What does the exclamation mark next to the circle on the dashboard mean?

The exclamation mark next to the circle on the dashboard may be the brake system warning light. Possible reasons for it being illuminated include: 1. ABS function failure; 2. Severely worn brake pads that have become ineffective; 3. Brake fluid not meeting requirements. Abnormalities in the brake system may manifest as poor or failed braking, unilateral braking deviation, braking noise, brake drum overheating caused by brake drag, or parking brake failure. If the brake pedal gradually rises and feels spongy when pressed repeatedly, but remains low after a brief pause, this indicates air in the brake system, requiring brake system bleeding. If a single brake application is ineffective but braking improves with multiple pedal presses, this suggests excessive brake pedal free play or excessive brake clearance. Adjust the pedal free travel and inspect brake clearance, performing brake disassembly and repair if necessary.
Having worked at a 4S dealership for years, I frequently encounter this question from car owners. The circle with an exclamation mark on the dashboard is the brake system warning light. When illuminated, it typically indicates an issue with the braking system, such as low brake fluid level, incomplete release of the parking brake, or a malfunction in the ABS anti-lock braking system. If it suddenly lights up while driving, never ignore it – brake failure poses serious dangers. My recommendation is to immediately find a safe place to pull over, open the hood, and check the brake fluid reservoir level. If it's below the standard, promptly top it up with fresh fluid, but avoid using random low-quality brake fluid brands. If the fluid level is normal, the parking brake might not be fully released – try pressing the brake pedal a few times. If the light remains on, visit a repair shop to scan for specific trouble codes with diagnostic equipment. Neglecting this warning significantly increases the risk of brake failure during highway driving. Develop a habit of checking the fluid level every time you refuel to prevent unexpected issues. Safety comes first – addressing minor problems promptly prevents major hazards. Taking time for inspections is far better than breaking down mid-journey. Don't consider it a hassle; older vehicles require extra attention.
