the factory doesn't set the TPMS like that! what kind of stuff are you smoking? every smart would come with a minimum of 35 miles on the odometer!
the TPMS goes off when a tire goes 10% below the "set value", going above the set value is normal during operation, setting the value when hot guarantees you'll get a display error for sure. the TPMS senses pressure and doesn't give a crap about temperatures.
I didn't say the TPMS was reset by adding air. I simply stated that the light went off when I added air to the tire with low pressure which brings the tire pressure to a manufacturers desired threshold. Our cars have a very simple system. It simply tells us A tire has less or more than what the manufacturer recommends. The Corvettes system tells the owner which tire needs assistance. However all of the arguments I've read here seems to suggest that we can or should reset the system to pressures to levels other than what the manufacturer recommends. I go for following the manufacturers recommendations. Especially while the the car is still under warranty. Ted.
And with that in mind realize that smart has various conflicting pressure recommendations for the car. first off there are different tire and wheel sizes with tires that have different load ratings... than you also have the door sill psi label, the book, and the technicians manual... witch vary in what they recommend! We are trying to get at a general consensus to what is best but must compare apples to apples to do it right.
