The Pitot heating caution message is displayed when the Pitot
heating is switched OFF, or when there is a failure of the Pitot

the ground can also cause the Pitot heating caution message
to be displayed. In this case it indicates the activation of the
thermal switch, which prevents overheating of the Pitot

the system. After a cooling period, the heating system will be
switched on again automatically.
