Ah, Canadian models for the auto-leveling headlight. I had them on a Lexus RX350 and didn't care for them. They were set too low. At night on low beam I didn't feel safe driving on a dark road above 35mph. The dealer said they were set at factory specs and they would night adjust them higher.
With the Lexus I could see them set themselves immedaitely upon starting the engine, by watching the beams against the garage wall. During routine driving, never saw them "moving". I believe the purpose of them is to compensate for a heavy load or passengers in the back.
