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.

Driving and Operating
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 22. Driving should
be adjusted accordingly.
