What is the car's air conditioning heating symbol?

The heating switch symbol is generally displayed as a "thermometer". The blue pattern above indicates cold air, while the red pattern indicates warm air. To increase the temperature inside the car, turn on the air conditioning and rotate the knob to the red area. Here are some precautions for using car heating: 1. No need to activate the compressor: The car heating system used in winter is a non-independent residual heat heating system, which utilizes heat from the radiator, exhaust pipe, etc., to warm the air, which is then blown into the car by the fan. Therefore, the compressor does not need to be activated when using the heating. 2. Avoid turning on the heating immediately: Since the water temperature in the radiator is still low when the vehicle is first started, warm air can only be blown out after the water temperature rises. Moreover, turning on the heating at this time not only blows cold air but also increases the engine's burden, causing the water temperature to rise more slowly. Therefore, let the vehicle run for a while until the water temperature gauge reaches half of the normal operating temperature before using the heating. After turning on the heating, use the external circulation first to refresh the air inside the car, then switch to internal circulation after a few minutes. 3. Turning on the heating does not increase fuel consumption: The heating relies on heat exchange from the radiator, exhaust pipe, etc. Apart from the fan, it hardly uses any other equipment, so it does not cause an increase in fuel consumption.

How to Judge the Distance Between Front, Rear, Left, and Right While Driving?

Here are the specific methods for judging the distance between front, rear, left, and right while driving: 1. Front distance judgment method: When you see the upper edge of the rear bumper of the car in front, the distance between your car and the car in front is 1m; when you see the lower edge of the rear bumper of the car in front, the distance is 2m; when you see the lower edge of the rear tire of the car in front, the distance is 3m. 2. Rear distance judgment method: When the rear car fills the right rearview mirror, the distance between the front and rear cars should be 3 meters; but when the rear car fills the left rearview mirror, the actual distance is only 1 meter. When the rear car occupies 2/3 of the left rearview mirror, the actual distance is only 3 meters. When the rear car fills 1/2 of the left rearview mirror, the distance to the rear car is 5 meters. 3. Left and right distance judgment method: When the junction point between the left lane divider line and the front of the car is about 20cm away from the left A-pillar, the left wheel should have or is about to touch the line. When the right lane white line coincides with the center of the hood, the car is basically on the line.

What are the differences between Subject 4 and Subject 1?

The main differences between Subject 1 and Subject 4 include: the number of test questions, question types, content distribution, and focus areas. The information is based on the "Regulations on the Application and Use of Motor Vehicle Driving Licenses". Number of test questions: The most obvious difference between Subject 1 and Subject 4 is the number of test questions. Subject 1 has 100 questions, while Subject 4 only has 50 questions. In Subject 1, the test will automatically submit if more than 10 questions are answered incorrectly, whereas in Subject 4, the test will submit automatically if more than 6 questions are answered incorrectly. Question types: Subject 1 consists of 100 questions, each worth 1 point, with a total test duration of 45 minutes. The question types include true/false and single-choice questions, with a full score of 100. Subject 4 consists of 50 questions, each worth 2 points, with a test duration of 45 minutes. The questions are mainly presented in the form of case studies, images, animations, etc., and include true/false, single-choice, and multiple-choice questions, with a full score of 100. Focus areas: Subject 1 primarily tests basic knowledge of road driving, while Subject 4 focuses on safe and civilized driving practices. In simple terms, Subject 1 is about how to drive, and Subject 4 is about how to drive safely. Although the difference is just two words ("safe"), the focus is entirely different. Content distribution: Subject 1 test content breakdown: 20% on driving license and motor vehicle regulations; 25% on road traffic conditions and rules; 25% on traffic violations and penalties; 10% on traffic accident handling regulations; 10% on basic vehicle knowledge; and 10% on local regulations. Subject 4 test content breakdown: 20% on safe driving practices; 18% on civilized driving practices; 8% on comprehensive application of traffic signals in real scenarios; 16% on safe driving in adverse weather and complex road conditions; 12% on emergency avoidance practices; 6% on typical accident case analysis; 10% on accident rescue and hazardous chemical handling; and 10% on local test questions. There is no limit to the number of attempts for Subject 1 and Subject 4 in the driving test. If a candidate fails, they can reschedule the test. Each scheduled test allows two attempts. If both attempts are unsuccessful, the candidate must retake the test until they pass. Both Subject 1 and Subject 4 are theoretical exams and are part of the motor vehicle driving license assessment. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the examination on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the examination on field driving skills. Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in official terms (i.e., the Ministry of Public Security's Order No. 123), there is no such term as Subject 4.

Does the Audi Q7 Burn Engine Oil?

Audi Q7 does experience engine oil burning. Here are the reasons why the Audi Q7 burns engine oil: 1. To increase power, the engine cylinder walls have a honeycomb pattern designed to store more oil for enhanced lubrication. However, this honeycomb oil storage pattern has slightly weaker sealing, causing a small amount of oil to leak into the combustion chamber. 2. Audi, along with other German car brands, has engines with higher compression ratios compared to other car manufacturers. This results in higher engine operating temperatures, especially in turbocharged engines. If the engine oil has poor high-temperature stability, it can evaporate, accelerating oil consumption. 3. Congested road conditions in China combined with low-quality fuel lead to excessive carbon deposits. Additionally, German engines inherently have larger gaps between pistons and cylinder walls, and while the piston rings have good toughness, their tension is weaker. If the engine oil's cleaning ability is insufficient, carbon deposits on the pistons cannot be cleaned in time, increasing cylinder wall wear and reducing sealing performance, making oil burning inevitable.

What to Do When a Scooter Motorcycle Won't Start After Getting Wet?

Check after shutting down. Here are the relevant details: 1. Specific situation: If the motorcycle stalls and won't start after passing through water, stop trying to start it immediately. Inspect whether the air filter, carburetor, or exhaust pipe has taken in water. Clean the air filter and carburetor thoroughly—once cleared of water, the motorcycle should start. Additionally, check if water has entered the engine. If the engine is waterlogged, the oil must be replaced, and you must ensure all water is drained before restarting. 2. Special cases: If there is no water in the air filter, carburetor, or engine but the motorcycle still won't start, the issue might be moisture in the ignition system components such as the high-voltage cap, ignition coil, ignition unit, or magneto coil, or their wiring connectors. In this case, no repairs are needed—simply let the motorcycle dry completely, and it should start again.
