What to Pay Attention to in Subject 3?

Before getting into the car, walk around the bus counterclockwise to check the vehicle condition. The basic items of the Subject 3 test include preparation before starting, starting, driving straight, changing lanes, passing intersections, and other assessment items. During the Subject 3 test, pay attention to walking from the right rear of the car, around the front to the driver's seat. During the walk-around, observe the tire condition and check for any obstacles in front of or behind the car. When you reach the driver's door, report loudly and wait for permission to enter the driver's seat. Greet the examiner and present your ID: "Hello, examiner, I am XXX." At the same time, make eye contact with the invigilator at the upper right corner of the car for 2-3 seconds. While the examiner checks your ID, adjust your seat and fasten your seatbelt. Starting the car has fixed steps and sequences, which must be performed proficiently. Turn on the left turn signal, honk the horn twice, then press the clutch pedal, shift to first gear, gently lift the clutch pedal, slowly press the accelerator, turn the steering wheel to the left, and release the parking brake smoothly to start steadily. A smooth start is crucial. Many people press the accelerator suddenly, causing the car to jerk forward or stall. In Subject 3, this can affect the test results, which generally refer to the road driving skills test. Additionally, we usually refer to the safety and civilized driving knowledge test as "Subject 4." In fact, there is no such thing as Subject 4. Since the safety and civilized driving knowledge test is relatively simple, it will not be discussed in detail here. The road test consists of 16 procedures, each with standardized operations.

How to Turn on the Fog Lights of Toyota Vios?

Toyota Vios fog light activation steps are as follows: 1. Adjust the FAW Toyota Vios fog light knob to the middle position to turn on the front fog lights. 2. Adjust to the top position to turn on both front and rear fog lights. 3. Adjust to the "O" position to turn off the fog lights. Introduction to light usage is as follows: 1. In heavy rain with obstructed visibility, it is best to turn on the hazard warning lights, commonly known as "double flashing." The yellow light has better penetration in heavy rain, fog, and other weather conditions with obstructed visibility, making it easier for vehicles in front and behind to identify. Fog lights generally refer to automotive fog lights. Automotive fog lights are installed at the front and rear of the vehicle to illuminate the road and provide safety warnings during rainy and foggy weather, improving visibility for the driver and surrounding traffic participants. 2. The symbol for front fog lights is: three diagonal lines on the left, crossed by a curved line, and a semi-elliptical shape on the right. The symbol for rear fog lights is: a semi-elliptical shape on the left and three horizontal lines on the right, crossed by a curved line. 3. Fog lights can only be installed below the bumper, at the position closest to the ground, to ensure their effectiveness. If installed too high, the light cannot penetrate the rain and fog to illuminate the ground (fog is generally thinner below 1 meter), which can easily cause danger.

How Many Months Old is Considered a Stock Car?

Stock car is just a term used in the automotive sales industry, referring to new vehicles that remain unsold for an extended period after leaving the factory, thus becoming long-term inventory. There are no national regulations specifying how many months qualify a car as a stock car, but the industry generally considers vehicles unsold for over three months or half a year as stock cars. For imported vehicles, due to the lengthy time required for transportation, customs clearance, and entry procedures, the threshold is more lenient—typically, those unsold for over six months or a year are classified as stock cars. Vehicles unsold for over 12 months are considered stock cars, while those unsold for over two years are severely outdated inventory. The longer a car remains in stock, the greater the cost pressure on dealers, and the more outdated the model becomes, making stock cars often the first to undergo significant price reductions in the market. There is no specific time point or definition for stock cars. Normally, a vehicle requires a certain amount of time for production, assembly line completion, distribution by the general dealer, warehousing, and delivery. When inspecting stock cars unsold for over a year, check the exterior for paint discoloration, aging wiper blades, and tires to determine whether they were stored indoors or outdoors. Inspect the engine compartment pulleys and door/window seals for integrity. Turn off the engine, leave the headlights on for 10 minutes, and check if the battery can start the vehicle normally and whether the engine runs smoothly without abnormal vibrations to assess performance. "Cars parked for years are the worst." There is a consensus that if a car is left unused for a long time after purchase, its condition deteriorates far more than if driven daily. This principle also applies to unsold commercial vehicles. After months or even years in stock, the battery discharges, various oils degrade, and parts like tires deform from prolonged stationary contact with the ground.

What is the body length of the Hongqi H9?

The length, width, and height dimensions of the Hongqi H9 are 5137mm/1904mm/1493mm, which are official data. The length of the Hongqi H9 refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The turbocharged engine of the Hongqi H9 has a maximum power of 185kW and a maximum torque of 380 Nm. This engine delivers a maximum horsepower of 252 and a maximum torque speed range of 1800 to 4000 rpm. It features direct fuel injection technology and uses an aluminum alloy cylinder head and block. This engine is paired with a 7-speed wet dual-clutch transmission. There are national regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, under national standards, the significance of vehicle width data is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the requirements of public road usage.

What does the tire size 205/55R16 91H mean?

205 represents the tire's section width of 205 millimeters, 55 represents the tire's aspect ratio, R stands for radial tire, 16 indicates the rim diameter of 16 inches; 91 is the tire's load index; H represents the tire's speed rating. Tire size specification example (taking 195/55R15 as an example): 195 is the section width, which is the area of the tire that can contact the ground, measured in millimeters; 55 is the tire aspect ratio, which is the ratio of the tire's section height to section width. R is the construction mark, with R being the abbreviation for radial tire, while bias-ply tires are represented by the letter "B". Passenger car tires are generally radial tires. 15 is the tire's inner diameter, also known as the wheel diameter, usually measured in inches. Tires also have speed rating letter markings, indicating the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Common speed ratings include Q for 160 km/h, R for 170 km/h, S for 180 km/h, H for 210 km/h, V for 240 km/h, and W for 270 km/h. Precautions for replacing car tires: When selecting tires, the specifications should be the same as the previous tires and must match the other tire on the same axle, such as speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced because after changing tires, the aging cycles of the new tire and the valve stem differ. During the new tire's lifespan, the valve stem may develop issues, which are not easily noticeable. Therefore, it is best to replace the valve stem when changing tires. Installation direction and inflation: If using the original equipment tire, follow the manufacturer's installation requirements. For non-original tires, generally, the side with the production date should face outward. If it is a directional tire, align the arrow on the wheel with the car's forward direction during installation. During inflation, you can fill the tire to the maximum allowed pressure and then reduce it to the manufacturer's specified standard pressure.

What are the tips for Subject 2?

When you feel the front of the car tilting upward and the rear descending, the engine speed is generally around 1500 rpm, with the needle dropping two small squares, and the car slightly shaking. At this point, keep both feet still, quickly release the handbrake lever with your right hand all the way down, and the car will start moving slowly. If the car doesn't move, slightly lift the clutch pedal by two or three millimeters while gently pressing the accelerator, and the car will start. Note: Do not press the accelerator too hard; the engine speed should not exceed 2000 rpm. Sometimes the examiner may close the throttle, so pay attention to the clutch. Don't lift it too quickly; be more cautious. When you feel the car is about to move, quickly release the handbrake without hesitation. Single-sided bridge: First approach the left single-sided bridge. The left edge of the front hood is the guiding point for the left front wheel's path to the left bridge. After the front wheel leaves the left bridge, turn right. When you see the right bridge approaching the left edge again, turn back to the left. When the right bridge is near the middle of the front car, turn right a little more than one full circle to get onto the bridge. Then make minor adjustments to the direction. Remember the extension line of the right bridge; the path of the right front wheel should be within 20 cm of the middle of the front car. Continuous obstacles: Also known as riding obstacles. First, adjust the car to tilt left and align the first and second obstacles in a straight line with the car. When passing the second obstacle, look at the third obstacle in front of the left side of the car. When the left front wheel is in position, turn left. When you can't see the obstacle for one or two seconds, immediately turn right a little more. Look ahead at the fourth obstacle; when it's about to disappear from the right front of the car, turn left by about two positions, or a little more than one full circle. You can also see the fifth obstacle in the middle of the left side of the car. Move forward slightly, then turn right. Look at the fifth obstacle, turn left when the left front wheel is in position, and turn back when it's no longer visible. When aligned with the second and third obstacles, you can complete the task by riding over the sixth obstacle.
