What does the circle with an exclamation mark on the car dashboard mean?

Red exclamation mark (specifically a circle with an exclamation mark inside parentheses), this represents a warning for the braking system, mainly indicating a brake system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system are required to avoid accidents. Apart from the red exclamation mark indicating a brake system fault, other exclamation marks on the car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a general performance or component and function fault in the car. Main issues include parking sensor faults, fuel cutoff system intervention or malfunction, external light faults, engine oil pressure sensor faults, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission fault or transmission lubricant level below the normal range. Transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line under parentheses with an exclamation mark in the middle. This represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will illuminate. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in one of the car lights. Solution: Go to a 4S shop for inspection and repair as soon as possible, or perform a self-check. Focus on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the problem.

That circle with an exclamation mark in the middle on the car dashboard suddenly lit up, and I encountered it once on the highway. I immediately slowed down and pulled over to a safe area. That’s the brake system warning light, usually indicating an issue with the brakes. Common causes include low brake fluid or a malfunctioning ABS (Anti-lock Braking System). That time, I popped the hood and checked the brake fluid reservoir, finding the level below the minimum line. After topping it up with fresh brake fluid, the light went off. But don’t take it lightly—if the brakes fail, the consequences can be serious. I’ve since made it a habit to check the brake fluid level monthly; prevention saves trouble on the road. After parking, test the brake pedal resistance—if it feels spongy, be extra cautious and head to a professional repair shop ASAP. If you can’t remember what the icons mean, downloading a car app or checking the manual is always a safe bet. Protecting yourself and others is what matters most.

How to Check the Production Date from Car Glass?

Here's how to check the production date of car glass: 1. The number represents the production year of the glass, indicating the last digit of the year. 2. The black dots indicate the production month of the glass. Some glass has dots before the number, while others have dots after the number. 3. If the dots are before the number, subtract the number of dots from 7; if the dots are after the number, subtract the number of dots from 13. The result is the production month of the glass. 4. Some glass may also have a few thick black dots added before the production year and month, which are used to specify the week of the month.

How Often Should Brake Pads Be Replaced?

There is no fixed interval for replacing brake pads, as it depends on driving conditions and habits, which can affect the wear of brake pads. The following situations indicate when brake pads need to be replaced: 1. Regularly check the thickness of the brake pads. If the thickness is less than 3mm, it's time to replace them. 2. When the dashboard displays a brake pad warning message, it indicates that the brake pads need to be replaced. 3. If the car shifts or drifts when braking, it suggests that the brake pads are worn and need replacement.

What are the symptoms of timing chain skipping teeth?

If the engine timing chain is not regularly maintained and adjusted, timing belt skipping may occur, leading to issues such as difficulty starting the engine and poor acceleration. The main causes of timing chain skipping teeth are as follows: 1. The belt comes into contact with oil: Since the timing belt is a rubber component, it should be kept clean during use and maintenance. If it comes into contact with oil or other solvents, the belt can corrode and deform, causing slippage and skipping teeth. 2. Failure to promptly inspect and adjust the timing belt tension: After a certain mileage, the timing belt naturally stretches. If the tension is not adjusted in time, skipping teeth can easily occur.

How Long Should You Wait Between Subject 3 and Subject 4 Exams?

After passing Subject 3, the timing for taking Subject 4 falls into three scenarios: taking it directly on the same afternoon; within 9 days without an appointment—you can take the Subject 4 exam at the designated location within 9 days after passing Subject 3 by presenting your ID; or scheduling after 10 days, where the success of the appointment depends on the current number of examinees, the priority of the student, and temporary arrangements at the test center. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. It includes requirements for safe and civilized driving operations, knowledge of safe driving under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. Subject 4 Exam Notes: Exam Duration: The exam lasts 30 minutes, and making mistakes totaling 12 points (6 questions) will terminate the session. Number of Questions: Depending on the type of driver's license being tested, 50 questions are proportionally selected from the corresponding Subject 4 question bank—800 questions for car licenses and 1,023 for large vehicle licenses, with each question worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions. The first 45 questions are single-choice, and the last 5 are multiple-choice. The exam also features animation questions, image-based questions, scenario recognition questions, and text-based questions. Retake Notes: Failing Subject 4 only requires retaking Subject 4. The driving school schedules the retake, with no limit on the number of attempts, and no additional fees are required for retakes. Subject 4 Exam Tips: Strengthen weak areas by identifying the reasons for mistakes. For marked questions, avoid merely memorizing the correct answers. Instead, consult regulations, textbooks, or reference materials to understand and internalize the reasons behind the errors. Categorize and summarize questions by referring to the question bank's analysis to find similar questions. Many questions in the bank are similar and easily confused, so it's essential to analyze and group them. For example, traffic signs for walking, hiking, pedestrian crossings, and pedestrian warnings have similar patterns and can be confusing. Grouping them during study helps avoid mistakes. Use memory techniques: Many questions involve numbers, which can be summarized for easier recall. The driving test consists of three main subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 4 is the colloquial term for the Subject 3 Safety and Civilized Driving Knowledge Test and is not a separate subject. Subject 1 covers road traffic safety laws, regulations, and related knowledge; Subject 2 is the field driving skills test; and Subject 3 includes road driving skills and safety and civilized driving knowledge. The Safety and Civilized Driving Knowledge Test is conducted after Subject 3.

Causes of Compressor Abnormal Noise?

If abnormal noise occurs from the compressor after turning on the air conditioning, it is usually caused by internal piston wear or valve plate damage; if the compressor makes abnormal noise without the air conditioning on, it is mostly due to damaged compressor bearings. Below are some introductions about the compressor: 1. The car air conditioning compressor is the heart of the car air conditioning refrigeration system, responsible for compressing and delivering refrigerant vapor. 2. Depending on the working principle, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors. 3. Based on the working method, compressors can generally be categorized into reciprocating and rotary types, with common reciprocating compressors including crankshaft connecting rod type and axial piston type, and common rotary compressors including rotary vane type and scroll type.
