What does FRT on a car mean?

FRT on a car should mean front. The automotive air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle compartment. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. The air conditioning system has become one of the indicators of a car's functionality. Below are the functions of a car's air conditioning system: 1. Temperature regulation: This is the primary function of car air conditioning. In summer, the cooling system produces cold air to lower the temperature inside the compartment; in winter, except for large commercial vehicles that use independent combustion heaters for warmth, other vehicles generally utilize the car's residual heat for heating. 2. Humidity regulation: Humidity significantly affects passenger comfort. The humidity inside the compartment should generally be maintained between 30% and 70%. Standard car air conditioning systems do not have the function to regulate humidity; only advanced luxury cars equipped with integrated heating and cooling systems can achieve this through ventilation devices. 3. Airflow regulation: The speed and direction of airflow greatly impact comfort. If the air blows directly, the speed should be limited to a certain range when the temperature is appropriate. The airflow speed can be adjusted based on passengers' living environment, age, health condition, and temperature preferences. 4. Air purification: The quality of air inside the compartment is crucial for ensuring comfort.
After driving for so many years, I know that 'FRT' on a car usually stands for 'Front,' commonly seen on the air conditioning control panel. For example, a button labeled 'FRT' represents the front windshield defogging function. Many older and newer car models are designed this way, especially during winter or rainy days when fogging is frequent. Pressing it automatically switches the vents to blow air onto the front windshield, helping to quickly clear the fog and prevent accidents caused by blurred vision. I often use this feature while driving, particularly in the morning when fog appears—just press it, and the AC switches to the front window mode, with slightly higher temperature and stronger airflow. If you're unfamiliar with these buttons, you might accidentally press others, causing the AC to adjust improperly. In short, understanding these symbols makes driving safer and more convenient. Remember, it’s part of the vehicle’s design to optimize the interior environment.
