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.
The StabiliTrak
®
button
is located on the
instrument panel.
StabiliTrak
®
and part of the traction control system can be
turned off or back on by pressing the StabiliTrak
®
button.
All-wheel drive vehicles must be in all-wheel drive mode
to turn the system on or off. Four-wheel-drive vehicles
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
®
is off, but will not be able to use the
engine speed management system. See “Traction
Control Operation” next for more information.
