What to do if the car is scratched and dented?

The solutions for scratches and dents on the car are as follows: 1. If the scratch is deep, exposing the primer or leaving a deep groove, you need to first apply putty to smooth it out, then apply red putty, followed by spraying primer to check the effect, and finally spray the paint (computer-mixed paint to avoid color difference). This process takes 1-2 hours and yields excellent results, making it impossible to tell that the paint was repaired. 2. If the car is insured, you can directly call the insurance company to report the incident and have them send someone to repair it. The insurance company may also provide free repairs for the vehicle. However, it is crucial to protect the scene and call promptly; if there is no scene, the insurance company may reduce the compensation amount.

How to Determine the Distance Between the Left and Right Corners of the Car Front and Obstacles

Methods to determine the distance between the left and right corners of the car front and obstacles mainly include the following scenarios: 1. If the obstacle is a pedestrian: When you can see the pedestrian's heels, the distance between the car and the pedestrian should be about 4 meters. 2. If you can see the pedestrian's knees: The distance between the car and the pedestrian should be about 2.5 meters. 3. If the obstacle is another car: Focus on the front car's bumper. The rear of a sedan is generally about 42 centimeters from the ground. When you can see the lower edge of the front car's tire, the distance between the front car and your car should be about 4.6 meters.

What are the penalties for forced overtaking?

Forced overtaking is an illegal act and bears full criminal liability according to law. Penalties may include detention, fines, revocation of the motor vehicle driving license, or demerit points. When vehicles are moving in the same lane, the following vehicle should maintain a safe distance from the vehicle ahead to allow for emergency braking measures. Overtaking is prohibited under the following circumstances: 1. The vehicle ahead is making a left turn, turning around, or overtaking; 2. There is a possibility of meeting an oncoming vehicle; 3. The vehicle ahead is a police car, fire truck, ambulance, or engineering rescue vehicle performing emergency tasks; 4. Passing through areas where overtaking is not allowed, such as railway crossings, intersections, narrow bridges, curves, steep slopes, tunnels, pedestrian crossings, and sections of urban roads with heavy traffic.

What to Do When Halogen Headlights Are Not Bright Enough?

There are mainly three methods to address insufficient brightness of halogen headlights. Below are detailed explanations of these three methods: 1. Replace halogen bulbs with LED bulbs: This can solve the problem of dim low beams. However, due to the short wavelength and high color temperature of LEDs, the focal point may deviate from the original halogen bulbs. Directly replacing halogen bulbs with LEDs can easily cause high beams to scatter, resulting in shorter illumination distance and poorer high beam performance. 2. Replace halogen headlights with xenon headlights: Modifying to xenon headlights is a relatively common solution. This requires cutting off the original halogen bulb socket and installing a lens and bulb socket. The color temperature of xenon headlights can be adjusted to adapt to different road conditions. 3. Add a lens to the high beam position based on the LED light setup: This method can solve the scattering issues of both low and high beams, providing better results. However, it requires disassembling the headlight to install the lens.

What is the function of the S gear in a car?

Car S gear is the sports mode of the car. The following are specific introductions about the S gear of the car: 1. In S gear sports mode, the transmission can shift freely: the shift timing is delayed, keeping the engine at high speeds for a longer time, allowing the car to travel at low gears and high speeds for an extended period, achieving greater torque output and acceleration. While the car is moving, simply push the gear lever into the "S" gear, which is typically used for climbing hills and quick overtaking. 2. The main principle of S gear is to make the throttle response faster: the engine speed is also maintained in a higher range, thereby providing high power output. However, when using the S gear, it is necessary to control the speed reasonably to ensure driving safety. 3. The benefits of car S gear: The advantage of S gear is that it can increase the engine load in a short time, which is helpful to some extent in removing carbon deposits from the engine.

Why Do Newly Replaced Brake Pads Make Noise?

Newly replaced brake pads may produce abnormal noises for the following reasons: 1. Check if there are any foreign objects caught between the brake disc and pads. If the noise is a dull sound, it is mostly due to issues with the brake caliper, such as worn guide pins or detached spring plates. If the noise is a high-pitched squeal, there could be multiple problems, including issues with the caliper, brake disc, or brake pads. 2. If the noise persists, first check for any dragging brakes. Poor caliper retraction can cause prolonged friction between the disc and pads, leading to abnormal noises under certain conditions. Also, inspect whether any foreign objects are stuck between the pads and disc. 3. If the pads are new, check if the brake disc has grooves. Localized friction can cause noise. If the disc is fine, consider whether the brake pads are too hard or if the anti-noise shims were installed incorrectly.
