    umm...don't start it up..????

    seriously, must be a safety item.

    to inform you, if you are away from the vehicle, that it is about to start, unattended..???

    look at the relay panel, fuse panel for anything relating to this, like "start up/autostart warning system..??

    if so, try pulling that fuse/relay, and tell us what happens?
