GF30.20-P-2100GR Component Description For The CC [TPM] Switch
- with CODE (219) Distronic (DTR)
- with CODE (491) USA version







The CC [TPM] switch is located at the top left of the steering column.

Task
The CC [TPM] switch has the following tasks:
- Activate/deactivate the function DISTRONIC PLUS
- Increase or decrease setting/nominal speed in 1 mph or in 10 mph steps (two settings) for DISTRONIC and Downhill Speed Regulation
- Set target proximity for DISTRONIC











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 (S40s5) 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.
