A small wrench symbol inside a car is a maintenance reminder indicator, signaling that the vehicle is due for servicing. This maintenance reminder is part of the car's built-in maintenance alert system. After each service, the system resets the mileage and time counters for the next maintenance. When the vehicle reaches the preset values, the maintenance reminder will appear on the dashboard. Vehicles without an onboard computer will display a small wrench symbol. If the car has been properly serviced and the wrench symbol still appears, it can be manually reset using the following method: 1. Insert the key into the ignition, but do not turn it; 2. Press and hold the trip meter reset button for 5 to 10 seconds, then turn the key to the 'on' position.

Last time when I got my car repaired, the mechanic specifically taught me that when the small yellow wrench icon lights up on the dashboard, it's a maintenance reminder. The car's computer calculates either by mileage or time interval—for example, my car triggers this symbol every 8,000 kilometers driven. Don’t panic; it simply means it’s time to change the engine oil and oil filter, not that the car is broken. If the light stays on right after a service, just ask the mechanic to reset it with a diagnostic tool. However, if you see it flashing red or accompanied by other warning lights, you should head to the workshop immediately for a check-up.

How to distinguish between internal and external circulation in Citroen C4L?

Light on the left indicates internal circulation, light on the right indicates automatic mode, and no light indicates external circulation. Below are detailed explanations about it: 1. Explanation one: Internal circulation draws air from inside the car and exhausts it inside, while external circulation draws air from outside the car and exhausts it outside. 2. Explanation two: Internal circulation only adjusts the limited air inside the car, making it energy-saving. However, prolonged internal circulation will increase the proportion of carbon dioxide and decrease the proportion of oxygen in the car. 3. Explanation three: Materials such as plastics, rubber, fabrics, paints, coatings, insulation materials, and adhesives in the car can emit harmful gases like formaldehyde, benzene, styrene, acetaldehyde, and acrolein, which can cause dizziness and fatigue for passengers.

Why is the windshield washer nozzle spraying weakly and not reaching high?

The reason why the windshield washer nozzle sprays weakly and does not reach high is that the nozzle is clogged or the motor inlet in the water tank is blocked, or the motor may be damaged. Here is some extended information: 1. Columnar nozzle: Since the columnar nozzle is set in the external spraying device and is visible to the naked eye, high-pressure water gun washing and scale residue during car washing can cause slight changes in the nozzle angle. This may likely cause the spraying angle to deviate from the correct trajectory, which is why some vehicles spray water off-target. 2. Mist nozzle: Unlike the columnar nozzle, the mist nozzle evenly sprays water droplets or mist, and the spraying area is larger than that of the columnar nozzle. The mist nozzle is preset before the vehicle leaves the factory, and the internal shower head disperses the water column. Therefore, if there is a problem, it cannot be adjusted by oneself and must be repaired at a professional repair shop.

Is Running a Yellow Light a Violation?

Running a yellow light is considered a traffic violation. Below is an introduction to traffic signal-related information: Signal Light Composition: Traffic signal lights are lights that direct traffic flow, generally consisting of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to proceed, and a yellow light serves as a warning. Signal Light Classification: Traffic signal lights are categorized into motor vehicle signal lights, non-motor vehicle signal lights, pedestrian crossing signal lights, directional indicator lights (arrow signal lights), lane signal lights, flashing warning signal lights, and railway crossing signal lights. Lighting Rules: When the red light is on, vehicles are prohibited from going straight or turning left, but right turns are permitted if they do not hinder pedestrians or other vehicles. When the green light is on, vehicles are allowed to proceed straight or turn. When the yellow light is on, vehicles must stop at the stop line or within the pedestrian crossing line if they can do so safely; otherwise, they may continue through. A flashing yellow light warns vehicles to proceed with caution.

How many years can a National III standard family car be driven?

There is no exact time limit; it is determined based on the mileage of the vehicle. When the vehicle reaches 600,000 kilometers, it will be guided to be scrapped. During this period, the vehicle must undergo an annual inspection every year. As long as it passes the inspection, the National III standard vehicle can be driven normally on the road. More relevant information is as follows: 1. Vehicle restrictions: Some regions in China have already implemented restrictions on National III standard vehicles, clearly stipulating that National III emission standard motor vehicles are not allowed to enter. After this policy was introduced, it became very unfavorable for National III standard vehicles. Even if the vehicle can pass the normal annual inspection, there are many places where it cannot enter. Forced entry is possible but will result in corresponding penalties. 2. Penalties: These include deductions from the motor vehicle driving license and fines. Over time, more and more places will impose restrictions on National III standard vehicles.
