StabiliTrak
®
System
The vehicle has a vehicle stability enhancement system
called StabiliTrak. It is an advanced computer controlled
system that assists with directional control of the vehicle
in difficult driving conditions.
If the vehicle has all-wheel-drive and has Active
Steering with Enhanced StabiliTrak, see Enhanced
StabiliTrak
®
on page 4-6.
StabiliTrak activates when the computer senses a
discrepancy between the intended path and the direction
the vehicle is actually traveling. StabiliTrak selectively
applies braking pressure at any one of the vehicle’s
brakes to help steer the vehicle in the intended direction.
When the system activates, a STABILITY SYS ACTIVE
message will be displayed on the Driver Information
Center (DIC). See DIC Warnings and Messages on
page 3-79. A noise may be heard or a vibration felt in the
brake pedal. This is normal. Continue to steer the vehicle
in the intended direction.
If there is a problem detected with StabiliTrak, a
SERVICE STABILITY SYS message will be displayed on
the DIC. See DIC Warnings and Messages on page 3-79.
When this message is displayed, the system is not
operational. Driving should be adjusted accordingly.
StabiliTrak comes on automatically whenever the
vehicle is started. To help assist with directional control
of the vehicle, always leave the system on. StabiliTrak
can be turned off, however, by using the Traction
Control System (TCS)/StabiliTrak button. See Traction
Control System (TCS) on page 4-10.
If cruise control is being used when StabiliTrak activates,
it will automatically disengage. Cruise control may be
reengaged when road conditions allow. See Cruise
Control on page 3-16 or Adaptive Cruise Control
on page 3-20 for more information.
Enhanced StabiliTrak
®
All-wheel-drive (AWD) vehicles with the Active Steering
with Enhanced StabiliTrak option have an enhanced
computer controlled vehicle stability system that assists
with directional control of the vehicle in difficult driving
conditions. This system coordinates automatic control of
the Active Steering System, the Magnetic Ride Control
Suspension System, and the Brake Control System
for better vehicle performance.
During extreme cold temperature conditions, the active
steering function may be temporarily disabled which may
cause the steering wheel to be offset from the center
position while driving straight. This is normal operation
and the vehicle is safe to drive in these cases.
