GMC 2008 Acadia - Manual (Page 154)

Cruise Control
With cruise control, you can maintain a speed of
about 25 mph (40 km/h) or more without keeping
your foot on the accelerator. This can really help on
long trips. Cruise control does not work at speeds
below about 25 mph (40 km/h).
When you apply your brakes, cruise control is turned off.
{ CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
The cruise control
buttons are located
on left side of the
steering wheel.
