What does the snowflake symbol on the car dashboard mean?

Is the driving license valid for life or does it need to be renewed every few years?

The first renewal is after 6 years, and the second renewal is after 10 years. More extended information is as follows: 1. According to the "Road Traffic Safety Law": The initial validity period of a motor vehicle driving license is 6 years, with the first year being the probation period. After 6 years, the second renewal has a validity period of 10 years, and after 10 years, subsequent renewals are valid for life. The motor vehicle driver should apply for renewal at the vehicle management office where the driving license was issued within 90 days before the expiration of the current license. 2. There are two types of expiration for a driving license: First, annual inspection expiration. If the annual inspection is not conducted on time, the validity of the previous year's inspection expires. Failure to conduct the annual inspection means the vehicle has not undergone the required annual or biennial inspection. Vehicles without a valid inspection are not allowed to drive on public roads, and driving without it will result in penalties. Second, driving license validity expiration. This type of expiration is equivalent to not having a driving license. Vehicles without a valid driving license are also not allowed to drive on public roads and will face the same penalties.

What Causes the Car Belt to Squeak in Cold Weather?

The reasons for the car belt squeaking in cold weather are: 1. The belt tightens due to low temperature before the vehicle starts, causing noise; 2. The belt is severely aged and nearing the end of its service life; 3. The belt is too loose or too tight. The functions of the belt are: 1. Ensuring accurate intake and exhaust timing; 2. Synchronizing engine ignition and cylinder movement; 3. Ensuring smooth power output from the engine. The method for replacing the car belt is: 1. Lift the vehicle and remove the right front wheel fender liner; 2. Remove the alternator belt and the alternator belt tensioner; 3. Loosen the crankshaft pulley bolt; 4. Open the engine hood and remove the coolant reservoir; 5. Remove the engine mounting bracket and the protective cover on the belt; 6. Unscrew the alternator mounting bolt and remove the alternator; 7. Remove the cylinder block mounting bracket and take off the crankshaft pulley; 8. Rotate the crankshaft to the top dead center position of the cylinder and mark it; 9. Remove the belt and the tensioner.

What is the operation method for straight-line driving in Subject 2?

Hold the steering wheel straight and make slight adjustments left and right. The motor vehicle driver's license examination consists of the following four parts: 1. Subject 1: Road traffic rules, traffic signals, handling of traffic safety violations and accidents, regulations on the application and use of motor vehicle driver's licenses, motor vehicle registration, and other road traffic safety laws, regulations, and rules; 2. Subject 2: Testing the ability to reverse into a parking space, assessing the mastery of motor vehicle driving skills and the ability to judge the spatial position of the vehicle; 3. Subject 3: Evaluating the performance of driving a motor vehicle on the road to complete test items, compliance with traffic laws and regulations, and comprehensive control of the motor vehicle; proper use of lights, horns, seat belts, and other devices; ability to correctly observe and judge road traffic conditions; 4. Subject 4: Separating the knowledge related to safe and civilized driving from the original "Subject 1," as well as safe driving skills under complex conditions and emergency handling in critical situations, which are tested after the actual road driving test of "Subject 3" to further assess the candidate's traffic quality level.

Which is better, MT transmission or AT transmission?

MT transmission and AT transmission each have their own advantages, and there is no distinction of which is better. The relevant introductions are as follows: 1. MT transmission: MT, also known as manual transmission, requires manually shifting the gear lever to change the gear meshing device inside the transmission, which is more fuel-efficient. The pump wheel and turbine in an MT form a working pair, similar to two fans placed opposite each other. The wind from one fan drives the blades of the other fan to rotate, with the wind acting as the medium for kinetic energy transmission. If liquid is used instead of air as the medium for kinetic energy transmission, the pump wheel will drive the turbine to rotate through the liquid. By adding a guide wheel between the pump wheel and turbine, the speed difference between them can be achieved through reaction force, enabling variable speed and torque. 2. AT transmission: The AT automatic transmission consists of a hydraulic torque converter, planetary gear transmission, and control mechanism. AT does not require a clutch for shifting, has fewer gear changes with larger differences, and provides smooth connections, making it easier to operate. It not only offers convenience to the driver but also ensures comfort for passengers.

What Causes Abnormal Noise When Rolling Car Windows Up and Down?

There are several reasons that may cause abnormal noise when rolling car windows up and down: 1. Dirty or obstructed rubber window tracks: Door window rubber tracks tend to accumulate dust, which can create noise during window operation. In this case, first clean the dust from the rubber tracks with water, dry them thoroughly, and then spray some rubber protectant or lubricant on the tracks. This should eliminate the noise. 2. Aged rubber window tracks: Like windshield wipers, door window rubber tracks are constantly exposed to sun and rain, making them prone to aging and losing elasticity. Friction between the window glass and aged rubber tracks will produce noise, and the only solution is to replace the rubber tracks. 3. Dust or debris in the window regulator or a faulty regulator motor: The door window is operated by the window regulator at the bottom. Although the regulator is hidden inside the door, dust can still find its way in. Additionally, the regulator tracks and cables are coated with grease, making them more susceptible to dust accumulation. To resolve this, simply clean off the dust-contaminated grease from the regulator tracks and apply fresh grease to eliminate the noise.

What are the penalties for not wearing a seat belt in 2021?

In 2021, not wearing a seat belt will result in a fine of 50 yuan and a deduction of 2 points. Here are the relevant details: 1. Legal aspects: Article 51 of the Road Traffic Safety Law of the People's Republic of China stipulates that when a motor vehicle is in motion, the driver and passengers should use seat belts as required. If the driver of a motor vehicle does not wear a seat belt as required while driving on a highway or urban expressway, 2 points will be deducted. A driver who fails to use a seat belt as required will be fined 50 yuan. 2. Safety aspects: As is well known, when a car collides or encounters an emergency braking situation, it will generate a huge inertial force, causing secondary collisions between the driver, passengers, and objects inside the car such as the steering wheel, windshield, and seat backrest. This can easily cause severe injuries to the occupants, or even eject them from their seats or out of the vehicle. Seat belts can restrain the driver and passengers in their seats, preventing secondary collisions. Moreover, their cushioning effect can absorb a large amount of kinetic energy, reducing the severity of injuries to the occupants.
