The functions of car rain guards are: 1. In rainy conditions, they maintain fresh air circulation inside the vehicle to meet human needs; 2. Prevent window fogging that could obstruct the driver's vision and operation, enhancing driving safety; 3. Block side glare and UV rays, reducing interior temperature; 4. Keep rain, snow, and dust out while still allowing air exchange with the outside. Precautions for using car rain guards: 1. Purchase from authorized dealers to ensure quality; 2. Clean the window area thoroughly with a cloth before installation, as excessive dust or debris can weaken the adhesive strength.

The main function of rain guards is to prevent rainwater from directly entering the car during rain, especially when opening the windows for ventilation. They also effectively block sunlight, reducing excessive heat inside the car. I find them particularly practical for daily commutes, such as driving to and from work in the rain—cracking the windows slightly improves airflow without getting the interior wet. Additionally, they prevent rainwater from blurring the view outside the window, reducing safety hazards. In high summer temperatures, they can also indirectly save on air conditioning costs. Some designs even help reduce wind noise at high speeds, making driving quieter and more comfortable. Overall, this accessory is quite thoughtful, easy to install (usually a DIY job), and enhances both convenience and safety. It's definitely worth having a set in your car.

The rain visor may seem like a small accessory, but it serves a big purpose. When driving, it extends outside the car window, effectively blocking rainwater from splashing onto the seats or dashboard. What I appreciate most is its ability to prevent rain from obstructing my view while driving on highways during rainy days, indirectly enhancing safety. Additionally, it allows for fresh air circulation by keeping the windows slightly open without letting rain in, significantly improving air quality inside the car. In terms of sunshade, it slows down the rapid temperature rise inside the car when parked in summer, greatly enhancing comfort. As a bonus, it might even extend the lifespan of the interior by preventing rainwater corrosion. For smokers or parents with children, this accessory is nothing short of a lifesaver.

The most basic function of rain guards is to block rain and shade the sun. Installed on the upper edge of car windows, they prevent raindrops from entering while allowing ventilation during rainy weather, keeping the driver's view clear. Personally, I feel they enhance driving comfort—for example, enabling window ventilation without getting wet during long trips, which reduces fatigue. In hot weather, they also provide sun protection and help cool the interior. Another related benefit is reducing the chance of window fogging, as improved ventilation prevents moisture buildup. Overall, this small accessory is simple yet highly effective, suitable for all types of vehicles.

What to Do When the Engine Yellow Light Appears on the Car Dashboard?

The engine yellow light appearing on the car dashboard indicates an engine malfunction that requires immediate repair. The engine fault light illuminates due to sensor issues, which include the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, oxygen sensor, etc. When these sensors are damaged or have poor contact, the ECU cannot accurately obtain engine data, causing the fault light to illuminate. Engines have specific maintenance cycles, and failure to perform timely maintenance can increase the engine's load. Combined with poor driving habits, this can lead to engine malfunctions.

What does it mean when the engine yellow light is displayed on the dashboard?

Reasons for the engine yellow light appearing on the dashboard: 1. When the car's power is turned on, the vehicle performs a self-check. During this time, not only the engine yellow light but also other fault lights will illuminate and then turn off together. 2. If the engine fault yellow light remains on after starting the car, this is the ECU alerting that there is a fault in the engine. For example, sensors such as water temperature, crankshaft position, air flow, intake temperature, and oxygen sensors, when damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine fault light to illuminate.

What does a faucet symbol on the car dashboard indicate?

When a faucet symbol appears on the car dashboard, it indicates the engine malfunction indicator light. If the engine malfunction light stays on continuously, you should stop the vehicle and call for professional assistance. However, in many cases, a continuously illuminated engine malfunction light does not signify a major issue—it could be a false alarm or a minor problem that doesn't affect driving. In such situations, you can safely drive to a repair facility for troubleshooting. The engine malfunction light is triggered by the ECU (Engine Control Unit), commonly referred to as the car's computer. The ECU controls all electronic components of the engine, including the electronic throttle, fuel injectors, alternator, fuel injection pump, catalytic converter, and more, covering systems such as intake, exhaust, fuel delivery, ignition, and timing.

Why is the battery light on the car dashboard illuminated?

Car dashboard battery light is illuminated to alert the driver to promptly check for vehicle faults. If the battery light is on before starting the vehicle, it indicates that the alternator is not generating electricity and the battery is not charging. After the car starts, when the alternator begins generating electricity and the battery is in a charging state, the battery indicator light will automatically turn off. If the battery indicator light remains on after the vehicle starts, it means the alternator is not generating electricity. Reasons for the dashboard battery light being illuminated include: 1. Battery failure: The solution is to use a multimeter to test the battery voltage. If the voltage is low, charge it to restore; if the battery is faulty, replace it. 2. Loose or oxidized battery terminals: Poor contact can also cause the battery light to illuminate. The solution is to clean and tighten the battery connections.

What does it mean when the blue water temperature light on the car dashboard is on?

When the blue water temperature light on the car dashboard is illuminated, it indicates that the water temperature is currently too low. If the light is blue right after starting the car, this is normal, and it will turn off once the car warms up. However, if the light remains blue continuously, it suggests a problem that requires inspection at a repair shop. The blue water temperature light signifies low water temperature; it will turn off after driving for a while or idling for some time as the temperature rises. Conversely, a red light indicates high water temperature, and the car should not be driven further. The blue or green water temperature indicator light on the dashboard is a normal low-temperature warning, indicating that the engine has just started and is in the warm-up phase. During this time, avoid aggressive driving to prevent severe engine wear due to low water temperature. The light will turn off once the water temperature reaches the optimal operating range for the engine.

What does the engine symbol on the car dashboard mean?

The engine symbol on the car dashboard is an engine fault warning light, indicating that there is a fault in the engine. This light illuminates when the engine's electronic control system, sensors, or wiring malfunction, alerting the driver to promptly visit a 4S shop to address the issue. Modern cars generally do not experience serious mechanical problems, but sensors and electronic systems are the most prone to failure. It is advisable to avoid using low-quality fuel during regular use, as poor-quality fuel can also trigger the engine fault light. The engine is equipped with a knock sensor; when knocking is detected, the ECU will take corrective measures. If the vehicle requires high-octane gasoline but the owner consistently uses low-octane fuel, the engine fault light will illuminate. The car dashboard is a device that reflects the working status of various vehicle systems, commonly including indicators such as the fuel level light, washer fluid light, electronic throttle light, and front/rear fog light indicators.
