When the S-AWC system oil is too hot
WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
Either of "AWC ECO", "NORMAL", "SNOW", "LOCK" should flash at the left upper, and "4WD SYSTEM OVERHEATING SLOW DOWN" should be displayed at the center. Then the drive mode selector will be disabled to avoid damage to the drive train components.
