I have always done this by emptying the PAS bottle from the top using a syringe, replenishing with fresh ATF, starting the engine and turning the steering wheel from lock to lock.

Then repeat the operation 2-3 times. Check PAS fluid level again at the end.

Alternatively you could undo the lower hose on the steering rack and let the fluid out this way, but unless you have access to lift or ramps this can be messy.

The thing about PAS fluid is that - unlike brake fluid - there is no need to bleed - i.e. it's a straight forward swap, a bit like changing engine oil.
