Which is on, off or on in a car?

Can the car still run if the air conditioning belt is broken?

The air conditioning belt only drives the air conditioning compressor, so if it breaks, it will not affect the normal operation of the car. Below is relevant information about the car air conditioning system: 1. Introduction to Car Air Conditioning: The car air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. It is used to regulate the temperature and humidity inside the car, providing a comfortable environment for the driver. 2. Working Principle: When the compressor is running, it sucks in low-temperature and low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature and high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser and liquefies, turning into a liquid. When the liquid refrigerant flows through the throttle device, its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature and low-pressure liquid refrigerant absorbs heat from the car's interior air passing through the evaporator and evaporates, turning into a gas. The gas is then sucked back into the compressor for the next cycle.

Which line should not be crossed during reverse parking?

During reverse parking, none of the lines should be crossed. Here are the relevant details: 1. Reverse parking: This involves maneuvering the vehicle correctly into the garage from both sides during movement. Start from point A and reverse into garage B, then park properly. Move forward to the return area C and stop. Reverse from the return area into garage B and stop again. Finally, return from garage B to point A to complete the test. 2. Test items: For small vehicle licenses C1 and C2, the test includes five mandatory items: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-curves). 3. Reverse parking evaluation criteria: The vehicle body must not cross the red line at any point during the process, otherwise you will hear "Vehicle body crossed the line, test failed, please exit the vehicle" or "Vehicle body crossed the line, test failed, please drive the vehicle back to the starting point"; During reversing, you must not stop midway when exiting the garage; After parking, pause briefly before exiting. After completing the test, shift to neutral, exit the vehicle, and leave the test area. Always fasten your seatbelt.

Introduction to the gear function buttons of the Tiguan L

The gear function buttons of the Tiguan L include P, N, R, and D/S. Below is a detailed introduction to each: 1. D: This is the drive gear. Follow the prompts to press the brake, hold the side button on the gear lever, and push the lever downward. 2. S: This is the sport gear, the most powerful gear. The shifting operation is the same as for the D gear. To disengage the S gear, simply pull the gear lever back again (no need to press the brake at this time). 3. N: This is the neutral gear. Use your thumb to press the side button and push the gear lever forward. 4. R: This is the reverse gear. Move the gear lever to the position marked with the letter R. 5. P: This is the parking gear. Press and hold the "P" button on the gear lever. 6. Manual mode: Shift the gear to "D" and then move the gear lever to the right in this position. Move the lever up to shift up and down to shift down.

What is the reason for no cooling at idle but normal operation when driving?

Check if the air conditioning system is malfunctioning. Here is relevant information: 1. Reasons for air conditioning not cooling: Lack of refrigerant, car air conditioning needs to be refilled with refrigerant every 2~3 years. Refrigerant loss is usually due to leakage. If the car air conditioning does not cool, but starts cooling after refilling the refrigerant, consider whether there is a lack of refrigerant. Damage to the air conditioning flap, a relatively common issue is damage to the air conditioning flap motor. If there is a problem with the flap motor, it is relatively more troublesome. The flap motor is generally located in the middle of the dashboard, serving as the main switch for the air conditioning vents. Even if the air conditioning can cool, cold air can only come out through gaps, significantly affecting the cooling effect. 2. Hazards of running air conditioning at idle: When idling with the air conditioning on, instead of focusing on the economic cost caused by fuel consumption, more attention should be paid to the damage to the car and the increased later costs. When the engine runs at low speed and idle for a long time, the piston valves are more prone to carbon deposits. Excessive carbon deposits will directly affect fuel economy and also impact the performance and even the lifespan of the engine.

Why does the AC automatically turn on when defrosting the front windshield?

The reason why the AC automatically turns on when defrosting the front windshield may be related to using warm air for defogging. Reasons for the AC automatically turning on: The AC refers to the air conditioning compressor, while the car's warm air is not provided by the compressor. Therefore, the AC does not operate when using warm air. In winter, when defogging with warm air, if the front windshield defogging function is activated simultaneously, the car's system will automatically engage the compressor. Some vehicle systems even have a memory function—if the warm air and front windshield defogging were used together previously, the system will remember this setting and automatically activate the compressor the next time warm air is turned on. Principle behind the AC automatically turning on: Window fogging occurs due to high humidity inside the car, where moisture in the air condenses on the windows when it meets cold surfaces. The car's warm air comes from the engine's heater core, and the air heated by the heater core tends to be warm and humid. To quickly defog the interior, dry air is needed. When the AC compressor operates, it has a dehumidifying effect—air cooled by the compressor becomes dry, and after being heated by the heater core, the air delivered into the cabin becomes both dry and warm. Blowing this dry, warm air onto the front windshield achieves better defogging results.

What are the car brands?

In terms of brands, cars can be divided into domestic cars, joint venture cars, and imported cars. BYD, Chery, and Hongqi are domestic cars. Volkswagen and Audi under FAW Group, and Peugeot and Honda under Dongfeng Motor Group are joint venture cars. BMW X3 and British Infiniti are imported cars. Japanese brands mainly include: Honda (Acura), Toyota (Lexus), Nissan (Infiniti), Mitsubishi, Suzuki, Mazda, etc. German brands include: Mercedes-Benz (Maybach and AMG divisions), BMW (Rolls-Royce and M divisions), and Volkswagen (Bentley, Lamborghini, Bugatti, Porsche, Audi, Skoda, SEAT, etc.). American brands mainly include: General Motors (Chevrolet, Buick, Cadillac, Pontiac, Corvette, etc.), Ford (Lincoln, Mercury, Mustang, etc.), and Chrysler (Dodge, JEEP brands). Domestic brands mainly include: BYD, Chery (Riich, Rely), Geely, Hafei, Great Wall, Hongqi, Zhonghua, Lifan, JAC, FAW, Besturn, Fengshen, Leopaard, Hawtai, Changan, Fenghua, Roewe, MG, Haima, Maple, etc.
