On my Clio 2 (2003 - 53 Reg): With engine off, turn ignition key to the first position. On lighting stalk, turn knob from O to Sidelights position, then repeat again to Reactivate auto (2 beeps heard). To Deactivate auto, turn the knob from O to Sidelights, just the once (1 beep heard). This procedure is also in the manual. Hope this helps.
