Reasons for the yellow light on the car dashboard: 1. Sensor issues, including water temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, which will trigger the engine fault light; 2. Maintenance issues, the yellow light on the dashboard is due to prolonged use without maintenance, and it is advisable to visit a 4S shop for servicing; 3. Dirty throttle body, poor performance of a certain cylinder, requiring inspection and replacement of spark plugs and cylinder wires, oxygen sensor, and checking for three-way catalytic converter faults, etc.

How to Deal with High Beams Blinding You?

Here are methods to handle being blinded by other vehicles' high beams: 1. Shift your gaze away from the opposing vehicle's lights. Human eyes are highly sensitive to light, especially during nighttime driving when visibility is already poor. When a vehicle suddenly approaches with high beams on, your eyes can easily be dazzled, causing temporary blindness and making it difficult to see the road ahead. Therefore, when facing high beams, briefly shield your eyes with your hand or shift your gaze away. 2. Slow down or stop. While shifting your gaze, it's also necessary to reduce speed or even come to a complete stop, allowing the oncoming vehicle to pass first. After all, completely avoiding high beams by shielding your eyes or looking away isn't always possible. If blinded by high beams, your vision may be filled with light beams, making it hard to see anything around you. For safety, slow down or stop to let the oncoming vehicle pass. 3. Flash your high beams three times consecutively to alert the opposing driver. Sometimes, flashing your high beams three times in a row can serve as a reminder for the other driver to turn off their high beams. 4. Use an anti-glare rearview mirror. Generally, anti-glare rearview mirrors are designed to counteract high beams from vehicles behind you. If a following vehicle has its high beams on, activating the anti-glare feature can provide some safety assurance. Without this feature, high beams from behind can be extremely glaring. Although not as bright as those from oncoming vehicles, they still pose significant danger.

What is the difference between 5w30 and 5w40?

5w30 and 5w40 differ in viscosity: 5w30 oil has a kinematic viscosity between 10 and 12, while 5w40 oil has a kinematic viscosity between 13 and 16. The 'W' stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating a lower usable environmental temperature and better engine protection during cold starts. The number after the 'W' represents the oil's kinematic viscosity at 100 degrees Celsius. A higher number indicates higher viscosity, better protection at high temperatures, and can also be understood as representing the oil's stability at high temperatures (i.e., the likelihood of thinning). A larger number means better high-temperature stability performance.

Which Cars Come with HUD Head-Up Display?

BMW 5 Series Li, Peugeot 3008, Peugeot 508, Audi A6, Audi A7, Lexus GS, and Land Rover Vision Concept are among the models equipped with HUD head-up displays. Due to the high cost of this system, it was previously only available in a few luxury cars priced in the million-dollar range. Here is more information about HUD head-up displays: 1. HUD stands for Head-Up-Display, which translates to a head-up display in Chinese. It utilizes augmented reality technology to project vehicle or road condition information onto the display (primarily the windshield). Different types of HUDs project varying data such as speed, time, and engine status. Most HUDs use innovative phosphors to project information onto the windshield via lasers. Some HUDs also integrate transparent screens to display critical information. 2. Installing an HUD head-up display in a car not only showcases a cool sense of technology but, more importantly, ensures safe and stable driving by allowing the driver to focus more on observing the road and driving, thereby enhancing travel safety on every trip.

Why did the dash cam suddenly stop lighting up?

Reasons why the dash cam suddenly stops lighting up: 1. The dash cam is out of power: If the dash cam is used continuously for a long time, it will reduce the battery life, and the screen will naturally go dark when the battery is depleted; 2. The dash cam's own screen saver: Similar to a computer screen, some dash cams will automatically turn off the screen to save power if not operated for a long time; 3. The dash cam has crashed: If the internal system of the dash cam becomes disordered, it can easily cause a crash; 4. The dash cam is damaged: If the dash cam is damaged due to a traffic accident or human factors, it is necessary to ask a professional to repair or replace it with a new one.
