page 64 of Owner's Manual: General information section.
The tail, city, and license plate lights are on whenever the ignition key is in the "ON" position. The Headlight only goes on after the starter button is released after starting the engine.
(City lights are the two additional led lamps in the Headlight housing)
I believe these all serve as parking lights if you were temporarily stopped but didn't want the motor running. However, since the key cannot be removed while in the on position this function would have limited use.
