There is a display you can access withing the On Board Computer menu thats called Tire Presure Info or RDK info or somthing like that (can't remember know the exact wording) that will display the diference in pressure on each tire with the factory pressure INDEPENDANT of the tire temperature.
I.e. the TMPS measures not only the pressure in the tires but also the temperarure and thus whatever the temperature inside the tires is, it calculates to what pressure it corresponds at the standard 20*C. So the display will show you the difference to the factory pressures measured at the standard 20*C inspite what ever temperature each tire has.
So when you fill the pressures always use that delta display.
And for the record my TMPS is always sport on with my digital and analog gauses too
So when you fill your tires with air, does it give you an audio update of the pressure, or do you have to run back to the driver's seat to check the pressure, run back to give more air, check pressure, run back to give less air, etc ....
The menu item referred to by Carlos is in fact called "TPC: Info pressure".
After calling it up on the display, on the rare occasions when one or more of the tires has lost pressure, I wind down the door windows and check the readings from the outside of the left and right side of the car in turn after adding some air. Since this is so rarely necessary if you ignore minimum variations of only "-0.1" bar or "-1" psi, it is no hassle. (To explain that last statement, these "minimal" variations might be the result of true corrected pressure dropping from, for instance, 33.51 psi to 33.49 psi, if the cut-off between displayed pressures of 33 and 34 psi is set in the control unit at 33.50 psi).
Some people seem to be making living with the TPM system unnecessarily difficult for themselves because they have not taken a few minutes to read the relevant notes in the manual and to absorb and understand the concept.
PS: Just don't ask me to explain why the system is sometimes referred to in English literature as TPC and sometimes as TPMS.
