Tire pressure monitor
Principle
The Tire Pressure Monitor monitors the tire
pressure and issues a warning if the tire pres-
sure has dropped.
General information
Sensors in the tire valves measure the tire in-
flation pressure and tire temperature.
Depending on the tires detected or registered,
the system displays the specified nominal
pressures on the control display and compares
them with the current tire pressures.
If tires are being used that are not specified
in the tire inflation pressure details on the ve-
hicle such as tires with special approval, the
system needs to be actively reset. The system
will then take over the actual tire inflation pres-
sures as the target pressures.
