Coffee cup icon in the instrument cluster
I just got my 2010 E550 coupe about a week ago. I notice there is coffee cup icon appearing in the instrument cluster all the time. Is it normal? I called my salesman and he told me it's normal. However, when I read the manual and the manual says the coffee cup icon appears when Attention Assist is mulfunctioning and I need to contact the dealer asap. Does anyone know if it's normal? Thank you so much.
