What does the triangular exclamation mark on the Mazda 3 dashboard mean?

[AryaDella]

A triangular exclamation mark on the car dashboard indicates a malfunction in the vehicle's general performance, components, or functions. Common causes 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. An exclamation mark indicates an abnormality or failure in the corresponding system. There are many indicator lights with exclamation marks on the car dashboard, 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: Automatic Transmission Fault: A yellow gear with an exclamation mark inside indicates an automatic transmission fault warning light, meaning there is a fault in the transmission or the transmission lubricant level is 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, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormality: An exclamation mark below a horizontal line with parentheses represents the tire pressure monitoring warning light, which lights up 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 indicates a lighting fault warning light, signaling a malfunction in the vehicle'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. In addition, during daily vehicle use, the fault lights displayed on the dashboard are divided into two colors—yellow and red—for different levels of severity: Yellow indicates a fault in the corresponding system that is not very serious. 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 call for 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 completion. If a light does not turn on when the ignition is switched 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 elimination of safety hazards.
