I have a 2004 S4 - I get a message with MPH in the center and a another message with and up/down arrow with the low beams icon. I do not have an owner's manual. Any body know what up with this????

 

there is a setting you can have that sets like a speed alarm. And for whatever speed you set it at..if you go over that speed the alarm goes off. you can turn it on and off with the control stick thingy. pretty sure that is what it is

 

that should be what it is, you can for some reason set the alarm to come on when you are going too slow or going too fast. can be fun,

 

You can never go too fast :P
