BYD tire pressure monitoring signal reset method is: 1. In the vehicle's central control screen, click Settings; 2. Select the Vehicle tab; 3. Click the Maintenance option on the left; 4. After entering the interface, you can see the Tire Pressure Monitoring System, click Tire Pressure Reset; 5. After confirming the conditions required by the vehicle, click OK to reset and eliminate the tire pressure fault light. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Generally, an alarm will sound when the pressure is below 1.8 bar or above 3.0 bar. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the original data, causing the tire pressure monitoring indicator light to illuminate. At this time, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged due to impact while driving, it will also cause the tire pressure fault light to illuminate. For sensor damage issues, only a new replacement can be installed.

When encountering abnormal tire pressure monitoring signals in a BYD vehicle, I first pull over to check if there's an actual tire issue, such as visible nails or leaks. If nothing major is found, I manually measure the pressure of all four tires using a tire pressure gauge. If the pressure is normal but the warning light remains on, it's likely a sensor issue—like a depleted battery or internal moisture causing a short circuit. If the pressures are uneven, I promptly inflate or adjust them to avoid blowout risks. With over a decade of driving experience, I know BYD systems often false-alarm due to road interference; a quick reset at the dealership usually fixes it, hassle-free. Regular maintenance includes cleaning wheel sensors and avoiding deep puddles to extend battery life by 2-3 years. Never ignore this warning—it saves fuel and lives on highways.

What to Do When a Vehicle Falls into Water?

Here are the steps to handle a vehicle falling into water: 1. Open the windows immediately: As soon as the car falls into water, open the windows to prevent the doors from becoming impossible to open once the car sinks. Allowing water to flow into the car quickly ensures that the pressure on both sides of the door equalizes, making it possible to open the door. If the windows cannot be opened, use an object to break the window, such as the car headrest. The correct method is not to smash but to pry—aim for the window gap, insert, and pry the glass apart. Besides the headrest, tools like a safety hammer or fire extinguisher can be used to break the window, preferably targeting the edges or corners for easier breakage. 2. Open the door promptly: Do not wait until the water reaches the lower edge of the window before attempting to open the door, as the water pressure inside the car will be at its highest, making it very difficult to open. When opening the door, pull the inner handle and use your foot to push at an appropriate angle, which is more effective than the usual door-opening action. 3. If all four doors and windows fail to open as the car submerges, consider escaping through the sunroof. 4. Trunk escape: If the sunroof escape fails, opt for the trunk. Generally, when a car sinks, the front tilts downward while the rear floats upward before gradually sinking. At this point, unfasten the seatbelt, quickly crawl to the rear with the key, fold down the rear seats, locate the trunk release latch, and escape through the trunk. 5. Typically, a car will fill with water within 1-2 minutes. Stay calm during this time. Once the car is fully submerged, push the door open forcefully, swim to the surface as quickly as possible, or climb onto the roof to await rescue. Additionally, those in the water can grab floating objects like basins or fuel tanks, submerging the openings underwater or blocking them to use as flotation devices, thereby extending survival time.

What Causes Insufficient Transmission Pressure?

Here are the reasons for insufficient transmission pressure: 1. Insufficient hydraulic fluid in the transmission or the hydraulic fluid does not meet the specified standards. Generally, such transmissions must use the specified hydraulic fluid, such as No. 8 hydraulic transmission fluid or the manufacturer's designated hydraulic fluid. Ordinary hydraulic fluid is not allowed as a substitute. 2. The oil filter in the oil pan is clogged, resulting in insufficient hydraulic fluid flow. This filter is usually a metal mesh-type filter, and the most common issue is that the oil filter is not replaced for a long time, causing its surface to be clogged with various impurities, gum, metal debris, etc. 3. The oil pipe from the oil pan to the transmission pump is leaking air or has internal damage or delamination. Air leakage can cause the transmission pump to draw insufficient oil or fail to draw oil at all, while delamination can narrow the hydraulic fluid passage, both leading to insufficient hydraulic system pressure. 4. The transmission pump is damaged or excessively worn, resulting in insufficient pressure. Alternatively, the transmission pump drive mechanism (shaft gear) is damaged, preventing the transmission pump from rotating. The most common issue is excessive wear of the internal splines of the shaft gear, which prevents it from driving the transmission pump.

What to Do When a New Energy Vehicle Gets Flooded

When a new energy vehicle is flooded, the first step is to clean the dirt inside and outside the vehicle. Cleaning the exterior is straightforward, but the interior requires professional assistance. Then, park the car in the sunlight, open the windows for ventilation, and dry it out. Use the onboard computer for self-diagnosis to check if all vehicle equipment is functioning properly. For the flooded chassis, a thorough inspection is necessary, and rust-proof spray should be applied if needed. There are three main reasons why electric vehicles may encounter issues when flooded: 1. Issues with the sealing of the motor and battery: If the battery sealing meets relevant standards, there is no need to worry about flooding. Modern electric vehicles typically use permanent magnet synchronous motors, which have undergone water immersion tests and can operate underwater as long as the motor sealing remains intact. 2. Damaged wiring harnesses: Problems with wiring harnesses in electric vehicles are not difficult to resolve. Ensuring proper sealing of the motor and battery means the vehicle can theoretically continue driving as long as the driver has oxygen supply. 3. Insufficient waterproofing standards: The battery pack of an electric vehicle consists of battery cells enclosed in a metal casing. The waterproof standard for the battery pack casing is IPX7, meaning it can be submerged underwater for over half an hour without water ingress.

How Many Hours of Driving Constitutes Fatigue Driving?

According to Article 62 of the "Regulations for the Implementation of the Road Traffic Safety Law," continuous driving of a motor vehicle for more than 4 hours without stopping for a break or with a break time of less than 20 minutes is considered fatigue driving. Fatigue driving is identified when the driving duration exceeds 4 hours or the rest time is less than 20 minutes. The following are situations where fatigue driving is prone to occur: 1. Driving in summer is more likely to lead to fatigue driving. Firstly, the high temperature inside the vehicle and poor air circulation can easily cause the driver to become fatigued. Mental fatigue leads to slower thinking, and drowsiness is especially common in the afternoon. Continuing to drive under these conditions can easily result in accidents. 2. High-speed driving is prone to fatigue driving. When driving at high speeds, the driver needs to be fully concentrated, with the mind constantly in a state of high tension. Prolonged driving increases fatigue, and even a slight lapse in attention can lead to an accident.

Under what circumstances should high beams be turned on?

Here are the situations where high beams should be used: 1. When approaching an oncoming vehicle, you may switch to high beams; 2. When overtaking, turn on the turn signal and use the high-low beam switch to alert the vehicle ahead; 3. When passing through an intersection, use the high-low beam switch to alert vehicles on both sides of the intersection to pay attention; 4. When there are no other lighting facilities on the road and no oncoming vehicles, high beams can be used. Below is additional information: Generally, it is best not to use high beams when driving in the city because lighting conditions are usually good. The high angle of high beams can easily dazzle oncoming drivers and pedestrians, affecting their vision, which is unsafe and considered impolite driving behavior.

What are the commonly used air conditioning refrigerants nowadays?

Nowadays, the commonly used air conditioning refrigerant models include R22 refrigerant, R-134a refrigerant, R290 refrigerant, R410A refrigerant, etc. The following are the differences between these refrigerant models: 1. Environmental friendliness varies: R22 is a single refrigerant, chemically known as "chlorodifluoromethane," with a boiling point of -41°C. It is colorless and odorless but belongs to the Freon family. When released into the air, it may damage the ozone layer, causing environmental issues. In contrast, R-134a refrigerant is relatively more environmentally friendly and is currently a commonly used refrigerant. 2. Different usage areas and environments: R-134a (tetrafluoroethane) has a boiling point of -26.5°C, which is relatively low. When used in heat pumps, once the ambient temperature drops, the heat efficiency of the heat pump decreases. Therefore, this refrigerant is not as widely used as R22 and is generally employed indoors or in tropical regions. 3. Safety levels differ: R290 is a new environmentally friendly refrigerant, but when mixed with air, it can easily cause safety accidents such as explosions. Other refrigerants are relatively safer and do not pose explosion risks.
