After the engine is turned off, failing to turn off the air conditioning can damage the battery's lifespan and affect the engine's efficiency. Below are precautions for using the car's air conditioning: 1. Turn off the air conditioning in advance: It is best to turn off the A/C button one or two minutes before parking and turning off the engine. This allows the air to dry the moisture in the air conditioning vents and pipes, preventing bacterial growth inside the air conditioning system and reducing odor. 2. Turn off the engine after turning off the air conditioning: If the engine is turned off without turning off the air conditioning, the next time the vehicle is started, the engine will have to start with the air conditioning load. Therefore, the best practice is to start the vehicle and wait two or three minutes for the engine to be fully lubricated before using the air conditioning.

Why does BYD's DMi not have a transmission?

BYD's DMi technology is an improvement based on Honda's i-MMD technology as pure electric vehicle technology continues to mature, relying more on batteries and electric motors, thus eliminating the transmission. Below is the relevant introduction about BYD: 1. Engine direct drive is basically only used during high-speed cruising, where the requirements for engine power and torque are not too high. In other conditions, the vehicle is driven by the electric motor, with the engine generating electricity. 2. If BYD requires sudden acceleration at high speeds, the electric motor will assist in driving to meet the demand, but the efficiency of the electric motor decreases at high speeds, making rapid acceleration with DMi technology likely more challenging. 3. BYD's technology clearly prioritizes economy, making it more suitable for urban use, with occasional high-speed and long-distance travel, but it does not meet the demands of aggressive driving. For conditions requiring prolonged high-power driving, such as extended high-speed driving, DMi technology is not suitable. 4. Essentially, vehicles with DMi technology will only enter engine direct drive mode when speeds exceed 80 km/h. According to highway and road design standards, speeds above 80 km/h are unlikely to encounter significant slopes, and maintaining speeds above 80 km/h while climbing steep slopes is impossible. Therefore, this technology is well-suited for normal driving needs.

How to Add Windshield Washer Fluid?

Open the engine hood, and in the lower right corner of the engine compartment, you will find a white cap. This is where you add the windshield washer fluid. Below is relevant information about windshield washer fluid: 1. Windshield washer fluid is mainly divided into three categories. The first category: Summer-specific. This type of windshield washer fluid contains added insect-removing agents in its original composition, allowing it to quickly remove insect residues from the windshield. The second category: Ordinary winter windshield washer fluid. Also known as anti-freeze windshield washer fluid. This type can generally ensure that it does not freeze or damage car facilities when the outside temperature is below -20°C. The third category: Special anti-freeze windshield washer fluid. This type can remain unfrozen even at -40°C, making it suitable for use in extremely cold regions of northern China. 2. Windshield washer fluid is the common name for car windshield cleaning fluid. It is a type of automotive consumable. High-quality car windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. You can add up to approximately 1.5 liters of windshield washer fluid at a time.

Does turning on the car's heater consume more fuel?

Turning on the car's heater does not significantly increase fuel consumption. The car's air conditioning system only consumes engine power when operating in cooling mode, as the compressor engages, which in turn increases fuel consumption. Here’s how to use the car heater properly: 1. After starting the car, wait about 8-15 minutes for the engine coolant to reach normal operating temperature (indicated by the temperature gauge reaching the middle). 2. First, use the external air circulation mode to expel cold air from the cabin for 2-3 minutes, then switch to internal circulation. 3. Adjust to the heating mode—some cars use a red zone for this setting, while others use a sun symbol. 4. Do not turn on the AC (do not press the AC button), as the heater utilizes the car's own heat cycle, saving energy. 5. Set the fan to an appropriate speed and adjust the air vent direction. 6. Typically, direct warm air toward the front and footwell areas, while cold air is usually directed forward.

What is the difference between longitudinal and transverse engine placement?

The main differences between longitudinal and transverse engine placement are as follows: 1. The layout of the engine position is different. 2. Due to the different position layouts, the optimal power output direction of the engine varies. 3. Because of the above two characteristics, the best application and matching methods are different. 4. Transverse engines have a simpler structure, lower cost, and can expand the passenger compartment space, while longitudinal engine cars offer higher driving pleasure, better handling, and superior driving feel. 5. Cars with transverse engines have poorer handling and less driving pleasure. Longitudinal engines can encroach on passenger compartment space and are also more expensive.

Will the electronic eye capture an unclosed trunk?

The electronic eye will not capture an unclosed trunk, but it is considered a violation of the law. According to the implementation regulations of China's Road Traffic Safety Law, it is clearly stated: 1. When driving a motor vehicle, doors and compartments must be properly closed. Generally, if traffic police see this situation on the road, they will stop the vehicle and issue a verbal warning. 2. However, if the trunk is loaded with many items, making it impossible to close the door, this situation will be penalized. Extended content: When driving a motor vehicle, the following behaviors are prohibited: 1. Driving with doors or compartments not properly closed. 2. Hanging or placing items within the front or rear windows of the motor vehicle that obstruct the driver's view. 3. Making or receiving handheld phone calls, watching TV, or engaging in other behaviors that hinder safe driving. 4. Turning off the engine or coasting in neutral on steep slopes. 5. Throwing items onto the road. 6. Riding a motorcycle with hands off the handlebars or hanging items on the handlebars. 7. Driving continuously for more than 4 hours without stopping to rest or resting for less than 20 minutes. 8. Honking the horn in areas or sections where honking is prohibited.
