Indication of a flat tire

The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat

tire or substantial loss of tire pressure.

1.

Reduce your speed and carefully stop the
car. Avoid sudden braking and steering
maneuvers.

2.

Identify the damaged tire. To do so, check
the tire pressure using the M Mobility Sys-
tem, refer to Producing the tire inflation
pressure on page

208

.

3.

Repair the flat tire with the M Mobility Sys-
tem, refer to page

207

.

Malfunction

The warning lamps come on in yel-
low. A message appears on the Con-
trol Display. The Flat Tire Monitor has
a malfunction or has failed. Have the

system checked as soon as possible.

Tire Pressure Monitor TPM*

The concept

TPM checks the inflation pressures of the four
mounted tires. The system notifies you if there
is a significant loss of pressure in one or more
tires.

Functional requirement

In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.

Each time a tire inflation pressure has
been corrected or a wheel or tire has been

changed, reset the system.

<

System limitations

TPM cannot warn you in advance of sud-
den severe tire damage caused by out-

side influences.

<

The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics has been
mounted, or if TPM is temporarily malfunction-
ing due to other systems or devices using the
same radio frequency.

Status indicator on the Control Display

The color of the wheels represents the status of
the tires and the system.
TPM takes into account that tire pressures
change while the vehicle is being driven. The
tire pressures do not need to be corrected
unless the TPM instructs you to do so by means
of color indicators.

Green

The tire inflation pressure corresponds to the
established target value.
"TPM active" appears on the Control Display.
