Air suspension?? How do I know if I have one?

[ehaser]

I've got a button on my dash that lifts the rear of my truck about 2 inches but the front doesn't lift? Does that mean that I have the air suspension?? Unfortunately my truck did not come with an instruction manual. I think it has the adventure package but i'm not sure. How can I find out?

Yes, air suspension is only in the rear

Yep you have the air suspension! You should have the trailer levelling button too. The air bags in the rear aren't too difficult to see if you get under the rear axle.

So it's the same set up as my 08 Yukon Denali? Is it primarily used for towing in order to keep the "rear end" level?? What other purpose does it serve? My Denali's is automatic. I can usually hear it kick on when I have the whole family in the car. I think it makes my SUT look odd when the rear end is up in the air.. I received a lot of slack for purchasing my SUT by extended family. We went out to dinner in the city last night and I brougt a few of them along. Everyone comment on the ride quality. They all expected it to ride really rough and nothing like a luxury truck. I love it...

Basically used for increased ride quality, levelling under load conditions and when off road you can use the extended ride height feature for a greater departure angle

Do all H2's with the rear air have the "aux tire inflator"? I can' find one on mine. I'd feel alot better if I had one after removing my rear tire rack.
