What Causes the Yellow Light on the Dashboard to Illuminate?

[TylerLynn]

The yellow exclamation mark on the dashboard is an alarm signal from the tire pressure monitoring device, indicating that the tire pressure is too low, possibly due to a leak or prolonged lack of inflation. There are generally three types of exclamation warning lights on the car dashboard: 1. A triangle with an exclamation mark in the middle, which is a general fault indicator light. This light is the TCS (Traction Control System) indicator. When this light comes on, it reminds the driver to turn off the traction control system. If the light stays on while the traction control system is active, it indicates a problem with the TCS. 2. A circle with an exclamation mark inside, which is the brake system warning light. It indicates that the parking brake (handbrake) is engaged or there is a fault in the brake system. 3. A horizontal line with an exclamation mark below, which is the tire pressure monitoring warning light. This light illuminates when the pressure in one of the vehicle's tires is too low.
