Tire production dates are indicated by a four-digit number, which is printed on the sidewall of the tire. The first two digits represent the week of production, while the last two digits indicate the year. The international standard tire code consists of six parts: 1. Tire width. 2. The percentage of tire section height to aspect ratio. 3. Tire type code. 4. Rim diameter (in inches). 5. Load index (permissible load mass code). 6. Permissible speed code. There are two methods for identifying car tire specifications: 1. A tire marked as "5.60-13" indicates a tire width of 5.60 inches and a rim diameter of 13 inches. 2. A tire marked as "195/60R14" indicates a tire width of 195mm, an aspect ratio of 60, and a rim diameter of 14 inches.

Does the BMW 530 come with a built-in dash cam?

BMW 530 comes with a built-in dash cam. The dash cam should be able to record normally while the car is in motion. After parking, it should also be able to record for the first few hours (for anti-theft monitoring). When the battery power drops, the dash cam will stop recording to protect the battery and ensure the car has enough power to start the next time. Below are the functions of a dash cam: 1. A dash cam is a device that records images, sounds, and related information during vehicle travel. In simple terms, it is equivalent to the black box installed on an airplane, meaning it serves as a black box for cars. Essentially, it is a car camera that can record high-definition footage, capturing images, sounds, and vehicle data during travel. 2. In the event of an unexpected traffic accident, it provides strong evidence for the driver. Drivers can immediately present the recorded data as evidence to protect their rights and interests. 3. It allows for quick, truthful, and accurate use of video footage to assist traffic police in handling accidents fairly, justly, and reasonably, avoiding unfair treatment.

Should You Engage First Gear or Release the Handbrake First in Subject Two?

First, engage the first gear, and then release the handbrake. When engaging the first gear, you need to press the clutch pedal and the brake pedal to effectively prevent the vehicle from rolling backward. In the Subject Two driving test, rolling backward during the third item—fixed-point stopping and starting on a slope—will result in point deductions. Below is additional information: 1. Subject Two Test Items: There are five test items in Subject Two. The first test item is parallel parking, the second is reversing into a parking space. The third test item is fixed-point stopping and starting on a slope, the fourth is making a right-angle turn, and the fifth is driving through curves. Passing all these items completes the Subject Two test. 2. Precautions for the Subject Two Test: Before the test, it is necessary to conduct a mock test once to familiarize yourself with the vehicle and the test site. After entering the vehicle, the first thing to do is fasten the seatbelt and adjust the seat and rearview mirror angles. If you fail the first attempt, you must immediately exit the vehicle and wait for the staff to move the vehicle back to the starting position for another attempt.

What are the advantages of inline engines?

The advantages of inline engines are that the cylinders are arranged in a straight line, with a simple structure for the cylinder block, cylinder head, and crankshaft, low manufacturing costs, good low-speed torque characteristics, low fuel consumption, and compact size, making them widely used. Most engines with fewer than 5 cylinders are arranged in an inline configuration, and now a few 6-cylinder engines also use this arrangement. In the past, there were even inline 8-cylinder engines. Gasoline engines below 1 liter often use an inline 3-cylinder configuration, those between 1 and 2.5 liters typically use an inline 4-cylinder, and a few use an inline 5-cylinder, though achieving dynamic balance is more challenging. Some four-wheel-drive vehicles use an inline 6-cylinder engine because of its narrow width, allowing space for turbochargers and other equipment. The inline 6-cylinder configuration offers better dynamic balance and relatively lower vibration, making it popular in many mid-range and luxury cars.

What does the zigzag line on the highway represent?

The zigzag line on the highway represents longitudinal deceleration markings. Here are some precautions for driving on the highway: 1. Both the driver and front-seat passenger should fasten their seat belts, and the driver should not answer phone calls; 2. Avoid making sharp turns with the steering wheel while driving at high speeds; 3. Do not change lanes arbitrarily while driving. When changing lanes or overtaking the vehicle ahead, the turn signal must be activated in advance; 4. Only adjacent lanes are allowed for overtaking, and the vehicle should return to the driving lane immediately after overtaking. Vehicles must not ride or press on the lane dividing line; 5. Do not reverse, drive in the opposite direction, cross the central divider to make a U-turn or turn, do not test drive or operate a training vehicle, and do not overtake or park on the ramp; 6. Maintain a following distance of more than 100 meters. When the speed is below 100 kilometers per hour, the distance from the vehicle ahead in the same lane can be appropriately shortened, but the minimum distance should not be less than 50 meters.

How Long is Considered as Inventory Car?

Inventory car refers to vehicles that have been in stock for over a year without being sold. There is no clear legal definition for inventory cars, but the term is commonly used in the automotive sales industry. Here are some extended details: 1. Inspection of inventory cars: Inventory cars are often dirty, so extra caution is required when selecting one. After a thorough cleaning, carefully inspect the paint for scratches and dents. If components like wiper blades, engine belts, and tires show no significant signs of aging, the storage conditions are likely acceptable. Checking the battery status can indicate how well the dealer maintains inventory cars. If the battery is periodically charged, the status window should display a green light, indicating normal condition. Also, verify that the VIN code on the certificate matches the engine number and that the stamped numbers are neat and unaltered. 2. Considerations when purchasing a one-year-old inventory car: New cars stored for less than a year can be purchased, often with substantial discounts. However, it's advisable to request the 4S store to replace the original engine oil and check the tire manufacturing date. New tires over two years old may face rubber aging risks, so replacement should also be requested from the 4S store.
