So I just got my 2018 on Friday - today, at 90 miles I got a TPMS module error. All tires are good but the system won't show the PSI of any tire, it just shows as --. I did RTFM and there is a way to reset but it seems pretty involved. Is there a simpler way or can this be done via forscan which is coming Friday, or is this a trip to the dealer? Also, I can't for the life of me figure out how to fold down the backrests of the driver side rear seats. Old age maybe? Passenger side has a strap to pull, no such strap on driver side. TIA.
