The reason for the noise when braking in reverse is due to the moving caliper hitting the caliper bracket during the process of reversing. Below are the relevant explanations: 1. Radar System: When the car moves from the warning zone into the danger zone, the radar system automatically activates the braking device to control the car's reverse movement. The principle is based on an ordinary reverse radar, with the addition of a servo device that has a braking function. When the car enters the danger zone from the warning zone, the controller sends a control signal to the braking servo, which immediately activates to automatically stop the car from reversing further, ensuring safe reversing. 2. Braking: When driving forward and braking, there is no 'play gap' at the lower connection part of the brake bracket, so no noise occurs. However, when braking in reverse, the brake caliper lifts up and hits the upper bracket, causing the noise.

What license plate is required for sedans exceeding 5 meters?

Sedans exceeding 5 meters require a blue license plate. Below is a detailed explanation of vehicle license plate colors: 1. Blue background with white characters: Typically exclusive to small vehicles, but not limited to sedans. Passenger vehicles with fewer than 9 seats and commercial trucks with a load capacity below 1.5 tons can also use blue plates. 2. Yellow background with black characters: Vehicles with yellow plates mainly include large trucks, ordinary M2-class light buses, medium and large buses, agricultural vehicles, trailers, minivans with 10 or more seats, and trucks with a load capacity exceeding 1.0 tons. 3. White background with black characters: White plates are commonly seen on vehicles belonging to public security departments, judicial authorities, procuratorates, armed police forces, and the People's Liberation Army, representing national authority institutions. 4. Black background with white characters: The first type of black plate is the Yue Z plate issued by the Guangdong Provincial Public Security Department, primarily facilitating travel between Guangdong, Hong Kong, and Macau. The other type is for foreign institutions in China, such as consulates, which can have black plates indicating embassy-exclusive vehicles, often displaying the country's flag. 5. Green background with black characters: This is the plate for new energy vehicles promoted in recent years, but not all new energy vehicles qualify. Pure electric vehicles (PEV), plug-in hybrid electric vehicles (PHEV), and fuel cell electric vehicles (FCEV) can use green plates, while hybrid electric vehicles (HEV) cannot.

Is the Audi Q2L equipped with a dry or wet dual-clutch transmission?

Audi Q2L uses a dry dual-clutch transmission. In a dry transmission, the medium between the components is air, whereas in a wet transmission, it is oil. Here is some relevant information about dual-clutch transmissions: 1. A dual-clutch transmission is a product developed based on manual transmissions, and its structure is quite similar to that of a manual transmission. 2. A dual-clutch transmission simply has one additional clutch and a set of gear-shifting control mechanisms compared to a manual transmission. One clutch controls the odd-numbered gears, while the other controls the even-numbered gears. Dual-clutch transmissions are known for their fast gear-shifting speed and high transmission efficiency.

What to use to clean the many spots left under a tree where the car was parked?

Spots left under a tree where the car was parked are tree sap, which contains a certain level of acidity. If not cleaned in time, prolonged attachment to the car can damage the paint. The cleaning methods for tree sap are as follows: 1. Hot water and a towel: Tree sap is usually difficult to remove with cold water, but hot water can soften the sap, making it easier to clean than with cold water. 2. Car wash clay: Car wash clay not only has strong cleaning power but also a certain polishing effect. However, this method is generally suitable for small-scale cleaning, as large-scale cleaning can be more labor-intensive. 3. Tree sap cleaner: Tree sap cleaner has stronger cleaning power but can cause slight damage to the car paint. After use, it's best to wax and polish the paint surface to better protect it.

What are the items in Subject 2?

The C1 and C2 driving tests include five mandatory items: reversing into a garage, parallel parking, stopping and starting on a slope (canceled for C2), turning at a right angle, and driving on an S-curve (commonly known as the S-bend). Some regions also include a sixth item: collecting a card on a highway. The A1, A2, A3, B1, and B2 driving tests include the following items: pole test, stopping and starting on a slope, parallel parking, crossing a single-plank bridge, driving on an S-curve, turning at a right angle, passing through a width-restricted gate, navigating continuous obstacles, driving on bumpy roads, making a U-turn on a narrow road, and simulations of highway driving, continuous sharp turns on mountain roads, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling. The full score for Subject 2 is 100 points, with evaluation criteria for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed under the following conditions: ① For large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. If a candidate fails the Subject 2 test, they can retake it once. If they do not take the retest or fail the retest, the test is terminated, and the applicant must reschedule the test after ten days. During the validity period of the driving skill test permit, the number of rescheduled tests for Subject 2 and Subject 3 road driving skills must not exceed five. If the fifth rescheduled test is still failed, the results of other passed subjects will be invalidated.

Got a driver's license years ago but forgot where to start practicing driving?

Here are specific instructions for practicing driving skills after not driving for several years with a license: 1. Practice gear shifting: Gear shifting follows the principle of matching gear with speed. Generally, shift to the corresponding gear based on the speed (e.g., 1st gear at around 10km/h, 5th gear at 50km/h or above). For manual transmission, first press the clutch, then shift gears, and slowly release the clutch. For automatic transmission, press the brake before shifting gears, and release the brake after shifting. 2. Drive straight: To practice driving straight, find a reference point on the front of the car and maintain the distance between the reference point and the reference object while driving. 3. Practice reversing: When reversing, judge the vehicle's position through the rearview mirrors, keeping a certain distance or positional relationship (such as parallel) between the car body and the sideline in the left and right rearview mirrors. If necessary, get out of the car to observe the actual distance and make adjustments. 4. Learn parking: Before parking, learn to follow the line, aligning the door handle in the rearview mirror just with the roadside line. At this point, the distance between the right side of the car body and the roadside line is about 30 centimeters, and you can press the brake and clutch to stop.
