Why do all the front interior lights turn on when the car starts?

When starting the car, the onboard computer performs a self-check. If everything is normal, these lights will turn off after the car starts. The self-check by the onboard computer effectively eliminates potential safety hazards. If any abnormal vehicle conditions are detected, the dashboard will display fault indicators and issues. You can promptly inspect and repair the vehicle based on the displayed icons. The car dashboard displays various icons. Here are some common icons and their meanings: A person with a sword-like symbol indicates that the seatbelt is not fastened during driving. It is important to fasten the seatbelt while driving to significantly enhance personal safety. A snowflake symbol represents the temperature display, indicating -4 degrees Celsius. A teapot dripping water is the oil pressure warning light. When the engine starts, the lubricating oil pressure has not yet built up, so the oil pressure warning light will illuminate for a second. Once the lubricating oil pressure is established, the light will naturally turn off. This phenomenon is more noticeable in winter but is normal and not a cause for concern, so you can continue using the vehicle with confidence. There are many different symbols displayed on the dashboard. When a symbol appears, promptly refer to it to identify the cause. Here are some maintenance tips for car headlights: Replacement: Ensure the car headlights maintain good sealing, especially to prevent dirt and damage to the reflector coating. When replacing bulbs or diffuser glass, avoid touching the mirror surface with your fingers to prevent sweat or oil marks from dulling the reflector and reducing its efficiency. Regular Inspection: Periodically check and adjust the headlight beams to ensure the illumination distance meets requirements and that the high and low beams are aligned correctly. The diffuser glass should be installed properly to prevent loosening or misalignment and to maintain the vertical alignment of the prisms.

What is the engine load rate?

Load rate is a relative percentage concept of torque at a specific engine speed. Its strict definition refers to the ratio of the torque produced at partial throttle opening to the maximum torque produced at wide-open throttle under the same engine speed. Extended information about engine load rate is as follows: 1. When the engine experiences low cylinder pressure: The intake air volume at idle will be higher than normal, the fuel injection volume will also increase accordingly, and the engine load data will rise. When poor engine ignition causes a decrease in engine power, the ECU will compensate by increasing the intake air volume, at which point the engine load data will also show an increasing trend. 2. When there is a vacuum leak downstream of the throttle: It can also lead to an increase in engine load, even though the actual engine load hasn't changed. During vehicle operation, if the power transmission system encounters increased resistance, the additional load will also cause the engine load to rise. For example, when an automatic transmission vehicle experiences a fault with internal stator slippage in the torque converter, since the stator's torque multiplication effect cannot function normally, it will invisibly increase the engine's load, resulting in higher engine load.

Why does the Mercedes key show a red light and fail to lock the car?

Mercedes key showing a red light and failing to lock the car may be due to insufficient battery power or being too far away. Check if the remote key's battery is low: This can be tested by measuring the battery voltage with a multimeter. When the battery is low, the voltage drops, causing unstable performance of the internal circuits, which results in reduced wireless communication range. If the battery isn't too low to power the circuit, you can try locking the car by getting closer to the vehicle. Ensure proximity between the remote key and the car body: Remote keys commonly use either short-range infrared sensing or short-range radio frequency. Regardless of the type, both the transmitting and receiving circuits are prone to malfunctions, which can be attributed to electronic circuit design and components.

How to Fix ETC Malfunction?

You can first check if the OBU fixed on the car's front windshield has fallen off. If it falls off, the anti-tamper button on the back of the OBU will reset, and you will need to go to the ETC card service point for reactivation. Below is a detailed introduction about ETC: 1. Introduction: ETC is the Electronic Toll Collection system, which is an automatic toll collection for highways or bridges. Through dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, it uses computer networking technology for backend settlement processing with banks, thereby achieving the purpose of vehicles passing through highway or bridge toll stations without stopping to pay tolls. 2. Technology: The ETC system uses automatic vehicle identification technology to complete wireless data communication between the vehicle and the toll station, enabling automatic vehicle sensing identification and the exchange of related toll data. It uses computer networks to process toll data, achieving a fully automatic electronic toll collection system without the need for stopping or setting up toll booths.

Does Car Wrapping Require Approval?

If the car is wrapped with transparent film that does not alter the vehicle's color, no approval is required. However, if a color-changing film is applied, altering more than 30% of the vehicle's body color, approval from the vehicle management office is necessary. Additionally, the new color must be one that was originally registered for the vehicle at the time of manufacture. For film wrapping approval, you need to prepare the following documents: the Application Form for Vehicle Modification Registration Approval, the original and a copy of the vehicle owner's identity proof, the vehicle registration certificate, and the original vehicle license. Besides wrapping, the following modifications to a car also require approval: Roof Rack Installation: Vehicles can be fitted with roof racks as long as they do not exceed the specified length. Many SUV models come with factory-installed roof racks, and aftermarket installation is allowed provided the height does not exceed 30 cm. Many vehicles also have pre-installed mounting points on the roof, so it's important to choose a roof rack with a reliable mounting method. However, it's important to note that installing a roof rack requires updating the vehicle's license photo. Running Boards and Bumpers: Running boards and bumpers were previously required to be original equipment. There are no restrictions on running boards as long as they do not extend beyond the vehicle body. However, replacing the front bumper on an off-road vehicle with one that differs from the original requires approval and an update to the vehicle's license photo. Wheels and Grilles: Modifying wheels and front grilles requires approval. Wheel and grille modifications are popular in vehicle customization. While the style and material of the wheels can be changed, modifications must not alter the wheel diameter, width, ET offset, or aspect ratio. Nevertheless, such changes require updating the vehicle's license photo at the local vehicle management office. Brake System: The brake system can be upgraded with different brands of brake calipers and discs from reputable manufacturers. Proper modifications can significantly improve braking performance, but any changes to the brake system require approval.
