CAUTION
nUsing the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in seri-
ous injury.
lRemove 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 fall closed again
after it is opened.
l When opening or closing the trunk lid, thoroughly check to make sure the
surrounding area is safe.
l If anyone is in the vicinity, make sure they are safe and let them know that
the trunk is about to open or close.
l Use caution when opening or closing the trunk lid in windy weather as it
may move abruptly in strong wind.
l Do not attach any accessories other than genuine Toyota parts to the trunk
lid. Such additional weight on the trunk lid may cause the lid to fall closed
again after it is opened.
lThe trunk lid may fall 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.
l When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
l 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.
