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.

Vehicles with EZS control unit without column sleeve module (MRM)
The signals from the push-button switch for the cruise control are detected by the control unit EIS and
transmitted to the CAN data bus.
Vehicles without EZS control unit
The signals from the cruise control switch are transmitted directly to the engine control unit.
Vehicles with manual transmission (MT)
Cruise control remains active during gear change, in other words the cruise control is not switched off when the
clutch is operated.
Traction systems control unit
Transmits the vehicle speed signal via CAN to the ME control unit.
