Ducati Diavel 1260 Owner's Manual page 62

Once the "Hazard" function is activated, if vehicle is
turned off (key turned to "OFF"), the function stays
active for 2 hours. After 2 hours, the turn indicators
switch OFF automatically in order to save battery
charge.
Note
When turning the vehicle key ON with "Hazard"
function still active, the function remains active.
Note
If there is a sudden interruption in the battery
while the function is active, the instrument panel will
disable the function when the voltage is restored.
Note
The "Hazard" function has higher priority
compared to normal operation of the single turn
indicators, this means that, as long as it is active, it
will not be possible to activate the single right or left
turn indicators.
