Speed control cruise control
Function of cruise control
Cruise control regulates the speed to the value
selected by the driver.
If you accelerate to overtake, for example, the
stored speed is not deleted. If you remove your
foot from the accelerator pedal after overtaking,
cruise control will resume speed regulation back
to the stored speed.
Cruise control is operated using the correspond‐
ing steering wheel buttons. You can store any
speed above 15 mph (20 km/h) up to the maxi‐
mum design speed.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nize dangers (
