Traction Control Off
In this mode, stability control and brake-traction control
are functional. Engine speed management will be
modified and the driven wheels can spin more freely.
This can cause the brake-traction control to activate
more frequently. If the controller detects excessive wheel
spin in this mode, the StabiliTrak
blink and the STABILITRAK ACTIVE message may be
displayed to warn the driver that damage may occur
to the transfer case.

StabiliTrak Off
In this mode, both stability control and part of the
traction control system are disabled. Your vehicle will
still have brake-traction control, but will not be able
to use the engine speed management system. You may
still hear system noises as a result of the brake-traction
control coming on. If the controller detects excessive
wheel spin in this mode, the StabiliTrak
may blink and the STABILITRAK ACTIVE message
may be displayed to warn the driver that damage may
occur to the transfer case.

It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if your vehicle is stuck in sand, mud, ice
or snow, and you may want to "rock" your vehicle in
an attempt to free it. It may also be necessary to turn off
the system when driving in extreme off-road conditions
where high wheel spin is required. See If Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-44 for more information.
When the transfer case is in 4LO, the stability system is
automatically disabled. The StabiliTrak
come on and the STABILITRAK OFF message will
appear on the DIC. The StabiliTrak
turned on until the vehicle is switched to 2HI, 4HI,
or 4AWD.
