The four ways are fore, aft, seat recline back and up...There is no up or down or tilt to the seat bottom...this is pure cheapness on the part of GM.outlaw said:I have driven 4 SLT-2's and they all have the 4-way power passenger seat. The first time my wife sat in the passenger seat she said that it felt like she was going to slide out of it. This is one of the primary reasons that I have not purchased an Acadia yet. There's an old saying "If momma ain't happy, ain't nobody happy!". I have looked at the specs for the Buick Enclave and the passenger seat is only 4-way power. The Buick is supposed to be an upscale version of the Lamda chassis, but the seating is no different than Saturn or GMC. I think GM should reconsider their thinking on the passenger seat.
