How do you add freon to a 1996 Toyota Tercel?

To add freon to a 1996 Toyota Tercel, first ensure the vehicle is turned off and parked on a level surface. Locate the low-pressure service port, which is typically found on the larger of the two AC lines. Attach the refrigerant can to the port, start the engine, and turn on the AC to the maximum setting. Slowly release the refrigerant into the system while monitoring the pressure gauge until it reaches the recommended level. Always follow safety precautions and consider consulting a professional if unsure.
