How to Operate BMW Automatic Transmission?

How long can you drive with tire pressure below 200?

A tire pressure of 200 is too low, and driving long distances under such conditions can harm the tires. It's best to adjust to the normal tire pressure before driving. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening its lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends and deforms the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass, the tire is more prone to punctures, leading to internal cracks, blowouts, and potential tire bursts. Hazards of insufficient tire pressure: Increases friction with the road surface, raising fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement in various parts of the tire, leading to abnormal overheating due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, resulting in damage and abnormal wear; Multiplies friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire bursts; Increases tire deformation, making the sidewalls prone to cracks and generating excessive heat due to flexing, accelerating rubber aging, cord fatigue, and breakage, while also enlarging the tire's contact area and speeding up shoulder wear.

What documents are required for second-hand vehicle transfer?

The required documents are as follows: The original owner of the second-hand vehicle needs to provide documents including the registration certificate, vehicle license, and ID card. The buyer needs to provide an ID card, and if they are from another city, a residence permit or temporary residence permit is required. For companies or organizations, the original and photocopy of the organization code certificate and the official seal are needed. The original owner's commercial insurance can be canceled (compulsory insurance cannot be canceled), or the insurance can be transferred to the buyer at the insurance company. According to Article 19 of the "Motor Vehicle Registration Regulations," when applying for transfer registration, the current motor vehicle owner must fill out an application form, inspect the vehicle, and submit the following documents and proofs: Identity proof of the current motor vehicle owner. Proof and documents of motor vehicle ownership transfer. Motor vehicle registration certificate. Motor vehicle license. For motor vehicles under customs supervision, the "Customs Supervision Vehicle Deregistration Certificate" or a customs-approved transfer certificate must also be submitted. For motor vehicles that have exceeded the inspection validity period, a motor vehicle safety technical inspection certificate and a compulsory traffic accident liability insurance certificate must also be submitted. Precautions when buying a second-hand vehicle: Incomplete documents. Complete second-hand vehicle documents include: vehicle registration certificate (or original purchase invoice), vehicle license, vehicle purchase tax payment certificate, road maintenance fee documents, and compulsory insurance. Missing vehicle registration certificates, vehicle licenses, or unpaid compulsory insurance and road maintenance fees can cause endless trouble for the buyer. Tampering with the odometer. Most consumers judge a vehicle's condition by the odometer, and sellers often take advantage of this by tampering with it. The odometer is not just a record of usage intensity but also a log for the maintenance and replacement of other vehicle parts. If buyers follow the tampered odometer for maintenance, it can lead to a series of potential safety hazards. New paint covering "external injuries." When consumers buy a second-hand vehicle, if the car has been repainted and there are signs of repairs around the front, rear, and A, B, C pillars, the vehicle may have been involved in a major accident. "Tuning the heart" to raise the price. Many consumers focus too much on the car's "heart" (engine) and neglect the health of the car body. Second-hand car sellers take advantage of this by replacing engine parts to make the vehicle's "heart" appear younger, thereby inflating the price.

How Long Does the Paint from a 4S Shop Last?

4S shop paint job longevity depends on paint quality and workmanship. With high-quality materials and proper application, the paint can typically last 4-5 years. Automotive paint thickness standards range between 120 to 180 microns, consisting of four layers: electrocoat primer, mid-coat, base color coat, and clear coat. Key functions of automotive paint include: 1. Protecting vehicles from atmospheric corrosion. 2. Enhancing vehicle aesthetics. 3. Identifying vehicle categories. 4. Improving comfort and sealing while reducing vibration noise.

What Are the Signs of a Dead Car Battery?

Dimming vehicle lights, weak horn sound, and sluggish engine start are all signs of a dead car battery. Methods to deal with a dead car battery: 1. Jump-start: Since the vehicle itself is a platform that uses electricity while charging, a dead battery can be jump-started to recharge. After jump-starting, driving for two to three hours under normal conditions can restore the battery's charge. 2. Charger charging: For vehicles that have been parked for a long time, using a charger to restore the battery's charge is a good method. However, it's important to note that charger operation requires caution, as improper operation may damage the battery.

Differences between Class C and Class F Refrigerated Trucks

The differences between Class C and Class F refrigerated trucks are as follows: 1. Temperature: Class C refers to refrigerated trucks where the average internal temperature is generally between 12°C and -20°C when the ambient temperature is 30°C. They are typically used for transporting vegetables and fruits, which require relatively precise temperature control, thus demanding considerable experience and skill from the operators. Class F refers to refrigerated trucks where the average internal temperature is generally below or equal to -20°C when the ambient temperature is 30°C. They are commonly used for transporting frozen meat, seafood, frozen foods, etc. These goods generally do not require strict temperature control as long as the temperature remains below -18°C.

Are the Batteries Exchanged for Old Ones Refurbished Batteries?

Battery is refurbished. Here is the relevant content introduction: Battery refurbishment: Battery refurbishment has formed a complete industrial chain. After processes such as water replenishment, desulfurization, softening repair, opening the case to replace plates, capacity restoration, and polishing, a set of scrapped old batteries can be transformed into a set of brand-new batteries. Regular manufacturers: Generally, when purchasing batteries from regular manufacturers, the products are bought at the price of new ones, with a 15-month warranty period. If you buy refurbished batteries from small workshops, the quality is not guaranteed, and the service life is very short. The value of the exchanged old battery is about one-third of that of a new battery.
