According to my handbook the bottom left corner light is the airbag light, the top left corner symbol is the seat belt warning light. I've got the airbag light come up on my car and my airbag light next to the rear de-mister button is on as well so i've got a fault with mine which i need to get checked out as the airbags aren't opperating correctly, would recommend getting it checked it out if it is the airbag light.
