Possible solution

Tire Pressure Monitor
Inoperative
No Wheel Sensors

The Advanced TPMS is deactivated be-
cause wheels without proper sensors were
installed.

Have the wheel sensors installed by an authorized
Mercedes-Benz Center.

As soon as all wheels with sensors have been mounted, the
Advanced TPMS is switched back on after driving for several
minutes.

Tire Pressure Monitor
Currently Unavailable

The Advanced TPMS is unable to monitor
the tire inflation pressure due to:

ț

excessive wheel sensor temperatures

As soon as the causes for the malfunction are no longer present,
the Advanced TPMS automatically becomes active again after a
few minutes of driving.
