Normal Siren Behaviour for USA SLK320
Searching the forums and even facebook has been frustrating as I still do not know how my 2001 black benz is supposed to function. I have had it less than a year but never heard the siren chirp or wail or anything. The corner amber lights flash three times when I fob lock the car. The so-called netherlands option seems to be a factor; are USA cars delivered "silent" and the NL thing must be turned on with star system computer at cost of $$$ by dealer? I have not tried to scare the car into alarm mode by reaching in to locked car to try the glove box or open a door from inside. I am afraid it will start screaming and not shut up! What have other USA owners done to learn about this and what are the options? I have not opened the cowl cover to see if the siren is there or disconnected maybe by previous people. Thank you for help.

I own a 2001 slk230, I know my siren works because I set it off one time when my driver door lock didn't lock when the central locking system air line inside the door didn't lock the car.
I opened the door thinking I must have not locked the car that set the siren off, the other door and the trunk lid were locked but the drivers door did not lock.
I believe I pushed the lock and unlock buttons, or put the key in the door lock and twisted it, but I may have started the car, sorry I don't remember exactly what I did to shut it off.
I can tell you the siren is very LOUD, as a matter of fact its a high pitched ear piercingly loud noise you don't want to hear close up.

Yes as far as I know my car was born in or for the USA market,
no I do not know anyone that had the computer changed
My car does not chirp when I lock or unlock the doors.
I think what you need is a owners manual, or a service manual.
You would need both to match the country the car was built for.
Sorry I can't be more help.

I do have owner's book which I find oddly written and not clear, maybe it's a translation thing. I don't think it says anything about a chirp confirmation; that is why I am asking on the forum what is normal. If your siren screams with a bona fide violation but does not chirp with fob lock command, I would conclude that is the USA default setup. People that get their USA cars to chirp are taking an extra step I guess with dealer programming. You are the first and only person so far on three forums and facebook to clearly and pertinently reply which I do appreciate.
