The trunk can be opened using the
trunk opener switch, entry function
or wireless remote control.
If the vehicle is equipped with a
power trunk lid, the trunk can be
closed using the trunk closer.
WARNING
Observe the following precautions.
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 unexpectedly
while driving and hit near-by objects or
luggage in the trun k may be thrown
out, causing an accident.
●Do not allow children to play in the
trunk.
If a child is accidentally locked in the
trunk, they could suffer from heat
exhaustion, suffocation or other inju-
ries.
●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
Never let anyone sit in the trunk. In the
event of sudden braking or a collision,
they are susceptible to death or serious
injury.
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the
body to be caught, resulting in serious
injury.
●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

the trunk lid in windy weather as it may
move abruptly in strong wind.
●Vehicles without power trunk lid: The
trunk lid may suddenly shut if it is not
