Should You Use Internal or External Air Circulation When Running the Car AC in Summer?

Choosing between internal and external air circulation when running the car AC depends on specific circumstances. Here are the key considerations: External Circulation Mode: This mode uses the fan to draw outside air into the car, meaning the air passage between the exterior and interior remains open. The air blown by the fan comes from outside, and even with the fan off, airflow is still drawn into the car while driving, replenishing fresh air inside. Sometimes, you may feel airflow even when the fan is off—this occurs because external circulation is enabled. In urban traffic jams, the car may fill with exhaust fumes due to external circulation drawing in surrounding vehicle emissions. Internal Circulation Mode: This mode closes the airflow passage between the inside and outside of the car. Without the fan, there is no airflow circulation, and when the fan is on, the airflow is drawn solely from inside the car, creating an internal air loop. Internal circulation primarily blocks external dust and harmful gases from entering, such as when driving through smoke, dust, areas with strong odors, or dense traffic, preventing harmful exhaust from preceding vehicles. Another benefit is maintaining cabin temperature.

How often does a new car need an annual inspection?

New cars are exempt from inspection for the first 6 years. Below are the relevant regulations for vehicle annual inspections: Elimination of environmental protection label: China's traffic authorities have issued new regulations stating that as long as the vehicle passes the annual inspection, the environmental protection label no longer needs to be displayed. Elimination of compulsory insurance label: Currently being piloted in Beijing, vehicles in Beijing can stop displaying the compulsory insurance label and switch to electronic policies. Inspection exemption period: Non-commercial vehicles such as passenger cars are exempt from inspection for 6 years, but every 2 years, the owner must submit the compulsory insurance policy and vehicle and vessel tax certificate to the vehicle management office, then directly apply for the inspection compliance label from the traffic police department.

What does max mean?

MAX on a car refers to the maximum value. Below are the meanings of MAX in different locations: Car air conditioning: If it's in the car air conditioning system, MAX indicates the upper limit of the cooling mode. Engine oil dipstick: If it's on the engine oil dipstick, MAX represents the upper limit of the fluid level. When adding engine oil, make sure the fluid level does not exceed the MAX mark. Car fluid reservoirs: MAX on car fluid reservoirs indicates the upper limit of the fluid level in each reservoir. The fluid level should not exceed the horizontal line corresponding to MAX, and it should be between the upper and lower limits. Additional information: Vehicles all have MAX markings, but they are distributed in different locations. Some are on the fluid containers in the engine compartment, while others are on the car interior. In daily use, pay attention to the MAX mark when adding windshield washer fluid or power steering fluid. Reaching this mark indicates that the addition is complete.

Why is there no air coming out from the windshield defroster vent?

The angle adjustment button for the air vents on the vehicle's air conditioning control panel is malfunctioning, preventing the air flow from being redirected; the pipelines of the vehicle's heating system are clogged and need to be cleaned at an auto detailing or car wash shop. Below is relevant information: Air vent adjustment: There are five adjustment modes. The first is the foot mode, the second is the foot and face mode. The third is the face mode. The fourth is the windshield and foot mode. The fifth is the independent air flow mode, which can be switched via buttons or knobs according to different usage environments. Notes: The air conditioning system must have the vehicle's AC switch turned on for operation, whereas the heating system does not require this. When using the air conditioning, the vehicle's internal circulation should be activated, switching to external circulation every half hour. For the heating system, external circulation can be used without the need for frequent switching to internal circulation.
