Reset TPMS

Reset TPMS
Do I need to do anything to reset the Tire Pressure Monitoring System after I check pressure and add air to the tires? In BMW 328, I had to reset it, but I read the manual of G37 and it seems that nothing needs to be done. Just want to make sure I am reading it right.

So you have to reset the TPMS in the 328 every time you add air to the tires? Wow, that sounds like a PITA. I'm guessing/hoping that means you can perform that operation directly somewhere on the dashboard with the bmw?
With the G you have to either take it to the dealership or buy a $100+ tool to plug into the ODB to reset the TPMS. But like hi-lo said ^^^ you shouldn't need to do it unless you are replace the sensors or wheels. Otherwise that would certainly be a drag!

Actually, the reset was just a few quick, simple flips on the stalk attached to the steering column, sort of like resetting the trip computer on the G37. It takes about 5 seconds to perform.
The way in which the TPMS works, as I understand it and at least on BMW, is that it monitors the relative difference in tire pressures of all 4 tires. If one of tires is, say, 4 PSI lower than the others, a warning signal will come on (but it does not tell you which tire). After checking/adding the air, the "difference" is to be reset to zero.

Just had a flat tire fixed last week. After the tire was patched and put back on the car. The TPMS reset(turned off) itself. I asked the dealer if he had to reset it and he said no. It went off by itself. This is how I would expect it to work. To have to manually reset is silly, but I could see a Manufacturer trying to find a way to force you to bring it in and charge you $20 to reset. Thank goodness Infiniti chose to do the right thing. The monitor should be checking every few seconds and should certainly be able to turn off the light when every thing is within spec.

Yeah what he said. The car measures the pressure while tires are rotating and you're doing at least 15MPH - any less and the system does not work. Add air, drive it above 15MPH for a little bit, and the TPMS warning will disappear.

In the newer G cars, is it correct that the TPMS will trip if the pressure in any tire drops below 30psi? I think the dealer mentioned that, but I have yet to confirm that in the manual.
