hi evryone

can any one tell me what is the yellow circle that has some dotted lines around it mean,becouse when ever i press brakes this thing lights up on the dash thanks.

another question is there an e500 coupe?[/align]

 

Most likely it means brake sensor touching the brake disk indicating it is time to check the brakes and brake pads.

Check brake disks as well and it would be a good time to flush brake fluid if it is time.
