Carefully bring the vehicle to a halt, avoiding abrupt steering
and braking maneuvers. Observe the traffic situation around
you.

Check and adjust tire inflation pressure as required
(page 511).

If necessary, change the wheel (
page 629).

Restart the Run Flat Indicator* after adjusting the tire infla-
tion pressure values (
page 516).
Tire pressure monitor

Tire pressure monitor
inoperative
No wheel sensors
The Advanced TPMS* is deactivated be-
cause wheels without proper sensors were
installed.

Possible solution
Tire pressure monitor
currently unavailable
The Advanced TPMS* is unable to monitor
the tire inflation pressure due to:

a nearby radio interference source
