rounding area is safe.

trunk is about to open or close.

●Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on the trunk lid may cause the lid to fall closed again after

fully. It is more difficult to open or close
the trunk lid on an incline than on a level
surface, so beware of the trunk lid unex-
pectedly opening or closing by itself.

and secure before using the trunk.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.

press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.
