Principle of Operation

Initialization

After the tires are replaced, rotated or if their inflation pressures are adjusted, then the wheel transmitter modules must be initialized using the RDC function in the "Settings" menu of the Control Display.

During initialization the following processes are performed:

- Individual wheel recognition (Identification of wheel transmitter modules).
- Wheel position assignment.
- Plausibility check (setpoint pressures checked).
- Adoption of setpoint pressures as specified pressures.

The RDC then learns the wheel transmitter module position.

The minimum air pressure accepted by the RDC on initialization is 1.7 bar (24.7psi). If the tire pressures deviate more than 0.4 bar (6psi) per axle the initialization is rejected after a plausibility check.

1.3 bar is the lowest pressure detected by the wheel transmitter module. At that point, a tire failure warning will always be issued.

Complete initialization can take up to 30 minutes. Only the actual driving time over 6 km/h is taken into account. During initialization, the CC message "Initializing RDC!" is displayed on the Instrument Cluster.







When the initialization from the Control Display is activated, the wheels appear black and the pressures are not shown.




Once initialization is complete, the tires of the car on the graphic turn green and pressure values are shown for each tire.
