You need to locate the power steering fluid reservoir. If your looking at the front on the engine, it will be on the right side of the engine, towards the front. It has a black cap. You will need to lift the plastic engine cover up slightly to be able to remove the dipstick. Remove the dipstick and check the fluid level. You will also add the power steering fluid into this reservoir. The dipstick will have 4 markings on it. Min/Max for 'cold', and Min/Max for 'hot'. Dont overfill the reservoir. And that's it.

One word of caution. Take a look at your lower power steering hose. You can see it from the top of the engine area if you look down along the right side of the radiator. There will be a power steering connected to the radiator, and is very prone to coming off! If this hose looks like it is leaking, or starting to come away from the fitting, take it to your dealer to have it replaced! The hose is warrenty up to 100k miles. Good luck.
