Pontiac 2004 Grand Prix Owner's Manual page 113

With cruise control, you can maintain a speed of
approximately 25 mph (40 km/h) or more 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 you apply your brakes, the cruise control
shuts off.
If your vehicle is in cruise control and either the
Traction Control System (TCS) or the Enhanced Traction
System (ETS) begins to limit wheel spin, the cruise
control will automatically disengage. See Traction
Control System (TCS) on page 4-10 and Enhanced
Traction System (ETS) on page 4-11 . When road
conditions allow you to safely use it again, you may
turn the cruise control back on.
