Tire Pressure Monitor TPM*

The concept

Check the inflation pressure in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.

Functional requirement

The system has to have been reset at the cor-
rect inflation pressure; otherwise, a reliable
reporting of a flat tire is not assured.
Always use wheels with TPM electronics to
assure a trouble-free function of the system.

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

changed, reset the system.

System limitations

It is impossible to provide advance warn-
ing of sudden, severe tire damage caused

by outside influences.

The system does not function correctly if it has
not been reset. For example, a flat tire may be
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:

when a wheel without TPM electronics is
installed.

when other systems or devices that use the
same radio frequency interfere with TPM.

Status display

The current status of the TPM Tire Pressure
Monitor can be displayed on the Control Dis-
play, e.g. whether or not the TPM is active.

"Vehicle Info"

"Vehicle status"

"Tire Pressure Monitor - TPM"

The status is displayed.

Status indicator on the Control Display

The color of the tires represents the status of
the tires and the system.
A change in the inflation pressure during driving
is taken into account.
A correction is only needed if TPM indicates it.

Green

The inflation pressure corresponds to the
desired state.
"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.

All wheels yellow

There is a flat tire or substantial loss of tire
pressure in several tires.

The system was not reset after a wheel
change and will thus issue warnings at the
last initialized inflation pressures.
