"Parking" function
This function activates the "PARKING" mode.
The "PARKING" function activates the front and rear parking
lights when the vehicle is turned off so it is visible when
parked.
The function is activated by pressing the button (2, fig. 14)
"▼" for 3 seconds during the first 60 seconds after the
motorcycle was turned off.
Once the function is activated, the indication will remain on
the circular display for 5 seconds and the lights will remain on
for 2 hours. After 2 hours, then will turn off automatically.
To interrupt the function, turn the vehicle on and off (Key-On
/ Key-Off).
Note
If there is a sudden interruption in the battery while the
function is active, the dashboard will disable the function
when the voltage is restored.
Warning
The frequent use of this function can considerably
reduce the battery charge; Ducati recommends using this
function only when necessary.
