To be certain, I strongly recommend:
* Checking your owner's manual: This is the best source for the specific location and type of fluid required.
* Looking for a clearly labeled reservoir: The reservoir will likely have a marking indicating "Power Steering Fluid" or a similar designation. It often has a dipstick or minimum/maximum fill lines.
Do not attempt to add fluid without first locating the correct reservoir. Adding fluid to the wrong reservoir can cause serious damage.
