2008 GL450 - Noob Questions

I'm a first-time MB owner ... 2008 GL450 ... couple of things I'd like to find the answers for - 1) My GL450 seems to sit lower to the ground than other GL450s. I've tried to raise the car using the button with the "up arrow in the car", but at a certain speed, the car lowers itself automatically. Do these other GL450 have a different suspension system than mine ? My GL450 seems to sit lower to the ground than even my wife's 4-Runner. 2) How do I keep the air recycler button from going off ? It seems to go off after a certain amount of time and I only notice it due to fumes on the road or other smells. 3) Does anyone find that mixing 89/93 octane gives them better gas mileage ? Thanks

Pictures are helpful here! But if it is under warranty, get it looked at. The lift function lowers at higher speeds. But the car also lowers from standard height at higher speeds. The lift function is only for slower off-roading, not for regular driving. RE: air recycle, I think it is set to time out - you don't want that on very long anyway...in winter your windows will fog up in minutes if it is colder out than in. Only use it when there is a bad smell outside- after a few miles turn it off...you want the fresh filtered air!

Enjoy!
