Mercedes-Benz left rear door cannot be opened from the inside because the child safety lock is engaged. There is a switch on the door frame; flipping it will allow the door to open. Some car owners believe that simply locking the central control lock before driving or setting the auto-lock feature while driving can ensure the safety of children in the back seat. Additional Information: 1. The Role of Child Safety Locks: For the safety of children during travel, the child safety locks on the rear doors should be engaged. Once the child safety lock is activated, no matter how much a child plays around in the back seat, they cannot open the door from the inside. This ensures the child's safety and allows the driver to focus more on driving without worry. 2. Precautions: When opening the car door from inside, it's important to first open it slightly to check for any oncoming traffic from behind. Only after confirming it's safe should one exit the vehicle; caution is necessary. The driver should remind anyone preparing to exit the car to check for approaching vehicles. The driver can assist by checking through the rearview mirror to prevent passengers from overlooking potential hazards.

How to Open the Car Fuel Tank Cap?

Opening the car fuel tank cap can be done in the following ways: 1. Mechanical key opening method, which is more complex. This method is commonly found on rugged SUVs, such as the JEEP Wrangler, Haval H5, etc. 2. The more common method nowadays is having a switch button inside the car, which is more convenient compared to the mechanical key method but may lead to refueling without turning off the engine, so drivers need to be more cautious. 3. Direct press-to-open method. No action is required from the driver, and the fuel attendant can directly proceed with refueling.

What is the battery degradation of a Tesla after 7 years of use?

The battery degradation of a Tesla after 7 years of use is 5.4%. Here are the relevant details: 1. Precautions: Charge the vehicle when the remaining battery level is between 5%-10%, and only charge it up to 90%-95%. This helps maintain battery life and prevents excessive degradation of the Tesla car battery. 2. Regulations: According to domestic policies, electric vehicles should provide an 8-year or 150,000-kilometer warranty for the battery. During the warranty period, battery degradation should not exceed 30%. If the battery degradation is severe, it can only be replaced. Tesla has made a product quality assurance commitment for the power battery and drive unit.

Can eCVT Withstand High Torque?

eCVT has no direct relation to withstanding high torque. Understanding eCVT: eCVT is not a traditional transmission in the true sense. It consists of a planetary gear set connecting an Atkinson cycle engine and two electric motors, capable of transmitting various torque levels from the engine without loss. The strong initial acceleration in hybrids is due to electric motors being able to instantly deliver maximum torque at any RPM, which is unrelated to eCVT. High Efficiency of eCVT: The mechanical connection in eCVT bypasses any clutch or torque converter, making its efficiency primarily dependent on the electrical circuit's efficiency.

How Many Amps is a Car Generator Current?

Car generator outputs a maximum current of 100A. Below is the relevant introduction about car generators: 1. Function: The car generator is the main power source of a vehicle. Its function is to supply power to all electrical equipment (except the starter) when the engine is running normally (above idle speed), while also charging the battery. 2. Principle: When the switch is closed, the battery provides the current first. The circuit is: battery positive → charging indicator light → regulator contact → excitation winding → ground → battery negative. At this time, the charging indicator light will illuminate because there is current passing through it.

What is the Difference Between Car Coolant and Antifreeze?

Car coolant and antifreeze differ in the following aspects: 1. Antifreeze is suitable for all seasons. Both the water reservoir and radiator in a car can be filled with antifreeze to regulate temperature differences. 2. Coolant contains water and antifreeze. Water is a commonly used cooling substance, but its effectiveness is inferior to antifreeze. Typically, water and antifreeze are mixed together when added. 3. Due to significant temperature variations between northern and southern regions, their usage processes also differ greatly. Coolant works best in southern areas, while its use in northern regions is problematic as frozen scale deposits can affect driving performance.

What Causes Moisture in Car Exhaust?

The main reasons for moisture in car exhaust are as follows: 1. Part of the water flowing from the exhaust pipe comes from the moisture in the fuel, and part comes from the humidity in the air, especially during cold seasons or when the weather is particularly humid. 2. The car expels the combustion byproducts, which cool down in the exhaust pipe and form water. The amount of water flow depends on the car's performance and displacement; cars with better performance and larger displacement tend to have more water flow. 3. The car engine inhales air and atomized gasoline, which is then ignited by the spark plug to perform work. After complete combustion, the combustible gas becomes exhaust, the main components of which are carbon dioxide and water vapor.
