CVT transmission refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between a CVT and a stepped transmission is that its gear ratio is not a discontinuous point but a series of continuous values, thereby achieving excellent fuel economy, power performance, and smooth driving experience, while also reducing emissions. In a CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft connects to the smaller pulley, which drives the larger pulley through the steel belt. Theoretically, a CVT transmission system can have an infinite number of gear ratios, allowing for more flexible gear settings. It is easier to achieve a balance between gear ratios, speed ratios, performance, fuel consumption, and exhaust emissions compared to traditional transmission systems.

What to Do When the Push-to-Start Steering Wheel Locks and the Car Won't Start?

The solution for when the push-to-start steering wheel locks and the car won't start: You can gently shake the steering wheel with your left hand while simultaneously turning the key with your right hand to unlock the car. The car's security system includes an automatic steering wheel lock function to prevent theft. The push-to-start system operates using radio frequency identification (RFID) technology, which automatically unlocks the car doors by sensing the chip in the key fob carried by the driver. It also allows the car to be started with the push of a button by recognizing the key fob's chip. Smart keys are a common feature in keyless entry systems, utilizing advanced radio frequency technology and sophisticated vehicle identification coding. When the driver touches the door handle, sensors detect the signal from the smart key and automatically unlock the doors.

How to Open the NIO Charging Port?

The NIO charging port is designed on the fenders on both sides. Simply press the upper right corner of the cover, and it will slowly open. The left side is for slow charging, while the right side is for fast charging. Below is an introduction to NIO vehicle charging: Using Public or Home Charging Stations: You can download various charging apps on your phone and locate charging stations through the app. Then, insert the charging gun into NIO's charging port to start charging. NIO supports fast charging. If you want to save time, you can use fast charging stations, which typically take about 40 minutes to charge up to 80%, making it quite convenient. Visiting a Battery Swap Station: NIO supports battery swapping. You can find the nearest battery swap station via the NIO vehicle system and drive the car into the station. The station will lift the vehicle, automatically remove the old battery, and replace it with a new one with over 80% charge. The entire process takes about 10 minutes. Currently, the number of NIO battery swap stations is limited, mainly concentrated in first-tier cities, so this feature may not be available in second- or third-tier cities. Using Mobile Charging Vehicles: NIO provides mobile charging vehicles, but they are intended for emergency charging. If your vehicle runs out of power on the road, you can call NIO Power to come and charge it. It takes about 10 minutes to restore a range of 100 kilometers.

What is the reason why the rear seat light of the Golf cannot be turned off?

The reasons why the rear seat light of the Golf cannot be turned off are: 1. The switch is malfunctioning; 2. There is a fault in the car light circuit; 3. The vehicle's door was not closed tightly when getting off. The car light has three modes: ON is the constant-on mode. When this switch is turned on, the roof light will stay on continuously and will not turn off even after the car is locked. DOOR mode means the light only turns on when the door is opened. OFF is the off mode. When this mode is selected, the roof light remains off and will not light up. The Golf is a classic hatchback compact family car launched by FAW-Volkswagen. In terms of body dimensions, it has a length of 4199mm, a width of 1786mm, a height of 1479mm, and a wheelbase of 2578mm.

Drive the vehicle to the vehicle management office with your driver's license, ID card, vehicle registration certificate, and valid compulsory traffic insurance policy for the current year; 2. Fill out the motor vehicle annual inspection application form at the vehicle management office, then submit the form and other materials to the staff and pay the inspection fee; 3. After payment, the staff will conduct an exterior inspection and on-site vehicle inspection (prepare a fire extinguisher and warning triangle). After the inspection, collect the inspection certificate at the designated window; 4. Take the certificate to the designated window to receive the annual inspection sticker and environmental protection inspection pass sticker, completing the vehicle inspection process.

What Components Make Up an Automotive Braking System?

An automotive braking system consists of four main components: the energy supply device, control device, transmission device, and brake. It is a specialized set of devices designed to forcibly reduce a vehicle's speed, with primary functions including decelerating or stopping a moving vehicle, maintaining stable speed for downhill driving, and keeping a stationary vehicle immobile. The automotive braking system includes two independent sets of devices: the service brake system and the parking brake system. The service brake system is operated by the driver using their foot, hence it is also called the foot brake system; the parking brake system is operated by the driver using their hand, hence it is also called the hand brake system. In emergency situations, both braking systems can be used simultaneously to enhance the vehicle's braking effectiveness.

What does 10w40 engine oil mean?

10w40 engine oil refers to an oil with a kinematic viscosity of 14.5cst at 100°C. The '10' indicates that the oil is suitable for low temperatures down to -25°C, 'w' stands for winter, and '40' represents the high-temperature viscosity of the oil. The number before 'w' indicates the oil's low-temperature fluidity—the smaller the number, the better the fluidity at low temperatures. The number after 'w' represents the oil's viscosity grade at 100°C—the higher the number, the better the protection the oil provides to the engine at high temperatures. Lubricating oil must have sufficient viscosity to prevent wear between moving parts and to form an oil film between them at various operating temperatures. Higher viscosity is not always better; the choice of oil should be based on the temperature range during use, and a lower viscosity oil should be selected whenever possible.
