Flat Tire Monitor
The concept
As you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
In the event of tire pressure loss, the
rolling radius of the tire changes, and
thereby the rotational speed of the
wheel. This change is detected, and a
flat tire warning is issued to the driver.
Functional requirements
To ensure a reliable flat tire warning,
the system must be initialized with the
correct tire inflation pressures.
Initialize the system immediately
after you have corrected a tire
inflation pressure, or changed the tire
or wheel.<
System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
