- An AWD system oil overheat
- Worn out or overheated clutch plates
- Various electrical issues

If this message appears, stop as soon as possible and turn off the ignition for 30 seconds. Restart the vehicle and check for the message on the DIC display. If the message still displays or appears again when you begin driving, the system needs service. See your dealer right away.
