If you don't know your way around a refrigerant system get a mechanic to charge it for you. The pressures and temperatures in an operating HVAC system aren't trivial and should not be worked on by inexperienced personnel.

Your car uses refrigerant not Freon. Freon is a brand name put out by DuPont. All ac systems use refrigerant often mistakenly called Freon. All of them!!! Check for a decal under the hood or on the compressor for the information you seek. I believe that around 1996 car makers started using R-134A instead of R-12 refrigerant. Hope this helps.
no, losing the manual would not cause the car to use freon.

No, Freon is no longer used in vehicles' cooling system. Should you take your car in for maintenance, the mechanic will use a special vacuum to remove and properly dispose of the Freon. The mechanic will then use R-134, a replacement for Freon.
never use it
Freon is the trade name for R12. Your car contains R134 or R134a which is not Freon.
What is used in vehicles is called Refrigerant, freon is just a brand name used by the DuPont corporation. .......
