The messages from the tire pressure monitor (TPM) system are shown in the left multifunction display (A1p13) and in the right multifunction display (A1p15) of the instrument cluster (A1).

A distinction is made between the following:
- Menu displays and
- warning messages

The menu displays can be called up in the instrument cluster using the TPM [RDK] menu.
The warning messages appear automatically.
Depending on the warning message the tire pressure monitor warning lamp (A1e66) is also actuated.
