Under hood in front of the driver is a black cap that if unscrewed to allows a store bought can of freon (with 134A connector) to easily snap onto fitting. When A/C is activated the freon is added. Some store bought cans include a gauge which may read around 38 to 41 PSI when the system is nearly full. A special computer chassis scan tool may be needed to first activate the compressor due to a complex temperature/climate design that also sometimes tries to protect the A/C system/compressor from unwanted damage when low oil/freon levels might be detected.
