What Causes the Exclamation Mark Light to Illuminate in a Car?

[SanAurora]

The reasons for the exclamation mark light illuminating in a car: 1. A red triangle with an exclamation mark in the middle is called a general fault light, which illuminates when the vehicle experiences a fault. Common issues include clutch overheating and fuel supply system malfunctions; 2. A red circular exclamation mark within brackets is the brake system warning light, which turns on when the handbrake is engaged; 3. A yellow exclamation mark with a line underneath within brackets is the tire pressure monitoring warning light, which illuminates only when the pressure in the vehicle's four tires is unbalanced or too low; 4. A yellow bulb with an exclamation mark inside is the lighting fault indicator light, indicating a fault in the car's light bulbs when it lights up; 5. A red steering wheel with an exclamation mark next to it is the steering system fault indicator light, which signals issues like power steering system failure, non-operation, or steering wheel lock when illuminated.
