Stabilitrak System - GMC 2006 Yukon XL Owner's Manual

®
StabiliTrak System
Your vehicle may be equipped with the StabiliTrak
system which combines antilock brake, traction
and stability control systems and helps the driver
maintain directional control of the vehicle in most driving
conditions.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic checks
to ensure there are no problems. You may hear or
feel the system working. This is normal and does not
mean there is a problem with your vehicle. The system
should initialize before the vehicle reaches 20 mph
(32 km/h). In some cases, it may take approximately
two miles of driving before the system initializes.
If the system fails to turn on or activate, the STABILITY
SYS DISABLED or SERVICE STABILITY message
will be displayed. If the vehicle has gone through
heavy acceleration or braking during the first two miles
after starting your vehicle, the STABILITY SYS
DISABLED message may appear. If this is the case,
your vehicle does not need servicing. Turn your
vehicle off and back on again to reset the system.
If either message appears on the Driver Information
Center (DIC), and your vehicle hasn't gone through
hard acceleration or braking in the first two miles, your
vehicle should be taken in for service.
The STABILITY SYS ACTIVE message will appear on
the Driver Information Center (DIC) only when the
®
system is both on and activated. You may also feel or
hear the system working; this is normal. For more
information on the stability messages, see Driver
Information Center (DIC) on page 3-52.
®
StabiliTrak and part of the traction control system can
be turned off or back on by pressing the StabiliTrak
button. The vehicle must be in 2HI, 4HI or AUTO 4WD
to turn the system on or off.
When the system is turned off, the traction off light
will illuminate, and the STABILITY SYS DISABLED
message will appear on the DIC to warn the driver
that both the stability system and part of the traction
control system are disabled. Your vehicle will still have
brake-traction control when StabiliTrak
will not be able to use the engine speed management
system. See "Traction Control Operation" next for
more information.
