Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center.◀
Tire Pressure Monitor TPM
The concept
The tire inflation pressure is measured in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires.
Functional requirements
The system must have been reset while the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits
Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pres‐
sures.
The system is inactive and cannot indicate a flat
tire:
▷
For a mounted wheel without TPM electron‐
ics.
▷
When the TPM is disturbed by other sys‐
tems or devices with the same radio fre‐
quency.

The status is displayed.
Status indicator on the Control Display
The tire and system status is indicated by the
color of the tires.
A change in the tire inflation pressure during
driving is taken into account.
A correction is only necessary if this is indicated
by the TPM
Wheels, green
The tire inflation pressure is equal to the target
state.
One wheel is yellow
A flat tire or major drop in inflation pressure in
the indicated tire.
All wheels are yellow
▷
A flat tire or major drop in inflation pressure
in several tires.
▷
The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
▷
A flat tire in one or more tires while the sys‐
tem is being reset.
Wheels, gray
The system cannot detect a flat tire.
Reasons for this may be:
▷
TPM is being reset.
▷
Disturbance by systems or devices with the
same radio frequency.
▷
Malfunction.
