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 more information, see StabiliTrak
®
Indicator Light on
page 3-36.
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 4-19.
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system is no longer active, you may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 3-11.
The StabiliTrak
®
system may also turn off automatically if
it determines that a problem exists with the system. If the
problem does not clear itself after restarting the vehicle,
you should see your dealer/retailer for service.
