Ducati Multistrada 2200S Pikes Peak Owner's Manual page 83

When the detected temperature drops to 39°F (4°C),
the display warns that the formation of ice is possible.
The indication turns off when the temperature rises
to 43°F (6°C).
Attention
This warning does not exclude the possibility of
icy road sections even at temperatures above 39°F
(4°C); when external temperatures are "low" it is
always recommended to ride carefully, particularly on
sections that are not exposed to the sun and/or on
bridges.
