StabiliTrak
®
System
(Automatic Transmission)
Your vehicle may be equipped with a vehicle stability
enhancement system called StabiliTrak
®
.Itisan
advanced computer controlled system that assists
you with directional control of the vehicle in difficult
driving conditions.
StabiliTrak
®
activates when the computer senses a
discrepancy between your 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 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 there is a problem detected with StabiliTrak
®
,
a SERVICE STAB SYS message will be
displayed on the Driver Information Center (DIC).
See DIC Warnings and Messages on page 3-44 for
more information. When this message is displayed,
the system is not operational. Adjust your driving
accordingly.
StabiliTrak
®
comes on automatically whenever you
start your vehicle. However, when the transfer case is
placed in Four-Wheel-Low Lock mode, StabiliTrak
®
is automatically disabled. See Full-Time Four-Wheel
Drive on page 2-22 for more information. To help assist
you with directional control of the vehicle, you should
always leave the system on. You can turn StabiliTrak
®
off if you ever need to using the TC (traction control)
on/off button. If you press and hold the TC button for
five seconds, the StabiliTrak
®
system and the traction
control system will turn off. When this is done, the
STAB SYS OFF message will be displayed on the DIC.
Press the TC button again to turn StabiliTrak
®
back
on. See Traction Control System (TCS) on page 4-9.
If your vehicle is in cruise control when the StabiliTrak
®
activates, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may reengage the cruise control.
See “ Cruise Control on page 3-11 for more information.
