NOTE: The adaptive pressure limits can be read out using the Porsche System Tester 2 (Menu/Actual values) and used for trouble-shooting.

Limits mean: no other value can be read out.

Maximum values does not mean that testing or repair work is necessary.

Carry out remedial work only in the event of complaints.
