Electronic Stability
Control (ESC)
The vehicle may have 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 there is a
difference between the intended
path and the direction the vehicle is
actually traveling. StabiliTrak
selectively applies braking pressure
to the vehicle's brakes to help steer
the vehicle in the intended direction.
StabiliTrak comes on automatically
whenever the vehicle is started.
To assist with directional control of
the vehicle, the system should
always be left on.
When StabiliTrak activates,
d
flashes on the instrument panel.
A noise may be heard or vibration
may be felt in the brake pedal.
This is normal. Continue to steer the
vehicle in the intended direction.
See Electronic Stability Control
(ESC)/Traction Control System
(TCS) Indicator/Warning Light on
page 5‑17 for more information.
If a problem is detected with
StabiliTrak, Service StabiliTrak is
displayed on the Driver Information
Center (DIC). See Ride Control
System Messages on page 5‑27.
