Can a Vehicle Pass the Annual Inspection with the Airbag Light On?

If the airbag warning light remains illuminated, the vehicle will not pass the annual inspection. Here is some additional information: 1. The vehicle submitted for inspection should be clean, with no obvious oil, water, or air leaks. The tires should be in good condition, with normal tire pressure and no foreign objects in the tread pattern. 2. The engine should run smoothly, with stable idle speed and no abnormal noises. 3. For vehicles equipped with an onboard diagnostic system, there should be no fault information related to the anti-lock braking system, electric power steering system, or any other safety-related systems. 4. During the vehicle inspection, the vehicle's registration certificate and a valid compulsory traffic accident liability insurance certificate must be provided.

What does EV mode mean in cars?

EV in cars represents the electric mode in vehicle modes, which generally only appears in hybrid vehicles. Here are the specific details: 1. EV is the abbreviation for Electric Vehicle, which refers to vehicles that use on-board power as the driving force, use motors to drive the wheels, and meet all the requirements of road traffic and safety regulations. 2. When the vehicle's battery is insufficient, the engine will automatically start to drive the vehicle while also charging the battery. Once the vehicle's battery reaches a usable level, the engine will automatically shut off, and the vehicle will continue to operate in pure electric mode.

Is It Normal for Water to Drip Under the Car?

Water dripping under the car is a normal phenomenon, as detailed below: 1. Air conditioning system drainage. Due to the high outdoor temperature in summer and the low temperature inside a car with the air conditioning on, a temperature difference forms, causing water to drip from the chassis. The low-pressure lines of the car's air conditioning system are not wrapped with thermal insulation foam, making the surface of the lines prone to condensing moisture from the air. Water droplets will also condense and gather at the lowest point of the lines, dripping down. This is a normal phenomenon. 2. Water dripping from the muffler and exhaust pipe at the rear of the car is also normal, commonly occurring in winter. Gasoline is injected into the cylinders and mixed with air, and after complete combustion in the combustion chamber, it mainly produces carbon dioxide and water. At high temperatures, water is discharged into the atmosphere as gaseous water vapor. Since the muffler is located at the rear of the car where the temperature is relatively low, the water vapor condenses into liquid water when it cools.

How to Operate One-Touch Power Windows?

One-touch power windows can be controlled either through the window button or the smart key switch. Below is additional information: 1. Mid-to-high-end vehicle models are equipped with one-touch power window functionality, providing convenience for drivers and passengers while avoiding distractions caused by manually operating windows, thereby enhancing safety. 2. One-touch power windows feature an "anti-pinch" function to prevent hand injuries. The driver's side is equipped with one-touch operation primarily for safety considerations. 3. Standard power windows require holding the switch until the window reaches the desired position, at which point releasing the button stops the movement. Vehicles with one-touch power windows have a two-stage window control switch: the first position functions like a standard power window, while the second position allows automatic full opening or closing with a single press and release.

Do You Need to Add Antifreeze in Summer?

You need to add antifreeze in summer. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. Composition of Antifreeze: The main components of antifreeze are: 50% pure water, 40% methanol, and 10% other substances. Types of Antifreeze: Antifreeze is generally divided into three types: ethanol-water, glycerol-water, and ethylene glycol-water. Can Different Antifreeze Brands Be Mixed? You must use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could cause chemical reactions between additives, rendering them ineffective. How to Choose Antifreeze: The basic indicators of antifreeze are freezing point and boiling point. The market offers antifreeze with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region.

How to Turn on the Car Defroster?

Car defroster switch: The front windshield defroster is represented by a fan-shaped pattern with three upward lines, and the rear windshield defroster is represented by a rectangular pattern with three upward lines. Press the corresponding button to activate it. Below is an introduction to the defroster: 1. The function of the defroster is to capture mist particles and slurry droplets carried by the flue gas during the spray absorption process. 2. The defroster mainly consists of plates and a support device. The plates are usually made of two types of materials: polymer materials (such as polypropylene PP, FRP, etc.) or stainless steel (such as 316L, 317L, etc.). They are generally divided into streamlined and folded types.
