I wanted to post this to let those of us and future members know the 2011 basic screen does not inform you about your coolant maintenance.
If you reach the 15,000 miles but a dealer informs you to wait for the message, you could drive 100,000 miles and never see such a message.

I noticed there was no reset option under the basic screen so a search in the manual only made reference to this message with the optional message center (the 4.2 inch LCD screen in the dash).
(2011 Diesel Supplement, 5th printing; pg. 50)

Just an FYI for those of you who may be depending on the computer modules to inform you of scheduled maintenance tasks.

 

My DIC did indeed finally come on and indicate to check coolant.

 

The basic two line, one font color info center?
Because the wording says optional message center will report this.

 

I have the full blown DIC LCD screen - with the color display - so maybe I have a feature that you don't sorry....

 

Whats considered "the basic screen"?

 

Similar to the 2008-2010 models info center.
This is an example but you can ignore the low oil message.
(It does that prior to start sometimes; "working as designed" so I hear)
