Electronic Stability

Control (ESC)

The vehicle has an Electronic
Stability Control system called
StabiliTrak. It is an advanced
computer-controlled system that
assists with directional control of the
vehicle in difficult driving conditions.
StabiliTrak comes on automatically
whenever the vehicle is turned on.
To assist with directional control of
the vehicle, the system should
always be left on.
The system may be heard or felt
while it is working, but this is
normal.
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 to the
vehicle brakes to help steer the
vehicle in the intended direction.
When the vehicle is started and
begins to move, the system
performs several diagnostic checks
to ensure 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.
When StabiliTrak activates,
flashes on the instrument cluster.
This also occurs when traction
control is activated. This is normal.
Continue to steer the vehicle in the
intended direction. 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 Traction
Control System (TCS)/StabiliTrak
Light on page 5 23.
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 48. 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.
If comes on and stays on, reset
the system:
1. Stop the vehicle.
2. Turn the engine off and wait
15 seconds.
3. Start the engine.
