Tire Pressure Monitor
Wheel Sensor MissingVehicles with Advanced TPMS*:
One or more wheels without
appropriate wheel sensors
mounted (e.g. spare wheel).
The respective tire is indicated by
--- instead of the tire inflation
pressure in the multifunction
display.
Have the Advanced TPMS* checked by an
authorized Mercedes-Benz Center.
Have appropriate wheel sensors installed
by an authorized Mercedes-Benz Center.
Tire Pressure MonitorCurrently
UnavailableThe TPMS or Advanced TPMS* is
unable to monitor the tire pres-
sure due to a nearby radio interfer-
ence source.As soon as the causes for the malfunction
are no longer present, the TPMS or
Advanced TPMS* automatically becomes
active again after a few minutes driving.
Warning!G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
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.
Warning!G
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.
