I have attached a picture of where to fill up, sorry this is the best one I could find, the port is located a little off the screen but it should give you the general location.
1. Turn the car on, turn the knob to MAX AC
2. Then connect the can and gauge to the port I have shown you. You have to unscrew the cap before of course.
3. Make sure that the gauge is not above 100 PSI. IF it is that means that the compressor is not working properly or at all.
4. Normally it should cycle between 20-25 to 40-50 PSI.
5. So if it is below 20 PSI you can fill up.
DO NOT fill up just yet, after you have connected the can to the line, unscrew it just a little as to purge the hose with refrigerant in order not to allow any air/moisture to get in the system. Moisture+Refrigerant = Acid
Then quickly screw it back on. Turn the valve to pierce the can and you are ready to fill up, while all this is happening the car should be kept running and monitoring the gauge is keeping between the ranges above.
