lity

In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.

Functional requirement

To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.

The initialization must be repeated after
every correction of the tire inflation pres-

sure and after every tire or wheel change.

System limits

The Flat Tire Monitor cannot indicate sudden
severe tire damage caused by outside factors
and does not detect a natural, even pressure
drop in all four tires.
In the following situations, the system could be
delayed or malfunction:

System has not been initialized

Driving on snowy or slippery road surface

Sporty driving style: slip in the drive wheels,
high lateral acceleration

Driving with snow chains

Initializing system

The initialization finishes during driving,
which can be interrupted at any time.

When driving resumes, the initialization is con-
tinued automatically. The system is initialized
after this activation phase. The system is not
initialized when traveling with snow chains
