How Soon Can a New Car Be Driven on the Highway?

Is it necessary to go to a 4S shop for maintenance?

Maintenance can be chosen according to your own needs, either at a 4S shop or an external repair shop. The relevant introduction to car maintenance is as follows: Content of minor maintenance: Minor maintenance generally refers to the routine maintenance items performed at the time or mileage specified by the manufacturer to ensure vehicle performance after the car has traveled a certain distance, mainly including oil and oil filter replacement. Interval of minor maintenance: The timing of minor maintenance depends on the effective time or mileage of the oil and oil filter used. The validity periods of mineral oil, semi-synthetic oil, and full synthetic oil vary by brand and grade. Please follow the manufacturer's recommendations.

Do You Need to Turn on AC for Defogging in Winter?

In winter, you don't need to press the AC button for defogging. You can use either cold air or warm air to remove fog from the windshield. Compared to warm air, cold air is less effective, so warm air is generally preferred for defogging, and the AC does not need to be turned on when using warm air. Here’s more about the AC: 1. A/C stands for Air Condition, which refers to air control or air conditioning. In cars, it is understood as the air conditioning cooling switch and also represents the air conditioning compressor. The AC button needs to be pressed when turning on the air conditioning in summer, but it is not necessary in winter. When the air conditioning compressor is activated, the engine's load increases, leading to higher fuel consumption. 2. During winter driving, once the engine's coolant temperature rises, activating the heating function will gradually increase the temperature inside the car. Although the absolute humidity in the space remains unchanged, the high temperature causes water molecules to move vigorously, preventing them from condensing into fog, thus achieving the defogging effect. 3. Therefore, when using cold air for defogging, the AC needs to be turned on, but it is not required when using warm air. 4. In winter, when the heating is on, the heat produced by the air conditioning mainly comes from the coolant, which is used to cool the engine. The engine typically maintains a temperature of around 90 degrees during normal operation, making warm air more effective for defogging in winter.

What Causes Yellow Spots on the Interior Roof Lining of a New Car?

Yellow spots appearing on the interior roof lining of a car may be caused by slight water seepage from the roof. It is necessary to promptly check whether there is any water seepage or leakage on the car roof, and then use glue for thermal bonding to remove the stains. Below are specific methods for dealing with moldy car interiors: Knitted Velvet Interior: First, use a vacuum cleaner to remove dust and mold from the surface of the interior, then clean it with a specialized car interior cleaner. After spraying, the interior can be dried with a blower, or the car can be driven into the sun to dry. Leather Interior: Wipe the interior with a cloth and cleaning agent, then let it air dry naturally. Alternatively, you can turn on the car's heating mode to dry it. Genuine Leather Interior: Genuine leather interiors require regular maintenance. When cleaning, use neutral or alkaline cleaners and avoid using highly irritating mold removers to prevent corrosion of the interior. After cleaning, let it air dry naturally (avoid exposing the car to direct sunlight).

How Many Chips Does a Car Need?

Traditional cars typically require around 500-600 chips. With the addition of features like autonomous driving and new energy technologies, the number of chips in modern cars has increased to approximately 1,000-1,200. Some models that emphasize intelligent features may require even more chips. Relevant information is as follows: Classification of automotive chips: Based on functionality, automotive chips can be broadly divided into three categories. The first category is responsible for computing and processing, such as AI chips used for autonomous driving perception and fusion, and traditional MCUs (Electronic Control Units) for engine/chassis/body control. The second category handles power conversion, including power devices like IGBTs (Insulated Gate Bipolar Transistors). The third category consists of sensor chips, used for various radars in autonomous driving, as well as for airbags, tire pressure monitoring, etc.

What Causes the Steering Wheel to Not Return to Center Properly?

Steering wheel not returning to center properly can be caused by inaccurate camber or toe angles. Below are specific details about the steering wheel: Reasons for improper return: Damaged outer steering gear or over-tightened free play adjustment bolt of the steering gear; inaccurate camber or toe angles; damaged suspension bushings, causing severe inner tire wear. Function: Converts the force applied by the driver on the steering wheel rim into torque, which is then transmitted to the steering shaft. Precautions for using the steering wheel: Avoid excessive force when turning the steering wheel, and refrain from sudden jerky movements. Do not turn the steering wheel when the vehicle is stationary; on bumpy roads, hold the steering wheel firmly with both hands to prevent loss of control and potential accidents; reduce speed when turning; gradually turn the steering wheel according to the curve's radius when entering a bend.
