How often should a vehicle be started if it is not used for a long time?

If a vehicle is not used for a long time, it should be started once a week. If idling without driving, it is recommended to idle for ten minutes and then rev the engine for two minutes. When a vehicle is not used for a long time, protective measures should be taken to avoid difficulties in starting the car. For long-term parking, it is advisable to directly disconnect the negative terminal of the battery to reduce power consumption. Protective measures for vehicles not used for a long time: 1. Park the vehicle on a flat surface to avoid tire compression and wear of internal oils, which may cause imbalance and malfunction; 2. If parked for an extended period, remove the vehicle battery to prevent prolonged discharge; 3. If necessary, park the vehicle in a garage to prevent damage to the paint surface.

Is Soundproofing Necessary for Cars?

Soundproofing is not mandatory for cars. Automotive soundproofing can be categorized into partial and full-vehicle soundproofing. Some vehicles already have decent sound insulation, or only certain areas lack proper insulation. In such cases, full-vehicle soundproofing isn't necessary—targeted soundproofing in specific areas can yield significant improvements. Car noises are classified into low, medium, and high frequencies, and not all noises can be effectively blocked. For instance, engine noise and sheet metal vibrations, which fall under medium-to-high frequencies, can be mitigated with soundproofing. However, noises like tire roar, especially exhaust pipe sounds, which belong to medium-to-low frequencies, are often challenging to block.

Does uneven tire pressure among four tires affect driving?

Uneven tire pressure among four tires does affect driving. Different tire pressures result in varying rolling resistances for each tire. Particularly, if the tire pressures on both sides of the same axle are unequal, it can easily cause the vehicle to pull to one side while driving. Additionally, it may lead to heavier steering and reduced driving stability. The normal tire pressure range is between 2.2 and 2.5. Excessive tire pressure concentrates the vehicle's weight on the center of the tread, causing rapid wear in that area. Conversely, insufficient tire pressure can lead to uneven contact area, increased wear, higher rolling resistance, and increased fuel consumption. Therefore, maintaining proper tire pressure is crucial for driving safety, tire lifespan, and optimal performance.

How Often Should a New Car Be Inspected?

New cars have different inspection requirements depending on the vehicle type. For ordinary family cars, new vehicles must undergo an inspection every two years, while passenger transport vehicles must be inspected annually within the first five years. Vehicle inspection is a mandatory test for all motor vehicles that have obtained official license plates and registration certificates. It is similar to an annual safety check-up based on the technical safety requirements for motor vehicle operation. The purpose is to promptly eliminate potential safety hazards, encourage and enhance vehicle maintenance, and reduce the occurrence of traffic accidents. The inspection primarily focuses on the vehicle's safety, including a comprehensive check of components such as the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, and license plate installation.

What to Do When the Sunroof Switch Fails?

Solutions for a malfunctioning sunroof switch: After removing the cover clips, take out the faulty switch controller, replace it with a new one, and then secure the cover back in place. If there is insufficient lubrication, the resistance becomes too great, causing the sunroof to activate the automatic anti-pinch feature, which results in the sunroof being able to open but not close. The sunroof mainly consists of a glass panel, sealing rubber strips, and a driving mechanism. The opening styles of sunroofs are generally categorized into external sliding panel, internal sliding panel, and tilting types. The external sliding panel type features a glass panel that slides above the roof panel; the internal sliding panel type has a glass panel that slides between the roof panel and the interior headliner; the tilting type allows the front or rear end of the glass panel to tilt upward for opening. Currently, the latter two styles are more commonly used.
