTrak.
