Flat Tire Monitor FTM*

The concept

The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
If a tire loses pressure, its rolling circumference
changes, and this in turn alters the speed of
rotation. This change is detected and is reported
as a flat tire.

Functional requirement

In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.

Each time you correct the pressure in a
tire, or change a wheel or tire, the system

must be reinitialized.

<

System limitations

The Flat Tire Monitor is unable to warn the driver
of sudden, severe tire damage caused by exter-
nal factors, nor can it identify the gradual loss of
pressure that will inevitably occur in all four tires
over a lengthy period of time.

In the following situations, the system could be
delayed or malfunction:

>

System has not been initialized

>

Driving on snowy or slippery road surface

>

Performance-oriented style of driving: slip in
the drive wheels, high lateral acceleration

>

Snow chains are attached

When the vehicle is driven with a space-saver
spare tire

, the Flat Tire Monitor can-

not function.

Initializing the system

The initialization is completed during driv-
ing, which can be interrupted at any time.

When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system if you are driving
with snow chains or a space-saver spare tire
