Vehicle with a permissible gross mass of up to 3.5 t: the limiter limits the vehicle's speed. To reduce the speed swiftly to the set speed, the limiter applies the brakes automatically.
Vehicle with a permissible gross mass of over 3.5 t: the limiter limits the vehicle's speed.
Variable: for speed limits, e.g. in built-up areas.
Permanent: for long-term speed restrictions, e.g. when driving in winter tyre mode.
The variable limiter is operated using the corresponding steering-wheel buttons. You can store any road speed above 20 km/h. You can also perform settings while the vehicle is stationary if the vehicle has been started.
If you exceed the set speed with the variable limiter by over 3 km/h, the 
symbol flashes in the instrument display. The Limiter set speed exceeded message appears. The flashing stops as soon as the speed drops below the set speed again.
If you fail to adapt your driving style, the limiter can neither reduce the risk of an accident nor override the laws of physics. It cannot take into account road, weather or traffic conditions. The limiter is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, braking in good time and for staying in your lane.
The status of the limiter and the stored speed are shown in the multifunction display.
If you depress the accelerator pedal beyond the pressure point (kickdown), the limiter switches to passive mode.
If you exceed the set speed with the variable limiter by over 3 km/h, the symbol flashes in the instrument display. The Limiter set speed exceeded message appears.
If the driven speed drops below the stored speed.
If the stored speed is called up.
If you store a new speed.
