Possible cause/consequence
Possible solution
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
vehicle.
As soon as the causes of the malfunction have
been removed, the tire inflation pressure moni-
tor automatically becomes active again.
TIRE PRES. MONITOR
NOT OPERATIONAL
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-
stalled.

Have the wheels checked.
Warning!
G

the ability to steer or brake the vehicle.
