Cruise control and limiter
Function of cruise control
Cruise control accelerates and brakes the vehicle
automatically in order to maintain a previously
stored speed.
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.
You operate cruise control using the cruise con‐
trol lever. You can store any speed above
30 km/h.
