Ride Control Systems
StabiliTrak ® System
The vehicle may have a vehicle
stability enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists the driver 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 vehicle is started and
begins to move, the system
performs several diagnostic checks
to insure there are no problems.
The system may be heard or felt
while it is working. This is normal
and does not mean there is a
problem with the vehicle.
The system should initialize before
the vehicle reaches 32 km/h
(20 mph). In some cases, it may
take approximately 3.2 km (2 mi) of
driving before the system initializes.
The Traction Control System (TCS)/
StabiliTrak indicator light comes on
the instrument panel cluster when
the system requires service.
When StabiliTrak activates, the
TCS/StabiliTrak indicator light
flashes on the instrument panel.
This also occurs when TCS is
activated.
For more information, see Traction
Control System (TCS)/StabiliTrak
®
Light on page 5‑26.
For your safety, the system can only
be disabled when the vehicle speed
is less than 32 km/h (20 mph).
Press the StabiliTrak button located
on the instrument panel once to turn
off the Traction Control System
(TCS). The appropriate message is
displayed in the DIC.
Press and hold the StabiliTrak
button for more than five seconds to
turn off StabiliTrak and TCS.
