L4 stands for Low-range 4WD (Four-Wheel Drive), while H4 stands for High-range 4WD. Low-range 4WD uses a small gear to drive a larger gear, allowing the engine to produce greater torque output. This mode is used when the vehicle requires high torque. High-range 4WD locks the power distribution between the front and rear wheels, with each receiving 50% of the power. This mode is suitable for conditions with low traction or specific terrain requirements. Four-wheel drive refers to a vehicle maintaining all four wheels driving throughout the journey, with the engine's torque distributed to the front and rear wheels at a fixed ratio. This driving mode ensures excellent off-road and handling performance at all times.

What is the fuel tank capacity of the Honda Civic in liters?

Honda Civic 2022 offers 6 models, all with a fuel tank capacity of 47 liters. The vehicles are equipped with CVT continuously variable transmission and front-wheel drive. In the same class, the 2021 Buick Excelle has a fuel tank capacity of 44 liters, the 2021 Ford Escort has a 50-liter tank, and the 2021 Toyota Corolla also has a 50-liter tank. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, which is designed to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, marked with E (empty) and F (full). When the needle is close to E, it indicates low fuel, while near F means the tank is nearly full.

How to turn off eco mode in Leiling?

Leiling mainly has the following two models, and the methods to turn off eco mode vary between different models. 1. The Toyota Leiling 1.6T does not have an eco switch function. 2. The Toyota Leiling 1.8T has an eco switch function, which can be turned off in the instrument menu settings. Additional content: 1. Exterior. The new Leiling has added a sports package for the sports version, including front and rear aerodynamic bumpers, a sporty mesh piano black front grille, and sport-specific seats. The gasoline sports version also features a lowered body stance. 2. Interior. The sports version adds red trim elements distributed on the door panels and center console, with a red and black color scheme enhancing the sporty feel. The overall design style continues that of the previous Leiling model, with no significant changes. Details include the addition of a front and rear sliding function for the front armrest, improving practicality. 3. Powertrain. The gasoline version still uses a 1.2T+CVT powertrain combination, with a maximum power of 85kW and peak torque of 185N·m.

Causes and Solutions for Low Oil Pressure

Here are the possible causes and solutions for low engine oil pressure: 1. Wear and tear of the oil pump, or wear or foreign objects in the pressure relief valve. 2. Insufficient oil storage. 3. Oil is dirty or too viscous after prolonged use. 4. Excessive wear of components, large clearance in camshaft bearings. 5. Faulty oil pressure sensor, gauge, or circuit. Here are the solutions for low engine oil pressure: 1. Lift the car, inspect along the pipeline, identify the problematic area, and repair or replace it promptly. 2. Add a bottle of the oil used during maintenance. Of course, identify and fix any oil seepage or leakage issues. If the engine is burning oil, take it to a 4S shop for inspection and repair. 3. First, clean or replace the oil pump, then refill the car with new oil. After the change, ensure oil quality and strictly adhere to maintenance standards.

What does left tire pressure loss mean?

Left rear tire pressure loss indicates abnormal tire pressure in the left rear tire, which requires calibration. Standard tire pressure values: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure should not exceed 3.5bar. There are generally three reasons for abnormal tire pressure: Tire pressure abnormality: The system typically alerts when pressure falls below 1.8bar or exceeds 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring system not reset: After inflating tires, if the tire pressure monitoring system isn't reset promptly, it continues to display previously recorded data, causing the tire pressure warning light to illuminate. Simply performing a tire pressure reset will resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor gets damaged during driving (e.g., by tire impact), it will trigger the tire pressure warning light. For sensor damage issues, only complete replacement with new components is possible.

Which engine oil is more suitable for cars in winter?

Because the temperature is relatively low in winter, the low-temperature fluidity requirements for engine oil are higher. It is recommended to use 0W grade engine oil. Below are the relevant introductions: 1. The engine oil used in winter must meet three major characteristics: low viscosity, low pour point, and good anti-wear performance, so as to provide good protection for the engine. 2. The temperature in winter is relatively low, so the fluidity of engine oil in cold conditions is poor. Some engine oils may even solidify in environments below minus ten degrees Celsius. Therefore, the engine oil used in winter needs to have good low-temperature fluidity. 3. The number before the "W" in the engine oil grade represents the low-temperature fluidity of the engine oil. 4. 0W indicates a minimum operating temperature of -35°C; 5W can operate in environments with a minimum temperature of -30°C; while 10W can only be used in environments above -25°C, and so on. 5. Car owners can choose the engine oil with the required low-temperature fluidity according to the local minimum temperature. The lower the temperature, the better the low-temperature fluidity of the engine oil required.

What cars are built on the CMA platform?

CMA platform includes models such as the Lynk & Co 01, Lynk & Co 01 PHEV, Lynk & Co 02, Lynk & Co 03, Lynk & Co 05, and the Volvo XC40. Here is some relevant information about the CMA platform: 1. The CMA (Compact Modular Architecture) platform features high flexibility and scalability, making it suitable for various vehicle body styles and sizes. It supports both traditional and new energy powertrains, including HEV (Hybrid Electric Vehicle) and PHEV (Plug-in Hybrid Electric Vehicle) systems. This provides the technical foundation and assurance for developing vehicles with safety quality, intelligent connectivity, efficient powertrains, and excellent driving experiences. 2. In terms of safety, vehicles built on the CMA platform are designed with body structures that meet and exceed crash standards in China, Europe, and the U.S. They are equipped with advanced intelligent connectivity systems, allowing the car to stay connected to the internet even without a smartphone inside. Through in-car apps, CarPlay, CarLife, and other connectivity systems, seamless integration between people, cars, and the world is achieved.
