How do I add freon to my air conditioning for a 2001 Daewoo Lanos?

To add Freon to your 2001 Daewoo Lanos, first ensure the engine is running and the AC is set to the maximum cool setting. Locate the low-pressure service port, which is typically near the AC compressor, and connect the refrigerant can's hose to it. Following the instructions on the refrigerant can, release the refrigerant into the system while monitoring the pressure gauge. Be cautious not to overfill, and always wear safety goggles and gloves for protection.
