How to Determine if a Car is New When Buying?

Does driving onto the sidewalk count as running a red light?

If the vehicle stops at the crosswalk and does not continue driving, it is not considered running a red light but rather stopping beyond the line. The act of running a red light is clearly defined in the "Road Traffic Safety Law." Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. A red light is a traffic signal that prohibits passage. If a vehicle passes through an intersection when the light is red, it constitutes the traffic violation of running a red light. Running a red light refers to the act where the vehicle, while within the stop line, proceeds forward despite the traffic light being red, and both the front and rear wheels of the vehicle eventually cross the stop line. This is determined by capturing three photos via electronic cameras: A photo of the vehicle crossing the intersection stop line, showing the red light and license plate number. A photo of the vehicle completely crossing the stop line, showing the red light and license plate number. A photo of the vehicle continuing to move, comparing changes in the vehicle's position, showing the red light and license plate number. Capturing these three photos confirms the act of running a red light. Running a red light is not considered illegal under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other special vehicles. If caught on camera while yielding to such vehicles, manual review will not record the act as running a red light. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights. Photos of the violation may be blurry, and if you accidentally run a red light, the traffic police will not impose penalties. Emergency situations: If a citizen transports a patient in critical condition, they can provide proof from the hospital or the person being assisted to verify with the traffic police. If confirmed, the violation record can be cleared. If possible, it is best to call an ambulance to avoid traffic accidents caused by running a red light. Police direction: During peak commuting hours, traffic police may temporarily direct traffic at major intersections. Drivers must follow the gestures of the traffic police.

How often should the coolant be changed in a BMW 5 Series?

BMW 5 Series coolant should be changed every 2 years or 30,000 kilometers. Coolant has functions such as antifreeze, anti-boil, anti-scale, and anti-rust. Antifreeze is just one of its functions; it is not only used in winter but is required year-round. Under normal circumstances, engine coolant cannot be replaced with other liquids. The method for changing the antifreeze coolant in a BMW 5 Series is as follows: Open the car's engine hood, locate the coolant reservoir, follow the drain pipe to find the bottom drain screw, unscrew the bottom drain screw to allow the coolant to drain out from this hole. Once completely drained, reinstall the drain screw and add new coolant.

What is the function of the valve train?

The function of the valve train is to open and close the intake and exhaust valves of each cylinder at the right time, allowing fresh combustible mixture or air to enter the cylinder promptly and exhaust gases to be expelled from the cylinder in a timely manner. During the compression and power strokes, it ensures the sealing of the combustion chamber by closing the valves. Below is an introduction to the valve train: 1. The valve train is the mechanism that controls the intake and exhaust of the engine. It regulates the intake and exhaust of the combustion chamber according to the working cycle and ignition sequence of each cylinder, including the intake volume, intake timing, and exhaust timing, thereby adjusting and organizing combustion based on these conditions. 2. Components of the valve train: The valve train consists of two groups—the valve drive group and the valve group. The valve drive group includes the crankshaft timing gear, camshaft timing gear, camshaft, tappet, pushrod, rocker arm, valve clearance adjustment screw and lock nut, and rocker arm shaft. The valve group includes the valve, valve guide, valve spring, valve spring seat, valve oil seal, and valve seat, among others.

What are the differences between the URV and the Crown Road?

The differences between the URV and the Crown Road are as follows: 1. Different body dimensions: The URV has a length, width, and height of 4825mm, 1942mm, and 1670mm respectively; the Crown Road has a length, width, and height of 4816mm, 1942mm, and 1669mm respectively. 2. Different taillights: The URV features a full-width taillight design, while the Crown Road has C-shaped taillights. 3. Different 0-100km/h acceleration times: The URV accelerates from 0 to 100km/h in 10.1 seconds, while the Crown Road takes 10.2 seconds. The following are the similarities between the URV and the Crown Road: Both the URV and the Crown Road are equipped with a 2.0L turbocharged engine, producing a maximum horsepower of 272PS, a maximum power of 200kW, and a maximum torque of 370Nm.

What is the S gear in an automatic transmission car?

Automatic transmission S gear is the sport mode, which can also be used for overtaking while driving. Here are some relevant introductions about the S gear: 1. The S gear has three sub-gears, namely 1, 2, and 3. These gears can be switched when the car is overtaking or climbing a hill to obtain greater power. 2. The S gear allows the car to have sufficient driving pleasure like a manual transmission car, but this gear consumes a lot of fuel when in use. It's like the car is constantly stepping hard on the accelerator. The S gear should not be used during startup or high-speed driving. Using the S gear during startup does not significantly increase speed; instead, it may cause speed issues due to gear problems, wasting more power.

What tires does the Infiniti Q50 use?

Infiniti Q50 uses 225/55r17 and 245/40r19 tires. In 225/55r17, 225 represents the tire width of 225 millimeters, 55 indicates the aspect ratio of 55, r stands for radial tire, and 17 means it can be installed on 17-inch rims. The following are the functions of tires: 1. Support the entire weight of the vehicle and bear the load of the car. 2. Transmit traction and braking torque to ensure the adhesion between the wheels and the road surface. 3. Reduce and absorb the vibration and impact force during driving, preventing severe vibration and early damage to car components.
