The following distance when the speed exceeds 100 km/h should be more than 100 meters. Below is additional information on following distances: 1. When visibility is less than 200 meters: Turn on fog lights, low beams, marker lights, and front and rear position lights. The speed should not exceed 60 km/h, and the distance from the vehicle in front in the same lane should be more than 100 meters. 2. When visibility is less than 100 meters: Turn on fog lights, low beams, marker lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 40 km/h, and the distance from the vehicle in front in the same lane should be more than 50 meters. 3. When visibility is less than 50 meters: Turn on fog lights, low beams, marker lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 20 km/h, and you should exit the highway at the nearest exit as soon as possible.

When driving on the highway at speeds over 100 km/h, it's essential to maintain a greater following distance to avoid danger. I often use the 'two-second rule' to judge: pick a fixed point by the roadside, like a billboard or milestone, and when the car in front just passes that point, I start counting '1001, 1002' silently. If I finish counting before reaching that point, it means it's safe. At 100 km/h, this distance is roughly over 50 meters, equivalent to about ten car lengths. Why keep such a distance? Emergency braking on the highway is difficult, and if the road is wet or the car ahead brakes suddenly, a short distance will definitely lead to a rear-end collision. I'm even more cautious in bad weather—during rain or fog, I leave at least a three-second gap. After stabilizing my speed, I make it a habit to frequently check the rearview mirror, avoiding getting too close and causing tension. Safety first is the golden rule; saving time isn't worth it if it leads to an accident.

When driving on the highway at speeds over 100 km/h, I always maintain a safe following distance. I generally use the two-second rule, which is simple and practical: choose a reference point, and after the car in front passes it, I count 'one second, two seconds' to ensure I reach the point within that time. At 100 km/h, this roughly translates to about 55 meters. There are many influencing factors—I increase it to three seconds when the road is wet, and I also extend it if the tires are worn or the vehicle is heavily loaded. I remember one time in the snow when I followed too closely and almost had a collision—a lesson learned the hard way. Safe distance isn’t just a formality; it provides reaction time and braking space to prevent minor incidents from turning into major troubles. Beginners should start practicing at lower speeds to develop good habits. Regularly check the brakes and lights—a well-maintained car brings greater peace of mind.

How often do car tires need to be rotated?

Car tires need to be rotated every 6 to 8 years, with a maximum of up to 10 years. Situations that require tire replacement include: 1. Tires develop cracks; 2. Tires that have been patched more than three times; 3. Severe scratches on the tire sidewall; 4. Severe wear on the tire shoulder or sidewall; 5. Deformed tread or damaged rim; 6. Severe aging and peeling; 7. Tread pattern below the wear indicator; 8. Tire bulging. Methods for removing tires: 1. Loosen the wheel fixing screws by turning counterclockwise (tighten by turning clockwise); 2. After loosening each screw one by one, use a jack to partially lift the vehicle; 3. Once the jack is in place, remove the loosened screws one by one and take off the entire tire to complete the removal.

Is it necessary to replace the fuel pump during a car recall?

Of course, it needs to be replaced. Here is the relevant information: Reason for replacement: The manufacturer's initiative to propose replacing the fuel pump proves that the fuel pump installed in the vehicle model has safety or fault risks. Moreover, the recall for fuel pump replacement does not require the owner to pay a single penny. The fuel pump affects the operation of the vehicle's fuel injection system. Using a fuel pump with potential faults will inevitably impact the vehicle's subsequent use. Therefore, when the 4S shop sends a recall notice, it should be addressed promptly to avoid unnecessary losses in the future. Fuel pump: The fuel pump is a professional term in the automotive parts industry. It is one of the basic components of the fuel injection system in electronically controlled fuel injection vehicles, located inside the vehicle's fuel tank. The fuel pump operates during startup and engine operation. If the engine stops while the ignition switch remains in the ON position, the HFM-SFI control module cuts off the power supply to the fuel pump to prevent accidental ignition.

How to Turn Off the Air Conditioning in a Car?

To turn off the air conditioning in a car, simply adjust the fan speed switch to position 0. If you only want to turn off the cooling function while keeping the fan running, there is usually a separate cooling switch that can be turned off. In winter, if you want the car's air conditioning to provide heat, first switch the cooling/heating toggle to the heating zone, then turn on the fan switch and adjust the speed to the desired level. To turn it off, set the fan speed to 0. Car air conditioning refers to the air conditioning system installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. It generally includes cooling devices, heating devices, and ventilation systems. This integrated system makes full use of the limited space inside the car, featuring a simple structure and easy operation.

What to Do When the Engine Catches Fire?

Methods for handling an engine fire: Park the car in a shaded area, check which part of the car is emitting the burning smell or smoke, then call 119 for emergency assistance. Occupants should use the onboard fire extinguisher for self-rescue. If there is no fire extinguisher or if it is insufficient, clothing, quilts, or other materials can be used to smother the fire. Since most components of a car, such as electrical wiring, tires, and interior decorations, are flammable, priority should be given to addressing these areas. The car engine is the device that provides power to the car, acting as the heart of the vehicle and an energy conversion unit. Its function is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the piston to perform work. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.
