Hummer 2008 H2 - Manual (Page 276)

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 StabiliTrak ® button
if both systems (traction control and StabiliTrak ® ) were
previously on. To disable both traction control and
StabiliTrak
® , press and hold the button for five seconds.
Traction control and StabiliTrak ® can be turned on
by pressing and releasing the StabiliTrak ® button if
not automatically shut off for any other reason.
When the TCS or StabiliTrak ® system is turned off,
the StabiliTrak ® light and the appropriate TCS off
or StabiliTrak ® 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 4-39.
When the transfer case is in Four-Wheel-Low Lock,
the stability system is automatically disabled, the
StabiliTrak
® light will come on and the STABILITRAK
OFF message will appear on the DIC. Both traction
control and StabiliTrak
® are automatically disabled in
this condition.
