RDC system description
RDC permanently monitors the tire pressure and the temperature in the tires, both while the vehicle is being driven and when it is stationary. Data is transmitted via data telegram by the wheel electronic units to the antennas installed in the wheel housing and on to the RDC control unit. There, the data received is compared with the stored limit values.
After correcting the air pressure with the engine off and the ignition on, press the Set button and hold (approx. 6 seconds) until the words "Set tire pressure" appear in the instrument cluster (instrument cluster high) or the yellow LED lights up (basic instrument cluster).
If the limit values are exceeded, the driver will be warned via the instrument cluster in two stages, as follows:
TYRE PRESSURE SPECIFICATION
| Loss of tire pressure | Warning |
|---|---|
| Drop in tire pressure of 0.2 to 0.4 bar | Yellow LED on basic instrument cluster or Text: "Check tire pressure" on instrument cluster high Gong: no |
| Drop in tire pressure of more than 0.4 bar | Red LED on basic instrument cluster or Text: "Tyre failure" on instrument cluster high Gong: yes |
