the low beam off: in this mode, the instrument panel
automatically switches from the DRL light to the low
beam and vice versa, according to the detected
ambient light conditions. The display shows the green
logo with letter A.
Warning
Using the DRL light in AUTO (automatic) mode
in case of poor light conditions, especially in case of
fog or clouds, could impair safety: in this case DUCATI
recommends to manually activate the low beam.
DRL in MANUAL mode
If the DRL light is in this mode, it does not change
status when starting the engine. To switch on or off
the DRL light it is necessary to press button (5). The
display shows the yellow logo with letter M.
Warning
Using the DRL light in poor light conditions
(dark) could compromise the riding visibility and
dazzle who is coming on the opposite lane.
Note
Using the DRL light during the day improves
visibility as it is easier to perceive by those coming on
the opposite side compared with the low beam.
