2005 Acura RL displayed due for service A1
 

What does this require to be done?

Also in the top right hand corner of my gps screen is an icon of an envelope displayed. when check the message center tells me that my all wheel drive is not engauging, it tells me how to reset it but after awhile(someting later in the same day) the message center will display the envelope icon again on my gps screen for the same issue.

Waht is the fix for this?

:rtfm: Your owner's manual is oh so helpful when you car is trying to tell you something.
