when the temperature light is green means that the engine is cold and needs to be warmed up.
If it's red it's overheating, blue it's not hot enough.

What you see is NOT a flag it is a thermometer over water. This is the engine temperature light. If it is on the engine is overheating.
Tire pressure
Read the owners manual.
Low fuel you idiot
On my 95 Avalon, there was a yellow picture of a car showing that my rear lights (license plate) were out.
its a rear bulb failure indicator if it comes on when brake is first depressed it is a brake light bulb if it is on when you start the car it is a ride light or park light
the yellow light on your dash means thst you have a bulb out in the rear of your vehicle. Hava a nice day.
I have a 2000 sienna..........and had that light come on......in has to do with the braking system
Look in your owners manual. Or the quick guide that came with the yaris.
