Cruise Control (Option)
With cruise control, you can
maintain a speed of about
25 mph (40 k m 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 push the clutch pedal, if
you have a manual transaxle, the cruise control shuts off.
