In winter, the car should use internal air circulation. The function of internal circulation is to promptly and effectively prevent external dust and harmful gases from entering the cabin, providing faster cooling and heating effects. External circulation, on the other hand, supplements fresh air and maintains air circulation between the inside and outside of the vehicle, helping to keep the air inside the cabin clean. The internal air circulation control is located below the front dashboard in the driver's compartment, while the external circulation control is situated below the windshield on the passenger side in the engine compartment. The car's air conditioning system is designed to regulate and control the temperature, humidity, air cleanliness, and airflow within the cabin to an optimal state, providing a comfortable environment for passengers and reducing travel fatigue.

What Are the Reasons for a Manual Transmission Car Being Unable to Shift Gears?

Manual transmission cars may suddenly fail to shift gears due to internal transmission malfunctions, clutch failures, or issues with the gear linkage mechanism connecting to the transmission. The exact cause can only be determined by professional inspection at a 4S shop. Quick solutions for gear-shifting failure are as follows: Start the Engine Before Shifting: If the transmission fluid has not fully lubricated the system, starting the engine and letting it run for a while before shifting can resolve the issue. Repair Damaged Components: If the problem lies within the transmission's internal gear mechanism, such as damaged gears, synchronizers, or shift forks, repairs are necessary. Similarly, if clutch components like the friction disc, pressure plate, or release bearing are damaged, they must be repaired or replaced.
