Auto Start-Stop Function, also known as the Engine Auto Start-Stop System. Simply put, it automatically shuts off the engine when the vehicle comes to a temporary stop (such as waiting at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. The purpose of the Auto Start-Stop Function is to reduce emissions and lower fuel consumption during stops at traffic lights or short-term parking. Below is an introduction to the Auto Start-Stop Function: 1. The working principle of the Start-Stop System is that when the vehicle stops due to congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates there is enough energy for the next start. 2. Once these three conditions are met, the engine automatically stops. When the traffic light turns green, the driver presses the clutch, and the 'start stopper' can be activated, quickly restarting the engine.

What Causes the Brake Squealing in Mercedes-Benz E300?

Brake squealing occurs due to reasons such as worn brake pads leading to the backing plate grinding against the brake disc, hardened brake pads, or foreign objects lodged in the brake pads. Below are detailed explanations of the causes: Introduction to Checking the Causes of Squealing: When encountering squealing, the first step is to inspect the thickness of the brake pads, as this is fundamental to ensuring driving safety. Even if the brake pads are not worn thin, they may still produce noise during braking, similar to the sound of grinding against the wear indicator. This is caused by larger metal particles within the brake pads rubbing against the brake disc, resulting in a metal-on-metal friction sound. This is a normal phenomenon and does not indicate any quality issues with the brake pads. Other Causes of Brake Squealing: During the break-in period of a new car, the bedding-in of the brake pads is a crucial phase. Typically, after driving a few hundred kilometers, the braking performance will feel more comfortable. Similarly, newly replaced brake pads also require a break-in period to better integrate with the existing brake disc. Initially, the brakes may feel very stiff, and it usually takes a few hundred kilometers of driving before they start to feel better.

Where is the fog light fuse located?

Under the steering wheel, the fourth one (marked with the number 4). Below is relevant information about fog lights: 1. Introduction: Installed at the front of the car, slightly lower than the headlights, they are used to illuminate the road during rainy or foggy weather. Due to low visibility in foggy conditions, the driver's line of sight is limited. The lights can increase the running distance, especially the strong light penetration of yellow anti-fog lights, which can improve the visibility of the driver and surrounding traffic participants, allowing oncoming vehicles and pedestrians to spot each other from a distance. 2. Classification: Anti-fog lights are divided into front fog lights and rear fog lights. Front fog lights are generally bright yellow, while rear fog lights are red. The symbol for the rear fog light differs slightly from that of the front fog light; the front fog light symbol has downward light lines, whereas the rear fog light's are parallel, usually located on the dashboard inside the car. Since anti-fog lights are bright and highly penetrating, they do not cause diffuse reflection due to fog, so proper use can effectively prevent accidents.

Is gear shifting done manually or by following voice prompts?

Gear shifting is done by following voice prompts. When you hear the voice prompt for gear shifting, first press the accelerator to increase the speed in 2nd gear to 25 km/h, then press the clutch and shift to 3rd gear, release the clutch, and press the accelerator to increase the speed in 3rd gear to 30 km/h - 35 km/h, then shift to 4th gear, and finally downshift to 3rd gear. Below is a detailed introduction to the method of gear shifting for the third subject of the driving test: 1. Upshifting method: Start in 1st gear, quickly shift to 2nd gear after accelerating, and then shift to 3rd gear after further acceleration. After that, you can shift to 4th gear by accelerating. 2. Downshifting method: Downshifting requires first pressing the brake to reduce speed, then pressing the clutch to downshift. Quickly press the clutch, slowly release the clutch, slowly press the accelerator, and slowly release the accelerator. When preparing to shift gears, first slowly release the accelerator, but if the accelerator is not fully released when the clutch is pressed, you can still immediately release the accelerator without affecting the stability of the car.

Where is the air conditioning filter of Roewe 750 located?

Roewe 750's air conditioning filter is located in the engine compartment, beneath the front windshield. If you wish to replace the air conditioning filter, it is recommended to visit a 4S shop or a professional auto repair shop and have a technician perform the replacement. The function of the air conditioning filter is to filter out particles and impurities in the air, ensuring fresh air inside the vehicle. Over time, the air conditioning filter can become clogged. If it is not replaced promptly after clogging, it will no longer serve its filtering purpose.
