Every so often after driving a significant distance I get the Correct TP advise on shutdown even though the pressures are fine. The next number of times I drive it doesn't do it. Every so often I get the message and screwy pressure readings, 38, 31 33, 35 etc. Next time out they're fine. Just ignore it and use the good old hand held tire gauge.

The TP as part of its job does meaure "pressure differential" - however you can reset the TP at anytime it is active.. download owner's manual from mbusa.com under Owner's Section

You are probably on the edge of the TP differential. With tire heating you may go above the differential and throw the flag in the computer. Set the tire pressure you want with the tires cool, and then reset the TP.
