Fig. 15: Identifying Cruise Control Function - Shown On Engine 111 Euro3/4

Task

Maintaining the preselected vehicle speed constant irrespective of the engine load, without operation of the
accelerator pedal.

Function

The cruise control function is integrated in the engine control unit. It can be activated from > 40 km/h with the
cruise control 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:



pushing the cruise control push-button switch (S40) or variable cruise control push-button switch (S40/4)
into the "OFF" position



Operating the service brake



Moving selector lever into position "N"



Control intervention function of traction system

Vehicles with column sleeve module (MRM)

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.
