How many test items are there in Subject 2?

For small vehicles C1 and C2, the test items include reverse parking, parallel parking, stopping and starting on a slope (canceled for C2), right-angle turns, and curve driving (commonly known as S-curve), totaling five mandatory items (some regions have a sixth item: highway card collection). For large vehicles A1, A2, A3, B1, and B2, the test items include pole test, stopping and starting on a slope, parallel parking, passing a single-plank bridge, curve driving, right-angle turns, passing a width-restricted gate, passing continuous obstacles, driving on bumpy roads, narrow road U-turns, as well as simulated 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 set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed if the following conditions are met: ① For applicants of 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. Subject 2 can be taken once, and if failed, a retake is allowed. If the retake is not attended or still results in failure, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of scheduled tests for Subject 2 and Subject 3 road driving skills cannot exceed five. If the fifth scheduled test still results in failure, the passing scores of other subjects will be invalidated.

How to Reset the Golf Tire Pressure Warning Light?

Golf Tire Pressure Light Reset: First, confirm whether the tire pressure is normal. If the tire pressure is normal, you can use the tire pressure reset button located next to the gear shift lever. Simply hold this button for 3 seconds while the vehicle's power is on to reset the tire pressure warning light. Here are the reasons why the Golf tire pressure warning light may illuminate: 1. Generally, there are several situations: rapid air loss, high pressure, low pressure, or high temperature. The warning light is a way to alert the driver based on tire pressure and other issues. It may also illuminate if the vehicle encounters uneven road surfaces during driving, causing uneven tire pressure. 2. If the tire pressure light does not illuminate, you should first check whether the tire pressure monitor is functioning properly before driving. If the tire pressure monitor fails to alert you in time when there is an issue, it indicates a problem with the monitor. 3. If the ignition switch is turned to ON/START and both the warning light and TPMS indicator light up for 2 seconds before turning off, it could mean that the vehicle's original receiver has not been properly learned and bound, or that the receiver controller was replaced without being learned and bound. In this case, you should visit a 4S shop and ask a professional to use a handheld learning tool to reacquire all tire sensor IDs and bind the receiver controller. 4. If the warning light does not illuminate when the ignition switch is turned from OFF to START or ON, it indicates a fault with the instrument panel warning light. You should visit a 4S shop and ask a professional to inspect the instrument panel. If the instrument panel is damaged, it will need to be replaced.

Can a C5 Driver's License Be Used on Highways?

Holders of a C5 driver's license, which corresponds to specially modified automatic transmission small passenger vehicles for disabled individuals, are permitted to drive on highways. The so-called C5 driver's license is essentially a license designed for disabled individuals who have not lost their driving abilities. Below are relevant details about the C5 driver's license: 1. According to the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses,' individuals with disabilities in the right lower limb or both lower limbs can apply for a C5 driver's license, which allows them to drive specially modified small and micro automatic transmission passenger vehicles for disabled individuals. The restriction to small passenger vehicles is primarily to address the travel needs of disabled individuals, with no current consideration for commercial freight vehicles. The restriction to automatic transmission vehicles is mainly due to their ease of operation, which is the internationally recognized standard for disabled drivers. 2. Individuals with disabilities in both lower limbs can apply for a C5 driver's license to operate specially modified small and micro automatic transmission passenger vehicles for disabled individuals.

What Causes Brake Shaking at High Speeds?

Brake shaking may be caused by the following reasons: 1. Brake system failure: If the car shakes whenever the brakes are applied while driving, the problem is likely with the brake discs. If the brake discs are not properly maintained during use, they may become deformed, causing rhythmic shaking during braking. If shaking only occurs during high-speed braking, brake disc deformation can be largely ruled out. 2. ABS anti-lock system failure: If the vehicle only shakes during high-speed braking, the issue may lie with the ABS anti-lock system. Some drivers may have experienced this: during emergency braking on icy or snowy roads, the brake pedal continuously rebounds, and the vehicle shakes along with it. This is caused by the ABS system's braking efficiency failing to meet braking demands. 3. Faulty components such as the ABS pump, sensor, or fixed shaft: High-speed driving requires greater braking force. If components like the ABS pump, sensor, or fixed shaft are aging or have poor contact, it can lead to brake shaking. Shaking during high-speed braking may also be related to aging or wear in the suspension system. For example, if the kingpin develops gaps due to wear, it can intermittently swing during intense braking, transmitting this movement to the vehicle body and causing high-speed brake shaking. 4. Incorrect wheel dynamic balance parameters: However, this type of shaking is related to the vehicle's speed, and the vehicle will shake regardless of whether the brakes are applied. If shaking only occurs during braking, dynamic balance issues can be ruled out.

What is the 0-100 km/h acceleration time of the Volkswagen Tiguan?

According to official data, the Volkswagen Tiguan comes in three engine displacements: the 1.4L model accelerates from 0-100 km/h in 10.3 seconds, the 1.8L in 9.2 seconds, and the 2.0L in 7.7 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque generally represents the strength of the force. The greater the torque, the stronger the force pushing the vehicle, resulting in faster acceleration. For example, the Nissan Patrol 4.0 has a maximum torque of 394 Nm and accelerates from 0-100 km/h in 9 seconds, while the Volkswagen Tiguan has a maximum torque of 350 Nm and accelerates in 7.7 seconds. Transmission efficiency: The transmission acts as a medium for power delivery, inevitably involving power loss. Higher transmission efficiency leads to better acceleration performance. Generally, the ranking of transmission efficiency is as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Volkswagen Tiguan is equipped with a 7-speed wet dual-clutch transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is called the power-to-weight ratio (unit: Hp/T). A higher power-to-weight ratio results in faster acceleration. For instance, the Nissan Patrol 4.0 has a power-to-weight ratio of 109 Hp/T and accelerates from 0-100 km/h in 9 seconds, whereas the Volkswagen Tiguan has a power-to-weight ratio of 1501.979 Hp/T and accelerates in 7.4 seconds.

What are the differences between domestically produced and imported Volvo XC40?

There is not much difference between the imported and domestically produced versions of the Volvo XC40. The only way to distinguish between the two is by the "Volvo" badge at the rear. The domestically produced version has the "Volvo Asia Pacific" label at the rear, while the imported version does not. Below are some details about the Volvo XC40: 1. The domestically produced XC40 remains consistent with the imported model, retaining its strong Nordic aesthetic and youthful, fashionable appeal. The front fascia features a vertical grille and the signature "Thor's Hammer" LED daytime running lights, ensuring high recognition. 2. The interior design of the domestically produced XC40 follows the same minimalist Nordic style as its exterior. It uses a large amount of eco-friendly materials, maintaining the high standard of being 100% odor-free. A 12.3-inch full LCD instrument panel and a 9-inch embedded central control screen come as standard across all models.
