There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system malfunction. Below is a detailed analysis of these four situations: General Malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: 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. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: A horizontal line under a bracket with an exclamation mark in the middle 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 System Malfunction: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection 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. Additionally, a red exclamation mark inside a circled bracket indicates a warning related to the braking system, primarily due to braking system failure or low brake fluid level. Immediate inspection and repair of the braking system are required to prevent accidents.

How to Drive an Automatic Transmission Car During the Break-in Period?

Driving methods for automatic transmission cars during the break-in period: 1. The break-in mileage is generally 500 kilometers, with the speed maintained between 60 to 70 km/h, and the engine speed should not exceed 2200 rpm; 2. From 500 to 1000 kilometers is the mid-term of the break-in period, where the speed can be increased from 60-70 km/h to 90-100 km/h, with the engine speed kept below 2500 rpm; 3. From 1000 to 1500 kilometers is the mid-to-late stage of the break-in period, where the speed can be increased to below 120 km/h, but the engine speed should not exceed 3000 rpm; 4. During the break-in period, each time you insert the key, turn it to the second position and wait for 10 seconds before starting the engine. This allows sufficient time for the internal oil pressure and fuel injection volume to adjust, ensuring optimal engine coordination; 5. Avoid placing too many heavy items in the trunk of the new car to reduce the load—the lighter the car, the better.
