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 3-80. 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 TC (traction
control) on/off button. See Traction Control System
(TCS) on page 4-6.
If the vehicle is in cruise control when the StabiliTrak
®
activates, the cruise control will automatically disengage.
When road conditions allow you to safely use it again,
you may reengage the cruise control. See Cruise Control
on page 3-17 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 off set from the center
position while driving straight. This is normal operation
and the vehicle is safe to drive in these cases.
Stability control activates when the computer senses a
difference between the intended path and the direction
the vehicle is actually traveling. Stability control
automatically adjusts the front road wheel steering angle,
modifies the suspension stiffness, and selectively applies
braking pressure at any one of the vehicle’s brakes to
help maintain directional control of the vehicle.
When the system activates, a STABILITY SYS ACTIVE
message displays on the Driver Information Center (DIC).
See DIC Warnings and Messages on page 3-80 You may
also hear a noise or feel vibration in the brake pedal. This
is normal. Continue to steer the vehicle in the direction
you want it to go.
