Resetting Tire Pressure Monitoring System

If the driver changes to the air pressure, the wheels or a tire, the new air pressure values are set automatically in the TPM control unit (N88) by the filling detection system. Manual reactivation is only provided as a stop-gap solution if the automatic detection system fails.

The following procedures must be carried out for activation.
- Correct the air pressure at each wheel.
- Switch on ignition (circuit 15 On).
- Using the scroll forward/back button (S110s1) select the tire pressure monitor system.
- Press the trip odometer reset button (A1s3). The previous display changes to the selection screen with preselection "No".
- Press the "+" button on the + and - push-button (setting specific functions and volume control) (S111s1) on the multifunction steering wheel. The selection screen with selection "Yes" appears for approx. 2 seconds and then changes immediately to the confirmation screen.
- Pressing the other keys leads to termination of the activation process.
- The system message " Tire pressure displayed after driving for several minutes" appears immediately after the engine starts.
- If activation is carried out while the engine is running, this message appears with a time delay of approx. 30 seconds.
