StabiliTrak
®
System
The vehicle has an electronic stability control 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 20 mph (32 km/h).
In some cases, it may take approximately two miles of
driving before the system initializes.
If cruise control is being used when StabiliTrak
activates, the cruise control automatically disengages.
The cruise control can be re-engaged when road
conditions allow. See Cruise Control on page 4‑7.
If there is a problem detected with StabiliTrak, a
SERVICE STAB SYS message displays on the Driver
Information Center (DIC). See DIC Warnings and
Messages
on page 4‑36
for more information. When
this message is displayed, the system is not working.
Adjust your driving accordingly.
StabiliTrak and Traction Control (TCS) come on
automatically whenever the vehicle is started and the
systems are reset with each ignition cycle. However,
when the transfer case is placed in Four-Wheel-Low
mode, StabiliTrak is automatically disabled. See
Four-Wheel Drive
on page 3‑28
for more information.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
TCS portion of the system off if the vehicle is stuck in
sand, mud, ice, or snow, and it is necessary to “rock”
the vehicle to attempt to free it. If traction control is
turned off, only the brake-traction control portion of
traction control will work. The engine speed
management will be disabled. In this mode, engine
power is not reduced automatically and the drive wheels
can spin more freely. This can cause the brake-traction
control to activate constantly. See If Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow
