How to Activate the Automatic Braking System in Mercedes-Benz?

To activate the automatic braking system in Mercedes-Benz, follow these steps: Press the button on the steering wheel to access the assistance menu, select the Collision Prevention Assist system, choose to enable it, and press the OK button. Below is an introduction to the automatic braking system: 1. The car's automatic braking system refers to the system that, during normal driving without adaptive cruise control, can actively generate braking effects to slow down or stop the vehicle when encountering sudden hazards, thereby preventing rear-end collisions. 2. The installation of an automatic braking system does not alter the original structure of the car, does not affect the car's performance, and automatically activates when the car is about to collide with an object ahead or when there is an obstacle in front but the driver does not react.

Why Does the Water Temperature Drop While Driving?

The reasons for the drop in the water temperature gauge while driving are as follows: 1. Faulty water temperature sensor; wiring issues; 2. Malfunction of the car's dashboard water temperature gauge. Here are the solutions to address the drop in the water temperature gauge: 1. If the water temperature gauge drops while driving, you can use the elimination method to check. 2. Disconnect the plug of the car's water temperature sensor and observe whether the water temperature gauge rises. If it doesn't rise, it indicates a fault in the car's wiring or the water temperature gauge. If it does rise, it means the water temperature sensor is faulty, and you can visit the nearest 4S store or auto repair center for repairs.

What Octane Gasoline Should a Normal Car Use?

The selection of gasoline octane rating should be determined by the compression ratio of the car's engine. The appropriate fuel octane rating for the vehicle is usually indicated on the inside of the fuel tank cap. If it specifies 92-octane fuel, then use 92-octane. If it specifies 95-octane fuel, then use 95-octane. Whether the gasoline is 92 or 95 octane, the number represents the fuel's anti-knock performance. A higher octane rating indicates better anti-knock performance, but it does not necessarily mean higher fuel quality, contrary to the common belief that higher octane fuel is always better. For naturally aspirated engines, 92-octane gasoline is generally recommended. Higher-octane fuel has better anti-knock performance but burns relatively slower, which can lead to higher compression ratios in the engine, resulting in reduced power and increased temperatures. For turbocharged engines, manufacturers typically recommend 92-octane or higher. Using 95-octane gasoline not only ensures higher torque at low speeds but also helps reduce engine vibration and noise.

How many kilometers can you drive when the tire wears to the safety line?

Tires should not be driven when they wear to the safety line because at this point, the tire's drainage and grip are very poor, which may lead to loss of control or skidding during driving. It is necessary to replace the tire promptly. The safety line is usually located at the bottom of the tire grooves as a wear indicator. Its purpose is to remind the owner that if the tire tread wears down to this position, the tire must be replaced. The following are precautions for car tire maintenance: Pay attention to tire pressure: Tire pressure is crucial for tires. Both overinflation and underinflation can shorten the tire's lifespan. Underinflation increases tire deformation, leading to cracks on the sidewalls and excessive flexing, which generates heat and accelerates rubber aging, fatigue of the cord layers, and cord breakage. Regularly check front-wheel alignment: Front-wheel alignment significantly affects tire lifespan, with toe-in and camber being the primary factors. Excessive camber mainly accelerates shoulder wear, while incorrect toe-in (too small or too large) primarily accelerates wear on the inner or outer edges of the tire. Be mindful of driving habits: Choose smooth roads while driving to avoid sharp objects like stones, glass, or metal that may puncture or damage the tires. Avoid chemical spills that could adhere to or corrode the tires. When driving on roads with significant curvature, try to stay centered to reduce uneven tire wear caused by increased load on one side.
