What Lights to Use When Turning at Night?

When turning at an intersection, turn on the turn signal and use the low beam. When passing through sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signal control, alternately use the high and low beams to alert others. Here is some related information about hazard warning lights: 1. Definition and Usage: The hazard warning light is also known as the emergency flasher. The button for the hazard warning light is located in the center of the dashboard, marked with a red triangle. Pressing it will cause all four turn signals to flash simultaneously. 2. Usage Scenarios: Hazard warning lights are the highest-level warning lights, so many people instinctively turn them on in heavy fog. However, this practice is prohibited in some countries because it can make it difficult for following vehicles to determine the direction of the vehicle ahead. It is especially important to note that you should never change lanes with hazard lights on. Avoid changing lanes in foggy conditions whenever possible. If lane changing is necessary, turn off the hazard lights and use the turn signal instead.

Can Antifreeze Be Used as Windshield Washer Fluid?

Antifreeze cannot be used as windshield washer fluid, as it lacks the cleaning properties of washer fluid. Antifreeze and windshield washer fluid are entirely different and should not be mixed. Precautions for using antifreeze: Always use the same brand of antifreeze. Different brands may have varying formulations, and mixing them could cause chemical reactions between additives, rendering them ineffective. The role of antifreeze: Antifreeze is a coolant with special additives, primarily used in liquid-cooled engine cooling systems. It provides excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion year-round. The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances. Antifreeze replacement cycle: For vehicles that operate for long periods, such as taxis, high-quality antifreeze should generally be replaced annually. Vehicles with shorter operation times can replace it every two years or every 30,000 kilometers. To prevent excessive foaming, which reduces the heat exchange efficiency between antifreeze and engine components, ensure the product is within its validity period when adding it. Long-life antifreeze can last up to three years. If suspended particles, sediment, or discoloration are observed in the antifreeze, replace it promptly and clean the system.

Is It Serious If a Car Is Flooded Up to the Carpet Level?

A car being flooded up to the carpet level is quite serious. Here is a detailed explanation of car water ingress situations: 1. Minor water ingress: A small amount of rainwater splashing in will not affect the car's wiring system or mechanical system, as the wiring system is protected by covers. Simply clean and dry the wet items. 2. Severe water ingress: Rainwater can enter the cabin, potentially causing malfunctions in electronic devices or rusting some components inside the cabin. Additionally, since the front passenger seat is close to the dashboard, electronic devices are likely to get wet when water enters the car. Even if the electronic devices are not damaged, the front passenger seat, floor mats, and other interior components may still get soaked.

What Causes the Inner Door Handle to Fail in Opening the Door?

If the inner door handle fails to open the door, it may be due to a damaged lock mechanism or a broken linkage cable. It is recommended to have it inspected and repaired at a service shop. The inner door handle is typically mounted on the door trim panel, while the outer handle is fixed on the door outer panel, facilitating the opening and closing of the door. Both handles are equipped with mechanisms to release the door lock, allowing the door to open when the lock is disengaged. A malfunctioning inner handle can lead to unnecessary inconveniences. Below is an introduction to car doors: 1. Car Door: A car door provides access for the driver and passengers and serves to isolate external disturbances, offering some protection against side impacts and safeguarding occupants. The aesthetic appeal of a car is also influenced by the design of its doors. 2. Door Quality: The quality of a car door is primarily reflected in its crash protection, sealing performance, and ease of opening and closing, among other functional indicators. Crash protection is particularly crucial because side collisions occur with minimal buffer distance, posing a high risk of injury to occupants. A high-quality door typically contains at least two crash beams, which are relatively heavy. Therefore, while better doors tend to be heavier, it is not accurate to assume that the heavier the door, the better its quality.

How to Distinguish Between Different Car Body Types?

Vehicles are divided into engine compartment, passenger compartment, and trunk based on their spatial structure. A sedan (three-box car) refers to a vehicle where these three parts are completely separated and independent from each other. Here is a relevant introduction to car body types: 1. Based on compartments: Single-compartment car, hatchback (two-box car), two-and-a-half-box car, sedan (three-box car). 2. Based on doors: Two-door (also called three-door), four-door (also called five-door). 3. Based on vehicle categories: Subcompact car, microcar, compact car, midsize car, full-size car, luxury car, sedan, CDV (Car Derived Van), MPV (Multi-Purpose Vehicle), SUV (Sport Utility Vehicle), etc. 4. Based on body structure: Unibody (monocoque) and body-on-frame. 5. Based on roof type: Hardtop convertible, soft-top convertible, semi-convertible.

What Causes the Sound Like Pumping Air When Braking?

Here are two possible reasons for the sound resembling air pumping when braking: 1. Movement of the master cylinder core and booster pump: The sound occurs during the braking process but stops when the pedal is fully depressed and held down. This is likely the sound of the master cylinder core and booster pump moving, which is generally not a major issue, depending on whether the replaced brake fluid meets the required standards. 2. Leakage in the booster: The sound continues when the pedal is fully depressed and held down, indicating a leak in the booster, which requires repair or replacement of the booster assembly. Below is some related information about the braking system: 1. Principle of the braking system: The braking system uses vacuum-assisted braking, and the booster pump produces intake and exhaust sounds during operation. 2. Function of the braking system: The brake pedal, as the name suggests, is the pedal that limits power, i.e., the pedal for the foot brake (service brake), used for deceleration and stopping. The braking system is one of the five major control components in driving, thus it is used very frequently.
