i have a dumb question. supposedly the 2018 nx`s are all led headlight equipped vehicles. so how do i know if i have auto leveling or not?

 

Start engine, put gear selector in "D", point car at wall, turn on headlights, note light cutoff position on wall, engage handbrake (pull UP on the handbrake switch) and release the brake pedal.
This should drop your rear end a few mm, simulating a heavy load in the rear. Check to see if the position of the cutoff on the wall rises (when you release the brake pedal) and lowers (auto levelling at work)
After that, you could try putting it into "R" and repeating the steps above. This should raise your rear end, simulating the load being removed. You should see a reverse in behaviour of the headlights.

Anyway, I think all the NXs have auto levelling.
