Central brake light on is a signal alarm indicating that the high-mounted brake light is not functioning. The brake light is an important light on a vehicle. When the driver presses the brake pedal, the brake light illuminates to alert the driver behind to maintain a safe distance. Below are the introduction of brake lights and the reasons why the brake light stays on: Introduction to brake lights: Brake lights are generally installed at the rear of the vehicle and are red in color to make it easier for vehicles behind to notice when the front vehicle is braking, thereby preventing rear-end collisions. In simple vehicle models, power passes through a fuse to the brake switch. When the brake pedal is pressed for braking, the switch activates, sending electricity to the two brake lights and one high-mounted brake light, completing the circuit through the negative wire connected to the vehicle body. Reasons why the brake light stays on: Lack of brake fluid; Tail light bulb damage; Brake pads need replacement. When braking stops, the return spring restores the brake pads to their original position. If the brake fluid decreases rapidly, it indicates a leak in the brake system.

Can an expired fire extinguisher pass the vehicle inspection?

An expired fire extinguisher can have an impact during the vehicle inspection. If discovered, penalties may be imposed according to relevant regulations. Introduction to Annual Inspection: Motor vehicle inspections include three categories: motor vehicle safety technical inspection, motor vehicle emission inspection, and comprehensive vehicle performance inspection. Annual inspection, also known as annual check, refers to the safety inspection conducted every year or every two years, covering a comprehensive examination of the vehicle's horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, license plate installation, and more. Annual Inspection Process: Upon arrival at the inspection site, the first step is the exterior inspection. The owner needs to park the vehicle in a designated area for exterior checks, prepare the vehicle's fire extinguisher and triangular warning sign, and open the engine compartment and trunk for inspection by the staff. After payment, the owner must submit their ID card and vehicle registration certificate to the staff, who will then enter the vehicle's inspection information into the system. Once these steps are completed, the owner can take the form and wait for the on-line inspection. If the on-line inspection is passed, the owner can proceed to the final procedures at the general inspection office.

Can I Replace the Car If There Are Problems with the New Car's Air Conditioning?

Free repairs and part replacements are available. If it's a quality issue, you can also request a replacement for a new car. Here are some tips for using car air conditioning: 1. Ventilate before turning it on: After the car has been exposed to the sun for a long time, open all four doors and the sunroof to allow air to circulate inside the car for 3 minutes. This quickly lowers the interior temperature, making the air conditioning more effective when turned on. 2. Use the recirculation mode wisely: Recirculation blocks hot outside air, creating a sealed space inside the car where air quickly circulates under the air conditioning to cool down rapidly. Once the interior temperature has dropped, it is recommended to switch to fresh air mode every 30 minutes to purify the air inside the car, then switch back to recirculation after 5 minutes. 3. Turn off the air conditioning in time: Turn off the air conditioning 5 minutes before parking to protect the engine and save fuel.

Why does the car air conditioning cooling fan keep running at high speed?

When the temperature is too high, it operates at high speed, and when the temperature is normal, it operates at low speed for cooling, which is a normal phenomenon. Below is relevant information: 1. Classification: According to the direction of coolant flow in the radiator, radiators can be divided into two types: longitudinal flow and cross flow. According to the structural form of the radiator core, radiators can be divided into tube-fin radiator cores, tube-band radiator cores, and plate-type radiator cores. 2. Material: There are mainly two types of car radiators: aluminum and copper. The former is used for general passenger cars, while the latter is used for large commercial vehicles. The materials and manufacturing technology of car radiators have developed rapidly. While aluminum radiators have gradually replaced copper radiators in the field of cars and light vehicles due to their obvious advantages in material lightweighting, the manufacturing technology and process of copper radiators have made significant progress. Copper brazed radiators have obvious advantages in engine radiators for buses, construction machinery, heavy trucks, etc.

What License is Required to Drive a Non-Standard Vehicle?

Non-standard vehicles require a C3 license to be driven. Introduction to the C3 License: The C3 license is a low-speed truck driving license. According to the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' the C3 license only permits the operation of low-speed trucks and three-wheeled vehicles. It does not authorize the driving of any other vehicle types. The vehicles must be less than 6 meters in length and have a total weight under 4,500 kg. Age Requirement: The C3 license can be obtained by individuals aged 18 to 60. The C1 license covers vehicle types including C1, C2, C3, and C4, making the C3 license quite limited in scope. Relevant Penalties: Four-wheel low-speed trucks with agricultural machinery licenses cannot be driven with a C3 license. In most regions, vehicles with agricultural machinery licenses require an agricultural machinery driving license, which is issued by the Agricultural Machinery Bureau after passing the required tests. Driving agricultural machinery vehicles with a C3 license will be treated as driving without a valid license, resulting in fines, demerit points, and license revocation.

How to Cool Down Overheated New Energy Vehicle Batteries?

1. Reasonable Battery Installation Position From the first electric vehicle to the present, the design of the battery position has undergone several changes. For example, the initial installation was relatively far away, which was safe but resulted in longer cables, increased resistance, rapid cable temperature rise, and significant energy loss. If installed too close, it would be inconvenient for riding. Being too far left or right could also cause many problems during riding, leading to falls or other accidents. 2. Charger with Fan: If using a charger with a fan, always choose an exhaust version and avoid suction-type chargers. A suction-type charger is like buying a vacuum cleaner; over time, accumulated dust can obstruct heat dissipation. It is recommended to use natural cooling chargers. 3. Good Ventilation Environment: Although most batteries are exposed, a significant portion is hidden inside the electric vehicle. If the ventilation and heat dissipation environment for this part is poor, it will lead to inadequate cooling. Poor heat dissipation will inevitably accumulate in the battery compartment, affecting user comfort and battery lifespan. 4. Higher Position is Better Batteries contain water, which is essential for their chemical reactions. Severe water deficiency can affect the electrolytic reaction. Therefore, it is best to install the battery at a higher position. Additionally, batteries must not get wet. If the battery position is too low, it may get soaked during rainy days, leading to battery malfunctions.
