Engine starting with white smoke is caused by: 1. The engine temperature being too low; 2. Incomplete combustion of some fuel, resulting in white smoke being expelled with the exhaust; 3. Water in the fuel supply system, which can cause white smoke when starting. Daily car usage precautions include: 1. Regularly check and replenish antifreeze; 2. Avoid using the windshield wipers or spray nozzles when the windshield is frozen; 3. Regularly check the battery charge; 4. Adjust tire pressure; 5. Warm up the car for about 1 minute before driving; 6. Start and drive slowly on icy roads.

What does the yellow triangle with an exclamation mark inside the car mean?

A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance or components and functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, and engine oil pressure sensor failure. Solution: It is necessary to visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in cars. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark indicators: a yellow gear with an exclamation mark inside, a red circle with an exclamation mark in the middle, a yellow bracket with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic transmission fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant below the normal range. The transmission oil should be replaced promptly. Brake system fault: A circle with an exclamation mark in the middle represents a brake system warning, mainly indicating brake system failure or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Tire pressure abnormality: A bracket with a horizontal line and an exclamation mark in the middle represents the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark is the lighting fault indicator, indicating a malfunction in the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
