    On my (much older) SL the frost can lower the main battery voltage and fool the alarm into going off. I keep a battery conditioner in the boot and connect it when the weather turns cold, like now.

    Developer was "bumping" the thread to the top so you get a response.

    Internet slang, basically.

    Although not a Merc my son has a Z3 and the alarm always goes off if its near freezing. I've tried all sorts to stop it but no luck. He now locks it with the key and leaves the alarm off if frost is predicted!
