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.

switch position

in footwell behind accelerator pedal

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
