Cruise control and limiter
▌Function of cruise control
Cruise control regulates the speed to the value
selected by the driver.
If you accelerate to overtake, forexample, 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 can store any speed above 20 km/h up to the
maximum design speed or up to the set winter
tyre limit.
Observe the notes on driving systems and your
