Is 4L High-Speed Four-Wheel Drive or Low-Speed Four-Wheel Drive?

4L stands for low-speed four-wheel drive. The transfer case has larger gears, which can amplify torque, reduce speed, and increase power. It is suitable for extremely harsh road conditions. High-speed four-wheel drive mode is referred to as 4H, while 4L is the low-speed four-wheel drive mode. There are three common four-wheel drive systems in vehicles: full-time four-wheel drive, part-time four-wheel drive, and on-demand four-wheel drive. These three systems have different structures and functions. Full-time four-wheel drive means the vehicle maintains four-wheel drive throughout the entire driving process, with the engine's torque distributed to the front and rear wheels at a fixed ratio. This mode provides excellent off-road and handling performance at all times but cannot adjust torque distribution based on road conditions and has higher fuel consumption. On-demand four-wheel drive is controlled by a computer chip that switches between two-wheel drive and four-wheel drive. On normal roads, the vehicle operates in two-wheel drive mode. When encountering off-road conditions or wheel slippage, the computer detects and automatically distributes power to the other wheels. The quality of the control program affects the intelligence of the drive mode switching. Additionally, there is a part-time four-wheel drive (Part-Time 4WD) system, which is manually controlled by the driver to switch drive modes. Many SUVs and off-road vehicles now combine one or more of these four-wheel drive modes to complement each other's strengths and weaknesses.

What brand is Comfortmax tire?

Comfortmax is the comfort series tire of Giti. Comprehensive optimization: Giti tires adopt soft sound noise reduction technology, comprehensively optimizing tire noise by considering factors such as loudness, sharpness, roughness, and fluctuation. Optimization effect: Reduces air noise caused by tire rolling during vehicle movement, as well as vehicle noise caused by tire vibration, further enhancing driving quietness and comfort, providing a sense of harmonious driving pleasure. Noise reduction: Comfort tires reduce pattern noise by optimizing the length and arrangement sequence of tread blocks, using multiple sets of tread blocks in staggered arrangement. Additionally, multi-angle tread grooves can reduce air noise caused by the pumping effect, combined with an optimized tire contour, which reduces noise from vehicle and tire structural vibrations during driving.

Can You Skip Gears When Downshifting in Subject Three?

Subject Three examination allows skipping gears when downshifting, but not when upshifting. During the Subject Three test, before shifting gears, it is essential to adjust the speed to match the intended gear, then proceed with the gear shift. Many intersection stops require skipping gears when downshifting. After the gear shifting operation begins, follow the voice prompts: shift to second gear (at this point, depress the clutch, engage third gear, and immediately accelerate to around 35km/h, ensuring not to exceed 40km/h), voice prompt to shift to third gear (depress the clutch, release the throttle, and engage fourth gear), voice prompt to shift to fourth gear (release the throttle, depress the clutch, and downshift to third gear), voice prompt to shift to third gear (depress the clutch, release the throttle, engage second gear, lightly press the brake pedal, and reduce speed to 25km/h). Deduction points for gear shifting operations: failing to smoothly shift gears as instructed results in a 100-point deduction; mismatch between running speed and gear results in a 10-point deduction. According to the Ministry of Public Security's regulations on driver examinations, each candidate has two attempts per appointment. If the first attempt is unsuccessful, an immediate retake is allowed. During the first attempt, candidates must complete a vehicle inspection walk-around and nighttime light simulation. If the first attempt fails, the second retake does not require the walk-around or light simulation; preparation can be completed directly before starting the second test. Candidates taking the daytime test must complete the nighttime light simulation, while those taking the nighttime test will not be evaluated on this item.

Can Subject 3 and Subject 4 be Scheduled Together?

C1 driver's license Subject 3 and Subject 4 can be scheduled simultaneously. If the test venues for Subject 3 and Subject 4 are in the same location, you can directly take the Subject 4 test without an additional appointment. If you fail the Subject 4 test on the first attempt, you will need to schedule the next test online. In some regions, after completing Subject 3, you can immediately schedule Subject 4 online, and the test can be arranged on the same day. The vehicle management office must arrange the test according to the scheduled venue and time. After passing Subject 1, the applicant can schedule Subject 2 or Subject 3 road driving skills test. In some areas, applicants can simultaneously schedule Subject 2 and Subject 3 road driving skills tests. If the scheduling is successful, the tests can be taken consecutively. After passing both Subject 2 and Subject 3 road driving skills tests, the applicant can take the Subject 3 safety and civilized driving knowledge test on the same day. If the vehicle management office cannot arrange the Subject 2 or Subject 3 road driving skills test within 60 days, the applicant can choose to schedule the test at another venue within the same province (autonomous region, or municipality directly under the central government).

Do I need to keep my foot on the accelerator when driving an automatic car?

When driving an automatic car, you don't need to keep your foot on the accelerator all the time. You can use cruise control to maintain a constant speed. When overtaking, press the accelerator, and after completing the overtaking, release the accelerator to return to the original speed. Lightly pressing the brake can turn off the cruise control. Precautions for driving an automatic car: Be careful not to coast in neutral. Many drivers believe that coasting in neutral saves fuel, but for automatic cars, coasting in neutral does not achieve fuel savings. Prolonged coasting in neutral can lead to insufficient oil pressure in the hydraulic lines of the automatic transmission, which not only increases friction and reduces lubrication but also damages the friction plates inside the automatic transmission. Precautions for parking an automatic car: When parking, the method for automatic cars is completely different from manual cars. When parking an automatic car or idling for a long time, you should first press the brake, shift into N (Neutral), then engage the handbrake and release the brake pedal. Once the car is completely stopped, shift into P (Park).
