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.

RISK OF INJURY - AS30.30-Z-0001-01A 
Never look directly into the laser beam. Do not attempt to suppress the natural reflex of the eyelids. 
Avoid direct skin contact with the laser beam. If eye damage is suspected, consult an eye specialist 
without delay.

Risk of injury!  
Class 2 lasers emit a visible radiation. Looking directly into the laser beam can result in damage to the eye. 
The reflected laser beam can likewise cause damage to the eye. 
For this reason, avoid reflections of the laser beam by using mirrors and similar aids. Laser beams may also 
cause skin damage. 
Safety instructions/precautions  
Never look directly into the laser beam.  
Do not attempt to suppress the natural reflex of the eyelids. 
 The eye is normally protected by defensive reactions including the reflex of the eyelid closing. 
Avoid direct skin contact with the laser beam.  
If damage to the eye is suspected, consult an eye specialist immediately.  
It is prohibited to further bundle the laser beam and thus to concentrate the energy (increasing the laser 
class).  
Only properly instructed personnel may be entrusted with the work on this equipment.
