How to Turn on the External Circulation?

What are the reasons why a Tiida won't start?

The reasons why a Tiida won't start are as follows: 1. Severe carbon buildup inside the vehicle's engine: This makes it difficult to start the vehicle and causes idle shaking. 2. Malfunction in the vehicle's ignition system: It's necessary to check the vehicle's spark plugs and high-voltage wires. Abnormal operation of the ignition system can lead to this situation, resulting in idle shaking or difficulty starting the vehicle. 3. Unstable fuel pressure in the vehicle's fuel system: The fuel pump cannot properly supply fuel to the vehicle, leading to poor fuel atomization in the engine or failure to open the fuel injectors, causing cylinder misfire shaking or failure to start. 4. Fault caused by insufficient engine cylinder pressure: Due to time-related issues, the vehicle's engine has exceeded its service life and can no longer continue to operate, leading to intermittent idle shaking. In such cases, immediate workshop maintenance is required. Regular inspections, maintenance, and repairs are essential to prolong the vehicle's service life.

Can the Seat Belt Be Opened When a Car Falls into Water?

Automobiles have a certain degree of watertight performance. Once a car is submerged in water, the driver's first action should be to immediately unbuckle the seat belt and then quickly unlock the electronic central locking system to prevent the door circuits from malfunctioning. Below is a relevant introduction to car seat belts: Function: Car seat belts are safety devices designed to restrain occupants during a collision and prevent secondary impacts with the steering wheel, dashboard, etc., or to avoid injuries or fatalities caused by being ejected from the vehicle during a collision. Car seat belts, also known as safety harnesses, are a type of occupant restraint system. Working Principle: The retractor's function is to store the webbing and lock it when pulled out, making it the most complex mechanical component in the seat belt system. Inside the retractor is a ratchet mechanism. Under normal circumstances, occupants can pull the webbing freely and evenly while seated. However, when the webbing is continuously pulled out and suddenly stops or when the vehicle encounters an emergency, the ratchet mechanism engages to automatically lock the webbing, preventing it from being pulled out further.

What is the actual fuel consumption of the Crosstour 2.4?

The official combined fuel consumption of the Crosstour 2.4 is 9.1L/100KM, while the actual fuel consumption is around 10.2L/100KM. The actual fuel consumption is related to many factors: in addition to human operation factors, it is also related to the thermal efficiency of the engine and the resistance the car experiences. The core factors affecting the car's fuel consumption are as follows: 1. Thermal efficiency of the engine: From a purely technical perspective, direct injection is a very good technology that greatly improves fuel combustion efficiency, but it has higher requirements for the engine's fuel supply system and cylinder materials. 2. Resistance the car experiences: Gradient resistance: When a car is driving on a slope, the component of its gravity along the road direction is manifested as the gradient resistance. Obviously, it is mainly related to the weight of the car. The heavier the car and the steeper the slope, the greater the force that needs to be overcome, and the higher the car's fuel consumption. Acceleration resistance: When a car accelerates, there is an inertial force, which is the acceleration resistance. According to the momentum theorem, the greater the mass of the car and the greater the acceleration, the greater the resistance.

Why is the rear wheel of the motorcycle not turning?

Possible reasons include the rear brake being stuck, a broken drive belt, or damaged gearbox gears. Below is relevant information about motorcycles: History of Chinese Motorcycles: In August 1951, China officially began independently trial-producing and manufacturing motorcycles. At that time, the Beijing Automobile Manufacturing and Fitting Plant No. 6 of the Chinese People's Liberation Army completed the trial production of five heavy-duty military motorcycles, which were named Jinggangshan brand by the Central Military Commission. This motorcycle could reach a maximum speed of 110 kilometers per hour. By 1953, the annual production of Jinggangshan brand two-wheeled motorcycles exceeded 1,000 units. The advent of the Jinggangshan brand motorcycle marked the dawn of a new era in China's motorcycle industry. Sports Motorcycles: Sports motorcycles, also known as sports bikes, are primarily designed for leisure and holiday use. They serve as both an entertaining means of transportation and a recreational tool for experiencing the joys of life. The category of sports motorcycles is quite extensive, including the super sports motorcycles and touring motorcycles described below, both of which possess the functionalities of sports motorcycles and thus can also be classified as such.

Where is the Bluetooth in the Volkswagen Lavida low-end model?

There is a Bluetooth button on the multimedia console of the Volkswagen Lavida. Turn on both the mobile phone Bluetooth and the car Bluetooth, and make sure they are in a discoverable state; on the mobile phone's Bluetooth interface, click "Search for Devices." The mobile phone can then search for the car Bluetooth; select the car Bluetooth displayed on the mobile phone and click on the car Bluetooth settings to pair; if the pairing code is entered correctly, "Connected" will be displayed on the car Bluetooth shortly after; in the car Bluetooth settings interface, select the "Auto Connect" function to enable automatic connection in the future. Relevant information about car Bluetooth is as follows: 1. Function: After the Bluetooth function is successfully matched, you can use the mobile phone to play audio files or answer calls, which is very convenient. While driving, it ensures driving safety. After the car system and Bluetooth system are connected, you can directly make calls on the car system, using it in a hands-free manner. 2. Auto Connect: Once the mobile phone and car system are connected, they will automatically connect the next time they are used, provided the mobile phone's Bluetooth system is turned on. This eliminates the need for frequent connections, saving time and bringing convenience to vehicle use. However, when using Bluetooth calls, privacy should be taken into consideration.

What Causes a Car Air Conditioner to Stop Cooling but Work Again After Restarting?

There is an issue with the air conditioner's receiver-drier. The car air conditioning system includes a receiver-drier, whose main function is to absorb moisture from the refrigerant and prevent excessive moisture in the refrigerant from reducing cooling capacity. When the desiccant inside the receiver-drier becomes saturated, it can no longer filter out moisture. Methods for maintaining a car air conditioner: 1. Comprehensive inspection of the air conditioner: When using the air conditioner for the first time in summer, inspect the air conditioning system, such as checking the refrigerant and whether the air filter is too dirty through the receiver-drier, and whether there are foreign objects in the radiator. 2. Pay attention to cleaning the air conditioner: Some beginners only think about cleaning the air conditioner when its performance deteriorates, which is incorrect. The air filter should be replaced regularly because Beijing's spring has a lot of sand and flying willow catkins, which can stick to the filter and breed bacteria, causing a musty smell in the air conditioner. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning. 3. Do not turn off the air conditioner immediately after parking: After reaching their destination, car owners usually turn off the air conditioner and leave immediately. Unlike in autumn and winter, the significant temperature difference between the inside and outside of the car in hot summer can cause the air conditioning system to become moldy and breed mold.
