How to Set the Ambient Lighting in Mercedes-Benz E300?

The ambient lighting button for the Mercedes-Benz E300 is located on the central LCD display. Press the vehicle's one-touch start button to power on the vehicle; otherwise, the ambient lighting cannot be adjusted. Then, tap the screen touch button on the right side of the steering wheel to activate the ambient lighting adjustment function on the central LCD display. After that, you can select different colors on the central LCD screen, which will cause the vehicle to display different ambient lighting effects. You will observe the body's ambient lighting changing colors based on the adjustments made on the central screen. Here is more information about ambient lighting: 1. The ambient lighting used in cars primarily employs LED materials, also known as light-emitting diodes. LEDs are solid-state semiconductor devices that work by converting electricity into light. Ambient lighting serves mainly as a decorative feature, typically installed in areas such as the dashboard, door panels, roof, and central console to enhance the overall interior ambiance. 2. When using ambient lighting, it is essential to adjust the brightness appropriately. If the ambient lighting is too bright, it can be harmful while driving. Excessive brightness may lead to misjudgments of the external environment and delay reactions to sudden events, which could have severe consequences. Therefore, it is important to use ambient lighting with caution.

Is Flashing ECU Harmful to Cars?

Flashing the ECU does pose certain risks to the vehicle. While it enhances power output, it also excessively consumes the engine's lifespan and is prone to carbon buildup. Moreover, once a vehicle's ECU has been flashed, dealerships may refuse warranty services if issues arise. Below are specific details about ECUs: 1. Components: Consist of a microcontroller (MCU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), as well as shaping circuits, drivers, and other large-scale integrated circuits. 2. Operating Parameters: ECUs typically operate within a voltage range of 6.5-16V (with voltage regulators at critical internal points), a current range of 0.015-0.1A, and a temperature range of -40℃ to 80℃. 3. Primary Function: Controls the vehicle's driving state and enables various functionalities. This is primarily achieved through data collection and exchange via various sensors and bus systems to determine vehicle status and driver intent, then manipulating the car via actuators.

What is the purpose of cleaning the throttle body?

Cleaning the throttle body can ensure smooth air intake, restore the vehicle's idle speed and emissions, and recover the vehicle's power. The following are specific details about the throttle body: 1. Definition: The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake manifold, it mixes with gasoline to form a combustible mixture, which then burns to produce power. It connects to the air filter at the top and the engine block at the bottom, often referred to as the throat of the car engine. 2. Classification: There are two types of throttle bodies: the traditional cable-operated type and the electronic throttle body. In traditional engines, the throttle body operates via a cable (flexible steel wire) or linkage, connecting the accelerator pedal at one end and the throttle linkage plate at the other. The electronic throttle body primarily uses a throttle position sensor to control the opening angle of the throttle based on the engine's power demand, thereby regulating the amount of air intake.

What is the formula for calculating engine displacement?

Engine displacement = Single cylinder displacement × Number of cylinders, Single cylinder displacement = (π × Bore × Bore) ÷ 4 ÷ 1000 × Stroke (unit: cc). Cylinder displacement is only an approximate value and will be higher than the labeled value. The bore is the diameter, usually measured in millimeters. The following is relevant information about displacement: 1. Concept of car displacement: Car displacement refers to the gas volume swept by the piston from top dead center to bottom dead center, also known as single cylinder displacement, which depends on the bore and piston stroke. Engine displacement is the sum of the working volumes of all cylinders, usually expressed in milliliters. Engine displacement is one of the most important structural parameters, more representative of engine size than bore and number of cylinders. Many indicators of the engine are closely related to displacement. 2. Meaning of "golden displacement": It has the characteristics of fuel economy; good handling, power, and comfort; and can meet consumers' various usage needs.

Why Are Used Cars So Cheap and Are They Worth Buying?

As long as it's a new car, whether it's never been driven or has been used for a month, its value typically depreciates by up to 20% as soon as it hits the road. This is commonly referred to as the '20% depreciation upon landing' for new cars. The first year sees the fastest depreciation, while cars around 3 years old retain their value the best. Therefore, used cars aged 3-5 years are highly favored by car owners due to their excellent cost-performance ratio. Used cars can indeed be purchased, but the following points should be noted: 1. Choose Reputable Dealers: Always buy from reputable dealers to ensure effective handling of any issues post-purchase. Also, be cautious with online used car platforms—while they can be trusted, don't rely on them entirely. 2. Pay Attention to Mileage: This is mainly relevant for decommissioned commercial vehicles, which not only have high mileage but also limited remaining service life. Operational vehicles are mandatorily scrapped after eight years, leaving you with only a year or two of use at most. 3. How to Select a Car: After considering the purchasing channels, here's how to choose a car: First, browse online to see if any models catch your eye, then compare prices across platforms (for reference only). Once you've made a selection, visit a used car market to inspect potential models in person.

Can Second-hand Car Insurance Be Transferred Without Ownership Transfer?

No. According to the new regulations on auto insurance, when the ownership of a vehicle is transferred, the corresponding compulsory traffic insurance will automatically be transferred to the new owner. This is because compulsory traffic insurance is mandatory under national law. However, commercial insurance does not fall under the mandatory transfer category. The original owner typically cancels the commercial insurance that has not expired, and the new owner can then purchase it separately. Below is an introduction to how second-hand car insurance can be transferred: 1. Change of policyholder: The new owner of the second-hand car, with the transfer receipt, a copy of the vehicle license, the original insurance policy, their ID card, and the original insurer's ID card, can fill out a transfer application form at the original insurance company to complete the endorsement transfer. 2. Application for cancellation: To apply for cancellation, only the premium from the start of the insurance period to the cancellation date needs to be paid, and the remaining premium will be refunded by the insurance company accordingly. 3. Policy process: The transfer of second-hand car insurance essentially involves changing the beneficiary and license plate number on the original insurance endorsement after the second-hand car transaction.
