Automatic transmission cars typically start between 1500-2000 RPM, which is both fuel-efficient and smooth, causing no damage to the engine. Automatic transmission vehicles have their own idle speed. There's no need to press the accelerator when starting, and as long as the RPM doesn't exceed 2000, it's considered normal. Here are some related details about automatic transmissions: 1. There are certain usage requirements and techniques for automatic transmissions. When shifting gears in an automatic vehicle, shift to 2nd gear when the speed reaches 20 km/h and the RPM is between 1500-2000. Shift to 3rd gear when the RPM exceeds 2000, which is close to 30 km/h. Similarly, shift to 4th gear when the speed reaches 50 km/h. This is because shifting at 2000 RPM can easily cause carbon buildup, so the fuel-efficient and suitable RPM range is between 1500-2000 RPM. 2. For a new automatic transmission car during the initial break-in period, it's best not to exceed 2200 RPM. During the mid break-in period, avoid exceeding 3000 RPM, and it's also recommended not to exceed 3000 RPM during the later break-in period.

How many points will be deducted and how much will be fined for a 5-seater car overloaded with 2 people?

A 5-seater car overloaded with 2 people is considered to be overloaded by more than 20%, which will result in 3 points deducted and a fine. For non-operational small passenger cars carrying passengers exceeding the approved number by less than 20%, 2 points will be deducted and a fine will be imposed; for exceeding 20% or more, 3 points will be deducted and a fine will be imposed. The following are the hazards of overloading: Shortening the service life of the car and accelerating the aging of parts: Overloading will change the original design data. For example: loose rivets, tightened screws falling off, welding points breaking, and overall frame deformation. Overloading shortens the service life of the vehicle and accelerates the aging of rubber and plastic parts. Accelerating tire wear and changes: Car tires are designed and produced based on the total weight of the car, with a considerable safety factor. However, when the car is overweight, the tires will be overloaded and deformed. At the same time, increased friction will also lead to a shorter tire life. According to measurements, when overloaded by 20%, tire life is reduced by 30%; when overloaded by 40%, tire life is shortened by 50%. Accelerating engine damage: Overloading the car causes great damage to the engine. First, the load increases and the power is insufficient. Long-term low-speed driving leads to engine overheating and aggravates the damage of parts. At the same time, it also increases fuel consumption and transportation costs. Heavy steering and increased centrifugal force affect the car's handling performance: Overloading will increase the centrifugal force when turning, which will affect the stability of the car and reduce the possibility of accidents. Reducing braking performance and increasing the non-safety zone distance: There are many factors that affect the braking distance of a car, among which the change of the car's load will directly affect the length of the braking distance. When a loaded car brakes, the load tilts forward, the front wheel load increases, and the rear wheel is the opposite. This changes the ground adhesion and consequently the braking distance. The deceleration of a fully loaded car is less than that of an empty car. Shortening the life of the spring steel plate: reducing the vehicle's passing ability. Due to overloading, the spring steel plate is overloaded, and continuous rebound during operation shortens its life. Due to excessive load, the car body sinks as a whole, reducing the distance from the ground and the car's passing ability.

Where to Adjust the Remote Key Lock Sound?

Remote key lock sound cannot be adjusted. If there is sound, it cannot be turned off; if there is no sound, it cannot be turned on. Here is some information about remote keys: 1. Almost all cars have remote keys, which can be used to unlock and lock the doors, making it very convenient. 2. Some cars will sound the horn once when the doors are locked, while others will not. 3. However, all cars will flash the hazard lights when the doors are locked or unlocked, which serves as a reminder to the owner that the doors have been unlocked or locked.

What Are the Functions of Transmission Fluid?

Here are the functions of transmission fluid: 1. It keeps the gear system clean, ensuring the normal operation of the transmission and extending the service life of the transmission device. It provides effective lubrication even at low temperatures and reduces fluid loss under harsh operating conditions. 2. Automatic transmission fluid is specifically designed for automatic transmissions. Due to significant differences in working conditions and technical requirements, using engine oil as automatic transmission fluid was quickly phased out. 3. The specialized automatic transmission fluid used today serves as both the hydraulic fluid for the torque converter and the lubricating oil for the planetary gear structure, as well as the hydraulic fluid for the shifting mechanism.

Does stepping on the foot brake stop or go?

Stepping on the foot brake stops the vehicle. Here are the specific details about the foot brake: 1. Foot brake position: The foot brake is located near the left foot. 2. Working principle: The foot brake in cars is entirely hydraulic, acting on all four wheels. In the case of front disc and rear drum configurations, the front wheels have a greater effect. Since the foot brake is a hydraulic system, it provides strong force and good performance. However, if the hydraulic system malfunctions, the brake may fail. 3. Usage method: Press the pedal down firmly with your left foot to activate it. Pressing it again firmly and then releasing it will disengage the parking brake.

What is the transmission model of the Tiguan L?

The Tiguan L's 1.4T model is equipped with the DQ250 6-speed wet dual-clutch transmission, while other models use a 7-speed dual-clutch transmission. The 2.0T low-power version engine is paired with the DQ380 transmission, and the 2.0T high-power version uses the DQ500 transmission. The dual-clutch transmission, also known as the direct-shift gearbox, is unique in that it shifts gears faster than other transmissions, delivers greater torque, and operates more efficiently. The dual-clutch transmission can be shifted manually or automatically, offering easier control and higher power transmission compared to traditional automatic transmissions, while also responding faster than manual transmissions.
