If the car cannot start, call for roadside assistance or tow the car to the nearest repair shop for inspection and repair; 2. If the car can operate normally without any additional abnormalities, try restarting the car; 3. If the car exhibits symptoms like loss of power during acceleration or unusual engine noises after the yellow light comes on, stop driving immediately.

Why does a car stall?

Cars can stall for the following specific reasons: 1. Insufficient engine power: Stalling occurs when the engine doesn't provide enough force to move the car forward, causing the engine to be forced to stop. 2. Engine unable to rotate: The engine must rotate continuously during operation. If it cannot rotate, it will stop and require the electric starter motor to restart. 3. When in first gear: Gradually releasing the clutch is fine, but suddenly releasing it completely may cause the engine to stop because its output force can't overcome the starting friction. 4. Whether stalling occurs when shifting to fourth gear below 20km/h depends on the car's performance. High-horsepower cars might not stall, as this situation is like asking a 100-meter sprinter to run wearing military cross-country gear - high speed makes it difficult to bear the load. 5. Deceleration depends on circumstances: Generally above 40km/h, just applying the brakes is sufficient. At low speeds around 20km/h, you should press the clutch, otherwise the car may stall when speed decreases.

What is the normal range for SUV tire pressure?

SUV tire pressure between 2.2 to 2.5 bar is considered normal. Different vehicle models have varying weights and tire specifications, leading to different manufacturer-recommended standard tire pressures. The recommended tire pressure is usually displayed on the door frame or fuel tank cap. If unsure, always follow the manufacturer's recommended value for inflation. Whether it's an SUV or a sedan, each vehicle's matched tires have corresponding tire pressures, and the specific standard tire pressure for each vehicle should be followed. Typically, the front tire pressure ranges from 2.2 to 2.3 bar, while the rear tire pressure ranges from 2.4 to 2.5 bar. The tire pressure of all four tires does not necessarily have to be identical. Tire pressure directly affects tire performance and responsiveness, and to some extent, it also influences fuel consumption.

How to Conduct Annual Inspection for Vehicles Exempt from Inspection for Six Years?

The method for annual inspection of vehicles exempt from inspection for six years: The owner needs to submit the vehicle license, tax payment or tax exemption certificate for vehicle and vessel tax, the ID card of the vehicle owner, and the valid compulsory traffic insurance policy to the vehicle management office before the annual inspection deadline. If the process is delegated to someone else, the original ID card of the agent and a written power of attorney signed by the vehicle owner must also be provided, after which the owner can wait for the review results. The six-year exemption from inspection does not mean that no annual inspection is required for six years, but rather that no on-site inspection is required during this period. The inspection of documents such as the vehicle license and insurance policy is still required every two years. Additionally, with the convenience of the internet nowadays, owners can also handle the process online. They can apply on the website or official account of the local vehicle management office, fill in the relevant information, and then follow the process prompts to upload photos of required documents such as the vehicle license and compulsory traffic insurance policy, or send the relevant materials by courier for door-to-door collection. Once approved, the inspection qualification mark will be sent back by courier, with only the round-trip shipping costs to be paid.
