Possible cause/consequence
The tire inflation pressure monitor* is un-
able to monitor the tire inflation pressure
due to:
the presence of several wheel sensors
in the vehicle
excessive wheel sensor temperatures
a nearby radio interference source
unrecognized wheel sensors installed
The tire inflation pressure monitor or a
wheel sensor is malfunctioning.
A wheel without proper sensor was in-
stalled.
G
Possible solution
Remove any extra wheel sensors from the
vehicle.
As soon as the causes of the malfunction have
been removed, the tire inflation pressure moni-
tor automatically becomes active again.
Have the tire inflation pressure monitor
checked by an authorized Mercedes-Benz
Center.
Have the wheels checked.
