hello everybody. i recently purchased a 2008 g6 gt 4 dr. so far i love the car. i think that the 3.5l has more power than my 98 firebird with the 3.8. oh well thats not wut im here for. yesterday i light came on the dash and the radio told me to check tire pressure. it said the left front tire had only 22psi. after puttin air in the tire, it still says it has 22psi and the left rear now says 60psi. how do i reset the tire pressur moniter???
