A yellow 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, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and wiper fault indicator. Below is a detailed introduction to the exclamation mark fault lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor faults, fuel cutoff system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary 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. This is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. The transmission oil should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle. This represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormality: A horizontal line with parentheses and an exclamation mark below. This represents the tire pressure monitoring warning light, which lights up when the car's 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. This is the lighting fault indicator, indicating a fault in one of the car lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem. In addition, during daily use of the vehicle, the fault lights displayed on the dashboard are divided into two different colors: yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest repair point for maintenance to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In this case, do not continue driving. Pull over immediately and seek professional assistance to prevent unpredictable risks to the vehicle and personal safety. It is important to note that when the car is started, all lights will turn on for a system self-check and will automatically turn off after the check is completed. If a light does not turn on when the ignition is switched on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection and repair to eliminate safety hazards.

That day when I was driving out, suddenly a yellow exclamation mark popped up on the dashboard, and my heart skipped a beat. I asked a few experienced driver friends, and they all said the most common issue is low tire pressure, possibly due to a slow leak or temperature changes. But it could also be a brake system problem, such as excessively worn brake pads or an electronic malfunction. If ignored, it could be dangerous at high speeds. It's recommended not to continue driving; instead, find a nearby repair shop to check the tire pressure or the overall system—safety first. I usually make it a habit to measure the tire pressure myself every month to avoid these minor troubles affecting my driving mood.

Can the first maintenance be done after 1000 kilometers for a new car?

Generally, the first maintenance for a new car is scheduled at either six months or 5,000 kilometers, whichever comes first. There is also a new car inspection, which usually requires returning to the dealership after a few hundred or 1,000 kilometers. The first maintenance does not need to be done at 1,000 kilometers. Components of car insurance: Car insurance generally includes two parts: basic insurance and additional insurance. Basic insurance is further divided into vehicle damage insurance and third-party liability insurance. Coverage of car insurance: Vehicle damage insurance covers the loss of your own vehicle; third-party liability insurance covers damages to targets outside your own vehicle, such as people and public property you hit, the other party's car, etc.; passenger liability insurance covers personal and property losses of passengers in your own vehicle; theft insurance covers the loss when your own vehicle is stolen; no-deductible coverage ensures 100% compensation in case of an accident. If no-deductible coverage is not purchased, you will bear 30% of the deductible for each accident.

What is the normal intake air temperature for a car?

Car intake air temperature normally ranges from 10 to 50 degrees Celsius. The intake air temperature sensor is a negative temperature coefficient thermistor. When the temperature rises, the resistance decreases, and when the temperature drops, the resistance increases. The change in resistance in the circuit leads to voltage variations, thereby generating different voltage signals to complete the automatic operation of the control system. When the engine is cold, the signal from the intake air temperature sensor is basically the same as that from the engine coolant temperature sensor. When the engine is warm, its signal voltage is approximately 2 to 3 times that of the coolant temperature sensor. Thermocouples are commonly used temperature sensors in temperature measurement, characterized by a wide temperature range, adaptability to various atmospheric environments, durability, and no need for power supply.

How to Deal with New Car Wiper Blades Not Cleaning Properly?

Methods to address new car wiper blades not cleaning properly: 1. Adjust the wiper blade angle using a debugging wrench to hold the wiper; 2. Gently roll and adjust it to a straight position; 3. If the rubber strip of the wiper blade has aged and hardened, causing poor contact with the glass, it may result in ineffective cleaning. In this case, the wiper blade can be replaced. Wiper blades are designed to clear rainwater. Avoid using them to clean dust or stains on the windshield under normal circumstances. The primary function of wiper blades is to remove rainwater. Unknown stains on the glass may cause the rubber strip's edge to age or wear, shortening the wiper blade's lifespan.

What Are the Maintenance Contents for New Energy Vehicles?

"The Structure and Maintenance of New Energy Vehicles" includes a total of 5 projects and 16 tasks. The main contents cover an overview of new energy vehicles, safe usage of new energy vehicles, the basic structure and maintenance of pure electric vehicles, the structure and repair of the Prius hybrid electric vehicle, and fuel cell vehicles, among others. The following are the differences between the maintenance methods of new energy vehicles and traditional vehicles: From the perspective of vehicle structure: The structure of new energy vehicles differs from that of traditional vehicles. The parts for new energy electric vehicles are harder to come by and are certainly more expensive. The core components of new energy vehicles mainly revolve around the three electric systems (battery, motor, and electronic control), and repairing these systems requires diagnostic instruments and other methods, relying on modern equipment in concept. Additionally, appropriate protective measures must be taken during vehicle maintenance, including personal protection such as protective clothing and insulated gloves. From the perspective of vehicle parts and other aspects: Traditional vehicle maintenance is more straightforward, as traditional vehicles are mostly composed of mechanical parts, making repairs simpler and requiring fewer tools to fix a car. From the perspective of vehicle maintenance locations: Much of the information regarding new energy vehicle maintenance is still in the confidential stage, coupled with extended warranty periods, meaning repairs can only be performed at 4S stores or designated dealerships. In contrast, due to years of development, traditional vehicle maintenance is no longer limited to specific locations, with a larger pool of maintenance personnel available.

What Causes Fogging in Headlights?

Headlight fogging occurs due to temperature differences. If severe water droplets form, it indicates poor sealing, which is a quality issue. Headlights have an intake pipe and an exhaust pipe to vent heated air from the lamp. After turning off the engine, especially at night, the headlight interior cools down, causing water vapor in the air to condense on the lamp. This moisture evaporates when exposed to sunlight or after the headlights are turned on for some time, exiting through the exhaust vent. Headlights, also known as headlamps, are crucial components for safe vehicle operation. Mounted on both sides of the front of the car, they illuminate the road during nighttime driving and come in two or four configurations. The farther the headlight beam reaches and the better its light distribution characteristics, the higher the vehicle's safety performance.
