If a child is accidentally locked in the trunk, they could suff er from heat
exhaustion, suffocation or other injuries.
● Do not allow a child to open or close the trunk lid.

WARNING
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resu lting in seri-
ous injury.
● Remove any heavy loads, such as snow and ice, from the trunk li d before
opening it. Failure to do so may cause the trunk lid to suddenl y 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 t hem know that
the trunk is about to open or close.
● Use caution when opening or closing the trunk lid in windy weat her as it
may move abruptly in strong wind.
● Do not attach any accessories other than genuine Toyota parts t o the trunk
lid. Such additional weight on the trunk lid may cause the lid to suddenly
shut again after it is opened.
● 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.
