What does the snowflake light on the vehicle dashboard indicate?

When the snowflake light illuminates on the vehicle dashboard, it indicates that the outdoor temperature is relatively low, serving as a reminder to the driver that there may be frost on the road. If frost is present on the road surface, tire grip will deteriorate, requiring the driver to exercise caution while driving. The vehicle's onboard computer display can show the external temperature, a function achieved through a temperature sensor fixed on the front bumper. If the snowflake symbol lights up on the dashboard during winter, the driver should reduce speed, maintain a sufficient safe distance from the vehicle ahead, and avoid emergency braking. On frosty roads, emergency braking in such conditions can easily cause the vehicle to skid and lose control.

What does 'setrear' mean on the car's air conditioner?

The 'set-rear' button found in a car's air conditioning system is the rear window defogger button. Here are methods to defog the rear windshield in winter: 1. Open windows for convection: Crack open the side windows slightly to allow air flow between inside and outside the car, reducing temperature differences and gradually eliminating fog; 2. Use the air conditioning system: Simply select the appropriate setting to direct the AC airflow for defogging; 3. Apply professional defogging spray: Spray the defogger onto the inner surface of the car window, then wipe it clean. This not only removes dirt but also forms a protective film to prevent moisture condensation and fog formation on the glass.

What does BSM mean on a car?

BSM stands for Blind Spot Monitoring, a feature designed to prevent collisions or scrapes caused by unseen vehicles when changing lanes during driving. The benefits of BSM are as follows: 1. Reducing lane-changing safety hazards: The blind spot monitoring system effectively addresses blind spot issues during lane changes. This system uses radar sensors hidden on both sides of the rear bumper to monitor the area approximately 20 meters behind the vehicle in real time. If a vehicle or obstacle is detected within the driver's blind spot, it immediately alerts the receiver installed on the edge of the rearview mirror, reducing the risk of collisions during lane changes. 2. Minimizing judgment uncertainty: The blind spot monitoring system helps reduce uncertainty in judgment. Some less experienced drivers may have poor spatial awareness while driving. The blind spot monitoring system provides a clear understanding of the distance between vehicles, enhancing overall safety and reducing the frequency of traffic accidents.

What is the Difference Between Shock Absorbers and Suspension?

Shock absorbers and suspension differ in their types: shock absorbers are a component within the suspension system; a car's suspension system consists of springs and shock absorbers between the body and the tires, supporting the entire vehicle body and improving ride comfort. Since different cars use different suspension systems, the driving experience varies. The suspension system integrates multiple forces, determining the car's stability, comfort, and safety during driving, making it a crucial part of the vehicle. Car suspension systems are divided into non-independent and independent suspensions. Independent suspension offers better tire contact performance, significantly enhancing ride comfort and handling stability, with the left and right tires able to move freely.
