Car covers can protect against sunlight. Car covers have multiple functions including being environmentally friendly, waterproof, sandproof, dustproof, frostproof, heat-insulating, cooling, sun protection, and privacy protection. Functions of car covers: Car covers can reduce UV exposure: Car covers are made by manufacturers using specialized sun-protective fabrics, which can effectively block UV rays by reflecting or absorbing them. Car covers can prevent interior aging: In summer, the interior temperature of a car can reach 70-80°C, but with a car cover, the temperature inside the car can be maintained at around 30-40°C, which is more comfortable for humans. Car covers can extend the lifespan of car components: By controlling the temperature, car covers can enhance the durability of car parts. They protect the car paint, windshield wipers, air conditioning system, engine, and other accessories. Precautions for using car covers: Do not use a car cover immediately after parking in summer, as it may affect heat dissipation and reduce the cover's lifespan. For example, aluminum-coated car covers have excellent heat insulation, but using them immediately after parking can trap heat inside the car. In winter, in northern regions, using a car cover immediately after parking may cause ice to form on the hood or damage the cover's lining due to temperature differences between the hood and the cover, leading to condensation. Secure the car cover during strong winds, and avoid using it during typhoons. Car covers usually come with windproof straps, but since they are made of multiple fabric panels stitched together, strong winds from certain angles can damage the cover over time, affecting its reuse.

A car cover really does protect against the sun. As a veteran driver with nearly 20 years of experience, I deeply appreciate its benefits. During the scorching summer sunlight, without a car cover, the car's surface becomes unbearably hot to the touch, and the paint is prone to fading and aging. The reflective car cover I use effectively blocks UV rays, reducing the interior temperature by over ten degrees, so I don’t need to blast the AC as much. It also protects against rain, snow, dust, and bird droppings, preventing corrosion of the car’s paint. The key is to choose a breathable material—otherwise, moisture can accumulate and cause fogging on the windows. I recommend buying a product with UV protection certification; though more expensive, the effects last longer. Over the long term, it not only saves money on car maintenance but also extends the vehicle’s lifespan. Just cover it when parked outdoors—once it becomes a habit, it’s incredibly practical.

Will traffic police check if the wheel size is increased by one inch?

Increasing the wheel size by one inch will not be checked by traffic police, but it will not pass the annual inspection. Changing to a one-inch larger wheel cannot be registered and will also fail the annual inspection. Below are the relevant regulations for vehicle modifications: To modify a motor vehicle: Modifications must be carried out within the scope specified by the traffic management department, such as modifying the body color, engine, fuel type, or frame number. After submitting an application, the driver must obtain approval from the traffic management department before proceeding with the modifications. Unauthorized changes are prohibited: No unit or individual may assemble a motor vehicle or modify the registered structure, construction, or characteristics of a motor vehicle without authorization. Modification actions: Any unauthorized modifications to the chassis, engine, suspension, transmission system, steering system, tires and wheels, lights, body color painting, or exterior structure of a motor vehicle without permission from the public security traffic management department, as well as any technical data of the motor vehicle that does not match the data announced by the State Council's motor vehicle product authority, are considered modification actions.

Is 3.0 bar tire pressure normal?

Tire pressure of 3.0 bar is not normal. For many vehicles, 3.0 bar is a very high value. According to the provisions and requirements of the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: standard tires should be 2.4-2.5 bar; reinforced tires should be 2.8-2.9 bar; while the maximum pressure should not exceed 3.5 bar. The hazards of excessive tire pressure include: reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread pattern, shortening tire lifespan; increased vehicle vibration, indirectly affecting the lifespan of other components; excessive tension on tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; decreased resistance to punctures.

What is the function of the MLC hole in a car?

The "MLC" hole on a car's onboard unit is a simple sound source (speaker) installed inside the unit, primarily used to provide keypress tones during operation or error operation prompts. It is also sometimes used as a Bluetooth voice sound source, which is more common in older models. Nowadays, Bluetooth phone audio can typically be routed to the car's audio system speakers, making it more convenient and clearer for safe driving. Additional information: The "Res" hole on a car's onboard unit is mainly used for recovery or restart purposes, such as when the unit "freezes" during operation; when a "serious error" occurs due to operational mistakes or internal machine issues; as a "special" button during certain onboard unit upgrades; or as a button to restore initial settings when the machine becomes slow due to prolonged use, high memory usage, etc.: releasing memory, restarting, etc.; some special design requirements for certain functions.

What lights should be turned on when driving in foggy conditions for Subject 3?

When driving at night without street lights, under poor illumination, or encountering conditions of reduced visibility such as fog, rain, snow, dust, or hail, motor vehicles should turn on the headlights, position lights, and rear position lights. However, high beams should not be used when following another vehicle closely in the same direction. In foggy conditions, motor vehicles should turn on the fog lights and hazard warning flashers. Additional information: Lighting usage for Subject 3: Turn on the headlights when driving at night without street lights or under poor illumination; use low beams when following another vehicle closely at night; use low beams when meeting non-motorized vehicles on narrow roads or bridges at night; use low beams when meeting other motor vehicles at night; switch from headlights to position lights + hazard warning flashers when a vehicle breaks down or is involved in a traffic accident at night, obstructing traffic and making it difficult to move; use fog lights + hazard warning flashers + headlights when driving in foggy conditions; alternately use high and low beams when passing sharp curves, arched bridges, slopes, crosswalks, or intersections without traffic signal control at night.

Is a fuel consumption of 10 liters per 100 km normal for a new car?

Normal. Factors affecting fuel consumption are as follows: Engine: This is an inherent indicator affecting fuel consumption. From the oldest carburetor to today's direct injection systems, various brands are striving to improve the fuel economy of engines. Purely from a technical perspective, direct injection is an excellent technology that significantly improves fuel combustion efficiency, but it places higher demands on the engine's fuel supply system and cylinder materials. Transmission: Here, the transmission refers to automatic transmissions. The engine and transmission form the simplest power output system, so the structure of the transmission also directly affects fuel consumption. Driving habits: This is an acquired indicator affecting fuel consumption and the most significant factor influencing it. The same car will have different fuel consumption under different road conditions, and whether the air conditioning is used or even when it is turned on can affect fuel consumption.
