Laws and regulations impose restrictions on car modifications. The vehicle model, engine model, and chassis number cannot be altered, and the body structure must not be compromised. If the car's color is changed, or the engine, body, or chassis is replaced, the vehicle must be inspected. Additionally, replacing the engine, body, or chassis requires submitting a valid motor vehicle safety inspection certificate. Decals or stickers must not cover more than 30% of the total body area. However, there are cases where car modifications are not illegal. Changing the car's color: It is permissible to change the car's color, but avoid using camouflage patterns, fire engine red, emergency vehicle yellow, or law enforcement's white-and-blue scheme. Most importantly, remember to complete the modification registration at the vehicle management office within ten days and obtain a new driving license. For those who wish to add decals, ensure the coverage does not exceed 30% of the car's body area. Important notes: In principle, modifications are allowed as long as they do not affect driving safety. However, seats cannot be removed, the interior structure must remain unchanged, and any structural features registered with the vehicle management office must not be altered without authorization.

How to Confirm if the Handbrake Relay Valve is Faulty?

Relay valve damage typically results in slow brake release. In the braking system of heavy-duty vehicles, the relay valve serves to reduce reaction time and pressure build-up time. The relay valve is part of the vehicle's air brake system, and severe cases may even lead to wheel lock-up.

How to Tell if a Traffic Light Captures Running Red Lights?

During driving, if you have GPS or mobile navigation turned on, it will alert the driver about how many meters ahead there will be traffic violation cameras when approaching a traffic light. Additionally, you can also determine by observing whether there are concealed cameras around the intersection.

Is the Outlander's Vehicle Stability Control System Light On Indicating It's Turned Off or On?

When the Outlander's Vehicle Stability Control (VSC) system light is on, it indicates that the system is turned off. Below are situations where the ESP (Electronic Stability Program) needs to be turned off: When the vehicle is stuck in mud or sand during off-roading: If the vehicle is trying to climb out of mud, there may be a significant difference in wheel speed between the two sides. In this case, if the ESP is active, the engine torque will be continuously consumed by the wheel with less rolling resistance, and the ESP will limit the engine RPM. Even if you press the accelerator hard, it may be difficult to get out of the situation. Turning off the ESP at this time will make it easier to escape. When aggressive driving is desired: During drifting, there will be a large difference in wheel speed between the left and right wheels. If the ESP intervenes, it will be difficult to achieve an aggressive driving experience. Turning off the ESP will make it easier to perform impressive maneuvers. When snow chains are installed on the vehicle: For vehicles equipped with snow chains, detection signals such as those from wheel speed sensors and lateral acceleration sensors may become inaccurate. This can affect the normal operation of the ESP system, causing it to intervene continuously or trigger fault codes.

How to resolve the driving system malfunction in Audi A4L?

When the brake pads with wear sensors reach their limit, the sensor wire automatically completes the circuit, triggering the warning light. Low brake fluid level will also be accompanied by significantly reduced braking force, and in severe cases, complete loss of braking power may occur.

What is the Function of an Automotive Air Suspension System?

Introduction to the functions of an automotive air suspension system: 1. Control the damping force of the shock absorber: The air suspension system collects signals from sensors such as the vehicle speed sensor, steering angle sensor, and body height sensor. After processing by the suspension ECU, it controls electromagnetic or stepper motor actuators to adjust the damping force of the shock absorber. During sharp turns, rapid acceleration, or emergency braking, it suppresses vehicle "squat," "dive," and roll, preventing excessive changes in vehicle posture, thereby improving handling stability. 2. Adjust the stiffness of the elastic element: The air suspension system adjusts the stiffness of the shock absorber by changing its elastic coefficient, allowing the vehicle to freely choose between sport mode or comfort mode based on actual driving needs. 3. Adjust the vehicle height: One of the main functions of the air suspension system is to maintain the vehicle height within a reasonable range under various operating conditions. If the vehicle remains too high off the ground for an extended period, driving will feel very bumpy, as if no shock absorbers are installed. If the vehicle is too close to the ground, the lower part of the chassis may easily collide with uneven surfaces, or even render the vehicle undrivable. The electronically controlled air suspension system automatically compresses or extends the air springs by controlling the air compressor, height control valve, and exhaust valve, thereby reducing or increasing the ground clearance of the chassis to maintain the vehicle at an appropriate height.
