What does the S gear in an automatic transmission car represent?

S gear stands for Sport mode. When the gear is shifted to S position, the transmission can shift freely, but the shifting timing is delayed, keeping the engine at high RPM for a longer period. This allows the car to operate at lower gears with higher RPM for extended durations, resulting in greater torque output and acceleration. Here is more information about S gear: 1. Due to its powerful performance, S gear is typically used when overtaking or climbing hills. After completing these maneuvers, it's advisable to switch back to the more economical D gear, as S mode consumes significantly more fuel due to increased fuel injection at high RPM. It also causes more wear on the transmission and isn't necessary for daily driving. 2. Although S gear isn't used frequently, it does have benefits for the vehicle. Cars that often drive in congested urban areas tend to accumulate more carbon deposits in the engine. Periodically using S gear helps remove these deposits, improving fuel economy and extending engine life.

What is the best mileage for the first car maintenance?

New car first maintenance is at three months or 5,000 kilometers, whichever comes first. The items for the first car maintenance include the following: 1. Change the engine oil and oil filter. Since the period before the first maintenance is the running-in period of the vehicle, the gradually running-in engine will mix mechanical impurities such as dust, metal wear, and carbon deposits into the engine oil during operation. Changing the engine oil and oil filter during the first maintenance is crucial. If the debris and impurities generated by the engine operation are not removed in time, it may cause abnormal damage to the internal parts of the cylinder. 2. Tighten the nuts. During the first maintenance of a new car, the nuts in various parts of the car should be checked. This is because many vehicles leave the factory with some screws not particularly tight. During the first maintenance, the screws will be tightened according to the specified torque. 3. Chassis inspection. During the first maintenance, the car will be lifted to check the chassis for scratches, bottoming, corrosion, oil leakage, etc. 4. Tire inspection. Mainly check whether the tire wear is consistent. If the wear is severe, it means the vehicle may have a tendency to deviate. In addition, tire pressure should be checked and appropriately supplemented. 5. Computer system check. Through the computer system check, car problems can be comprehensively detected.

How Often Should Clutch Plates Be Replaced?

Automobile clutch plates do not have a fixed replacement cycle. Their service life is largely related to the driver's habits and road conditions. Generally, clutch plates are replaced every 100,000 kilometers. The following situations indicate that the clutch plates need to be replaced: 1. When the vehicle is parked and does not stall during a hill start: First, park the vehicle, engage the handbrake, start the engine, and shift into second gear to simulate a hill start. Gently press the accelerator while slowly releasing the clutch. Normally, the vehicle should stall immediately. If the vehicle hesitates for 3 to 5 seconds before stalling or does not stall at all, it indicates that the clutch plate is worn thin and is slipping. 2. Severely worn clutch plates, due to poor engagement and slipping, will cause a lag in the matching between the engine and transmission, with the RPM dropping very slowly. 3. While driving, shift into fourth gear and release the clutch. If the RPM takes more than 2 seconds to drop, it's a sign of clutch plate wear.

What Causes the Oil Light to Illuminate When There Is Oil?

The following are specific reasons why the oil light may illuminate even when there is oil: 1. False fault alarm: A false fault alarm mainly refers to a malfunction of the oil pressure sensor—the oil pressure sending unit. This means the sensor itself, which is designed to monitor the engine oil pressure, fails. 2. Engine sludge: Engine sludge can sometimes be related to the oil light illuminating. It's quite straightforward: large impurities formed by engine sludge can easily clog the oil pump screen (oil pickup) in the oil pan, leading to low oil pressure. Additionally, engine sludge can cause the oil to degrade or change in viscosity. If the oil viscosity becomes too high, it may also trigger the oil light alarm.

Can a puncture on the side of a tubeless tire be repaired?

A puncture on the side of a tubeless tire can be repaired if the hole is smaller than 6 millimeters. Below are some relevant tips for car tire maintenance: 1. Regularly check tire pressure: Inflate underinflated tires promptly to maintain consistent tire pressure. Otherwise, it can lead to rapid wear of low-pressure tires, increased driving resistance, higher fuel consumption, and even cause issues like directional deviation. 2. Avoid hitting obstacles: When driving at high speeds, hitting obstacles such as potholes can cause severe compression deformation between the obstacle and the tire near the wheel rim flange. This may damage the tire's internal fabric cords, leading to air leakage and the formation of bulges. In severe cases, it can cause the tire sidewall to rupture, resulting in sudden tire deflation.

How to Change from Gasoline Vehicle Lottery to Electric Vehicle Lottery?

In the configuration indicator function area, directly locate the application form and click on the 'Switch Indicator Type' option at the top. Below is relevant information about the vehicle lottery: 1. New Energy Vehicle Lottery Rules: The indicator management for new energy passenger vehicles implements a 'separate configuration' with its own lottery pool. The qualifications for obtaining a new energy vehicle indicator are basically the same as those for the traditional lottery, but the buyer must promise or confirm that they have the conditions to install charging facilities. 2. Changes in Vehicle Lottery Indicator Configuration Frequency: The application period has been adjusted from monthly to a concentrated application period from January 1 to March 8 and August 1 to October 8 each year; the number of annual configurations has been changed from 6 times to 3 times, with new energy indicators allocated in May, and ordinary indicators allocated in June and December.
