2007 GMC YUKON XL DENALI cruise control

Using Cruise Control on Hills
How well your cruise control will work on hills
depends upon your speed, load, and the
steepness of the hills. When going up steep hills,
you may have to step on the accelerator pedal
to maintain the vehicle’s speed. When going
downhill, you may have to brake or shift to a
lower gear to keep the vehicle’s speed down.
Of course, applying the brake takes you out
of cruise control. Many drivers nd this to be too
much trouble and do not use cruise control on
steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the cancel button on the steering wheel.
Press the On/Off button on the steering
wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.
Exterior Lamps

control is located on the
instrument panel to
the left of the steering
wheel.

Traction Control Operation
The traction control system is part of the
StabiliTrak®system. Traction control limits wheel
spin by reducing engine power to the wheels
(engine speed management) and by applying
brakes to each individual wheel (brake-traction
control) as necessary.
The traction control system is enabled
automatically when you start your vehicle. It will
activate and the StabiliTrak
®light will ash if
it senses that any of the wheels are spinning or
beginning to lose traction while driving. If you turn
off traction control, only the brake-traction
control portion of traction control will work. 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
®, 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.
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
®light will ash and the
cruise 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 200.
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.
