What Does It Mean When an Exclamation Mark Lights Up on the Car Dashboard?

1 Answers

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. Many indicator lights on the car dashboard feature an exclamation mark, such as the tire pressure indicator light, lighting system fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and windshield wiper fault indicator. Below is a detailed explanation of the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is advisable to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is necessary to prevent accidents. Tire Pressure Anomaly: A horizontal line with parentheses and an exclamation mark below represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible or perform a self-check, focusing on commonly used bulbs like turn signals, fog lights, and interior lights to identify the issue. Additionally, during daily vehicle use, fault lights on the dashboard are displayed in two different colors—yellow and red—as warnings: Yellow indicates a fault in the corresponding system that is not extremely severe. Reduce speed and proceed to a repair facility to eliminate potential safety hazards. Red indicates a critical issue in the corresponding system. In such cases, do not continue driving. Pull over safely and seek professional assistance immediately to avoid unpredictable risks to the vehicle and personal safety. Note: When starting the car, all dashboard lights will illuminate for a system self-check and will turn off automatically after the check is complete. If a light does not illuminate when the ignition is turned on, remains lit, or lights up while driving, it indicates a fault in the related system. In such situations, seek professional help promptly for inspection and resolution of potential safety hazards.

Will the car battery be affected if the car is not used for two months?

Leaving a car unused for two months will affect the battery. The battery charges automatically while driving, but it will still discharge when the vehicle is idle. If the car is not used for an extended period, it is advisable to disconnect the battery cables or start the vehicle every two weeks and drive it for several dozen kilometers to ensure the battery remains functional. Here are some precautions for long-term car battery storage: 1. Timely charging: Check the battery every two weeks during idle periods, such as inspecting the electrolyte level. The battery's electrolyte level should be 10-15mm above the electrode plates; if it is insufficient, add distilled water promptly. Owners can ask friends or family to help maintain the vehicle by starting it for 5-10 minutes every one or two weeks to recharge the battery, while also checking for any other potential issues. 2. Power disconnection: If no one is available to help maintain the vehicle, the negative terminal of the battery can be disconnected to cut off power, preventing energy consumption. Just remember to reconnect the terminal when restarting the vehicle.

What is the difference between National 5 and National 6 vehicles?

The biggest difference between National 5 and National 6 vehicles lies in their exhaust emissions. The National 5 standard sets the carbon monoxide limit at 1000mg/km, while the National 6a standard reduces it to 700mg/km, and the National 6b standard cuts it in half to just 500mg/km. Limits for other pollutants such as nitrogen oxides and particulate matter have also been significantly reduced. Specific details are as follows: 1. The difference in catalytic converters: The National 6 emission standard reduces particulate matter by 67% and nitrogen oxides by 77% compared to National 5, which can be simply understood as "the difference of one catalytic converter." 2. National 6a and National 6b: The National 6 standard is known as the strictest emission standard to date, implemented in phases with two emission limit schemes—National 6a and National 6b—rolled out in 2020 and 2023, respectively. Additionally, key regions with special requirements for atmospheric environmental management can implement the National 6 emission limits ahead of schedule.

What Causes a Truck's Air Conditioning to Not Cool Properly?

Truck air conditioning may not feel cool enough due to several reasons: insufficient refrigerant; excessive refrigerant; clogged filter screens; air entering the air conditioning system; or inadequate heat dissipation from the condenser. Below are solutions for a truck's air conditioning not cooling properly: Cleaning the Radiator and Condenser: You can rinse the radiator and condenser at home using a garden hose. Avoid using a high-pressure water gun because the condenser is made of very thin aluminum material, which can easily deform under high pressure. If they are too dirty, it's recommended to go directly to a 4S shop for cleaning. Replacing the Air Conditioning Filter: It is advisable to replace the air conditioning filter once a year, but it should be checked every six months. Checking for Low Refrigerant Levels: If the refrigerant is low, simply top it up. Also, check for any refrigerant leaks.
