The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard with exclamation marks, such as the tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, brake system fault light, transmission fault indicator light, and wiper fault indicator light. The following is a detailed introduction to the exclamation mark fault lights: General faults: A triangle with an exclamation mark inside. If this symbol lights up, it means that the general performance or components and functions of the car have failed. Mainly includes parking sensor failure, fuel cut-off system intervention or failure, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to the 4S shop for inspection and find out 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 that there is a fault in the transmission or the transmission lubricating oil is below the normal range. The transmission oil needs to be replaced in time. Brake system fault: An exclamation mark in the middle of a bracket and a circle. This represents a warning of the brake system, mainly including brake system failure and low brake fluid level. The brake system needs to be repaired immediately to avoid accidents. Abnormal tire pressure: An exclamation mark in the middle of a horizontal line under a bracket. This represents the tire pressure monitoring warning light. When the tire pressure of the car is too low, this warning light will light up. It is necessary to check the tire pressure of the car and restore the tire pressure to the normal range. Lighting fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating that there is a fault in the car lights. Solution: Go to the 4S shop for inspection and treatment as soon as possible, or you can check it yourself. Focus on checking commonly used bulbs such as turn signals, fog lights, and interior lights to find out where the problem is. In addition, in the process of daily use of the vehicle, the fault lights displayed in the vehicle dashboard will be divided into two different colors, yellow and red: Yellow indicates that there is a fault in the corresponding system, but the problem is not very serious. It is necessary to slow down and proceed to the corresponding maintenance point for repair to eliminate potential safety hazards in time. Red indicates that there is a very serious problem in the corresponding system. In this case, do not continue driving. You should stop the car in time and call for professional help to prevent unpredictable dangers to the vehicle and personal safety caused by forced driving. It should be noted that when the car is ignited and started, all lights will light up, and the system will perform automatic detection. After the detection is completed, the lights will automatically go out. If a light does not light up or stays on when the ignition switch is turned on, or lights up while driving, it means that the related system has a fault. In such cases, professional help should be sought in time for car inspection and elimination of potential safety hazards.

What are the new regulations for small vehicle annual inspections in 2020?

New regulations for vehicle annual inspections: Starting from November 20, 2020, non-operational small and micro passenger vehicles with 7-9 seats (excluding minivans) within 6 years are included in the exemption scope; for non-operational small and micro passenger vehicles (excluding minivans) over 6 years but under 10 years, the inspection cycle is relaxed from once a year to once every two years. This means private cars only need to undergo two on-site inspections within 10 years, specifically in the 6th and 8th years. Annual inspection content: Check whether the engine, chassis, body, and auxiliary equipment are clean, complete, and functional, whether the paint is uniform and aesthetically pleasing, whether major assemblies have been replaced, and whether they match the initial inspection records; Verify whether the vehicle's braking performance, steering control, lighting, exhaust, and other safety features comply with the "Technical Conditions for Safe Operation of Motor Vehicles"; Check whether the vehicle has been modified, altered, or reconstructed, whether the driving license, license plate, and vehicle records match the actual condition, whether there are any changes, and whether approval and modification procedures have been completed; Inspect whether the license plate, driving license, and enlarged license plate markings on the vehicle are damaged, altered, or illegible, and whether replacement is needed; For large vehicles, check whether the unit name or the street, township, or town name and the seating limit in the cab are spray-painted in Chinese imitation Song font on both sides of the door as required; For trucks, check whether the rear tailgate (including the trailer's rear tailgate) exterior is spray-painted with the vehicle number enlarged 2-3 times as required, and for individual or joint-operation vehicles, whether the word "individual" is spray-painted on both sides of the door. The characters must be clear, and no unit codes or other patterns are allowed (special cases require approval from the vehicle management office).

Does Vehicle Damage Insurance Include Glass Insurance?

Vehicle glass insurance generally does not apply to the various deductible rates and deductible amounts specified in the main insurance. Vehicle glass insurance is an additional coverage to vehicle damage insurance, and the actual premium is not high. For comprehensive protection of the vehicle, it is advisable to add vehicle damage insurance, especially if the vehicle has expensive imported glass. Here is additional information: 1. Insurance Tips: Purchasing standalone glass breakage insurance is like buying insurance for your car's "face," which is very important. Therefore, standalone glass breakage insurance is also a very commonly used type of additional coverage. Many car owners habitually think that standalone glass breakage falls under the scope of vehicle damage insurance. In fact, if you file a claim with the insurance company without having purchased standalone glass breakage insurance, you will not be compensated. 2. Notes: The so-called standalone glass breakage insurance means that if the vehicle's windshield or window glass breaks independently while the vehicle is parked or in use, and no other parts are damaged, the insurance company will be responsible for compensation.

What does it mean to release the handbrake?

Releasing the handbrake refers to the action of disengaging the mechanical handbrake when starting the car, otherwise it can easily cause wear and tear on the brake system hardware and lead to the car stalling. Generally speaking, driving with the handbrake engaged causes more damage to the brake components the faster the speed, and it can also cause some damage to the tires. Below is some related information: 1. Parking Brake: Commonly known as the handbrake, its function is to provide resistance to the car when parked, preventing it from rolling. The parking brake, whether manual or the parking gear in an automatic transmission, locks the drive shaft or rear wheels. The force applied by the parking brake is much less than that of the service brake, just enough to prevent the car from rolling on a slope. 2. Auto Hold Function: Traditional handbrakes require the driver to manually release the brake or skillfully coordinate the throttle and clutch for a smooth start on a slope. The AUTOHOLD auto hold function, however, uses a slope sensor to provide precise braking force through the controller. During startup, the parking control unit calculates information from sensors such as the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. When the driving force exceeds the rolling resistance, the parking brake is automatically released, allowing the car to start smoothly.

Will the rim be damaged if I continue driving after a tire blowout?

If a regular tire blows out, you should not continue driving. Continuing to drive on a blown-out tire can cause more severe tire damage, making it irreparable, and may also lead to rim deformation. Rim deformation depends not only on the distance driven but also on the speed. Generally, if you drive slowly for about 100 meters after a blowout, the rim will not be damaged. However, if you drive a long distance or at high speed, it not only poses significant safety hazards but may also require replacing both the tire and the rim, resulting in higher costs. Below is additional information: 1. Pull over promptly: The correct approach for a regular tire blowout is to pull over immediately, replace the spare tire, and then drive to a repair shop or 4S store. For vehicles equipped with run-flat tires, they offer greater safety, as run-flat tires can still be driven at speeds not exceeding 80 km/h for about 80 km after a blowout. 2. Reason: This is because the sidewalls of run-flat tires are thicker, allowing them to support the vehicle and continue driving after a blowout, unlike regular tires, which may suddenly lose pressure, causing the rim to come into direct contact with hard surfaces like the ground. However, note that although run-flat tires have minimal impact on driving after a blowout, you should still drive to the nearest repair shop or 4S store for inspection. Driving too far may still damage the rim.

What Causes Excessive Body Vibration?

Your vehicle may be experiencing the following conditions: 1. Severe engine carbon buildup: The most common cause of car vibration is a dirty throttle body or excessive carbon deposits in the fuel injectors. When there's too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector gets largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This makes the vehicle difficult to start—only when the carbon deposits become saturated with gasoline does the engine start more easily. After starting, the gasoline adsorbed on the carbon deposits gets drawn into the combustion chamber by the engine's vacuum, making the mixture too rich. This fluctuation between lean and rich mixtures causes idle vibration after cold starts. The lower the temperature, the more fuel is needed for cold starts, and carbon deposits significantly affect whether cold starts proceed smoothly. 2. Ignition system issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance in the ignition system or weak sparking from the spark plugs can also lead to such symptoms. 3. Unstable fuel pressure: If you've already cleaned the engine carbon deposits, throttle body, replaced gaskets and spark plugs, but still notice body vibration at idle, it's recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings/malfunctioning of the intake pressure sensor can both cause body vibration. 4. Aging engine components: Car vibration can also be related to worn engine mounts. Engine mounts act as the engine's shock absorption system, absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and cabin, causing noticeable shaking at idle.

How many points will be deducted for exceeding the speed limit by 50%?

Driving a motor vehicle at a speed exceeding 50% of the prescribed speed limit will result in an immediate deduction of 12 points. After deducting 12 points, you can re-educate yourself, but if your driver's license is revoked, you cannot re-educate yourself and can only wait for two years before retaking the exam to obtain a driver's license. If it is due to an emergency, such as rescuing a patient, you can bring proof to the traffic bureau to cancel this deduction. The following is extended information: 1. "Attachment 2 of the Ministry of Public Security Order No. 123": Driving medium-sized or above passenger or cargo vehicles, school buses, or dangerous goods transport vehicles on highways or urban expressways at a speed exceeding 20% of the prescribed limit, or on roads other than highways or urban expressways at a speed exceeding 50% of the prescribed limit, as well as driving other motor vehicles at a speed exceeding 50% of the prescribed limit, will result in a one-time deduction of 12 points. 2. Regulations: Those responsible for fatal traffic accidents with equal or greater responsibility, or with drunk driving records, are permanently prohibited from applying; those whose driver's licenses have been revoked or canceled are prohibited from applying for 10 years; those who have accumulated 12 points are prohibited from applying for a large passenger vehicle license for 5 years, and from applying for a tractor or medium-sized passenger vehicle license for 3 years.
