WARNING
●Remove any heavy loads, such as snow
and ice, from the trunk lid before
opening it. Failure to do so may cause
the trunk lid to suddenly shut again
after it is opened.
●When opening or closing the trunk lid,
thoroughly check to make sure the
surrounding area is safe.
●If anyone is in the vicinity, make sure
they are safe and let them know that
the trunk is about to open or close.
●Use caution when opening or closing
the trunk lid in windy weather as it may
move abruptly in strong wind.
●The trunk lid may suddenly shut if it is
not opened 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 unexpectedly
opening or closing by itself. Make sure
that the trunk lid is fully open and
secure before using the trunk.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
●When closing the trunk lid, make sure
to 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.
●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 suddenly shut
again after it is opened.
■Trunk easy closer
In the event that the trun k lid is left slightly
open, the trunk easy closer will automati-
cally close it to the fully closed position. It
takes several seconds before the trunk
easy closer begins to operate. Be careful
not to catch fingers or anything else in
the trunk lid, as this may cause bone frac-
tures or other serious injuries.
■Power trunk opener and closer (if
equipped)
Observe the following precautions when
operating the power trunk opener and
closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding
area to make sure there are no obsta-
cles or anything that could cause any
of your belongings to get caught.
●If anyone is in the vicinity, make sure
they are safe and let them know that
the trunk is about to open or close.
●If the trunk closer switch is pressed
while the trunk lid is opening during
automatic operation, the trunk lid
stops opening. Take extra care when
on an incline, as the trunk lid may open
or close suddenly.

lid has to be operated manually. Take
extra care in this situation, as the
stopped trunk lid ma y suddenly shut,
causing an accident.

function, or the trun k lid may suddenly

Trunk Lid if there is little space under
the rear bumper.
■Jam protection function
Observe the following precautions.
Failure to do so may cause serious injury.
●Never use any part of your body to
intentionally activate the jam protec-
tion function.
●The jam protection function may not
work if something gets caught just
before the trunk lid fully closes. Be
careful not to catch fingers or anything
else in the trunk lid.
●The jam protection function may not
work depending on the shape of the
object that is caught. Be careful not to
catch fingers or anything else.
