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

The cruise control function can be activated at speeds above 40 km/h with the cruise control switch. Using the input signals and the position of the cruise control switch, the engine control unit actuates the throttle valve actuator for the cruise control function.

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"
Control intervention function of the traction system.

The signals from the cruise control switch are detected by the steering column module and transmitted via the CAN data bus to the engine control unit.

The speed signal is transmitted by the ESP control unit via the CAN to the engine control unit.
