Prius Yellow Triangle Warning Light. That yellow triangle is the only thing that might tell you your oil is low. Then the dash lights starting flickering and the YELLOW triangle came on and I got the message to apply the parking brake on flat ground.
The battery is dead an when trying to charge a temp warning shows up with a yellow flashing triangle.
If the yellow light is a triangle with an exclamation point in it, it means you traction control is either working at that instant, or shut off.
