Cruise Control (Option)
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 or move the cruise switch
to off, the cruise control will shut off.

Cruise control can be dangerous on
