RD. system description
WARNING: This page is about a different car, the 2009 MINI Cooper and 2008 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.
RD. 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 RD. 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:
WARNING CHART
| 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 |
ADVANTAGES OF RD.
| Advantages of RD. | |
| 1. Safety | early warning in the event of rapid loss of pressure |
| warning of loss of tire pressure through normal diffusion | |
| 2. Comfort | unchanging ride comfort |
| instruction to check tire pressure as necessary | |
| 3. Service life, economy | minimization of tire wear |
| minimization of fuel consumption | |
| 4. New developments | allow tires with emergency running characteristics to be fitted |
| no spare wheel if tires with emergency running characteristics are fitted (saves weight) | |
