w124 coupe warning lable

Hi to all on my 1994 E220 coupe as a member of the merc club last year i entered it in the concours ,but lost marks because inside boot where the locking catch is on the black there is a warning lable RED in colour and that is the one i kneed but have trouble locating it even at the main dealer can someone please open there boot look down and see if there is a part number which i could have .
Many thanks
