You have attempted to start the engine
while the automatic transmission was set to
reverse gearR or drive positionD.
Shift the automatic transmission to park positionP or neutral
positionN (

Tire Pressure Monitor
Inoperative
The Advanced TPMS or a wheel sensor is
malfunctioning.
Have the Advanced TPMS checked by an authorized

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. Continued
driving with a flat tire will cause excessive
heat build-up and possibly a fire.
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adverse-
ly affect handling and fuel economy, and are
more likely to fail from being overheated. Do
not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.

Mercedes-Benz Center.
As soon as all wheels with sensors have been mounted, the
Advanced TPMS is switched back on after driving for several
minutes.
Tire Pressure Monitor
Currently Unavailable
The Advanced TPMS is unable to monitor
the tire inflation pressure due to:
a nearby radio interference source
the on-board voltage is too low
excessive wheel sensor temperatures
As soon as the causes for the malfunction are no longer present,
the Advanced TPMS automatically becomes active again after a
few minutes of driving.
