What Does the Exclamation Mark on a Mercedes Dashboard Mean?

[LawsonLee]

An exclamation mark appearing on the car 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 wiper fault indicator. Below is a detailed introduction to the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor faults, fuel cut-off system intervention or malfunction, external light faults, and engine oil pressure sensor faults. 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 fault in the transmission or transmission lubricant 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 the car'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 lights to identify the issue. Wiper Fault: A yellow sector with an exclamation mark inside. This is the wiper fault indicator, indicating insufficient windshield washer fluid, a damaged washer fluid sensor, or a damaged wiper motor. The wiper is a blade structure installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Its main function is to clear rain, snow, and dust that obstruct visibility on the windshield. The wiper should be replaced if: it has been used for a long time and the rubber blade is aging; cracks appear on the rubber blade; there is a screeching sound when wiping the glass; marks are left on the wiped area; or the wiper shakes or jumps during use. In addition, during daily vehicle use, the fault lights displayed on the dashboard are divided into two 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. If the steering system warning light remains on, it indicates a problem with the power steering system. If the yellow indicator light is on, the steering system is partially malfunctioning, requiring greater force to turn the steering wheel. If the red indicator light is on, the steering system has completely failed. Note that 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 turn on when the ignition is switched on, remains on, or lights up while driving, it indicates a fault in the corresponding system. In such cases, seek professional assistance promptly to inspect the car and eliminate safety hazards.
