Pull the floor mats out and see whats rusting there, that goes for any car.

I got a 5 gal bucket of Shell Tellus T22 for my wagon, came in real handy as I did several repairs to the SLS system over a couple of years. The system works well now. The fluid is clean and stays clean.

Hard to imagine how people let that hydraulic fluid go FOREVER without changing it. Mine was black when I got it.
