What reference points should be observed for parallel parking in Subject 2?

Subject 2 driving test consists of five items: reverse parking, parallel parking, hill start, right-angle turn, and curve driving. For parallel parking, there are three key reference points that require special attention. First reference point: Steer fully right: It's relatively easier to locate the parking spot through the rearview mirror. When the front horizontal yellow line of the right parking space disappears from the right rearview mirror, gradually turn the steering wheel fully to the right. Second reference point: Straighten the wheels: When observing from the driver's seat, straighten the steering wheel immediately upon seeing the rear right corner of the parking space appear in the left rearview mirror. Third reference point: Steer fully left: While turning left, observe the left rearview mirror. When the left rear wheel just touches the white dashed line, quickly turn the steering wheel fully to the left. Parallel parking test criteria: 100 points deduction if the vehicle body crosses the line after parking. 10 points deduction if wheels touch the lane boundary during movement. 100 points deduction for failing to park completely within the space. 10 points deduction for not activating the left turn signal before starting. 100 points deduction for stopping during the maneuver.

Is the BM3 Tuning Stable?

BM3 tuning is not stable and may lead to engine damage. Below are specific instructions regarding BM3 tuning: 1. TU Engines: If the engine is a B48TU, it is not recommended to install BM3 tuning, as the air-cooling system of the B48TU is inferior in performance compared to later water-cooled versions. 2. Water-Cooled Engines: BM3 tuning can increase power by 46%, which means the engine generates more heat. Without modifications to the cooling system, engine damage may occur. For water-cooled B48 engines, installing a Stage 1 BM3 tuning is relatively safer.

What is the reason for the absence of urea reflux sound after engine shutdown?

After engine shutdown, the absence of urea reflux sound may be caused by a malfunction in the urea recovery device, and it should be inspected and repaired at a 4S shop as soon as possible. Below is relevant information about automotive urea: 1. The role of automotive urea: Generally, adding urea to vehicles is primarily to reduce exhaust emissions, as diesel engine exhaust mainly consists of nitrogen oxides and carbon particles. 2. National regulations: Because vehicle exhaust emissions pose significant harm to both people and the environment. Therefore, the National IV standard implemented in 2008 in China stipulates that diesel vehicles must use automotive urea in their emission reduction systems.

What does CJ-4 diesel engine oil represent?

CJ-4 diesel engine oil represents the highest quality grade, where -4 indicates that the oil is suitable for 4-stroke diesel engines. Below are specific details about engine oil: 1. Oil Types: Engine oil grades are categorized into gasoline, diesel, and gasoline-diesel universal types. Oils starting with the letter "S" are for gasoline engines, with specifications including API SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN. Oils starting with the letter "C" are for diesel engines, with specifications including API CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. If both letters are present, such as SM/CF, it indicates the oil is a gasoline-diesel universal type. 2. Letter Meanings: The further the letter after S or C is in the alphabet, the higher the oil's quality grade, indicating more stable performance and a higher oil grade. Currently, the market also classifies engine oils into three categories: mineral oil, semi-synthetic oil, and synthetic oil. Correspondingly, oil grades from SA to SJ are mineral oils, SJ and SL are semi-synthetic oils, and SM and SN are full synthetic oils. In addition to oil grade identifiers, some oil packaging may feature the SAE label. SAE stands for the Society of Automotive Engineers, which sets standard viscosity values for engine oils, such as 5W-30.

What Does Car Insurance Cover?

Car insurance includes compulsory traffic insurance, vehicle damage insurance, third-party liability insurance, passenger liability insurance, total loss theft insurance, glass breakage insurance and other basic insurances, as well as additional insurances such as body scratch insurance, spontaneous combustion insurance, water driving insurance, cargo falling liability insurance, and no-deductible special liability insurance. Below is an introduction to some of the car insurances: 1. Vehicle damage insurance: Used to compensate for losses caused by natural disasters and accidents to the vehicle itself. It is recommended for beginners to purchase. 2. Third-party liability insurance: Used to compensate for losses caused by the car owner to third-party personal injuries or deaths. This must be purchased as it provides protection for both yourself and others. 3. No-deductible insurance: An additional insurance that transfers the responsibility the car owner needs to bear to the insurance company, reducing the owner's losses. If both vehicle damage insurance and third-party liability insurance are purchased, it is best to also purchase no-deductible insurance. 4. Theft insurance: Used to compensate for damages caused by vehicle theft, robbery, or seizure. It is recommended for new car owners without garages to purchase. 5. Passenger liability insurance: Used to compensate for losses suffered by the driver and passengers in the car due to traffic accidents. Premiums are generally paid per seat. It is recommended for beginners or family car owners to purchase.
