call me a putz!
 

ok i've looked in threads here and can't find out what i need, now the whole world will know what a putz i am! on the dash warning lights of my 87 190e 2.6L between the battery and brake warning light is a circle w/ 6 dash marks around it. is this the O2 sensor warning light? (still looking for a owners manual so i can familiarize myself with some of this "easy stuff")

dohh!
 

now as i hit the enter button and submit the last request i see O2 sensor on extreme right side. what is the circle?

Brake pad warning light.

thanks!!

Only those who don't search first deserve to be called a putz. All other questions welcome.
