2012 Acura MDX Owner's Manual - Page 411

AcuraLink® (U.S. models only) Unread messages have a closed envelope icon next to them. The icon disappears when it has already been read. NOTE: Only Diagnostic Info messages overlay the navigation screen while driving. They indicate if your vehicle has a problem that may need immediate attention (see page 413). Select ''Messages'', then select a message category by pressing ENTER. Select the message you want to read and press ENTER. After purchasing your vehicle, messages may not appear immediately. Your dealer has to register the vehicle identification before you can receive messages. This can take several days to process. Message Options When you open a message, you can read a summary of it, and then choose one of several options. If an option is not available for a message, that button will not be highlighted. 404
