GMC 2008 Acadia - Manual (Page 279)

The StabiliTrak ® light will
flash on the instrument
panel cluster when
the system is both on and
activated.
You may also feel or hear the system working; this is
normal.
The traction control disable
button is located on the
instrument panel below the
climate controls.
The traction control part of StabiliTrak ® can be turned
off by pressing and releasing the traction control disable
button.
Traction control can be turned on by pressing and
releasing the traction control disable button if not
automatically shut off for any other reason.
When the traction control system is turned off, the
StabiliTrak
® light and the appropriate traction control off
message will be displayed on the DIC to warn the
driver. Your 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, you may still hear system noises as a result of the
brake-traction control coming on.
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 want to “rock” your 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 If Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-20.
