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 156.
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 322 for more information.
All-Wheel Drive (AWD) System
Your vehicle has this feature. There is no lever or
switch to engage or disengage the front axle. It
is fully automatic and adjusts as needed for
road conditions. Your vehicle has an active
transfer case allowing two-wheel-drive operation
on dry roads. The transfer case will shift
automatically into all-wheel drive on slippery
surfaces. You may feel an extra shift when the
all-wheel drive engages.
