Pontiac Montana SV6 2007 Owner's Manual page 185

Cruise control allows a speed of approximately
25 mph (40 km/h) or more to be maintained
without keeping your foot on the accelerator. This
is helpful on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).
When the brakes are applied, the cruise control
shuts off.
If the vehicle is in cruise control and the Traction
Control System (TCS) begins to limit wheel spin,
the cruise control will automatically disengage. See
Traction Control System (TCS) on page 365. When
road conditions allow, the cruise control can be
used again.
Setting Cruise Control
CAUTION:
{
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do not
want to. You could be startled and even
lose control. Keep the cruise control switch
off until you want to use cruise control.
1. Push the button at the end of the cruise
control lever to turn the cruise control on.
2. Accelerate to the desired speed.
3. Push down on the cruise control lever and
release it. This will set the speed in cruise
control.
4. Remove your foot from the accelerator pedal.
