There are several threads on here that tell you how to do it properly. Use google as well there are several threads with pictures. Its typically a 2 person job, and you will need the OEM fluid from the Dealer to flush it properly.

 

Have a friend get under the car near the t case bleed screw for the ACD system. Insert your key and turn the car to the on position. Press your gas pedal to the floor till you hear the ACD system pump kick on and turn off. Repeat this process until you have satisfied your bleeding desires. Use a good ATF for the reservoir fill.

I think the poster was referring to the ATF red fluid you have to use to bleed the ACD with.
