07/30/25 6:39am
The PM2.5 filtration device in a car is typically located within the vehicle's air conditioning system or the front center armrest. Here are the details: 1. Built-in type: Integrated into the car's air conditioning system. Some models with automatic air conditioning don't require manual operation of the PM2.5 filtration device, as the system controls it automatically. However, other models may have air quality switches labeled AQS, ION, or PM2.5 on the air conditioning panel, which the owner can press to activate. 2. External type: Integrated into the front center armrest, with an activation button on the armrest that can be pressed to turn it on. The installation location of the PM2.5 filtration device varies by car model. For specific details, refer to the vehicle's user manual or consult the staff at a 4S dealership.

What is the turning radius of a car?

The turning radius of a car is 8 to 12 meters. Introduction to minimum turning radius: The minimum turning radius refers to the radius of the trajectory circle rolled by the center of the outer steering wheel on the supporting plane when the steering wheel is turned to its limit position and the car turns at the lowest stable speed. Impact of minimum turning radius on driving: To a large extent, it characterizes the car's ability to pass through narrow and curved areas or to bypass insurmountable obstacles. The smaller the turning radius, the better the car's maneuverability. To ensure that the wheels roll purely without sliding during steering, the size of the minimum turning radius is determined by the vehicle's wheelbase. A longer wheelbase results in a larger turning radius, but vehicles with a longer wheelbase have better driving smoothness.

Is the Tire Ruined After Using Tire Sealant?

Using tire sealant will not ruin the tire, but it may cause some corrosion to the wheel rim and tire. Tire sealant is convenient and quick, eliminating the need to remove or replace the spare tire. Simply inject the sealant into the tire through the valve stem to seal the leak. However, tire sealant can affect the tire's dynamic balance. After using it, avoid driving at high speeds, and vehicles with tire pressure monitoring systems (TPMS) should use it sparingly to prevent damage to the TPMS. Tire sealant cannot repair sidewall damage, as a damaged sidewall indicates that the internal cords have broken, posing a safety hazard. In such cases, the tire should be replaced immediately. Due to its corrosive nature, tire sealant should only be used as an emergency solution. Prolonged use may increase future maintenance costs. If time and conditions permit, proper tire repair methods should be applied promptly.

What is the best position to install ETC on a vehicle?

ETC is best installed in the upper middle part of the front windshield for small vehicles such as cars and minivans; for large vehicles like trucks and buses, the lower middle part is optimal. The installation height for ETC should be no less than 1.2 meters and no more than 2.5 meters. Before installing ETC, clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and attach it to the front windshield, pressing firmly for 2 to 3 minutes to remove any air bubbles. Unauthorized removal or movement of the OBU device, a dead battery in the OBU, or the ETC electronic tag falling off or becoming loose may cause the ETC electronic tag to fail. In such cases, you can take the ETC device to the bank where the ETC card was issued or to a highway service center for testing and reactivation.
