Notice: If the StabiliTrak
®
light comes on due to
heavy braking and/or because the traction control
system has been continuously active, do not
allow the wheel(s) of one axle to spin excessively. If
you do, you may be causing damage to the
transfer case. This could lead to costly repairs not
covered by your warranty.
Notice: If you allow the wheel(s) of one axle to spin
excessively while the StabiliTrak
®
, ABS and brake
warning lights and the SERVICE STABILITRAK
message are displayed, you could damage the
transfer case. The repairs would not be covered by
your warranty. Reduce engine power and do not
spin the wheel(s) excessively while these lights and
this message are displayed.
StabiliTrak
®
may activate on dry or rough roads or
under conditions such as heavy acceleration while
turning or abrupt upshifts/downshifts of the transmission.
When this happens, you may notice a reduction in
acceleration, or may hear a noise or vibration. This
is normal.
If your vehicle is in cruise control when the system
activates, the StabiliTrak
®
light will blink, and the cruise
control will automatically disengage. When road
conditions allow, you may re-engage the cruise control.
See Cruise Control on page 3-11.
StabiliTrak
®
will turn off automatically if a problem is
detected in the system. The StabiliTrak
®
light will come
on and SERVICE STABILITRAK will be displayed on
the DIC. For vehicles without a DIC, the StabiliTrak
®
light and the StabiliTrak
®
service light will both come on.
If the SERVICE STABILITRAK message (or StabiliTrak
®
service light) does not clear itself after restarting the
vehicle, you should see your dealer for service.
Adding non-GM accessories can affect your vehicle’s
performance. See Accessories and Modifications
on page 5-3 for more information.
