H4L and L4L are two modes of four-wheel drive systems. Four-wheel drive systems are divided into part-time four-wheel drive and full-time four-wheel drive. The differences between H4L and L4L are as follows: 1. H4L is the high-speed four-wheel drive mode: When the H4L high-speed four-wheel drive lock mode is selected, the central Torsen limited-slip differential is locked, and the front and rear axles are connected. This function locks the power distribution between the front and rear wheels at 50% each. This mode is suitable for low-traction surfaces such as rain, snow, gravel, or light off-road conditions. 2. L4L is the low-speed four-wheel drive mode: The torque is amplified by 2.566 times, used for extreme off-road conditions, such as muddy roads. 3. Note: Switching between H4F and H4L modes does not require stopping the vehicle, and there are no speed restrictions; it can be done as long as the engine is running.

What is the card placed in a car?

The card placed in a car is used to insert a memory card. Some cars have two memory card slots, one for storing maps and the other for storing music. Memory card slots are becoming less common in newer car models, and memory cards themselves are also becoming less prevalent. Many new cars are equipped with Carlife and CarPlay functionalities, one for connecting to Android phones and the other for connecting to iPhones. To use Carlife or CarPlay to connect to the car's infotainment system, a data cable is required. It is recommended that car owners use the original data cable, as it supports data transmission.

Are the Kilometers for Subject Two and Subject Three Counted Together?

The kilometers for Subject Two and Subject Three are not counted together. Subject Two is a field test, mainly consisting of five items, and does not involve kilometers. Subject Three is a road test, which has kilometer requirements. However, the new "Outline" states that each province should set relevant requirements for the training mileage of various license types based on actual conditions, but the minimum should not be less than 300 kilometers. The class hours mentioned in the new "Outline" refer to the basic class hour requirements for each vehicle type. If additional test content and items are required, corresponding class hours should be increased. Below are the new regulations: 1. Subject Two and Subject Three can be taken together: The new regulations also stipulate that "Safe and Civilized Driving Knowledge" teaching should be integrated with "Road Driving" teaching; "Basic and Field Driving" and "Road Driving" can be trained alternately. This means that students can combine theoretical learning with practical driving practice, integrating Subject Two and Subject Three. This approach not only saves time but also reduces the cost of the driving test. 2. Class Hours: Additionally, "Road Traffic Safety Laws, Regulations, and Related Knowledge" and "Safe and Civilized Driving Knowledge" teaching can be conducted through multimedia teaching, remote online teaching, traffic safety experiences, and other methods, with classroom teaching not less than 6 class hours.

What does CEO displayed on a car mean?

Car ECO refers to the economic mode or energy-saving mode of a car, which is the energy-saving mode in the car's engine system. It reduces unnecessary fuel consumption by controlling the transmission, throttle, brakes, engine speed, and vehicle speed. Currently, the ECO modes in cars on the market are mainly divided into active and passive types. The active type has a dedicated ECO button in the car, allowing the owner to choose whether to activate it based on different road conditions. The passive type is directly controlled by the onboard computer without requiring additional operation from the owner. ECO is just an auxiliary system for vehicle energy-saving. Whether a car consumes fuel or not depends most critically on the owner's driving habits.

What are the differences between sedans, SUVs, and MPVs?

The differences between sedans, SUVs, and MPVs are reflected in their characteristics and target users. Different characteristics: Sedans are the most common and traditional type of vehicle, featuring a lower and more flexible design, which can be further divided into three-box and two-box cars. SUV stands for Sport Utility Vehicle, which can be simply understood as a "raised" sedan. As a result, SUVs have a higher center of gravity, offering more spacious interiors and better visibility. MPVs are relatively less common. Compared to sedans and SUVs, the most notable feature of MPVs is their passenger capacity. Typically, an MPV can seat seven people, while SUVs and sedans accommodate five. Due to their longer bodies and flexible seating arrangements, MPVs also offer considerable cargo space. Different target users: Compared to SUVs and MPVs, sedans have a lower center of gravity, making them more agile and suitable for urban roads. Additionally, with the same engine displacement, sedans are lighter and thus more fuel-efficient. SUVs have better off-road capability, making them the preferred choice for frequently driving on muddy or rough terrain. Moreover, if family members are larger in size, an SUV with more spacious interiors might be a better option. For family use, MPVs are ideal for large families, allowing everyone to travel together in one vehicle. They are also indispensable for commercial purposes. If work or business requires transporting goods or multiple people, an MPV is the best choice.
