What Should You Pay Attention to During the Probationary Period of a Driver's License?

Here are the precautions during the probationary period of a driver's license: 1. You cannot drive on highways alone during the probationary period. If a driver operates a motor vehicle on a highway during the probationary period, they must be accompanied by a driver who has held a driver's license for the corresponding or higher vehicle class for more than three years. The accompanying driver should sit in the front passenger seat to guide the probationary driver. If there is no accompanying driver or the accompanying driver does not meet the requirements, a fine of 200 yuan will be imposed. 2. A probationary sign must be displayed when driving during the probationary period. If you borrow or rent a car during the probationary period, you must also display the probationary sign as required. Without it, you cannot drive. 3. Accumulating 12 penalty points will require retaking the exams. During the probationary period, the driver's license can still incur penalty points, but you should be more cautious and avoid accumulating 12 points. If you accumulate 12 points during the probationary period, your driver's license will be revoked, meaning you will need to re-register and retake the exams for Subject 1, Subject 2, and Subject 3 from the beginning.

Is Wheel Alignment Necessary After Changing Tires?

After replacing or repairing tires, it is necessary to perform a wheel alignment on the vehicle. Below are the specific details about wheel alignment: 1. Because there are certain angles and relative positions between the car tires, steering mechanism, and front/rear axles, these angles and positions may shift after changing tires. This can lead to issues such as the vehicle pulling to one side, reduced steering precision, misaligned steering wheel, or uneven tire wear, making timely wheel alignment essential. 2. Wheel alignment ensures the tires maintain the optimal angle relative to the vehicle body, reducing wear between the tires and steering components during driving. It also ensures tight contact between the tires and the road, allowing the car to maintain stable straight-line driving. 3. Patching a tire does not require wheel alignment; only dynamic balancing is needed. Performing wheel alignment after patching a tire can easily disrupt the balance of the vehicle's suspension.

Should the Audi Gliding Function Be Turned Off?

Audi's intelligent gliding function should not be turned off, as it automatically adjusts based on conditions such as vehicle speed and engine RPM. Relevant details are as follows: 1. The 2021 Audi A3 Sportback 35TFSI Progressive Sport is a compact 5-door, 5-seat hatchback equipped with a 7-speed dual-clutch transmission, capable of reaching a top speed of 210 km/h. 2. The 2021 Audi A3 Sportback 35TFSI Progressive Sport measures 4351mm in length, 1815mm in width, and 1458mm in height, with a wheelbase of 2630mm. It features a MacPherson strut front suspension and a multi-link rear suspension, with tire specifications of 225/45R17.

Should the Clutch Be Depressed When Turning in Subject Three?

When turning in Subject Three, do not depress the clutch. The precautions for the Subject Three test are as follows: 1. The clutch should only be used during starting, shifting up, shifting down, and stopping. Do not depress the clutch during normal driving. When encountering a situation requiring slight deceleration, only apply the brake to avoid coasting. 2. The traffic light will flash several times before changing from green to red. At this point, based on the distance to the intersection and the vehicle speed, if the distance is short and the speed has not decreased, depress the accelerator. 3. After completing the Subject Three road test, when the examiner gives the command to "pull over and stop," as long as it is not at an intersection or on a solid line, stop decisively. 4. Upon hearing the command, assess the road conditions. If there are no solid lines or you are not too close to the intersection, quickly turn on the right signal, check the rearview mirror, brake to decelerate, and merge. Position the vehicle slightly to the right of the center of the road, turn the steering wheel back to the left, and depress the clutch when the vehicle can coast to straighten out. Once the vehicle is straight, turn the wheel to the right to align and stop.

Where is the Air Filter in a Sedan?

The location of the air filter element in a car depends on the intake form and the structure of the engine. Generally, it is located in the air cleaner on the engine intake pipe. There are two types of air filters in cars: dry and wet. The dry type is made of paper or organic materials, while the wet type is made of metal mesh. The air filter should be replaced every 10,000 to 20,000 kilometers or during each maintenance interval. However, it is recommended to clean the air filter every 5,000 kilometers to reduce the formation of throttle sludge. The function of the air filter: to filter out particulate impurities in the air, ensuring that sufficient clean air enters the cylinder and preventing airborne dust from being sucked into the engine, which accelerates the wear of the piston group and cylinder. Air filter: It is a type of filter, also known as an air filter cartridge, air cleaner, or style. It is mainly used in engineering vehicles, cars, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms as an air filter. During operation, the engine sucks in a large amount of air. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe cylinder scoring, especially in dry and sandy working environments. The air cleaner is installed in front of the carburetor or intake pipe to filter out dust and sand particles from the air, ensuring that sufficient and clean air enters the cylinder. Using a dirty air filter while driving can cause insufficient engine intake, incomplete fuel combustion, leading to unstable engine operation, reduced power, and increased fuel consumption. Therefore, the air filter must be kept clean. The car air cleaner is a device that removes particulate impurities from the air, consisting of one or several components that clean the air. Its main function is to filter out harmful impurities from the air before it enters the cylinder, reducing early wear of the cylinder, piston, piston rings, valves, and valve seats. Therefore, before air enters the cylinder, it must first pass through the fine filtration of the air cleaner. A dirty air cleaner can cause poor engine performance, excessive fuel consumption, and engine damage. When inspecting the air cleaner, if it is found to have little dust and minor blockage, it can be cleaned by blowing compressed air from the inside out and reused. A severely dirty air filter should be replaced promptly.

What are the common faults of turbochargers?

The following are specific introductions to common faults of automotive turbochargers: 1. Oil leakage fault of turbocharger. The oil consumption is large, but the exhaust smoke color is normal and the power does not decrease. It is generally caused by oil leakage. 2. The oil consumption is large, the exhaust emits blue smoke, but the power does not decrease. It is caused by oil leakage at the compressor end of the turbocharger, and the oil enters the combustion chamber through the engine intake pipe and is burned. 3. The oil consumption is large, the exhaust emits blue or black smoke, and the power decreases. The gap between the piston and the cylinder is excessively worn, and the oil enters the combustion chamber and is burned. 4. There is metal friction sound in the turbocharger. The exhaust emits black smoke, the power decreases, and there is abnormal noise in the turbocharger. It may be caused by excessive wear of the turbocharger rotor bearing or thrust bearing, and the impeller rubs against the turbocharger housing.
