Flat Tire Monitor

The concept
System limits
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires
as you drive. The system provides an
alert whenever the inflation pressure
drops significantly in relation to the
pressure another tire.
The Flat Tire Monitor cannot indi-
cate 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:
The check of the tire inflation pressure
is based on monitoring the relative
speeds of the wheels. A flat is detected > When driving on snow-covered or
and reported on the basis of a deviation
in certain speed ratios.
slippery road surfaces
> In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
> False alarms and undetected loss of
pressure may occur when you are
driving with snow chains fitted.
The Brake Force Display lights up in
two stages, depending on how force-
fully you apply the brakes.
Functional requirement
To ensure reliable operation, the sys-
tem should have been initialized with
the correct tire inflation pressure.
The display has two levels:
> Normal braking:
The brake lamp 1 and the center
brake lamp light up
> Heavy braking and braking with ABS:
The brake lamps 1 and 2 light up
together with the center brake lamp.
