What type of fluid is used for the power steering? on 2006 Cadillac DTS

I had noticed my cooler gauge was slightly higher. I checked all of my fluids and I found the fluid level in my power steering low.

The specification states to use GM power steering fluid - part number 89021184.

Your owners manual will list the recommended fluid. Used to be that people used ATF or power steering fluid but check the manual for correct fluid.
