The cruise control must maintain the preselected speed constant irrespective of the load condition, without the accelerator pedal being operated.

The cruise control function can be actuated from > 40 km/hour using the Cruise control push-button switch. The engine control unit operates the throttle valve actuator for the cruise control function with the aid of the input signals and the position of the cruise control switch.

The cruise control mode is switched off by:

Moving the cruise control switch into OFF position
Actuation of the service brake (CAN message)
Moving selector lever into position "N"
Operation of the clutch pedal
Control intervention function of the traction system.

The signals from the push-button switch for the cruise control are detected by the steering column module and transmitted to the CAN data bus.

The speed signal is transmitted by the traction system control unit (ESP) via the CAN to the engine control unit.

The software for the Cruise control is stored according to model and equipment either in the ESP control unit or in the City Assist System control unit.

Variable speed limiter (VSL), except

Switching in the variable speed limit takes place through pressing the Cruise control push-button switch (yellow light emitting diode lights up).

The vehicle speed limit is set by means of the variable cruise control switch.

If the braking effect in overrun mode is not sufficient to maintain the speed at a high gradient, a chime will request the driver to brake. Vehicles with Distronic (DTR) are braked.

Deviating functions compared to cruise control:

Variable speed-governor function (VGB) adjustable from 30 km/h (20 mph) to the top speed of the vehicle.
The accelerator pedal must be actuated further.
When the brakes are applied the variable speed limit is not switched off.
When the ignition is switched OFF the preset speed data remain stored in the variable cruise control system.
