Buick 2009 Enclave - Manual (Page 242)

StabiliTrak ® System
The vehicle may be equipped with 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.
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 assist the driver with keeping the vehicle on
the intended path.
When the system activates, STABILITY CONTROL
ACTIVE comes on the Driver Information Center (DIC).
See DIC Warnings and Messages on page 3-56.
The system may be heard or felt while it is working.
This is normal. Continue to steer the vehicle in the
intended direction.
The Traction Control
warning light comes on the
instrument panel cluster
when a problem is
detected with StabiliTrak.
If there is a problem detected with StabiliTrak, a
SERVICE STABILITY SYSTEM or STABILITY
CONTROL OFF message will be displayed on the DIC.
When this message is displayed, the system is not
operational. Driving should be adjusted accordingly.
If cruise control is being used when StabiliTrak activates,
the cruise control automatically disengages. The
cruise control can be reengaged when road conditions
allow. See Cruise Control on page 3-10 for more
information.
