All-Wheel Drive (Awd) System; Steering; Power Steering - GMC 2008 Yukon Denali Owner's Manual

The engine speed management will be disabled. In this
mode, engine power is not reduced automatically and the
driven wheels can spin more freely. This can cause the
brake-traction control to activate constantly.
Notice: If you allow the wheel(s) of one axle to spin
excessively while the StabiliTrak
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.
The traction control system 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
control will automatically disengage. When road
conditions allow you to use cruise again, you may
re-engage the cruise control. See Cruise Control on
page 3-13.

StabiliTrak 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 for service.

All-Wheel Drive (AWD) System

With this feature, engine power is sent to all four wheels
all the time.
This is like four-wheel drive, but there is no separate
lever or switch to engage or disengage the front axle. It
is fully automatic, and adjusts itself as needed for
road conditions.

Power Steering

If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
