How to Open the Fuel Tank Cap of a Toyota Corolla?

Toyota Corolla's fuel tank switch is located at the bottom left side of the driver's seat. Lift the fuel tank switch, and the fuel tank cap located at the rear left side of the vehicle will open. Then, slowly unscrew the fuel tank cap and hang it on the back of the fuel filler cap. When reinstalling the fuel tank cap, turn it until you hear a click, and the cap will slightly rotate back when released. Here is some related information: 1. The total volume of the Toyota Corolla's fuel tank is approximately 55 liters. It is recommended that owners stick to a fixed gas station for refueling. Frequently changing gas stations may result in the addition of low-quality fuel. 2. Frequently mixing gasoline from the two major brands, Sinopec and PetroChina, can lead to carbon buildup and affect engine performance due to differences in their refining processes, standards, and additives.

What to Do If Your Car Has a Flat Tire on the Road?

Here are the steps to handle the situation: 1. If your car has a flat tire, the first thing you should do is stay calm. When driving away from the main lane due to a flat or deflated tire, the driver must avoid emergency braking to prevent accidents. 2. When the driver realizes the tire has burst, they must firmly control the steering wheel and quickly shift to a lower gear. If the car starts to swerve, the driver should not overcorrect. Instead, they should gently press the brake pedal while maintaining control of the direction to slow the vehicle gradually—avoiding emergency braking. 3. Hold the steering wheel with both hands, try to keep the car moving straight, then release the accelerator and use gentle braking or no action at all, allowing the vehicle to slow down and stop. Throughout this process, avoid making any sudden or large movements to prevent the car from rolling over or fishtailing. 4. Pull over to the side of the road, take out the triangular warning sign, and place it behind the car. Generally, it should be placed 15-30 meters behind the vehicle, or farther at night. If you can change the tire yourself, do so; otherwise, call for roadside assistance or contact your dealership.

How long does it take to upgrade from an A3 driver's license to an A2?

More than three years. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses", the conditions for upgrading from A3 to A2 are: having held a medium-sized bus or large truck driver's license qualification for more than three years, or having held a large bus driver's license qualification for more than one year, and not having accumulated 12 penalty points in the most recent three scoring cycles before application. According to Article 15 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": For those who already hold a motor vehicle driver's license and apply to add a permitted driving category, there should be no record of accumulating 12 penalty points in the current scoring cycle and the most recent scoring cycle before application. For those applying to add medium-sized buses, tractors, or large buses to their permitted driving categories, the following provisions must also be met: Item 2: For those applying to add a tractor to their permitted driving categories, they must have held a medium-sized bus or large truck driver's license qualification for more than three years, or have held a large bus driver's license qualification for more than one year, and not have accumulated 12 penalty points in the most recent three scoring cycles before application. The permitted driving category for A3 is buses, while for A2 it is tractors, which are quite different fields. Additionally, the A3 driver's license is special; it is the only category A license that can be applied for directly when obtaining a driver's license for the first time. Conditions for upgrading to A2: No outstanding traffic violations, otherwise the upgrade cannot be applied for; must have held a B1 or B2 driver's license for more than two years; must be between 22 and 60 years old; and must not have accumulated 12 penalty points in the two most recent scoring cycles before application. An A3 driver's license can be upgraded to B2. The conditions are: must have held the A3 license for more than one year, and must not have accumulated 12 penalty points in the current scoring cycle and the most recent scoring cycle before application. The application must be processed at the vehicle management office where the A3 license was issued. According to the appendix of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses", the classification standards for driver's licenses are: A1, A2, A3, B1, B2, C1, C2, C3, C4, C5, D, E, F, M, N, P, totaling 16 categories. The Ministry of Public Security issued the "Regulations" to subdivide driver's licenses into 15 categories, with new licenses issued upon annual inspection or review. M-type driver's license permits driving wheeled self-propelled machinery; N-type driver's license permits driving trolleybuses; P-type driver's license permits driving trams. C1 driver's license: Many people think a C1 license only allows driving small vehicles with up to 7 seats. However, the C1 license permits driving small vehicles with up to 9 seats and a body length not exceeding 6 meters, such as Jinbei and Ruifeng models, as long as the seat count does not exceed 9 and the body length is under 6 meters. Other permitted driving categories for C1 are C2 (small automatic transmission vehicles), C3 (low-speed trucks), and C4 (three-wheeled vehicles). C2 driver's license: The C2 license is also one of the more common licenses. It only permits driving automatic transmission vehicles with up to 9 seats and a body length not exceeding 6 meters. Note that C2 license holders cannot drive manual transmission vehicles. B1 driver's license: The B1 license permits driving medium-sized buses, defined as medium-sized passenger vehicles not exceeding 6 meters in length, with a rated passenger capacity of 10 (inclusive) to 19 (inclusive). Other permitted driving categories are C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled vehicles), and M (wheeled self-propelled machinery). The B1 license does not include B2 among its permitted driving categories. B2 driver's license: The B2 license permits driving heavy or medium-sized trucks or large, heavy, or medium-sized specialized operation vehicles. Heavy or medium-sized trucks are mainly trucks, such as the large trucks commonly seen transporting construction debris. Other permitted driving categories for B2 are C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled vehicles), and M (wheeled self-propelled machinery), which is the same as the B1 license. A2 driver's license: The A2 license permits driving tractors. Only drivers with an A2 license can drive tractors; even those with an A1 license cannot. Other permitted driving categories for A2 are B1 (medium-sized buses), B2 (large trucks), C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled vehicles), and M (wheeled self-propelled machinery). A3 driver's license: The A3 license is somewhat special. Its permitted driving category is buses, which many people ride frequently. Other permitted driving categories are only C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), and C4 (three-wheeled vehicles). This license does not permit driving B1 or B2 category vehicles. Although buses and large passenger vehicles look similar, and some buses are even longer, an A3 license holder cannot drive large passenger vehicles.
