Engine hood reference point, wiper rivet reference point, and rearview mirror reference point. Here are the detailed explanations: Engine hood reference point: When entering a left right-angle turn, first align the vehicle body and drive close to the right side of the road, ensuring that the right 1/3 of the engine hood aligns with the right edge line of the road. Maintain this alignment by making slight steering adjustments, keeping the right side of the vehicle approximately 30cm from the road edge line. Wiper rivet reference point: When entering a left right-angle turn and aligning the vehicle body to drive close to the right side, position the left wiper rivet to align with the right edge line of the road. Maintain this position while driving, keeping the vehicle body approximately 30cm from the road edge line. Rearview mirror reference point: For a left right-angle turn, observe the right rearview mirror. When driving close to the right side, ensure that the door handle in the mirror image just touches the right edge line of the road, keeping the right side of the vehicle approximately 30cm from the edge line. For a right right-angle turn, due to different observation distances and angles, when the mirror image shows the vehicle body or rear wheel is about two fingers' width from the roadside line, the left side of the vehicle should be approximately 30cm from the roadside line.

When I was learning to drive, the trick for the 30cm right-angle turn was to find reference points and control the speed slowly. The instructor taught me to adjust the seat and mirrors first to ensure a clear view. When turning, align with the roadside line, and when the right door handle coincides with the line, quickly turn the steering wheel to full lock. At the same time, check the right mirror to keep the wheel about 30cm from the line. If it's too close, make slight adjustments; if too far, correct early. The whole process should be done at a slow speed, maintaining idle speed to prevent the car from rushing too fast and losing control. Practice in an open area with marked lines, repeating it over a dozen times until you master it. The key is accurate alignment, quick steering, and staying calm. This technique is not only useful for the test but also practical for roadside parking to avoid scratches.

How to Check the Engine Oil Level?

Car engine oil level is primarily checked using the oil dipstick. Here is a detailed explanation of how to check the engine oil: 1. Park the car on level ground: Regardless of the shape of the engine oil pan, the position of the oil dipstick remains constant, meaning it measures the oil level at a fixed location. The car must be parked on a flat surface as specified to obtain an accurate measurement. 2. Using the oil dipstick: Always insert the oil dipstick all the way in. The oil level should be between the upper and lower marks on the dipstick to ensure proper operation of the engine and related components. A few minutes after turning off the engine, although most of the oil has drained back into the oil pan, oil splashed by the crankshaft may still cling to the dipstick, potentially causing misreading. 3. Identify the correct dipstick: In some car models, there are two dipsticks in the engine compartment—one for engine oil and another for transmission fluid. Make sure to identify which one is the actual engine oil dipstick.

What Are the Disadvantages of Pure Electric Vehicles?

Pure electric vehicles have the following disadvantages: 1. Charging Difficulty: In the context of lagging charging infrastructure construction in China, charging is a major challenge for electric vehicles. The lack of public charging piles severely impacts the mobility of electric vehicles. 2. Short Driving Range: Limited by battery capacity, most pure electric vehicles currently have a driving range of only 100-200 kilometers. Although experts repeatedly claim that 90% of people drive less than 50 kilometers daily, Chinese consumers have higher range requirements than Americans. This is because few Chinese families own more than one car, whereas Americans can use one pure electric vehicle for commuting and a traditional car for travel. 3. Slow Charging: Currently, most charging piles are slow chargers, taking 5-8 hours to fully charge a vehicle. While overnight charging during rest periods is possible, the drawback of slow charging becomes evident in case of emergencies. 4. After-Sales Service Needs Improvement: Although the structure of electric vehicles is simpler, the powertrain differs significantly from traditional cars, leading to some repair challenges. The first issue is the shortage of skilled technicians. Most technicians today can repair traditional cars but lack knowledge in electrical systems. Attempting to repair electric vehicles without proper expertise may not only damage the vehicle but also pose certain risks. The second issue is the scarcity of spare parts. Due to the low production and ownership of electric vehicles, spare parts are limited and expensive.

What to Do When a Motorcycle Won't Start After Long-Term Storage?

There are four main methods to address a motorcycle's failure to start after prolonged storage. Below is a detailed introduction to these four solutions: 1. Replace the gasoline: Under normal circumstances, gasoline that remains unused for more than six months will degrade in quality. It may also develop gum deposits, which can cause engine gumming and make starting difficult. Therefore, when a motorcycle fails to start, it is advisable to replace the old gasoline with fresh fuel. 2. Manually rotate the crankshaft quickly: When a motorcycle is left unused for an extended period, the engine loses lubrication from the oil, resulting in low cylinder pressure and insufficient lubrication for the crankshaft components. In such cases, manual intervention by quickly rotating the crankshaft can help. 3. Charge the battery: A motorcycle battery left unused for several months is typically in a discharged state. Promptly charging the battery should resolve the issue. 4. Replace the spark plug: If a motorcycle remains unused for a long time, the spark plug is likely to become damp. A damp spark plug can significantly hinder ignition. In this situation, the spark plug should be inspected first, and if found faulty, it should be replaced with a new one.

Must the Vehicle Be Registered Where It Is Purchased?

Newly purchased vehicles can be registered in a different location. According to national regulations, as long as the vehicle meets the standards and satisfies the local registration requirements, it can be licensed, regardless of where it was purchased. Additionally, there is no significant difference between registering a vehicle in a different location versus locally. Documents required for registering a vehicle purchased elsewhere: Vehicle certification of conformity; Purchase invoice; Proof of compulsory traffic insurance; Proof of vehicle purchase tax; ID card; Residence permit. Specific process for registering a vehicle purchased elsewhere: Purchase the vehicle at a local 4S store. Prepare a temporary license plate for inspection by traffic police on the way back. Be sure to note the validity period of the temporary license plate. Contact the local insurance company to purchase the corresponding compulsory traffic insurance and vehicle damage insurance by sending the vehicle frame number of the purchased vehicle before registration. Complete the registration procedures at the local vehicle management office.

What Are Some Clever Tricks for Dealing with Scratches on Black Cars?

For minor scratches on black cars that have not exposed the primer, you can use a touch-up pen, apply toothpaste, or wax the area. Below are specific details about these scratch treatment methods: 1. Touch-up pen: Use a touch-up pen to color the scratch. While this method may not be as effective as professional treatment at a body shop, it can help prevent rust from spreading or worsening, especially for small or inconspicuous scratches. 2. Apply toothpaste: When you notice new minor scratches on the car's body, gently apply toothpaste in a circular motion over the scratched area. Reapply after rain or washing the car. This can generally reduce the visibility of the scratch and provide a simple barrier to prevent rust, at least in the short term. 3. Waxing: Very light scratches can be removed with regular maintenance wax. For deeper scratches, use a wax commonly known as "rubbing compound," which has stronger polishing properties. Before waxing, make sure to wash the car thoroughly to remove any dust or debris. Be careful not to use too much wax—just enough to cover the damaged area.

What Causes the Abnormal Noise When Braking in D Gear While Stationary?

The main reasons for abnormal noise when braking in D gear while stationary are: 1. Excessive viscosity of transmission oil: Lack of lubrication from the oil leads to increased wear. 2. Low efficiency of the release fork shaft: Small clutch travel causes the axial clearance of the cross shaft to increase. 3. Clutch oil: The performance of clutch oil decreases due to temperature effects. Here are some additional details: 1. Introduction: The D gear is the most widely used forward gear in automatic transmission vehicles. 2. Purpose: Its main function is to enable the transmission to automatically select the appropriate gear in real-time through the transmission's computer and matching mechanical structure while the vehicle is moving forward, thereby eliminating the need for manual shifting and greatly freeing the driver's hands and feet, improving driving convenience, ease, and comfort. The driver only needs to control the accelerator pedal, brake pedal, and steering wheel, allowing better focus on the driving view and road conditions.
