When the rear car occupies one-third of the right rearview mirror area, the distance is approximately 15 meters. When the rear car occupies half of the right rearview mirror, the distance is about 10 meters. If the rear car occupies half of the right rearview mirror, it indicates that the rear car is very close, and turning maneuvers are not advisable at this time. Function of Rearview Mirrors: Rearview mirrors are one of the essential safety components on a motor vehicle, used to observe the rear road conditions during reversing and to monitor the surroundings while driving. For the convenience of the driver, to prevent traffic accidents, and to ensure personal safety, all countries mandate the installation of rearview mirrors on vehicles, and all rearview mirrors must be adjustable in direction. Classification of Rearview Mirrors: There are mainly two types of rearview mirrors on vehicles: one is the flat mirror, which, as the name suggests, has a flat surface similar to typical household mirrors, providing an image of the same size as seen by the naked eye. This type of flat mirror is commonly used as the interior rearview mirror. The other type is the convex mirror, which has a spherical surface with varying radii of curvature. It produces a smaller image than the naked eye but offers a wider field of view, functioning like a camera's "wide-angle lens." This type of convex mirror is commonly used as the exterior rearview mirror and the lower rearview mirror.

Why does the AC light automatically turn on when the heater is on?

It is normal for the AC light to turn on automatically when the heater is activated. This is a common setting in many vehicles, where the compressor starts running as soon as the blower is turned on. If you want to use the heater but the AC light is on, you can press the AC button to turn off the compressor. The compressor does not need to run when using the heater, and its operation will increase fuel consumption. The principles of cooling and heating in a car's air conditioning system are straightforward. When heating, the high-temperature coolant from the engine flows through the heater core, and the air blown by the blower also passes through the heater core, allowing the air conditioning vents to blow warm air. When cooling, the engine drives the compressor to operate. The compressor continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, cooling the evaporator. The cooled evaporator then cools the air blown by the blower, allowing the air conditioning vents to blow cold air.

How to Drive Safely on the Highway?

Highway safe driving requires the following six points: 1. Conduct pre-driving inspections, including checking tire pressure and brakes, to avoid malfunctions during high-speed driving. 2. Maintain sufficient safety distance while driving to prevent emergency braking by the vehicle ahead. 3. Keep a safe distance from large trucks, as they are numerous on highways. Following too closely not only severely obstructs your view but also increases the risk of falling cargo. 4. Immediately apply the brakes to reduce speed upon noticing the brake lights of the vehicle ahead. 5. Do not occupy the emergency lane unless absolutely necessary. If required, promptly activate hazard lights and place a warning sign behind the vehicle. 6. Avoid fatigued driving; if drowsiness occurs, take a break at the nearest service area immediately.
