switching contacts (e.g. storing the speed). The safety contact must close simultaneously 
so that the input is accepted.

SAFETY INFORMATION: THROTTLE CONTROL, CRUISE CONTROL SYSTEM - AS30.00-Z-9999ZZ 

MODEL all  

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.

Kickdown 
switch task

Identify kickdown position of accelerator pedal, in order to influence 
transmission control, cruise control, variable speed limiter and 
Distronic.

 

 

Kickdown 
switch design

Up to approx. 6/02 designed as an electrical switch (S16/6). As of 
approx. 7/02 (without engine 166) the electrical switch is replaced by 
the Kickdown simulator (spring).
