Function
Tire pressure monitoring (TPMS) reminds the driver of low tire pressure in one or more tires.
Tire pressure monitoring is automatic and monitors the car's tire pressures in all four wheels. The system is activated when the speed exceeds 20 km/h.
Four tire pressure sensors measure the tire pressure and transmit the pressure values via radio waves to the control module which is located in the luggage compartment.
The tire pressure sensor is fitted in the wheel rim and functions as valve, sensor and transmitter.
The control module listens to the information during the first few minutes in order to ascertain the position of each tire pressure sensor. The system is self-programming, which means that it is possible to swap around the wheels without the need to recalibrate the control module.
The information on incorrect tire pressure is sent on the I-bus. The message is shown as a warning or alarm message in the main instrument unit's display.
