The traction control part of StabiliTrak can be turned off
by pressing and releasing the StabiliTrak button if both
systems (traction control and StabiliTrak) were
previously on. To disable both TCS and StabiliTrak,
press and hold the button for five seconds.
TCS and StabiliTrak can be turned on by pressing and
releasing the StabiliTrak button if not automatically shut
off for any other reason.
When TCS or StabiliTrak is turned off, the StabiliTrak
light and the appropriate message will be displayed on
the DIC to warn the driver. The vehicle will still have
brake-traction control when traction control is off, but
will not be able to use the engine speed management
system. See Traction Control Operation next for more
information.
When the traction control system has been turned off,
system noises may still be heard as a result of the
brake-traction control coming on.
The traction control
disable button is located
on the instrument panel
below the climate
controls.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to rock the vehicle to 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
When the transfer case is in 4LO, the stability system is
automatically disabled, the StabiliTrak light comes on
and the STABILITRAK OFF message will appear on the
DIC. Both traction control and StabiliTrak are
automatically disabled in this condition.
The traction control system is part of the StabiliTrak
system. Traction control limits wheel spin by reducing
engine power to the wheels (engine speed
management) and by applying brakes to each individual
wheel (brake-traction control) as necessary.
The traction control system is enabled automatically
when the vehicle is started. It will activate and the
StabiliTrak light will flash if it senses that any of the
wheels are spinning or beginning to lose traction while
driving. If traction control is turned off, only the
brake-traction control portion of traction control will
work. The engine speed management will be disabled.
