What is the function of the vehicle's width indicator light?

Width indicator lights, also known as clearance lights, are primarily used to indicate the presence and approximate width of a vehicle, aiding other vehicles in judging during encounters and overtaking. Below are situations where width indicator lights should be turned on: 1. Driving in foggy conditions: Due to reduced visibility and blurred sight, it is necessary to turn on the width indicator lights along with the fog lights to provide a clear warning to other road users. 2. Rainy weather: They serve as a warning signal to both preceding and following vehicles, helping to minimize potential harm. 3. Night driving: It is mandatory to turn on the clearance lights. Traffic regulations require that rear tail lights and width indicator lights be activated during night driving to alert following vehicles. 4. Dusk: In the absence of streetlights and when vehicle lights are not very bright, it is still essential to turn on the width indicator lights for safety, ensuring other vehicles can see your car.

Does the Air Conditioning Evaporator Need Cleaning?

The air conditioning evaporator needs cleaning. Here is a detailed explanation of why the air conditioning evaporator needs cleaning: 1. The air conditioning evaporator needs cleaning. The air conditioning evaporator is located inside the dashboard. When the air conditioning is turned on, the evaporator undergoes heat exchange, causing a large amount of condensation to form on its surface. At the same time, outdoor air entering the system may carry dust, bacteria, impurities, etc., which can adhere to the surface of the evaporator along with the condensation. 2. Additionally, when the air conditioning evaporator is not in use, it remains in a warm, dark, and humid environment for long periods, making it highly susceptible to the growth of mold and various bacteria. Once mold finds a suitable environment, it can multiply rapidly. Therefore, regular cleaning is necessary, and it is recommended to clean it once every year.

Can a car with modified body kit pass the annual inspection?

If the modified body kit has been registered with the vehicle management office, it can pass the annual inspection. If not registered, it cannot pass the inspection. Changes to the vehicle's body color, model, performance, purpose, and structure, as well as replacement of the frame, body, or engine, all require applying for modification registration with the vehicle management office. Body kits are divided into small and large kits, and modifying them is considered an alteration to the car's appearance, thus requiring registration with the vehicle management office. Otherwise, it is easy to be penalized by traffic police or fail the annual inspection. Vehicles with any of the following conditions must undergo the necessary procedures before they can be inspected: discrepancies between the vehicle's condition and the records in the driving license or archives; damaged, incomplete, or illegible license plates or driving licenses, or self-made license plates; vehicles with modifications, model changes, or technical transformations that have not undergone approval and modification procedures; failure to display the unit name and enlarged license plate number as required; failure to install alarms or indicator lights as required; failure to pay road maintenance fees and insurance as required.

What to Do About Abnormal Noises During Cold Start?

Abnormal noises during cold start may be caused by faulty hydraulic lifters or improper use of engine oil. Below are the specific reasons for abnormal noises during cold start: 1. This could be due to improper use of engine oil, low oil pressure, or wear in the hydraulic lifters themselves, allowing air to enter the hydraulic lifters, resulting in a ticking sound. 2. Wear in the valve rocker arms causing excessive valve clearance, preventing the formation of an oil film in time during cold start. 3. The sound of the carbon canister solenoid valve operating, which is normal. 4. A clicking sound within the first half minute that disappears afterward is usually caused by the expansion of the catalytic converter as it heats up, which is normal. 5. A loud clicking sound during cold start is mostly related to the engine's timing system, such as wear, elongation, or loosening of the timing belt/chain.

Where is the windshield washer fluid?

Location of the windshield washer fluid: Inside the blue cap on the left side under the hood. Below are the functions of the windshield washer fluid: 1. Cleaning performance: Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal. 2. Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface, preventing the formation of fog droplets and ensuring clear visibility through the windshield. 4. Anti-static performance: After cleaning with windshield washer fluid, substances adsorbed on the glass surface eliminate static charges, providing anti-static properties. 5. Lubrication performance: The ethylene glycol in the fluid has high viscosity, offering lubrication to reduce friction between the wiper and the glass, preventing scratches. 6. Anti-corrosion performance: The fluid contains various corrosion inhibitors, ensuring no corrosion on any metal and absolute safety for car paint and rubber.

Can D Gear Be Switched to S Gear?

D gear can be switched to S gear, and there is no need to press the brake pedal during the switch because both D gear and S gear are forward gears. However, after switching to S gear, the car's power will be stronger, and the throttle pedal's sensitivity will also increase. S gear is the car's sport mode (S stands for sport). How to use S gear: 1. To switch to manual mode, you must shift the gear to D gear and then push the gear lever to the right. At this point, the transmission first enters sport mode; 2. Then, you can shift gears by pushing the gear lever forward or backward. In Volkswagen cars, pushing forward is for upshifting, and pushing backward is for downshifting. You can see the current gear from the upper right corner of the central screen on the dashboard; 3. If you want to switch back to automatic mode, simply push the gear lever to the left to the D gear position to complete the switch. At this point, the gear will be controlled by the computer.
