Will Car Windshield Washer Fluid Freeze in Winter and What Are Its Functions?

Whether car windshield washer fluid freezes in winter depends on two scenarios: 1. Antifreeze washer fluid will not freeze. Antifreeze washer fluid ensures it remains unfrozen even when the external temperature drops below -20°C. It is an all-weather windshield cleaning solution containing antifreeze and cleaning components, capable of preventing freezing in winter and directly dissolving frost. 2. Ordinary washer fluid may freeze in winter. Windshield washer fluid primarily serves the following three functions: (1) Cleaning performance: Windshield cleaner is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing properties, thereby achieving cleaning and stain removal effects. (2) Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost. (3) Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with unobstructed visibility.

How to Maintain Tires?

Tire maintenance involves the following four methods. 1. Perform wheel alignment and tire rotation: Conduct wheel alignment and tire rotation every 10,000 kilometers. 2. Regularly check tire pressure: Tire maintenance also includes periodic pressure checks. Tires exceeding the specified pressure will significantly reduce their lifespan, while tires below the specified pressure can lead to poor braking performance, difficulty or heaviness in steering, and also shorten tire life. 3. Always pay attention to the wear indicators on tires: The tire wear indicator is located in the main drainage grooves of the tire and is a trapezoidal rubber protrusion. When the tread wears down to the level of the wear indicator, the tire must be replaced. During the rainy season, to prevent the vehicle from slipping on wet roads, the tread depth must be maintained above 3mm. 4. Regularly inspect tire condition: Frequently check tires to promptly identify issues such as bulges, cracks, cuts, punctures, valve rubber aging, and abnormal tire wear. Pay special attention to inspecting the wear on the tire tread and edges.

What are the contents of the new policy on the transfer of new energy vehicles?

There are differences in government policies in some regions, and there are corresponding restrictions on the transfer time of new energy vehicles. For example, in Shanghai, new energy vehicle license plates must be used for at least 3 years from the date of activation, and can only be transferred or re-registered after 3 years. Precautions for the transfer of new energy vehicles: In most regions, the transfer time and related procedures for new energy vehicles are the same as those for blue-plate fuel vehicles, meaning that the transfer can be processed as long as the vehicle ownership is established. However, it should be noted that blue-plate fuel vehicles have license plates that follow the person, while new energy vehicle license plates follow the vehicle. Tax exemption scope for the transfer of new energy vehicles: For the transfer of used new energy vehicles, no additional purchase tax is required. According to relevant regulations, tax-exempt vehicles remain within the tax-exempt scope when transferred. The transferee must re-declare the tax exemption to the relevant tax authorities within 60 days from the date of purchase or acquisition of the vehicle.

How to Use the Automatic Transmission D+?

Use the automatic transmission "D+" in the following situations: (1) When going downhill, you can shift up to D2 or D3 using "D+". Downhill driving requires the engine's braking effect, and gears 2 or 3 can meet the power demand without needing the high torque of gear 1. (2) Sometimes on uphill sections with sufficient power, "D+" can be used to upshift to prevent power wastage and damage to the engine and transmission. (3) When the ETC does not accurately interpret the driver's operational intent, manual upshifts can also be performed using "D+". Below is an introduction to the automatic transmission "D+": The "D+" and "D-" in automatic transmissions refer to the manual mode. Generally, when the gear is in D, shifting the gear lever left or right switches to manual mode. In manual mode, the driver can use "D+" and "D-" to shift gears up or down. Pushing toward "D+" increases the gear by one, and pushing toward "D-" decreases the gear by one.

How often should a car be inspected after 15 years?

It requires inspection every six months, twice a year. Below are details about the annual inspection: National regulations: Motor vehicles must undergo regular inspections, including emissions testing, exterior appearance, lights, brakes, chassis, etc., and must have no traffic violation records to receive an inspection compliance sticker. All inspection dates are based on the registration date listed on the vehicle's license. From the date of registration, motor vehicles must undergo safety technical inspections within the following timeframes, commonly referred to as "annual inspection" or "annual review." Regular inspections: For small and micro non-operational passenger vehicles: within the first 6 years, inspection every 2 years; after 6 years, inspection once a year; after 15 years, inspection every 6 months. For operational passenger vehicles: within the first 5 years, inspection once a year; after 5 years, inspection every 6 months. For trucks and large/medium non-operational passenger vehicles: within the first 10 years, inspection once a year; after 10 years, inspection every 6 months. Imported vehicles follow the same rules as other vehicle types and can undergo regular inspections at any testing facility.

Where is the Reverse Radar Switch?

Depending on the button layout of different car models, it is generally located on the button panel on the left side of the steering wheel or the central control panel. After turning on the reverse radar switch and shifting the gear lever into reverse, the reverse radar will start working. Reverse radar is a safety auxiliary device for parking or reversing a car. It can inform the driver of the surrounding obstacles through sound or more intuitive display, eliminating the troubles caused by the driver's peering around when parking, reversing, and starting the vehicle, and helping the driver to eliminate blind spots and blurred vision. When reversing, the reverse radar uses the principle of ultrasound. The probe installed on the rear bumper sends ultrasonic waves to hit obstacles and reflects these waves, calculating the actual distance between the car body and the obstacles, and then prompts the driver, making parking or reversing easier and safer. The reverse radar mainly consists of ultrasonic sensors, a controller, and a display or buzzer. Ultrasonic sensor: Its main function is to send and receive ultrasonic signals, then input the signals into the main unit, and display them through display equipment. Controller: It processes the signals and calculates the distance and direction between the car body and the obstacles. Display or buzzer: When the sensor detects that the car's distance from the obstacle reaches a dangerous distance, the system will issue an alarm through the display and buzzer to remind the driver. Millimeter-wave reverse radar is a type of reverse radar. It detects the presence and distance of obstacles through millimeter-wave radar probes, transmits them to the central controller, and achieves alarm and prompt functions. The millimeter-wave reverse radar adopts a multi-channel serial port control method with a central controller, which can achieve all-around detection and warning around the vehicle. Because it adopts high-frequency millimeter-wave detection, it overcomes the shortcomings of ultrasound, such as short working distance and unstable effects in harsh environments. It has good application effects in special vehicles, engineering vehicles, port and dock operation vehicles, cranes, and other large machinery industries. The advantages include stable detection, long detection distance, and no influence from rain, snow, or fog.
