Vehicles exempt from inspection within six years include: non-commercial passenger cars, other small vehicles, and mini passenger cars. The six-year exemption means that these vehicles are exempt from on-site inspection within six years and can directly apply for inspection stickers from relevant departments. However, owners must still provide proof of compulsory traffic insurance, vehicle and vessel tax payment or exemption every two years. For vehicles exempt from inspection within six years, the following points should be noted during annual inspection: 1. Collect the annual inspection sticker: Go to the vehicle management office to collect the annual inspection sticker within the specified period. 2.

What are the common causes of non-functioning fog lights on a Tiggo 3?

Common causes of non-functioning fog lights on a Tiggo 3 include a faulty fog light switch, damaged fog light bulbs, or a blown fuse. The purpose of fog lights is to enhance vehicle visibility during foggy or rainy conditions when visibility is significantly reduced due to weather. Therefore, fog lights require light sources with strong penetration capabilities. Most vehicles use halogen fog lights, while more advanced models may feature LED fog lights. Here is a classification of automotive lighting: 1. Headlights: Combination headlights are located at the front of the vehicle and primarily serve illumination and signaling purposes. The light emitted by headlights illuminates the road ahead, enabling safe nighttime driving. 2. Combination taillights: Combination taillights are positioned at the rear of the vehicle and mainly function for illumination and signaling. 3. Turn signals: These lights indicate left or right turns to other road users. Regulations typically require them to be amber in color. 4. License plate lights: License plate lights primarily illuminate the vehicle's license plate, allowing identification of the license plate in dark conditions.

What Causes Abnormal Noise Due to Excessive Clearance in the Brake Caliper?

Abnormal noise due to excessive clearance in the brake caliper may be caused by loosening or corrosion of the caliper guide pins. Replacing and lubricating them with grease can resolve the issue. It could also be the sound of the brake pads hitting the caliper. Additionally, if there are foreign objects between the caliper and the brake disc, abnormal noise may occur. It is best to diagnose the specific cause at a repair shop. Below is an extended introduction: 1. Brake Caliper Concept: The brake system consists of a master cylinder and brake calipers. Simply put, the master cylinder stores brake fluid and has inlet and outlet ports. When the brake pedal is pressed, the brake fluid flows from the master cylinder through the pipes to the brake calipers. When the calipers are pressurized, they push the brake pads, causing them to rub against the brake drum, thereby achieving braking. 2. Symptoms of a Faulty Brake Caliper: Oil leakage at the connection between the caliper and the oil pipe, and a soft feeling when pressing the brake pedal; noticeable steering wheel pull to one side after pressing the brake pedal, which is likely caused by uneven brake pad wear or caliper malfunction; the brake pedal does not rise or offer resistance after being pressed, commonly referred to as brake pedal not returning.

What Causes the Auto Start-Stop Function to Stop Working?

Here is a detailed explanation of the reasons why a car's auto start-stop function may stop working: 1. Accidental Press of the Start-Stop Button: Vehicles equipped with auto start-stop typically have the system enabled by default. If it suddenly stops working, it might be due to accidentally pressing the auto start-stop button, which turns the system off. 2. Complex Activation Conditions for Manual Transmission Cars: The auto start-stop function in manual transmission cars has more complex activation conditions. The system will only engage when it detects three actions: shifting to neutral, engaging the handbrake, and releasing the clutch. 3. Different Designs Across Brands and Models: The auto start-stop system varies by brand and model. For example, the system in the New Passat requires specific conditions to be met, such as fastening the seatbelt, closing the left front door, and then starting the engine. 4. Other Reasons: The function will not activate under the following conditions: the engine has not reached normal operating temperature, the auto air conditioning has not reached the preset temperature, the battery charge is insufficient, the steering wheel is turned after stopping, the vehicle undergoes emergency braking, or when reversing. 5. Auto Start-Stop System Malfunction: The system may fail due to wiring issues or other reasons. In such cases, it is best to have the vehicle inspected at a 4S shop.

Does a Flashing Red Dot on the Car Key Indicate Low Battery?

When the red dot on your car key flashes, it typically indicates that the battery is low and needs to be replaced promptly. Here's how to replace the car key battery: Open the back cover of the key, then remove the small protective cover over the internal battery. Take out the old battery, insert a new one, and close the back cover to complete the replacement. Besides a depleted battery, other possible causes for the flashing red dot include a malfunctioning time control module in the remote key or aging of the vehicle's remote transmitter antenna. If the key still doesn't work properly after replacing the battery, it's advisable to check for other issues. However, it's not recommended to attempt these checks yourself; instead, visit a 4S shop for professional diagnosis and repair. If the car key is completely dead and lacks sufficient power to function, you can use the spare mechanical key. Simply follow the instructions in the manual to remove the mechanical key, which will allow you to unlock the car door. However, this is only a temporary solution, and you should replace the battery as soon as possible. When using a smart remote key, avoid exposing it to strong magnetic fields, such as those near high-voltage power lines or transmission towers, as these can interfere with the key's operation. Smart keys use low-intensity radio waves, which may fail to function properly under magnetic interference. Additionally, avoid dropping or throwing the key, as this can cause poor battery contact inside the key.
