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.
