Red exclamation mark (specifically a bracket circle with an exclamation mark in the middle) represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the brake system is required to avoid accidents. Apart from the red exclamation mark indicating brake system failure, all other exclamation marks on a 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/function malfunction in the car. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, 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. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: A bracket with a horizontal line below and an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb exclamation mark. This is the lighting fault indicator light, signaling a malfunction in the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible. Alternatively, you can perform a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights, to identify the issue.

What Causes Fogging on the Outside of Car Windows?

Reason: Fogging on the car windshield occurs due to a significant temperature difference between the inside and outside of the vehicle. The carbon dioxide exhaled by passengers contains a lot of water vapor, which condenses into tiny water droplets when it comes into contact with the cold glass. Here are some additional details: 1. Utilize air convection: Due to seasonal temperature variations, the difference between the inside and outside of the car increases. Warm, humid air inside the car meets the cold windshield, releasing heat and condensing, which easily causes fogging. Therefore, you can slightly open a window to allow air convection between the inside and outside of the car, balancing the temperature difference and preventing fogging. 2. Use the air conditioner's warm air: Turn on the warm air setting and direct it toward the windshield to quickly raise the glass's temperature. This eliminates the conditions for warm, humid air inside the car to release heat and condense on the window, thereby preventing fogging.

What are the reasons for the idle engine vibration in Changan Raeton CC?

The following are the reasons for the idle engine vibration in Changan Raeton CC:1. Sensor failure: It may be due to signal confusion from sensors such as the air flow sensor or fuel consumption sensor in the engine, leading to deviations in the computer's reception and causing the engine to vibrate at idle.2. Insufficient oil supply: It might be because the engine oil did not keep up in time during operation, preventing the engine from obtaining optimal mechanical operating conditions, resulting in engine vibration.3. Computer board issue: There could be inherent problems with the vehicle's computer board, which is also a reason for the engine's idle vibration. The onboard computer receives incorrect signals from the engine or sends out chaotic signals, leading to engine issues.

Can you change lanes when there is a dashed line in the middle of a solid yellow line?

If there is a solid line in the middle and dashed lines on both sides, you can change lanes. 1. According to the "Motor Vehicle Management Regulations," white lines are used to distinguish different lanes in the same direction: 1. Dashed lines allow lane merging and changing. 2. Solid lines prohibit lane merging and arbitrary lane changes. 2. Regarding yellow lines: 1. They are used to separate lanes in opposite directions, typically painted in the middle of the road, acting as a divider between two directions. 2. Whether it's a single or double yellow line, as long as it's solid, crossing is strictly prohibited, such as for overtaking, turning, or U-turns. 3. Whether it's a single or double yellow line, if it's dashed, you can overtake or make a U-turn safely. 4. Single yellow lines are generally used on roads with up to four lanes (including bicycle lanes), while double yellow lines are used on wider roads. 5.
