WARNING
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
■Before driving
●Make sure that the trunk lid is
fully closed. If the trunk lid is not
fully closed, it may open unex-
pectedly while driving and hit
near-by objects or luggage in
the trunk may be thrown out,
causing an accident.
●Do not allow child ren to play in
the trunk.
If a child is accidentally locked
in the trunk, they could suffer
from heat exhaustion, suffoca-
tion or other injuries.
●Do not allow a child to open or
close the trunk lid.
Doing so may cause the trunk
lid to open unexpectedly, or
cause the child’s hands, head,
or neck to be caught by the
closing trunk lid.
■Important points while driving

In the event of sudden braking or
a collision, they are susceptible to
death or serious injury.

tions.
Failure to do so may cause parts
of the body to be caught, resulting

●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
