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
Press the EDC button repeatedly:

>
"Normal": one LED lights up.
"Sport": both LEDs light up.

2.
Start the engine, but do not start driving.
Press the button for approx. 5 seconds.
After the button is released, the warning
lamp lights up in yellow for several sec-
onds in the instrument cluster, refer to
Indication of a flat tire. The message "Initial-
izing FTM ..." appears on the Control Dis-
play for a few seconds.
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
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
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change.<
3.
Start to drive.
The initialization finishes during driving
without feedback.
