So, me and the FIST are out this morning gathering roots and berries (grocery grabbing) and this curious icon shows up TDC on the tach. It's a cross section of a tire with a ! in the center. WTF! Finished shopping, went home called dealer, went to dealer, had 2" nail in RR tire. In and out in 30 mins. $24. money well spent. For anyone wondering, The TPMS activates at between 3 &4 psi loss of pressure. 800 mi on this car and an effin flat tire? oh well.
