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 started and
cannot be turned off.
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 help
steer the vehicle in the intended
direction.
Driving and Operating
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 the stability control system
activates, the Traction Control
System (TCS)/StabiliTrak light
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.
