Will points be deducted if the car head sweeps the line in the S-curve of Subject 2?

In the S-curve of Subject 2, the car head can sweep the line without point deduction, as long as the wheels do not press the line. Here are the relevant introductions: 1. Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It is the abbreviation of the field driving skill test subjects. The test items for cars C1 and C2 include five compulsory tests: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and curve driving (commonly known as the S-curve). 2. Teaching objectives: Master the basic driving operation essentials and possess the basic ability to control the vehicle; proficiently master the basic methods of field and in-field road driving, possess the ability to reasonably use vehicle control components and correctly control the spatial position of the vehicle movement, and be able to accurately control the vehicle's driving position, speed, and route.

What Causes a Mercedes-Benz to Display Low Tire Pressure Without a Puncture?

Mercedes-Benz displaying low tire pressure without a puncture is likely caused by wheel hub corrosion, tire sealing issues, or slow air leakage. Below is relevant information about automotive tire pressure: 1. Introduction: Tire pressure, strictly speaking, refers to the air pressure inside the tire. Nowadays, many tires are not filled with air. For these tires, tire pressure requirements are more stringent. Tires filled with air are affected by seasonal changes. Moreover, tire pressure is closely related to vehicle performance, such as comfort and load capacity, and also affects tire lifespan. 2. Importance of Tire Pressure: Both excessively high and low tire pressure can shorten tire lifespan. Low pressure increases tire body deformation, leading to cracks on the tire side, flexing movements, excessive heat generation, rubber aging, fatigue in the cord layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear. High pressure causes excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. Impacts can lead to internal cracks and blowouts, while high pressure also accelerates tread wear and reduces puncture resistance.

How to Remove Fog Inside the Car?

Methods for defogging a car are as follows: 1. Air Conditioning Defogging: Turn on the front window defogging mode, set the fan speed to maximum, switch on the A/C button, and then adjust the temperature to the lowest. The fog on the glass will be eliminated shortly. Additionally, some models are equipped with rear window and external rearview mirror electric heating. Simply press the switch to activate it, and the fog will be cleared in about a minute. 2. Air Convection: Opening the windows can increase air convection, reduce the temperature difference between the inside and outside of the car, and weaken the conditions for fog formation. 3. Defogging Agent: When using, just spray it evenly on the glass surface and then wipe it clean with a dry towel. The principle is to use surfactants to leave a protective film on the glass surface, altering the surface tension of water molecules, causing fog droplets to coalesce into larger droplets, thereby not obstructing the view. It is also suitable for other car glass, especially the external rearview mirrors. 4. DIY Defogging Agent with Dish Soap: Mix dish soap and water in a ratio of 1:6, put it in a bottle, and spray and wipe before traveling. The effect is comparable to commercially available defogging agents, though the durability is slightly inferior.

What are the reasons for engine shaking during cold start of Lavida?

Severe shaking during cold start of Lavida may be caused by carbon deposits, weak ignition, low cylinder pressure, or substandard fuel. The following are the reasons and specific solutions for severe shaking during cold start of Lavida: Reasons for severe shaking during cold start of Lavida: Excessive carbon deposits in the intake tract. Mechanical failures such as ignition coils, spark plugs, and fuel injectors. Excessive carbon deposits in the engine. Specific solutions: Excessive carbon deposits in the intake tract need to be cleaned in time. If the fuel quality is substandard, it is recommended to use standard quality fuel. Low oil pressure or cylinder pressure leads to insufficient power. Mechanical failures such as ignition coils, spark plugs, and fuel injectors cause cylinder misfire, and it is recommended to replace ignition coils, spark plugs, and fuel injectors. Excessive carbon deposits in the engine, as the structure of carbon deposits is similar to a sponge. When carbon deposits form on the valves, part of the fuel injected into the cylinder each time will be adsorbed, making the actual mixture entering the cylinder leaner, leading to poor engine performance, difficulties in cold start, unstable idle, poor acceleration, backfire during sudden acceleration, excessive exhaust emissions, increased fuel consumption, and other abnormal phenomena, resulting in engine shaking during cold start.

What is the best engine oil for a Volkswagen Santana?

New Santana models generally recommend using the original 5W-30 synthetic engine oil. It is essential to use engine oil with the correct specifications. Engine oil is a crucial factor affecting engine performance and service life. The vehicle comes factory-filled with specialized high-quality multi-grade viscosity oil, which can be used year-round except in extremely cold climates. Additional information is as follows: Santana: The Santana is one of the most iconic models in Chinese automotive history, embodying Chinese people's emotional connection with cars. The new Santana's front fascia better aligns with Volkswagen's current family design language, featuring thinner chrome grilles that appear more refined and luxurious. The front bumper incorporates a lip-style design, giving it a more youthful appearance. The most significant change at the rear involves the taillights, departing from the current model's conventional rectangular design. The exterior maintains Volkswagen's consistent family styling - not particularly innovative but enduringly appealing. The Santana is equipped with 1.4L and 1.6L naturally aspirated engines, paired with either a 5-speed manual or 6-speed automatic transmission. The suspension configuration remains unchanged, continuing with front MacPherson struts and rear torsion beam setup - a standard arrangement for its class.

What is the fuel consumption of the Arrizo 5?

The fuel consumption of the Arrizo 5 with a 1.5L manual transmission is 7.3 liters per 100 kilometers, while the 1.5L automatic transmission model consumes 8.2 liters per 100 kilometers. The 1.5T model has a fuel consumption of 8.6 liters per 100 kilometers. Below are some details related to fuel consumption: Reasons for increased fuel consumption: Displacement: The engine displacement has a certain impact on the car's fuel consumption, but this effect is a fixed value. Tire pressure: The car's fuel consumption is also directly related to tire pressure. When the tire pressure is too high or too low, the car's fuel consumption will increase. Road conditions: The road conditions on which the car is driven also affect fuel consumption. Methods to reduce fuel consumption: Start slowly, avoid rapid acceleration, shift gears at low RPMs, do not compete with others at red lights, address any dents on the car body, close windows at high speeds to avoid increased resistance, coast in high gears (never coast in neutral as it can lead to steering and brake failure). Fuel consumption can vary significantly based on individual driving habits. Drive safely: do not drive under the influence of alcohol, do not drive while fatigued, do not exceed speed limits or overload, and always wear your seatbelt.
