Great advice, but before you do that make sure your reservoir is full to about an inch from the top on the standard set up when the slides are in. I haven't seen what a new rig with level-up looks like, but on my add on level-up the fluid level is about 2/3 of the way full on the much larger reservoir. I marked it with a magic marker when they installed it and I asked if that was as full as it should be.
