Function


Component Identification:






When the CC [TPM] switch is operated, two switching contacts are always activated simultaneously. The actual input takes place by closing the switching contacts (storing the target speed). The safety contact (S40/4s5) must close simultaneously so that the entry is accepted.

The DISTRONIC distance potentiometer allows the driver to adjust the target distance to the preceding vehicle to suit his/her own personal taste.
The setting range of the target distance is divided into six increments and is approx. 1.0 s to 2.0 s depending on vehicle speed.
Within this setting range the legally prescribed minimum distance is always guaranteed.

The CC [TPM] switch signals are read in by the steering column module (N80) and transmitted via the drive CAN to the ESP control unit (N47-5) for evaluation.
