We bought an 08 H3 Alpha. The headlights on warning sound nor the remote door lock horn honk don’t work, any suggestions?

 

 

Take a read through the Owner's Manual?

I have never turned on the headlights in either H3 I owned, it does it itself when dark, and turns them off by itself.

MOVED this as ALL H3 Questions go in the H3 Section.

 

There is no "headlights on" warning sound that I am aware of (I, too, have an '08 Alpha); they are automatic (even if you manually turn them on, they turn back off/to auto when you turn the vehicle off).. The remote feedback settings can be changed following the directions on page 3-42 of the owner's manual.
