Tire Pressure Monitor System Reactivation
CAUTION:
The warning system can only operate in a reliable manner if correct tire pressures are set. If an incorrect tire inflation pressure is set, the system will monitor the pressure according to the incorrect value.
NOTE:
In the event of air pressure changes by the driver, or of a wheel replacement or a tire change, new air pressure values in the TPM [RDK] control unit are detected automatically by filling detection. Manual reactivation is merely planned as a stopgap solution if automatic filling detection fails.
- Ensure inflation pressure of all 4 tires is set to specification.
- On-board computer: Service > Tires.
- Swipe downwards on the Touch Control on the left-hand side of the steering wheel.. See Fig 1. The USE CURRENT PRESSURES AS NEW REFERENCE VALUES message is shown in the multifunction display.
- Press OK to confirm the restart. The RUN FLAT INDICATOR RESTARTED message is shown in the multifunction display.
- Current warning messages are deleted and the YELLOW warning lamp goes out.
- After the vehicle has been driven for a few minutes, the system checks whether the current tire pressures are within the specified range. The current tire pressures are then accepted as reference values and monitored.
