StabiliTrak
®
System
Your vehicle is equipped with StabiliTrak
®
, Electronic
Stability Control (ESC) which combines antilock brake,
traction and stability control systems and helps the driver
maintain directional control of the vehicle in most driving
conditions.
Traction control activates when the controller senses
wheel spin. StabiliTrak
®
will selectively apply the brakes
and reduce engine torque to help regain traction.
Stability control activates when the controller senses
a discrepancy between your intended path and the
direction the vehicle is travelling. StabiliTrak
®
selectively
applies braking pressure at any one of the vehicle’s
brakes to help guide the vehicle in the direction which
you are steering.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic checks to
insure there are no problems. You may hear or feel the
system working. This is normal and does not mean there
is a problem with your vehicle. If driving conditions delay
system initialization, the STABILITRAK NOT READY
message may be displayed. If this is the case, your
vehicle does not need servicing.
For more information on the stability messages,
see DIC Warnings and Messages on page 3-53.
When the StabiliTrak
®
system is both on and
actively controlling the
stability of the vehicle,
the StabiliTrak
®
light will
blink for the duration of
the event.
You may also feel or hear the system working.
This is normal.
The StabiliTrak
®
disable
button is located on the
transmission shift handle.
The StabiliTrak
®
system is automatically disabled in
4LO mode and cannot be turned on until the vehicle
is switched to 2HI, 4HI, or 4AWD.
The StabiliTrak
®
system has three modes of operation:
STABILITRAK ON, TRACTION CONTROL OFF,
and STABILITRAK OFF.
STABILITRAK ON -The vehicle will default to
STABILITRAK ON every time the driver starts the
vehicle. The StabiliTrak
®
light will be off and no DIC
messages will be displayed.
