Can a C1 license drive a C5 vehicle under the 2021 new traffic regulations?

Under the 2021 new traffic regulations, a C1 license cannot drive a C5 vehicle. A C1 license only allows driving vehicles with a mass not exceeding 4,500 kilograms, seating no more than 9 people, and with a total length less than 6 meters. On the other hand, a C5 license is a special category established for disabled individuals, allowing them to drive specially modified automatic transmission vehicles. Permitted vehicle types for a C1 license: The scope of a C1 license includes small and mini passenger vehicles, as well as light and mini cargo vehicles; light, small, and mini special-purpose vehicles; and small passenger vehicles seating 9 or fewer people. Vehicles not permitted for a C1 license: Large buses, tractor units, city buses, medium-sized buses, large trucks, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, mopeds, wheeled self-propelled machinery, trolleybuses, and trams. Additionally, a C1 license does not permit driving vehicles with more than 9 seats or trucks with a total length exceeding 6 meters.

What kind of oil should be used for lubricating car sunroof rails?

For lubricating vehicle sunroof rails, it is recommended to use dedicated sunroof rail lubricating oil. Specialized rail lubricating oil generally has three characteristics: 1. Low-temperature resistance, which can effectively prevent freezing; 2. Good water resistance, preventing dilution when washing the car; 3. Strong durability with excellent lubrication performance. Precautions for sunroof use are as follows: 1. The best way to maintain a sunroof is by applying oil. Before oiling, the sunroof rails should be thoroughly cleaned to remove any dust or debris. 2. In winter, especially after snowfall, the sunroof should not be opened immediately as the glass seal may adhere to the surrounding seals. Opening the sunroof may damage the seals, leading to water leakage issues later. 3. When washing the car, high-pressure water jets should not be directed at the seals immediately. This can damage the original viscosity of the seals, allowing water to seep into other areas. 4. If the sunroof makes noise or fails to close, it is often not broken; replacing the rubber seal can usually solve the problem.

What is Chiran No.1 Fuel All About?

It is a combustion improver that enhances the burning efficiency of gasoline. Combustion Improver: Refers to substances that cannot burn themselves but can provide the oxygen required for combustion. In a broad sense, additives used to improve combustion conditions all fall under the category of combustion improvers. Combustion improvers include combustion promoters, slurry dispersants, water separators, ash modifiers, and emulsifiers. Uses of Combustion Improvers: Cleaning Carbon Deposits: Because it contains detergent dispersants, oxygen enhancers, and combustion improvers, it can fully decompose carbon deposits, prevent the formation of sticky substances in the combustion system, and promote complete fuel combustion, thereby reducing engine carbon deposits, ensuring smooth engine operation, and enhancing power performance. The effect is particularly noticeable for older vehicles. Supporting Engine and Fuel System Maintenance: It can compensate for certain deficiencies in fuel properties while adding new characteristics, such as effectively reducing the formation of deposits in the fuel system, cleaning the fuel system, enabling more complete combustion, saving fuel, enhancing engine performance, reducing exhaust emissions, lowering engine noise, and ensuring smooth engine operation, among other benefits.

What are the main components of automotive antifreeze?

The main components of antifreeze are 50% pure water, 40% methanol, and 10% other substances. Functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It possesses excellent properties such as preventing freezing in winter, boiling in summer, and offering year-round protection against scale and corrosion. Antifreeze replacement cycle: For vehicles that operate for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can have a validity period of up to three years. If suspended matter, sediment, or signs of deterioration or discoloration are found in the antifreeze, it should be replaced promptly, and the system should be cleaned. Can different antifreeze brands be mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between the additives, rendering them ineffective.

Where is the child lock on the rear door of the Audi Q5?

Audi Q5's child lock is located on the rear doors, with the switch button positioned on the door armrest of the driver's seat. The driver can press the child lock button to activate or deactivate the child lock. When the child lock function is enabled, the rear doors cannot be opened from the inside but can still be opened from the outside. When the child lock function is disabled, the doors can be opened both from the inside and outside. This feature effectively prevents children from accidentally opening the doors, which could lead to serious consequences. Below is a detailed introduction to the child lock: 1. Almost all vehicles nowadays come standard with a child lock device. When placing children in the rear seats, owners must remember to engage the child safety lock and continuously check during the journey whether the central locking system is in the locked state. Its purpose is to prevent active and unaware children from opening the doors while the vehicle is in motion, thereby avoiding danger. 2. When the car's child lock device is active, even if the electronic central door lock is unlocked, the rear doors remain locked. To open the rear door, one must use the door handle on the outside while the central door lock is in the unlocked state. The mechanical lock of the car consists of an interior handle and an exterior handle, which operate on the principle of two control rods to open the mechanical lock. The child lock's function is to lock the interior handle's control rod.
