Why Do We Keep Pressing the Clutch While Learning to Drive?

When learning to drive, we usually don't press the accelerator, drive slowly in first gear, and don't need to shift gears. Only the clutch provides power to the car—pressing it fully cuts off power, while releasing it gradually supplies power. That's why we keep pressing the clutch while learning to drive. Here's more about the clutch: 1. Clutch location: The clutch is housed in the flywheel casing between the engine and the transmission, secured to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the transmission. 2. Clutch function: While driving, the driver can press or release the clutch pedal as needed to temporarily disconnect or gradually engage the engine and transmission, cutting off or transferring engine power to the transmission. The clutch is a common component in mechanical transmission systems, allowing the drivetrain to be separated or engaged at any time.

Does a slightly deformed fender need repair?

No. The methods for repairing a dented fender are as follows: 1. Pulling: First, preheat the glue gun by plugging it in, then start pulling from the edge of the dent. Choose an appropriate pull tab, apply hot melt glue, and stick it to the corner of the dent. Wait for the glue to dry before starting to pull—it doesn’t need to be completely dry, as it won’t be sticky if it dries too thoroughly. Then, use a pull hammer to pull the tab. The advantage of using pull tabs is that they can quickly create a rough shape and are relatively uniform, but the downside is that they aren’t as precise. So, once the rough shape of the dent is formed, use the pushing method to handle the details. 2. Pushing: First, use a thick tool to work on the larger surface—the larger the contact area, the better. Then, use the same method with a fine hook to handle the details.

Will Points Be Deducted If the Rearview Mirror Crosses the Line During Reverse Parking?

Generally, points are not deducted if the rearview mirror crosses the line during reverse parking in the driving test, but this depends on the specific markings at each test site. According to the "Motor Vehicle Driving Training and Examination Syllabus," as long as the vehicle body does not exceed the ground markings, no points will be deducted. Since the rearview mirror protrudes, whether it is considered part of the vehicle body depends on how each test site recognizes it. Failing the test will result in disqualification. Other violations that result in a 100-point deduction include the vehicle body crossing the line, failing to enter the parking space, stopping midway, not following the designated route, incorrect sequence, or exceeding the allotted time. The full score for the second subject is 100 points, with evaluation criteria set for disqualification, 20-point deductions, 10-point deductions, and 5-point deductions. The rules for the second subject of the motor vehicle driver's license test state that any of the following will result in disqualification: stopping or rolling back midway during the test, not following voice prompts, or having the wheels or vehicle body cross the line. Many trainees encounter the issue of crossing the line during the second subject, and "crossing the line" is the most common reason for failing. The main cause of wheel crossing is not mastering the correct timing for steering. Apart from missing the right moment to steer, another reason could be the steering speed not matching the vehicle speed. Deduction standards for the second subject: Not wearing a seatbelt: 100-point deduction. Starting the engine without the gear in neutral: 100-point deduction. Not using turn signals (including when starting, changing lanes, overtaking, turning, or parking); turning on the signal for less than three seconds (note: this is easily overlooked!); forgetting to turn off the signal or using it incorrectly: 10-point deduction. Stalling once: 10-point deduction. Reverse parking: Not following the designated route sequence: 100-point deduction. Vehicle body crossing the line: 100-point deduction. Failing to enter the parking space: 100-point deduction. Before reversing, if both front wheels do not pass the control line: 100-point deduction. Exceeding the 210-second time limit: 100-point deduction. Stopping for more than 2 seconds midway: 5-point deduction per occurrence. Slope parking and starting: After stopping, if the front bumper is not aligned with the pole line and exceeds 50 cm forward or backward: 100-point deduction. After stopping, if the front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward: 10-point deduction. After stopping, if the starting time exceeds 30 seconds: 100-point deduction. Wheels crossing the road edge line while driving: 100-point deduction. Rolling back more than 30 cm when starting: 100-point deduction. After stopping, if the vehicle body is more than 50 cm from the road edge line: 100-point deduction. Not tightening the parking brake after stopping: 10-point deduction per occurrence. After stopping, if the vehicle body is between 30 cm and 50 cm from the road edge line: 10-point deduction per occurrence. Rolling back between 10 cm and 30 cm when starting: 5-point deduction per occurrence. Parallel parking: After parking, if the vehicle body crosses the line: 100-point deduction. Not using or incorrectly using turn signals when entering the parking space: 10-point deduction. Exceeding the 90-second time limit: 100-point deduction. Vehicle body touching the parking space boundary line while driving: 10-point deduction per occurrence. Wheels touching the lane boundary line while driving: 10-point deduction per occurrence. Stopping for more than 2 seconds midway: 5-point deduction per occurrence. 90-degree turn: Wheels crossing the road edge line: 100-point deduction. Not using or incorrectly using turn signals during the turn, or not turning them off afterward: 10-point deduction. Stopping for more than 2 seconds midway: 5-point deduction per occurrence. Curve driving: Wheels crossing the road edge line: 100-point deduction. Stopping for more than 2 seconds midway: 100-point deduction. Not driving in second gear or higher: 5-point deduction.

What is the appropriate tire pressure for Maxus V80?

Maxus V80 tire pressure standards are 2.4-2.5 bar for standard tires and 2.8-2.9 bar for reinforced tires. Due to seasonal factors, winter tire pressure can be appropriately increased by 0.2 bar, while summer pressure can be reduced by 0.1 bar. This data complies with the international GBT2978-2008 standard. To check the current tire pressure of Maxus V80 during daily driving, you can activate the tire pressure monitoring system, and the tire pressure values will be displayed on the central LCD screen of the instrument panel. The specific method is to press the LCD adjustment button on the combination instrument on the left side of the steering wheel to switch to the tire pressure monitoring system interface. Generally, tire pressure above 2.8 bar is considered too high, and below 2.0 bar is too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; weakens cord and rubber functions, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no seal on top, four small spikes below, and an exclamation mark inside), it is generally due to one of the following three reasons: Abnormal tire pressure: Usually triggers an alarm when below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the system will still record the previous data, causing the indicator light to come on. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving, the tire pressure fault light will illuminate. For sensor damage, only replacement with a new part is the solution.
