The initialization finishes during driving
without feedback.

Indication of a flat tire

The warning lamp lights up red. A mes-
sage appears on the Control Display.
In addition, an acoustic signal sounds.

There is a flat tire or extensive inflation pressure
loss.

1.

Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.

2.

Identify damaged tire. To do this, check the
tire inflation pressure using the M Mobility
System, refer to Producing tire inflation
pressure on page

.

3.

Repair flat tire with M Mobility System, refer

TPM Tire Pressure Monitor*

The concept

TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.

Functional requirement

In order to assure the reliable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.

Reset the system again after each correc-
tion of the tire inflation pressure and after

every tire or wheel change.

<

System limits

TPM cannot announce sudden serious
tire damage caused by external influ-

ences.

<

The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, or if TPM is temporarily interfered
with by other systems or devices which use the
same radio frequency.

Status display on Control Display

The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.

Green

The tire pressure matches the learned set state.
"TPM active" is displayed on the Control Dis-
play.

One wheel is yellow

Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.
