I've got the same problem, looked in the manual, found the pic showing the reset button, went outside, and there is no button. Our car does not appear to have any of the reset or blinker noise adjustment knobs pictured in the owner's manual. Are they tucked up under the dash rather than standing in plain sight like the manual shows? Help, please.
Did you get an answer on how to find the reset? I still can't find it.
No. The car is going to the dealer tomorrow (still under warranty). They seem to think there may be a sensor failure, because the system was supposed to reset automatically--aster they had me pull the spare and check the air in it (which can't be done with a standard air gauge without taking the tire out of the well). I have contorted myself into a pretzel looking for that reset button. All I found was a sheet metal blank held in place with a screw where the manual said the reset button was. Doing away with the reset may have been a running change. At any rate, the G$^&% thing is still showing a tire low. At least it's not ringing at me.
I just got the same answer - They are saying that is is a sensor problem that must be dealer serviced. I have the convertible. No spare tire at all.
Will let you know when it gets resolved. The car runs so much better with regular radial tires and no run flats. Just need to shoot the alarm.
