What does the yellow exclamation mark in a Mercedes-Benz C200 indicate?

[Jerry]

The appearance of an exclamation mark on the car's dashboard indicates an abnormality or malfunction in the corresponding system. There are many dashboard indicator lights with exclamation marks, such as the tire pressure indicator, lighting 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 general performance or component malfunction in the car. 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 is the automatic transmission fault warning light, indicating a transmission fault or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses represents a brake system warning, indicating either a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Anomaly: An exclamation mark with a horizontal line below parentheses represents the tire pressure monitoring warning light, which 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 check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. Additionally, during daily vehicle use, the dashboard warning lights are divided into two colors—yellow and red—to indicate different levels of severity: Yellow indicates a fault in the corresponding system, but the issue is not very severe. Reduce speed and proceed to a repair shop to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In such cases, do not continue driving. Pull over immediately and seek professional assistance to prevent unpredictable risks to the vehicle and personal safety. Note: When the car is started, all lights will illuminate for an automatic system check and will turn off after the check is completed. 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 cases, seek professional help promptly for inspection and troubleshooting to eliminate safety hazards.
