What is the function of the yellow light on the rearview mirror?

The small yellow light on the rearview mirror is part of the Blind Spot Monitoring Warning System. Its function is to illuminate when there is a moving obstacle approaching or moving away from the side or rear of the vehicle, serving as a reminder. It alerts the driver to the presence of vehicles or pedestrians in the blind spot, prompting caution when changing lanes or turning to avoid traffic accidents caused by visual blind spots. Factors determining the field of view of the rearview mirror: The distance between the eyes and the rearview mirror, the effective area of the rearview mirror, the radius of curvature of the rearview mirror, the tilt angle of the rearview mirror relative to the line of sight, and the distance between the rearview mirror and the ground. Solutions for left and right rearview mirror blind spots: Install wide-angle rearview mirrors. These mirrors are attached to the edges of the left and right rearview mirrors and can significantly reduce blind spots, essentially meeting all needs for overtaking and lane changes. It is also important to practice using peripheral vision to observe approaching vehicles or pedestrians. This ensures safe overtaking and lane changes, preventing accidents.

Are Rearview Mirror Rain Guards Actually Useful?

Rain guards, as a traditional method of rain protection, do have certain effectiveness, especially during light rain. However, their performance is not ideal during heavy rain. Here is some information about maintaining visibility in rearview mirrors during rainy conditions: Using soap or detergent as a cleaning agent: Cleaning agents contain surfactants, whose hydrophobic groups physically drive water outward, preventing water droplet formation. The operation is quite simple: apply or spray soapy water or detergent solution onto the rearview mirror and let it dry. While this method is very convenient, its effectiveness is short-lived, typically lasting only about 2 days. Applying wax to rearview mirrors: When water comes into contact with a waxed surface, the internal cohesion of water becomes greater than its adhesion, preventing droplet formation - a principle similar to that of lotus leaves. Although waxing is also simple, wax is highly sensitive to temperature changes. If not applied properly, it may actually impair visibility, which is why this method isn't widely used.

Is it normal for a Corolla to run 400 kilometers on a full tank of gas?

"It is normal for a Corolla to run 400 kilometers on a full tank of gas. Here is some information about the Toyota Corolla: Exterior: The sharp momentum emanating from the high-brightness four-round crystal diamond headlights at the front gives the COROLLA Corolla a poised-for-action appearance. The chrome-plated horizontal front grille smoothly spreads the lines to the left and right sides and extends backward along the headlights, outlining a dynamic front body. Discontinuation time: In fact, FAW Toyota had planned to discontinue the Corolla as early as 2007, but due to strong recognition from domestic consumers, FAW Toyota delayed the discontinuation by ten years. After the Corolla was discontinued, the Corolla using the new TNGA platform became its replacement.

What does Variable Cylinder Engine mean?

Variable Cylinder Engine, abbreviated as VCM, is a Variable Cylinder Management technology developed by Honda. By deactivating specific cylinders, it allows a 3.5L-V6 engine to operate with 3, 4, or 6 cylinders, enabling the engine displacement to vary between 1.75-3.5L, thereby significantly saving fuel. Below are the details: 1. Applicable Vehicles: Variable Cylinder Technology is generally suitable for multi-cylinder, large-displacement models, such as V6, V8, V12 engines. 2. Cylinder Switching: Under conditions requiring high power output, such as vehicle start-up, acceleration, or climbing, the engine will engage all 6 cylinders. During medium-speed cruising and low engine load conditions, the system will operate only one cylinder bank, i.e., three cylinders. During moderate acceleration, high-speed cruising, and gentle slope driving, the engine will operate with 4 cylinders.

Why is the right rear fog light not working?

The reason why the right rear fog light is not working is that some vehicles are equipped with only one fog light, and the right side is actually a reverse light. If it is confirmed to be a dual rear fog light setup, the issue may be a burnt-out bulb or a circuit break on the other side. Below is relevant information about fog lights: Introduction: In addition to the front high beams, low beams, headlights, and parking lights, and the rear running lights and brake lights, most vehicles also have a set of inconspicuous fog lights at the rear. Rear fog lights are red signal lights installed at the tail of the vehicle, designed to be easily noticed by traffic participants behind in low-visibility conditions such as fog, rain, or dust. They emit a stronger light intensity than tail lights. Classification: Fog lights are divided into front fog lights and rear fog lights. Front fog lights are typically bright yellow, while rear fog lights are red. The symbols for front and rear fog lights differ slightly—the front fog light symbol has downward light beams, while the rear fog light symbol has parallel beams. These symbols are usually located on the vehicle's dashboard. Due to their high brightness and strong penetration, fog lights do not produce diffuse reflection in foggy conditions, making them effective in preventing accidents when used correctly. In foggy weather, front and rear fog lights are usually used together.
