What does the yellow half-circle exclamation mark light on the car mean?

[MatthewLynn]

Dashboard indicator light with a yellow half-circle exclamation mark typically indicates low tire pressure. Door status indicator light: This light shows whether the doors are fully closed. It illuminates when a door is open or not properly closed, alerting the driver that a door is ajar, and turns off when the door is closed. Parking brake indicator light: This light turns on when the parking brake handle (i.e., handbrake) is engaged. It automatically turns off when the handbrake is released. In some car models, this light may also illuminate when the brake fluid level is low. Battery indicator light: This light displays the working status of the battery. It lights up when the ignition is turned on and turns off after the engine starts. If it does not light up or remains lit continuously, the generator and circuit should be checked immediately.
