The codes don't pop up automatically: you must retrieve them.
Were you aware of this?
The next time the screen lights up like that:
lay your thumb across the Mode, and Set buttons, and keep it there.
Then take another thumb, and push in the turnsignal switch. (Just like to cancel a signal)
That'll bring up any active codes.
if you see any: write them down!
Give this information to your dealer, and for even quicker service: report what you find in here!
