Why is the tire pressure monitoring warning light on?

The illumination of the tire pressure warning light indicates that the current pressure deviation among the four tires is too large or that there is insufficient air, suggesting an issue with the vehicle's tire pressure. It is recommended to visit a professional 4S shop for inspection. Below are the reasons why the tire pressure monitoring light may be on: 1. The tire pressure monitoring light may be on due to a punctured tire. This situation usually involves very slow air leakage, making it difficult to immediately identify which tire is affected. In such cases, a tire pressure gauge can be used for measurement. 2. Sometimes, the tire pressure monitoring light is on because the tire pressure is too high. Standard tires: 2.4-2.5 bar; reinforced tires: 2.8-2.9 bar; maximum pressure: should not exceed 3.5 bar. Therefore, if any tire exceeds 3.0 bar, it may trigger the tire pressure monitoring light. 3. The tire pressure monitoring light may be on due to prolonged driving with low tire pressure. If a tire's pressure is too low, high-speed operation can cause the tire temperature to rise, leading to increased tire pressure. In such cases, it is advisable to stop and rest or replace the tire with a spare. 4. The tire pressure monitoring light may be on due to prolonged lack of inflation, resulting in low tire pressure.

What does MT mean for vehicles?

MT in vehicles stands for manual transmission. The principle of a manual transmission vehicle is that the power input shaft is connected to the clutch, and the power transmitted from the clutch is directly passed to the gear set through the input shaft. The steps to start a manual transmission car are: 1. Sit in the car and start the engine; 2. Press the clutch and shift into first gear; 3. Slowly release the clutch while gently pressing the accelerator; 4. Fully release the clutch, and the car starts moving. Precautions for starting a manual transmission car: 1. Do not release the clutch too quickly; lift it slowly; 2. Press the accelerator only after the engine and drive shaft are connected; 3. Gently press the accelerator during the semi-engagement phase, then release the clutch; 4. Release the handbrake before starting.

How Long Should You Charge a Car Battery?

It takes about 10 to 15 hours to fully charge a car battery. The functions of a car battery include: 1. Providing power to the engine starting system, ignition system, and the vehicle; 2. Supplying power to the car's electrical equipment when the engine is off or idling at low speed; 3. Assisting in power supply when the electrical demand exceeds the generator's capacity; 4. Acting as a voltage stabilizer for the vehicle's electrical system, mitigating voltage surges and protecting the car's electronic devices. Methods to maintain a car battery: 1. Regularly clean the battery; 2. Minimize the use of electrical equipment when the engine is off; 3. Replace the battery periodically; 4. Start the car regularly.

Should You Depress the Clutch When Starting the Car?

The clutch should be depressed when starting the car. The functions of the clutch are: 1. Gradually increase the driving force of the car for a smooth start; 2. Temporarily separate the engine and transmission for gear shifting; 3. Prevent overload of the transmission system; 4. Reduce torsional vibration impact from the engine and extend the service life of transmission gears. Severe clutch wear can lead to: 1. Car slippage and insufficient power; 2. Difficulty in starting the car or ignition; 3. Poor climbing performance and increased fuel consumption. The working principle of the clutch is: 1. When the inner ring is fixed, the outer ring rotates clockwise, and the wedge block does not lock, allowing the outer ring to rotate freely; 2. When the outer ring rotates counterclockwise, the wedge block locks, preventing the outer ring from rotating.

What is the Principle of a Clutch?

The principle of a clutch is: 1. When the inner race is fixed, the outer race can rotate freely in the clockwise direction as the wedges do not lock; 2. When the outer race rotates counterclockwise, the wedges lock, preventing the outer race from rotating. The main functions of a clutch are: 1. Gradually increasing the driving force of the car to ensure a smooth start; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload in the transmission system; 4. Reducing torsional vibration impacts from the engine and prolonging the lifespan of transmission gears. Severe clutch wear can lead to: 1. Car slippage and insufficient power; 2. Difficulty in starting the car or ignition problems; 3. Poor climbing performance and increased fuel consumption.

Why is the air conditioning in the Vezel not cooling?

The reasons why the air conditioning in the Vezel is not cooling are: 1. Lack of refrigerant; 2. Damage to the air conditioning flap; 3. Loose drive belt of the car air conditioning compressor; 4. Clogged air filter and filter screen; 5. Moisture infiltration in the refrigeration system. The functions of the air conditioning are: 1. Achieving cooling effect through the continuous circulation of refrigerant; 2. Removing dust, odors, smoke, and toxic gases from the air inside the car, making the air inside the car fresh and increasing the relative humidity of the air inside the car. Taking the 2020 Vezel as an example, it belongs to a small SUV, with body dimensions of: length 4328mm, width 1772mm, height 1605mm, wheelbase of 2610mm, fuel tank capacity of 50l, and curb weight of 1227kg.
