The sensors remain active for 15 minutes after the car stops, then they go into standby mode.
In this mode, the sensors give a signal if the difference between two successive measured pressure values exceeds 68 mbar or if the pressure has changed by more than 68 mbar since the last signal was issued (as a result of tire cooling).
Tires are considered cold 1 hour 45 minutes after stopping the car.
The minimum detection time for tire air leaks is about 15 minutes.
Message «Inflate tires for freeway driving» issued (for reference), if the vehicle is moving at a speed of more than 170 km/h for 3 minutes and if the pressure in at least one tire is 400 mbar lower than specified for low speed. This message is not displayed at any speed when the tires are inflated for highway driving.
Threshold values of warning signals:
- cold tire pressure too high = tire pressure 700 mbar higher than prescribed;
- warm tire pressure too high = tire pressure 850 mbar higher than prescribed;
- tire pressure too low = tire pressure less than prescribed by 400 mbar;
- tire pressure too low = tire pressure 600 mbar below prescribed;
- different tire pressures = the pressure difference between the left and right wheels of the same axle is greater than 500 mbar.
Messages displayed on the scoreboard:
- «Puncture, change wheel» + Lighting of the STOP signal lamp + Highlighting the image of the corresponding wheel on the display in the instrument panel + Sound signal;
- «Set the required tire pressure» + highlighting the image of the corresponding wheel on the scoreboard;
- «Inflate tires for freeway driving» + Highlighting images of all wheels on the scoreboard;
- «Tire sensor defective» + extinction of the image of the corresponding wheel;
- «Electronics failure» + signal lamp on «service» + Extinguishing images of the corresponding wheels on the scoreboard.
Tire pressure information is not displayed on the instrument panel.
