Warning!
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
Possible cause
The tire pressure monitor is using the cur-
rent pressure values as the basis for mon-
itoring.
The tire inflation pressure monitor* is un-
able to monitor the tire pressure due to:
the presence of several wheen sen-
sors in the vehicle
excessive wheel sensor temperatures
a nearby radio interference source
unrecognized wheel sensors installed
The tire pressure monitor or a wheel sen-
sor is malfunctioning.
A wheel without proper sensor was in-
stalled.
G
You may lose control of the vehicle. Contin-
ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.
Practical hints
What to do if ...?
Possible solution
Remove any extra wheel sensors from the
vehicle
As soon as the causes of the malfunction
have been removed, the tire pressure moni-
tor automatically becomes active again.
Have the tire inflation pressure monitor
checked by an authorized Mercedes-Benz
Center.
Have the wheels checked.
