Tire Pressure Monitor TPM*

The concept

RDC monitors the tire inflation pressure in the
four mounted tires during a trip. The system
notifies you if there is a significant loss of pres-
sure 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, such as
a compact spare wheel, has been mounted, or if
TPM is temporarily malfunctioning due to other
systems or devices using the same radio fre-
quency.

Status indicator on the Control Display

The color of the tires 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.

One wheel yellow

There is a flat tire or substantial loss of tire pres-
sure in the indicated tire. A message appears on
the Control Display.

All wheels yellow

There is a flat tire or substantial loss of tire pres-
sure in several tires. A message appears on the
Control Display.

Gray

The system cannot detect a puncture.
Possible reasons for this:

TPM is being reset

Temporary malfunction caused by systems
or devices using the same radio frequency

Malfunction

Resetting the system

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

changed, reset the system.
