I recently found out about the headlight aiming control dial to adjust the angle of the headlights (to compensate for varying loads in the car).

Here's a helpful video from Nissan:

Here are the suggested positions based on occupants and luggage load, taken from the UK Ariya owner's manual:

Switch position	Number of front seat occupants	Number of rear seat occupants	Weight of load in luggage compartment
0	1	No occupants	No load
1	2	0 or 3	No load
2	2	3	Full load
3	1	No occupants	Full load
