When I filled mine I found the location in the user manual. Also a tip if yours is leaking try lucas stop leak brand. I took my car into the shop and they told me I needed a whole new power steering rack for around 800 dollars. I said screw it i will just fill it up when I need to. I found the stop leak fluid and over time (3 months or so) the leaking has totally stopped. The best part was the bottle only cost $20.00.
