Today a strange thing ... while driving in the city a warning was activated on the left display to check tire pressure: It showed me in yellow front right and left pressure 260 (values I believe normal as per booklet indication) rear left pressure 225 (only modestly reduced) and white rear right pressure 230 Puzzled because the values seemed to me substantially normal I stopped off and on and again the signaling continued. To be careful, I stopped at a petrol station and checked the values that were exactly the same (and therefore "normal"). I inflated and deflated to bring the values back to the recommended ones anyway, and I reset the measurement. No warning signal now. Can anyone explain me?
