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 5 9.
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 4 12 or Adaptive Cruise
Control on page 4 15 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.
®
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 4 76.
It is normal to hear a noise or feel vibration in the brake
pedal when the system is working. Continue to steer the
vehicle in the intended direction.
If cruise control is engaged when Enhanced StabiliTrak
activates, the cruise control will automatically
disengage. Re-engage cruise control when road
conditions allow. See Cruise Control on page 4 12,
or Adaptive Cruise Control on page 4 15 for more
information.
Enhanced StabiliTrak comes on automatically in the
Stability Touring Mode, when the vehicle is started.
The Stability Touring Mode is recommended for normal
driving.
