Got this air inflator button and a valve in the trunk of my 00 SSEI and am not sure what it is for. Just not sure if this is "air shocks" or what exactly does it do and what is its purpose.

There'* supposed to be a kit with it. You can air up bike tires, you own car'* tires, basket balls and that sort of thing. If you have it, It means you have the air suspension.

what will happen if you push the air button and the compressor runs. Will it inflate the suspension? will the compressor stop by itself? how much air is needed for a good overall ride? how do you measure the current air pressure in the suspension?

Your air suspension is called ELC. Electronic Level Control. There'* a sensor under your car that keeps the system level automatically. If you want to adjust the 'stance' of the car, you have to adjust the sensor. Procedure is in Techinfo, but most cars are set correctly.

If you want to OVER inflate your rear end to preven weight transfer at the dragstrip, simply pull the connector on the valve, push ON for the inflator, wait for the car to rise, then remove the ELC fuse to prevent the suspension from venting back to the normal ride height.

Will'* directions are not for the 2K'*, there'* no fuse to pull for us.
For the track just pop off the arm and set it at the highest postion, when you start the car the suspension will rise to the top.

please decribe the arm are you're talking about.

what would you do to set the suspension to optimal level road/track or sporty driving.

Having air shocks on my last car that did not benefit from an on-board compressor/sensor, I can say that pumpung up the car can make the back end too stiff or bouncy.

Maybe not everyone would agree, but I think you'll find the better way to adjust that for daily driving would be with spring and/or strut upgrades.

I do think there is a fuse, and that it is in the panel under the back seat. But I could be mistaken.

Forgot to add that the kit you can get through your dealer'* parts department, or even online, has a nice air hose with an inflation guage, and several tips for rafts or balls and such. It also comes with an emergency light, gloves, and a couple of other things. It costs a lot though, and you could probably put together a similar or better set of tools for much less. I don't think it came with jumper cables though, which I thought was odd.
