Is making a U-turn on the sidewalk considered a traffic violation?

Making a U-turn on the sidewalk is considered a traffic violation. Legal basis: Article 49 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states that motor vehicles are not allowed to make U-turns at locations with no U-turn or no left-turn signs or markings, as well as at railway crossings, crosswalks, bridges, sharp curves, steep slopes, tunnels, or other sections of the road where it is prone to danger. Permitted situations for making a U-turn are as follows: Presence of U-turn signal or sign: When there is a U-turn signal at an intersection, a U-turn can be made when the U-turn signal is green; if there is a U-turn sign at the intersection or a U-turn marking on the lane, a U-turn can be made while ensuring the safety of oneself and others. No U-turn sign but left turns are allowed (no prohibition of U-turn signs or markings): Vehicles can make a U-turn at intersections where left turns are permitted and there are no prohibitions against U-turns. It is important to note that vehicles must proceed according to the left-turn lane signal without affecting the normal driving of other vehicles. If making a U-turn at an intersection with a left-turn waiting area, vehicles can first enter the left-turn waiting area when the straight signal is green and wait until the left-turn signal turns green to make the U-turn. U-turns are allowed at dashed lines: Whether it is a white dashed line or a yellow dashed line, U-turns are permitted. If it is a double yellow line with one solid and one dashed, check if the side you are on is the dashed line. If it is dashed, a U-turn can be made safely; if it is solid, a U-turn is not allowed. If encountering a double yellow line with one solid and one dashed at an intersection, a U-turn can be made on the dashed side, but you must not cross the stop line ahead. U-turns are allowed at yellow grid lines: Parking is prohibited in yellow grid line areas, but as long as there is no central barrier, a U-turn can be made here after yielding to normally moving vehicles. U-turns are allowed on the dashed side of a green belt: When the front of the green belt is a dashed line, vehicles on that side can make a U-turn from there. When the front of the green belt is a solid line, vehicles must follow the traffic signal, cross the crosswalk, and then make a U-turn. It is prohibited to make a U-turn by crossing the solid line or the crosswalk.

What is the steering angle matching channel number for the Volkswagen Lavida?

The steering angle matching channel number for the Volkswagen Lavida is 060. Overview of the steering angle sensor: The steering angle sensor is a device used to detect the rotation angle and direction of the steering wheel. Whether the steering wheel is turned left or right, the steering angle sensor will detect it, enabling the vehicle's electronic control unit to issue the correct steering command. The rotation angle of the steering wheel provides the basis for the vehicle's steering amplitude, ensuring the car moves according to the driver's steering intentions. Composition of the steering angle sensor: The steering angle sensor consists of photoelectric coupling elements, perforated slot plates, etc. The photoelectric coupling elements include light-emitting diodes and photosensitive transistors. The perforated slot plate is placed between the light-emitting diode and the photosensitive transistor.

What needs to be replaced for the 30,000 km maintenance of the Volkswagen Lamando?

For the 30,000 km maintenance of the Volkswagen Lamando, you need to replace the engine oil, oil filter, air filter, cabin air filter, and the vehicle's spark plugs. Introduction to car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Scope of car maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas. Purpose of car maintenance: To keep the car clean and in good technical condition, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life.

Why does the fuel consumption increase after replacing the spark plugs with Bosch ones in an Audi Q5?

Audi Q5's increased fuel consumption after replacing spark plugs is usually caused by excessive engine oil. Here are the details: Reasons for increased fuel consumption after replacing spark plugs: When replacing spark plugs, some car owners also change the vehicle's engine oil, which leads to increased fuel consumption. If the spark plugs are not tightened to the specified torque during replacement, it can cause gas leakage. As high-temperature and high-pressure gases slowly leak, the pressure in the cylinder decreases, resulting in higher fuel consumption. Precautions for replacing spark plugs: When using old spark plugs, efficiency is relatively low, and carbon deposits accumulate. Therefore, the ECU automatically adjusts to inject more fuel to ensure normal power output. If the spark plugs are replaced without disconnecting the power to reset the system, the engine continues to inject fuel in the previous manner, leading to increased fuel consumption.

What is the cylinder firing order of the Teana engine?

The cylinder firing order of the Teana engine is cylinders 1, 3, 5 on the left side of the crankshaft front and cylinders 2, 4, 6 on the right side. Below is the relevant content: Teana Engine: The Nissan Teana is equipped with the new QR25 engine and the new MR20 direct injection engine. The top of the valve lifter is coated with hydrogen-free diamond-like carbon, effectively reducing the friction coefficient between the camshaft and the lifter. The system continuously adjusts the opening time of the intake and exhaust valves and the ignition timing based on changes in engine speed, ensuring optimal intake and exhaust timing. Types of Engine Cylinders: Engine cylinders can be categorized by their arrangement into L-type (inline), V-type, H-type (horizontally opposed), and W12/16-type engines, among others. The engine displacement is equal to the sum of the working volumes of all cylinders. Increasing the number of cylinders can increase the engine displacement, enhance the engine's output power, and also make the engine run more smoothly, reducing vibration and noise.

What is the reason why the rear door cannot be opened after unlocking the T-Roc with the key?

The reason why the rear door cannot be opened after unlocking the T-Roc with the key is that there is a problem with the outer door handle cable or the door lock mechanism. The specific cause needs to be checked at a 4S shop or auto repair shop. Active working method: The principle is to control the door through the vehicle's electronic module and body control module. Simply press the key button to send an unlock/lock command, and after verification by the vehicle's electronic module, the door can be opened/closed. Coil induction working method: This mainly involves placing an encrypted chip inside the key. During the unlocking process, the vehicle's RF transceiver verifies whether the key matches to determine if the engine can be started. This is mainly used in special cases where the key battery is dead, allowing the car to still start normally.
