Why did the Mercedes suddenly shift to M gear?

Will points be deducted for the car hood sweeping the line?

In theory, points are not deducted for the car body sweeping the line in Subject 2. Here is some relevant information: 1. Crossing the line: Crossing the line will definitely result in a 100-point deduction. However, sweeping the line is allowed in right-angle turns and curve driving, as long as the wheels do not run over the road edge line. During the right-angle turn test, try to avoid the car hood sweeping the line, as this can easily lead to failure. 2. Subject 2: The teaching objective of Subject 2 is to require students to master the basic driving operation essentials, possess the basic ability to control the vehicle, proficiently master the basic methods of driving on the site and within the road, have the ability to reasonably use vehicle control components and correctly control the spatial position of the vehicle, and be able to accurately control the vehicle's driving position, speed, and route.

What is the problem when the engine light is on?

The reasons for the engine light being on are as follows: 1. Sensor issues: Sensors include water temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine fault light to illuminate. 2. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also cause the engine fault light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, high oil consumption, reduced power, metal noises, and blue or black smoke from the exhaust pipe. 3. Exhaust issues: Rear oxygen sensor, three-way catalytic converter, exhaust camshaft, and bearing shells. The most common issue is the three-way catalytic converter failure causing the engine fault light to illuminate. Using leaded gasoline, lead or silicon-containing lubricant additives, physical damage to the catalytic converter, and engine fuel supply system failures are some factors that can easily cause three-way catalytic converter failure. 4. Anti-theft system: If the car's electronic anti-theft system malfunctions, or if the anti-theft controller does not match the engine electronic controller, the anti-theft system can also cause the engine to not work properly, along with the engine fault light illuminating.

What are the contents of Subjects 1, 2, 3, and 4 in the driving test?

The contents of Subjects 1, 2, 3, and 4 in the driving test are as follows: 1. Subject 1: Mainly tests basic knowledge such as road traffic safety laws and regulations, traffic signals and their meanings, and traffic rules. With the new driving test regulations, Subject 1 is divided into 12 study hours, and students must complete all study hours before they can schedule the Subject 1 test. 2. Subject 2: Requires practical driving practice, with five mandatory test items: reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curved path. Some regions may have additional items. 3. Subject 3: Road test, usually practiced at a driving school. The instructor teaches students 16 essential skills required for the test, after which they can schedule the test. The main test items include starting, driving straight, shifting gears, changing lanes, pulling over, passing through intersections straight, turning left at intersections, turning right at intersections, crossing pedestrian crossings, passing through school zones, passing through bus stops, meeting other vehicles, overtaking, making U-turns, and driving at night—totaling 16 items. 4. Subject 4: Theoretical knowledge test, building on the basics of Subject 1, it assesses the driver's response methods in critical situations through more practical case studies and animations.

What is the solution for high water temperature during traffic congestion?

When encountering high water temperature during traffic congestion, the solution is to keep the car idling without turning off the engine. Even when arriving home or at the destination, allow the car to idle for 3 to 5 minutes before completely shutting it off. If the temperature remains high after idling for more than 5 minutes, it may indicate a faulty circulation water pump or a blockage in the circulation system pipes, leading to poor circulation. Below is relevant information about high car water temperature: 1. Car cooling systems are divided into two types: water cooling and air cooling (also known as air-cooling). Mid-range and low-end vehicles typically use air cooling, while high-end luxury cars mostly employ water cooling. Water cooling systems can be further categorized into passive water cooling and active electric water pump circulation cooling. Modern vehicles with water cooling systems are generally of the active type. 2. When the car stops, the electric water pump ceases to operate. Once the car starts moving, the electric water pump begins working, facilitating the circulation of cold and hot water to achieve temperature alternation and cooling. Otherwise, the system may experience uneven cooling and heating.
