GMC 2007 Savana - Manual (Page 237)

Pressing and holding
the StabiliTrak
® button
located on the
instrument panel for
more than five seconds
can turn off StabiliTrak
®
and part of the
traction control system.
For your safety, the system can only be disabled
when the vehicle speed is less than 20 mph
(32 km/h). You will hear three chimes and the
StabiliTrak
® not ready light will come on.
To turn on the StabiliTrak ® system, press the
StabiliTrak ® button again. StabiliTrak ® will
automatically turn back on when the vehicle speed
exceeds 20 mph (32 km/h). You will hear one chime
and the StabiliTrak
® not ready light will turn off.
When the StabiliTrak ® 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. See If Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 258.
StabiliTrak ® System Operation
The StabiliTrak ® system is normally on, except
when the system is initializing or has been
disabled with the StabiliTrak
® button. The
StabiliTrak ® system will automatically activate to
assist the driver in maintaining vehicle directional
control in most driving conditions. When activated,
the StabiliTrak
® system may reduce engine
power to the wheels and apply braking to individual
wheels as necessary to assist the driver with
vehicle directional control. If your vehicle is
in cruise control when the system activates, the
StabiliTrak
® indicator light on the instrument panel
will flash, and the cruise control will automatically
disengage. When the StabiliTrak
® system is
no longer active, you may re-engage the cruise
control. See Cruise Control on page 151.
