What does a yellow circle with an exclamation mark on the dashboard mean?

Dashboard showing a yellow circle with an exclamation mark indicates the starter system malfunction indicator light. Possible causes for its illumination include: 1. Battery depletion or weak charge; 2. Loose or disconnected starter wiring; 3. Worn brushes or misaligned brush surfaces with weak springs; 4. Short circuits or open circuits in field coils or armature windings. The starting system converts electrical energy stored in the battery into mechanical energy. Its function involves generating power through a DC motor, which then drives the engine crankshaft via mechanical linkage to initiate engine startup. This system consists of the battery, wiring, ignition switch, starter motor, relay or solenoid switch, and starter engagement mechanism.
I've been driving for many years, and the most common issue indicated by that yellow circle with an exclamation mark on the dashboard is usually a problem with the braking system. For example, the handbrake might not be fully released, or there could be insufficient brake fluid. When starting the car, if the light is on, my first reaction is to check if the handbrake is pulled too tight. After releasing it, I see if the light goes off. If it's still on, I pop the hood to check the brake fluid reservoir level—it should be between the MIN and MAX lines. If it's below the MIN line, it needs topping up or repairing. If the light remains after all these checks, it might be a faulty sensor or worn-out brake pads. In such cases, don't force driving—safety first—and head to a repair shop immediately for inspection. Neglecting the braking system can be very dangerous. Once, I ignored the light on the highway, and the brakes became soft, nearly causing an accident. Since then, I've been extra careful about this.
