Car spoiler modifications must not exceed 300mm. Below is an introduction regarding illegal modifications: 1. Penalties: Driving an illegally modified vehicle on public roads will result in the vehicle being impounded by traffic authorities, confiscation of illegal modifications, orders to restore the vehicle to its original condition, and legal fines. 2. Regulations: Vehicles with illegal modifications will not be issued a safety inspection compliance certificate by traffic authorities. If the modifications constitute a violation of public security management laws, public security authorities may impose fines, detention, or other penalties in accordance with the "Public Security Administration Punishment Law." When modifying your vehicle, it is essential to apply for a modification registration with the traffic management department of the public security authorities to ensure the vehicle can pass annual inspections and routine safety checks after modification.

What is the purpose of an active grille shutter?

The function of an active grille shutter is to achieve shorter warm-up time and lower drag coefficient. Below are the advantages of an active grille shutter: 1. Shorter warm-up time: Regarding warm-up, there should be a consensus that a vehicle can only reach its optimal state after the coolant reaches the appropriate operating temperature. This is where the advantage of an active grille shutter comes into play: after starting the vehicle, the active grille shutter automatically adjusts its opening based on the engine temperature, thereby achieving faster warm-up. 2. Lower drag coefficient: If the windows are opened too wide, strong wind resistance can become a burden on the vehicle. As the "window" of the engine compartment, the active grille shutter, when closed at the right time (for example, in the ATS-L, when the speed exceeds 60km/h, the onboard computer automatically monitors the engine temperature and closes the grille when no additional air cooling is needed), can also provide the vehicle with a lower drag coefficient, thereby improving vehicle stability and fuel economy.

Why is there a continuous sound of the car door locking and unlocking?

During driving, the repeated sound of the car door locking is because the car automatically locks when reaching a certain speed, and if the door is not properly closed or there is an issue with the lock, it will repeatedly lock. After automatic locking, there may often be multiple consecutive locking sounds. It could also be due to a loose linkage inside the door lock, preventing the electric lock from engaging properly, which easily results in the door not being securely locked and requires maintenance and inspection. More relevant information is as follows: 1. GEM controls various functions of the central locking: Each of the four doors has a door module, and each door lock motor is controlled by its own door module. The door control units are connected to the body control unit GEM via a medium-speed CAN network line for signal transmission. The GEM controls various central locking functions, such as remote unlocking and automatic locking when the speed exceeds 7 km/h. The front door locks have the function to control the locking and unlocking of all doors. 2. Replacing the door lock assembly: Since the door lock signal switch and the door lock motor are integrated into the door lock assembly, only the entire door lock assembly can be replaced.

What Causes the Abnormal Noise from Newly Replaced Tires?

After replacing new tires, if you notice abnormal noises, the following possibilities may exist: 1. During the tire replacement process, it's possible that the bearings were damaged. 2. If you replaced the tires yourself or the maintenance personnel did not perform a proper four-wheel alignment after replacement, it could lead to uneven force distribution among the tires, resulting in "tire cupping." 3. The newly replaced tires have a low aspect ratio or increased width, which will increase noise levels, depending on the owner's preference. Generally, there are several reasons for excessive tire noise: 1. The first possibility is that foreign objects may be stuck in the tire treads, which can be checked and removed. 2. The second reason could be excessively high tire pressure or uneven tire pressure among the tires, which requires confirmation at a repair shop. 3. The third possibility is that after replacing new tires or not having a four-wheel alignment for an extended period, uneven tire wear may occur.

What to Do If 6 Points Are Deducted During the Probationary Period of a Driver's License?

C1 driver's license during the probationary period with 6 points deducted will not affect the probationary license. As long as you promptly handle the traffic violation, pay the fine, the points will be cleared at the end of the scoring cycle. Below are the regulations for traffic violation point deductions: 1. Situations resulting in a 6-point deduction: Driving a motor vehicle during the period when the motor vehicle driver's license is revoked; driving a motor vehicle in violation of traffic signals; driving a commercial passenger vehicle (excluding buses), school bus with 20% or more passengers, or other passenger vehicles with 20% or more passengers; driving medium-sized or larger passenger vehicles, school buses, or hazardous goods transport vehicles on highways or urban expressways at speeds exceeding the prescribed limit by 20% or more; driving medium-sized or larger passenger vehicles, school buses, or hazardous goods transport vehicles on roads outside highways or urban expressways, or driving other motor vehicles at speeds exceeding the prescribed limit by 20% but less than 50%. 2. Consequences of accumulating 12 points: If 12 or more points are accumulated within the 12-month probationary period, your driver's license will be revoked, requiring you to reapply for driving school and obtain a new license. Any illegal activities will be dealt with according to relevant legal provisions.

Is it necessary to rotate the front and rear tires of a sedan?

It is necessary to rotate the front and rear tires of a car. To achieve optimal tire wear, tire rotation is essential. The reasons for rotation are as follows: 1. Rotating the front and rear tires helps prevent uneven wear over time, extending the overall lifespan of the tires and ensuring driving safety. 2. This is particularly relevant for models with less precise chassis data. For vehicles with highly accurate chassis alignment data, rotating the front and rear tires can have drawbacks, primarily affecting the chassis data and causing the vehicle to pull to one side.

How to Solve the Problem of Loud Tire Noise in Civic?

Tire noise is too loud should check the tire tread, whether it is uneven wear. Here are the specific methods: 1. If there is uneven wear, it is a problem with wheel alignment, realign the wheels. 2. If there is no uneven wear but the noise is still loud, replace with new tires. 3. Do sound insulation for the wheel arches, you can use quiet tires, the noise will be reduced. Tire noise: usually caused by uneven tire wear with bumps and grooves producing noise (check if there are obvious bumps or uneven wear on the tires), or poor body sound insulation allowing tire noise to enter the cabin (usually caused by small stones being thrown up by the tires rolling against the inner fender, replacing the inner fender with one that has soft padding can reduce the noise).
