Tire pressure monitoring system is a technology that uses wireless transmission. Its functions and precautions are as follows: Functions: Detect tire pressure to prevent tire blowouts. Accidents caused by tire blowouts account for a very high proportion of severe traffic accidents, and among all factors that can cause blowouts, insufficient tire pressure is the primary reason. Precautions: As the driving mileage increases, the tire pressure of a car undergoes subtle changes. Private car owners should pay attention to regular tire pressure monitoring. Excessive tire pressure reduces the contact area between the tire and the ground, leading to increased braking distance, which is not conducive to safe driving.

The tire pressure monitoring system is like a little assistant that keeps an eye on your tire pressure at all times. If any tire is low on air while driving, it will immediately alert you with a small indicator on the dashboard. The principle is that sensors measure the tire pressure in real time, and an alarm is triggered as soon as it falls below the set value. I think this feature is super practical, especially when driving on highways or traveling with family. Insufficient tire pressure can easily lead to a blowout, which is no joke. Nowadays, it's mandatory for new cars to be equipped with this system, which shows how important safety really is. During regular maintenance, don't just focus on the engine oil; remember to ask the mechanic to check if this system is functioning properly. The sensor batteries can last five to six years.

When Should the Car Transmission Fluid Be Changed?

Car transmission fluid should generally be changed every 40,000 kilometers. Transmission fluid is an oil product that keeps the gear system clean, ensuring the normal operation of the transmission and extending the lifespan of the transmission components. Transmission fluid is crucial for the transmission, as it ensures proper functioning and prolongs its service life. Performance indicators of transmission fluid: 1. Appropriate viscosity—automatic transmission fluid operates within a temperature range of -40°C to 170°C, which is quite broad. Automatic transmissions are highly sensitive to the working viscosity of the oil, and different types of transmissions require different viscosity levels. Therefore, the type of transmission fluid should not be changed arbitrarily for automatic vehicles. 2. Good anti-foaming properties—automatic transmissions can produce foam, which can cause significant harm to the transmission system. Foam can reduce the torque converter's power transmission efficiency and, in severe cases, interrupt oil supply. 3. Excellent anti-wear properties—good anti-wear performance is necessary to meet the requirements of planetary gear transmission and clutch plate operation.

How Often Should Car Air Conditioning Freon Be Replaced?

There is no fixed time for replacing car air conditioning Freon. Generally, when the cooling effect of the car air conditioner becomes poor, you can check whether the Freon is insufficient and replace or add it if necessary. For users who have used the car air conditioner for more than half a year, they can check whether there are obvious signs of oil leakage at the pipeline joints inside the car and the valve of the outdoor unit. If there is obvious oil leakage, it indicates that the machine is leaking, because oil and Freon are mutually soluble—oil leakage must mean Freon leakage, and Freon leakage must mean oil leakage. If the refrigerant is not replenished or replaced, it will lead to a decline in the cooling effect of the air conditioner, and it will take a long time to cool down. After the air conditioner is turned on normally for a period of time, the wind blowing on your body should feel very cool and quickly reach the set temperature. The outdoor compressor can work for a while and then stop for a while, just like a refrigerator, which indicates that it is normal. Otherwise, it may be necessary to replenish the refrigerant.

How Much Engine Oil Should Be Added During Car Maintenance?

During car maintenance, approximately 4 liters of engine oil should be added. The functions of engine oil are: 1. To alleviate friction and high temperatures; 2. To reduce gas leakage and prevent external pollutants; 3. To prevent contact between water, air, acidic harmful gases, and parts; 4. To buffer the pressure rise at the engine cylinder port; 5. To flush away dirt generated on the working surfaces of parts. The characteristics indicating the need for oil change are: 1. Check the viscosity of the oil—if there is no viscosity, the oil needs to be changed; 2. The oil color turns black; 3. Excessive black particles, metal shavings, or carbon deposits in the oil; 4. The oil smells abnormal. The method for changing engine oil is: 1. Lift the car, remove the protective plate, and place a container of about 10 liters under the oil drain screw; 2. Unscrew the oil drain screw, use an air gun to blow into the oil filler port for two minutes, then tighten the oil drain screw after draining and wipe it with a tissue to check for leaks; 3. Reinstall the protective plate and lower the car, then use a funnel to add oil into the filler port.

How to Check the Fuel Gauge on a Civic?

The Civic features an analog fuel gauge marked with the letters E and F, where F stands for Full and E indicates Empty. When the fuel icon lights up, it means the remaining fuel is low, and you should refuel as soon as possible. There is also a digital fuel gauge that displays the remaining fuel through illuminated bars. More bars indicate sufficient fuel, while only 1-2 bars suggest low fuel levels, requiring prompt refueling. More details are as follows: 1. The car fuel gauge is an indicator that shows the remaining fuel in the vehicle, serving as an important reference for drivers to determine whether to refuel. Understanding the structure and markings of the fuel gauge helps drivers accurately assess the remaining fuel or the gauge's functionality. 2. Various movements occur while driving, such as going uphill, downhill, braking, turning, or starting, which can cause changes in the float ball's height. This may lead to the warning light flickering on and off. Therefore, when checking the fuel gauge or its warning light, drivers should primarily rely on readings taken when the car is on a flat surface and moving in a straight line.
