How to Ensure Not Crossing the Line in the S-Curve During Subject Two?

Here are the methods to ensure not crossing the line in the S-curve during Subject Two: 1. When entering the curve, position the front of the car in the middle; when the left corner of the car touches the right line, turn the steering wheel left by one full turn plus 45 degrees and maintain the course; when the left corner touches the left line of the second curve, straighten the steering wheel; when the right corner of the car touches the left line of the second curve, turn the steering wheel right by one full turn plus 45 degrees; when the car is straight again, straighten the steering wheel and slowly exit the S-curve. 2. While navigating the S-curve, it's crucial to control the speed properly. Press the clutch gently to slow down, increasing reaction time. Even if there's a slight deviation in direction, it can be adjusted in time to avoid crossing the line. 3. There are two types of entrances, left and right. For a left entrance, keep the car as close to the right line as possible before turning the steering wheel left; for a right entrance, do the opposite—keep the car close to the left line before turning the steering wheel right. This accounts for the inner wheel difference, preventing the rear wheels from crossing the line during the turn.

How to Use Engine Internal Cleaner?

Engine internal cleaner is used by following these steps: 1. Add the cleaner to the engine oil before an oil change to flush out harmful sludge along with the old oil; 2. Add new engine oil; 3. Add an engine super additive protector product, then start the engine and let it idle for a period of time; 4. Turn off the engine, drain the old oil, replace the oil filter, and add new oil. Engine internal cleaner can remove residual dirty sludge from the engine oil passages and, to some extent, clean carbon deposits from the piston rings and ring grooves, providing practical maintenance benefits for the engine.

What are the reasons for the Volkswagen car air conditioner not cooling?

Reasons for Volkswagen car air conditioner not cooling: 1. Insufficient or too little refrigerant: A common reason for the car air conditioner not cooling is insufficient or too little refrigerant, which is likely caused by minor leaks. 2. Too much refrigerant: Excessive refrigerant can also cause the air conditioner not to cool, as there is a required proportion of refrigerant volume in the air conditioning system. If the proportion is too high, it can affect heat dissipation. Similarly, adding too much cooling oil during maintenance can also reduce the heat dissipation of the refrigeration system. 3. Loose drive belt of the car air conditioner compressor: Car refrigeration relies on refrigerant, and refrigerant transmission depends on the air conditioner compressor, with the drive belt being a crucial moving part that drives the compressor. If the drive belt is loose, the compressor may slip during operation, leading to reduced transmission efficiency, lower compressor speed, decreased refrigerant delivery, and ultimately causing the car air conditioner not to cool. 4. Substandard refrigerant and freezing oil: Excessive impurities in the refrigerant and freezing oil can clog the car air conditioner's filter, increasing resistance and reducing the flow of refrigerant to the expansion valve, resulting in insufficient cooling capacity. 5. Moisture infiltration in the refrigeration system: If moisture enters the car air conditioner refrigeration system, it can cause insufficient cooling or no cooling at all.

How to Press the Clutch When Shifting Gears?

Here are the methods for pressing the clutch when shifting gears: 1. The correct way to press the clutch when shifting is to use the ball of your left foot while keeping your left heel as the pivot point. 2. When starting the vehicle, quickly press the clutch pedal all the way down, shift into first gear, and slowly release the clutch to the semi-engaged position. Simultaneously, press the accelerator with your right foot—not too deeply—just enough to slightly increase the engine speed. Then release the handbrake. Once the vehicle starts smoothly, you can fully release the clutch. 3. Starting on flat ground. After pressing the clutch and shifting into gear, release the clutch slowly since the vehicle hasn't gained speed yet. Releasing the clutch too quickly may cause the engine to stall. 4. Starting on a slope. Slowly release the clutch until the engine idles roughly, then release the brake pedal and immediately press the accelerator to match. 5. Beginners can also rely on the handbrake for safer driving. When shifting from first to second gear or second to third, release the clutch slowly. For shifts from third to fourth or fourth to fifth, release the clutch quickly. At lower speeds, release the clutch slowly to avoid strong vibrations. Once the speed increases, quickly releasing the clutch will hardly cause any noticeable vibration.

Why is the tire pressure light on but the tires are fine?

The reason the tire pressure light is on but the tires appear fine could be due to either overinflated tires or prolonged driving with low tire pressure. Here are the details: 1. Overinflated tires: The tire pressure monitoring light may illuminate if a tire is punctured, causing a very slow leak, which can be checked with a tire pressure gauge. Sometimes, the light comes on because the tire pressure is too high. According to the international standard GBT2978-2008, the recommended tire inflation pressures are: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Therefore, if any tire exceeds 3.0 bar, it may trigger the tire pressure monitoring light. 2. Prolonged driving with low tire pressure: The tire pressure monitoring light may also come on if you drive for an extended period with low tire pressure. This usually happens when one tire has significantly lower pressure, causing it to heat up during high-speed driving, which in turn increases the tire pressure. In such cases, you should stop and rest or replace the tire with a spare immediately.

Are Hyundai and Kia the same company?

Hyundai and Kia are not the same company. Kia and Hyundai are two independent automobile manufacturers that operate separately, but both belong to the Hyundai Kia Automotive Group. Hyundai's vehicle lineup includes models such as the Elantra, Mistra, Tucson, Sonata, and Beijing Hyundai ix25. Kia's vehicle lineup includes models such as the Niro, K4, K3, K5, and KX7. Taking the 2020 Kia K5 Fashion Edition as an example, it is a mid-size 4-door 5-seater sedan with the following dimensions: length 4980mm, width 1860mm, height 1445mm, and a wheelbase of 2900mm. It is equipped with a 1.5T turbocharged engine and a 7-speed dual-clutch transmission, delivering a maximum power of 125 kW and a maximum torque of 253 Nm.
