The power steering pump is on the back of the engine on the passenger side. I'm pointing at it'* location.
If you lean over the back of the engine you will see the cap.
Reach in back and remove the cap and check your level. If your low you will need to add some.
Only use power steering fluid. You will need to use a clean funnel. If you have a long neck funnel this will be easier.
Add only a little fluid as this is not a very large reservoir. Remove funnel and check level again. If still low, add more until your between the lines.
