On my 2002 the horn does not sound when I lock the car all the lights just flash. I like when the horn chirps it lets me know my doors are locked. My 99 does chirp and I was wondering if there is something I can do to make the horn chirp when I lock the car with the remote on my 2002. I do not have the owners manual either. Also on my 1999 the headlights work fine and everything but they do not switch off at the switch where as on my 2002 if I flip the switch to the DRLs the headlights turn off leaving only the DRLS and tail lights on. The 99 when I do that does nothing, the headlights just stay on. It just sucks because if your at a drive in movie theatre and your cold if you turn the car on to get some heat the headlights are on blinding other people.
