My wife's ES300 AC is starting to cool less than normal and acting like it needs a charge, hopefully. The car has 85k miles and the AC's never had a charge added to it so it's most likely due for a recharge, everything else about how it operates seems normal and I just replaced the cabin filter.

My question is what pressure does the system operate at and where exactly is the charging port? Any other AC info for the model year would be much appreciated as well.

I searched here for a while but found nothing specific to the model year itself or not enough in one place that it directly answered what I need to know. Then again it's pretty early...
