maintain a speed of about
25 mph (40 km/h) or more
without keeping your foot

Cruise control does not
work at speeds below about
25 mph (40 km/h).
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.
