What documents and procedures are required for a new car?

There should be the vehicle registration certificate, vehicle license, vehicle purchase tax payment certificate, annual inspection compliance sticker, green environmental protection sticker, and compulsory traffic insurance sticker. Below is relevant information: 1. Vehicle License: The vehicle license is the most important document. Once license plates are obtained and the car is on the road, the vehicle license must be present and carried with the vehicle at all times. Compulsory traffic insurance is also mandatory for vehicles on the road and must be prominently displayed on the front windshield. The vehicle compliance certificate, which proves the vehicle is free from defects or safety issues, must also be prominently displayed on the front windshield. 2. Buying a Car on Loan: If the car is purchased through a loan or installment plan, the purchase invoice and the vehicle registration certificate must be mortgaged to the bank. Only after the loan is fully repaid and a loan clearance certificate is obtained from the bank can these documents be retrieved. Additionally, the vehicle registration certificate and purchase invoice are required when completing the vehicle release procedures after the loan is repaid.

What are the reasons for the slow inflation of a newly replaced air pump?

Reasons for the slow inflation of a newly replaced air pump: Spiral impeller: Check if the spiral impeller is installed in the wrong direction. Air pipe, motor, and impeller: Also, check if there are any issues with the air pipe below the air pump, the motor, and the surrounding area of the impeller. Motor coil: The motor coil is damaged, or the air pump diaphragm is damaged. Air pump: The motor of the air pump is damaged; whether the air pump belt is too loose; the air pump intake filter is dirty and clogged. Exhaust valve: The steel plate of the intake and exhaust valves is worn, causing poor sealing. Piston: The piston rings are misaligned or worn; the cylinder piston or cylinder liner is worn or out of round. This can determine that the fault lies between the air pump and the air storage cylinder.

What is the fuel consumption per 100 kilometers for the Focus?

The urban fuel consumption (with air conditioning on) for the Focus is 8.6L/100KM, while on the highway it is 7.7L/100KM at speeds around 70–100KM. Relevant details are as follows: 1. Powertrain: The Focus is equipped with two engine options: 1.0T and 1.5T. Compared to the previous model, the new version emphasizes the application of small-displacement turbocharged engines. In addition to the 1.6L naturally aspirated engine, it also features 1.0T and 1.5T engines. 2. Body dimensions: The Focus has a length of 4534 mm, a width of 1823 mm, a height of 1483 mm, and a wheelbase of 2648 mm. The new Focus retains the body dimensions of the current model while increasing the internal lateral space.

Can Temporary License Plates Be Insured?

Before obtaining a license plate, it is mandatory to pay for compulsory traffic insurance. Without this insurance, the vehicle inspection and registration process cannot be completed. Here is some relevant information about temporary license plates: Concept: Temporary license plates are paper-based vehicle plates that allow a vehicle to be driven on the road temporarily. They are issued by the vehicle management department of the public security bureau for newly purchased vehicles before official registration. The validity period of a temporary license plate generally does not exceed thirty days. Classification: There are four types: temporary license plates for administrative jurisdictions, temporary license plates for cross-administrative jurisdictions, temporary license plates for testing purposes, and temporary license plates for special-type motor vehicles. Driving a newly purchased car to apply for a temporary license plate, only to be stopped by traffic police midway and penalized with 12 points.

What kind of engine oil is usually provided in manufacturer-sent maintenance?

Manufacturer-sent maintenance usually provides semi-synthetic engine oil. Full synthetic engine oil has low evaporation loss: Synthetic oil is generally a pure compound with a narrow boiling point range, and its evaporation loss is much lower than that of mineral oil, which can reduce fuel consumption, reduce exhaust emissions, and extend the service life of the catalytic converter. In addition, compared with traditional mineral oil-type engine oil, synthetic oil also has excellent chemical stability, good radiation resistance, high oil film strength, and low foam characteristics. Therefore, high-end cars generally choose synthetic oil. Full synthetic engine oil has strong high-temperature oxidation resistance: The thermal oxidation stability of synthetic oil is much better than that of mineral oil-type engine oil, meaning it has a lower tendency to produce acidic substances and sludge due to oxidation. Under various harsh operating conditions, it can provide appropriate lubrication and effective protection for the engine, thus having a longer service life and ensuring the stability of the oil's performance over long-term use. In the same working environment, synthetic oil has a much longer service life than mineral oil, so although the cost is higher, when comparing the number of oil changes, it is not much higher than mineral oil.

What is the steering wheel rotation range?

Steering wheel rotation range: One full turn of the steering wheel is 360 degrees. Correct hand positions for steering: One full turn of the steering wheel equals 360 degrees, while a quarter turn equals 90 degrees. You can visualize the steering wheel as a clock face—the proper hand positions are left hand at approximately the 9 o'clock position and right hand at the 3 o'clock position. To turn 90 degrees after a full rotation, simply turn the wheel one full turn plus an additional quarter turn. Steering techniques: When practicing steering, beginners don't need to overanalyze the exact degree of rotation. Just follow the principle: 'Turn as much as needed, return as much as turned; small turns require small returns, slow turns require slow returns, large turns require large returns, and quick turns require quick returns.' As for determining how much to turn, you can use the steering wheel markings as reference or simply adjust based on the direction of the vehicle's front and body.
