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.
Driving and Operating
When StabiliTrak activates,
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 19 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 29. When this message
is displayed and comes on and
stays on, the vehicle is safe to drive
but the system is not operational.
Driving should be adjusted
accordingly.
