What do 261, 145, and 520 mean in Subject 1?

In Subject 1, 261, 145, and 520 refer to the visibility on highways, the maximum speed of vehicles, and the minimum distance between vehicles in rainy and foggy weather. In each of the three combinations, the first digit represents visibility, the second digit represents the maximum speed of the vehicle, and the third digit represents the minimum distance between vehicles (where 0 indicates the need to find the nearest exit to leave the highway). Related introduction to Subject 1: 1. Exam content: According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the exam content includes theoretical foundations of driving, road safety laws and regulations, local regulations, and other related knowledge. The exam format is computer-based, with 100 questions, and a passing score of 90 or above. 2. Exam question bank: Since July 2015, the Ministry of Public Security has updated the Subject 1 question bank to 1229 questions, while the question bank for large vehicles remains unchanged. The exam question bank is a unified national version, and there is no such thing as local questions.

What are the speed ranges for gear shifting in Subject 3?

Subject 3 gear shifting speed ranges are: shifting from first to second gear should occur at 15 to 20 km/h; shifting from second to third gear should occur at 25 to 30 km/h; shifting from third to fourth gear should occur at 35 to 40 km/h; and shifting from fourth to fifth gear should occur at 45 to 50 km/h. Introduction to Subject 3: 1. Exam content: The road driving skills test for Subject 3 generally includes: vehicle preparation, light simulation test, starting, driving straight, gear shifting operations, lane changing, parking by the roadside, driving straight through intersections, left turns at intersections, right turns at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and nighttime driving. The safe and civilized driving knowledge test generally includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. 2. Exam difficulties: In the Subject 3 test, it is explicitly required that the distance for parking by the roadside should not exceed 30 cm, but this distance is difficult for students to grasp, and many students park too far from the roadside.

Where is the rear window heating button on the Passat Lingyu?

The rear window heating button on the Lingyu is located on the air conditioning panel of the center console, a rectangular button with a wave pattern. Using air conditioning or opening windows to defog: Ventilating the car is a common method to defog, including using the air conditioning and opening windows. Turning on the air conditioning in cold air mode can help balance the temperature and reduce fogging, while using the hot air mode can promote the re-evaporation of moisture on the glass, also helping to defog. Using desiccants to defog: If you frequently encounter fogging inside the car, you can place some desiccants inside to absorb moisture from the air. Keeping the interior environment dry makes it difficult for fog to form and also helps prevent bacterial growth and mold, benefiting the health of the occupants. Using anti-fog spray: Fogging significantly impacts driving safety, so there are specialized anti-fog sprays available on the market. These sprays are very easy to use—simply spray evenly over the glass to prevent fog from forming. However, the effect of anti-fog sprays is limited, usually lasting about a week, so it's best to spray promptly when fog appears.

Can You Still Drive with a Bulging Tire?

You cannot drive with a bulging car tire because prolonged or high-speed driving can cause the tire temperature to rise, which may easily lead to sudden rupture of the bulging area, resulting in a tire blowout. A tire bulge occurs because the inner layer of the tire consists of a fabric ply without steel wires—only nylon cords that prevent the internal gas from bulging outward. When several cords break simultaneously, the damaged area is left with only elastic rubber to support it. Under the pressure of the gas, the rubber expands, forming a bulge. Prolonged or high-speed driving raises the tire temperature, increasing the risk of sudden rupture at the bulging spot, i.e., a blowout. To prevent tire bulges and blowouts, follow these precautions: 1. Drive slowly on poor road conditions: If you drive a regular passenger car, avoid rough roads or drive cautiously in such areas. 2. Avoid uneven force distribution: When parking, do not partially mount curbs or uneven surfaces, as this can cause uneven tire stress. 3. Prevent rim damage: Slow down when crossing speed bumps to avoid rim scratches and tire impact, which may contribute to bulging over time. 4. Regularly check tire pressure: Ensure the tire pressure remains within the normal range to prevent bulging caused by abnormal pressure.

How to Determine When the Car is Fully Parked in Reverse Parking?

Judgment should be based on the car's length and mirrors. Here are the specific methods: 1. Method to determine complete parking: During the reverse parking process, find appropriate reference points from the driver's position and make judgments using the car's rearview mirrors and body. Control the car's direction well. When the car's body is parallel to the parking line, keep the steering wheel steady and continue reversing. From the driver's seat, observe the car's left rearview mirror. When the lower edge of the left rearview mirror just covers the left exit line, you can press the brake pedal. Stopping at this position ensures the car's front and rear distances in the parking space are just right. You can also make appropriate corrections during reversing. Correct operation ensures the car stops steadily. 2. Preparation for reverse parking: Reverse parking is the starting content of driving license subject two. Before reverse parking, first adjust the car seat's front and rear positions, and adjust the backrest to a comfortable angle to ensure the driver can drive the car easily and control the steering wheel. Also, adjust the car's rearview mirrors so that the car body appears in about 1/3 of the mirror. From the main driver's position, the car's body and door handles can be observed through the rearview mirrors. After all adjustments are made, you can proceed with reverse parking.

How to Replace the Wiper Blades on the X-Trail?

Lift the metal wiper arm away from the windshield and maintain it perpendicular to the windshield in a stable position. Then press the tab to release and remove the old wiper blade, separating it from the metal arm. Insert the new wiper blade and gently rotate it until the hook snaps into place to secure it. Below is an introduction about wipers: 1. Wipers, also known as windshield wipers, are devices used to sweep away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. 2. The wiper motor adopts a 3-brush structure for easy speed variation. The intermittent timing is controlled by the intermittent relay, utilizing the motor's return switch contacts and the relay's resistor-capacitor charge-discharge function to make the wiper sweep at a certain cycle. The wiper blade rubber is the tool that directly removes rainwater and dirt from the glass. The blade rubber is pressed against the glass surface by a spring strip, and the lip must match the angle of the glass to achieve the required performance. 3. Generally, there is a wiper control knob on the car's combination switch lever, with three settings: low speed, high speed, and intermittent. The top of the lever is the washer button switch; pressing it sprays washer fluid to clean the windshield in coordination with the wiper. The washer system is a common device in cars today, consisting of a water reservoir, water pump, water delivery pipe, and spray nozzles. The washer fluid is divided into fine jets by the squeezing action of 2 to 4 spray nozzles and directed at the windshield, working with the wiper to clean the windshield.
