"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) 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 instrument panel will
disable the function when the voltage is restored.
