What does an exclamation mark in the vehicle mean?

[EmmettLee]

There are generally three types of exclamation mark warning lights on the car dashboard: First, a triangle with an exclamation mark in the middle, which is the general fault indicator light. This light has two functions: 1. It lights up to remind the driver to turn off the traction control system; 2. If this light stays on while the traction control system is activated, it indicates a problem with the TCS. Normally, when the TCS is active, this light will flash. If it stays on continuously, it indicates a TCS issue. Second, a circle with an exclamation mark inside brackets, which is the brake system warning light; it lights up under the following conditions: 1. Some vehicles light up for a few seconds after turning on the ignition and turn off after starting the engine; 2. It lights up when the handbrake is engaged and turns off when released; 3. It lights up while driving if the brake fluid level is too low; 4. It lights up if there is a fault in the brake system. Third, a horizontal line with an exclamation mark below brackets, which is the tire pressure monitoring warning light. This light turns on when the pressure in one of the vehicle's tires is too low.
