All (please excuse a newbie question)...

How can I switch the FSS display from days to miles? The quick reference guide says "You can push the **** to choose between a display that shows you miles to next service or days to next service".

Well, I've been pressing, holding, etc with no success. And yes, I've tried it with no key and with the key in the ON position too. I can easily get the days display but can't switch it to miles.

Again, a newbie question but couldn't find this on the forum nor on the internet. Even tried looking up Mercedes sites and forums for it...

Thanks in advance!
