TIRE PRES. MONITOR
CURRENTLY
UNAVAILABLE
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

Remove any extra wheel sensors from the ve-
hicle.
As soon as the causes of the malfunction have
been removed, the tire inflation pressure moni-
tor automatically becomes active again.

DRIVE TO WORKSHOP
The tire inflation pressure monitor or a
wheel sensor is malfunctioning.

Have the tire inflation pressure monitor
checked by an authorized Mercedes-Benz
Center.
A wheel without proper sensor was in-
