GMC 2007 Envoy - Manual (Page 176)

Cruise Control
Your vehicle has cruise
control. The controls are
located on the end of
the turn signal/
multifunction lever.
R (On): Move the switch to this position to turn
the cruise control system on.
S
(Resume/Accelerate): Move the switch to this
position to resume a set speed or to accelerate.
T (Set): Press this button, located at the end of
the lever, to set a speed.
9 (Off): Move the switch to this position to turn
the cruise control system off and cancel memory
of a set speed.
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).
If you apply the brakes, the cruise control shuts 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.
