Buick LaCrosse Owner Manual - 2011
Driving and Operating 9-37
Electronic Stability
Control (ESC)
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.
StabiliTrak activates when the
computer senses a difference
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 stability control system
activates, the Traction Control
System (TCS)/StabiliTrak light
flashes on the instrument panel.
This also occurs when traction
control is activated. A noise might
be heard or vibration might be 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, the TCS/StabiliTrak light
comes on and the system is not
operational. See Electronic Stability
Control (ESC)/Traction Control
System (TCS) Indicator/Warning
Light
on page 5‑20
. Driving should
be adjusted accordingly.
StabiliTrak comes on automatically
whenever the vehicle is started. To
assist with directional control of the
vehicle, the system should always
be left on.
StabiliTrak can be turned off if
needed by pressing and holding
g
until the StabiliTrak Off light comes
on the instrument panel. For
information on turning TCS off and
on, see Traction Control System
(TCS) in this section.
