What are your A/C symptoms? If your gas is not low you might do more harm than good by adding R134a. I would run the built-in climate control diagnostics and look at the value of #7 aka refrigerant pressure before adding any. Just to be on the safe side because there might be another reason your system is not working properly. Plus if that is low, you probably have a leak somewhere so you should also inject some dye to locate it.
