Re: tire pressure monitore system light

on my 2008, this is what i had to do. set the parking break. press and hold the lock and the unlock on the fob. the DIC will display something like "relearn tire pressure". let air out of the left front tire until the lights flash or the horn toots . can't remember which. takes about eight seconds.
then do the same on the right front, right rear, and left rear in that order. after the fourth wheel, the horn toots twice. then you can fill them back up to where they are supossed to be.
