transmit signals to the instrument cluster. Reactivation of the TPM system can be initiated via the left multifunction steering wheel button group
(S110) and the right multifunction steering wheel button group (S111) on the multifunction steering wheel and the instrument illumination rheostat
and reset button (A1r1) on the instrument cluster.
Note:
When the TPM system is reactivated filling detection is also restarted.
