In summer, the car air conditioner is generally set to 26℃, which is the most comfortable temperature for Chinese people's physique. The car air conditioner switch is located on the car's center console. The A/C button is the switch for the air conditioner compressor, while for automatic air conditioners, the switch is the AUTO button. To turn on the air conditioner for cooling, press the A/C button or AUTO button, then adjust the fan speed and direction according to your needs. Below is an introduction to how the air conditioner works: After the engine starts, turn on the A/C switch, the electromagnetic clutch engages, and the engine's power is transmitted to the compressor. The compressor circulates the compressed refrigerant to the evaporator, where the refrigerant vaporizes, absorbs heat, and produces cold air. The fan then blows this cold air into the cabin.

In summer, I usually set the car air conditioning temperature between 23 to 24 degrees Celsius, which provides good cooling without making me feel too cold or too hot—just perfect for relaxing. Setting it any lower might cause a cold or make the compressor cycle on and off frequently, reducing efficiency. I typically use the auto mode, letting the system adjust the fan speed automatically, which is both convenient and efficient. During long trips, I switch to recirculation mode to prevent hot air from entering, but I turn on the fresh air mode every half hour for ventilation. Don’t forget to check the cabin air filter—dust buildup can affect cooling, so regular cleaning ensures proper airflow. This setup is both energy-efficient and good for the car, making driving more refreshing and reducing fatigue significantly.

What Do the Letters on Tire Ratings Mean?

Tire rating letters indicate the speed rating of the tire, where each corresponding letter represents the speed grade of the tire. The speed grade denotes the maximum speed at which the tire can carry a specified load under defined conditions. Tires are rubber products mounted on metal rims that roll on the ground, installed on vehicles or machinery. The functions of tires include: 1. Supporting the vehicle's weight and bearing the load; 2. Transmitting traction and braking torque to ensure adhesion between the wheels and the road surface; 3. Reducing and absorbing vibrations and impact forces during driving, ensuring safety, handling stability, comfort, and fuel efficiency.

How many kilometers should the transmission fluid of BYD Tang be replaced?

BYD Tang's transmission fluid should be replaced every 20,000 to 40,000 kilometers. The replacement method is as follows: 1. Start the vehicle to warm up the engine; 2. Remove the drain bolt; 3. Drain all the old fluid and reinstall the bolt; 4. Add new transmission fluid and check the fluid level. Transmission fluid serves to clean, lubricate, prevent rust, and dissipate heat in the transmission. Taking the 2021 automatic flagship model BYD Tang as an example, its body dimensions are: length 4870mm, width 1940mm, height 1720mm, wheelbase 2820mm, fuel tank capacity 68 liters, and curb weight 1895kg.

How to Activate ETC After Removal?

Methods to reactivate ETC after removal: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth is on". If "Tag Invalid" appears when inserting and removing twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually a download QR code is provided on the electronic tag), and enter the device activation interface. Click on "Device Connection" and wait patiently for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation. The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-removal button on the back of the OBU; a red light will briefly turn on, and the OLED screen will display "Tag Invalid, Please Insert Card", indicating the device is functioning properly. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then, peel off the protective film on the OBU adhesive and stick it to the installation location. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Promotes low-carbon travel by allowing vehicles to pass through toll stations without stopping, reducing noise and exhaust emissions, thereby minimizing pollution; Cost-saving: Reduces expenses by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Users also enjoy a 5% discount on toll fees; Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What Are the Solutions When Car Keys Are Lost Inside the Car?

Solutions when car keys are lost inside the car include: 1. Going home to retrieve the spare key; 2. Re-matching the key and replacing all car locks. Types of car keys: mechanical key, remote key, touchscreen LCD key, smart wristband key. Functions of car keys: 1. Quickly locate the vehicle using the remote alarm device; 2. Close windows after turning off the engine; 3. Automatically open the trunk; 4. Selectively open the driver's door. Principle of car keys: The car owner emits a weak radio wave, which is received by the car antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator motor or electromagnetic coil performs the action of unlocking or locking.

What are the reasons for a car stalling at idle?

The reasons for a car stalling at idle include clogged idle air ports, malfunctioning idle control devices, weak spark in individual spark plugs, poor valve sealing, intake manifold leaks, incorrect ignition timing, and improper idle adjustment. Below are specific causes and corresponding solutions: Intake manifold leaks: When unauthorized air, fuel vapors, or exhaust gases enter the intake manifold, it can cause the air-fuel mixture to become too rich or too lean, leading to unstable idle. In this case, the intake manifold should be replaced. Excessive carbon buildup in the throttle body: Carbon deposits in the throttle body and surrounding intake passages can alter the air passage cross-section, preventing the control unit from accurately regulating idle air intake. This can also lead to an overly rich or lean mixture, resulting in unstable idle. Cleaning the fuel system and inspecting the idle control valve for carbon buildup is necessary. Faulty intake system actuators: The engine's intake system has many actuators, such as the throttle motor, idle speed control motor, duty cycle solenoid valve, mass airflow sensor, and intake pressure sensor. Malfunctions in these components can cause unstable idle. Repairs should be performed at a 4S shop. Fuel system malfunctions: Issues like clogged fuel injectors, blocked fuel filters, obstructed fuel pump screens, faulty fuel pressure regulators, or clogged return lines can lead to incorrect fuel injection, causing the mixture to be too rich or lean and resulting in unstable idle. Repairs should be conducted at a 4S shop.
