WARNING
Observe the following precautions.
Failure to do so may cause parts of the
body to be caught, resulting in death or
serious injury.
■Before driving the vehicle
Before driving the vehicle, make sure
that the back door is fully closed. If the
back door is not fully closed, it may open
unexpectedly while driving, causing an
accident.
■Caution while driving
●Keep the back door closed while driv-
ing.
If the back door is left open, it may hit
nearby objects while driving or lug-
gage may be unexpectedly thrown out,
causing an accident.
In addition, exhaust gases may enter
the vehicle, causing death or a serious
health hazard. Make sure to close the
back door before driving.
●Never let anyone sit in the luggage
compartment. In the event of sudden
braking, sudden swerving or a colli-
sion, they are susceptible to death or
serious injury.
■When children are in the vehicle
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●Do not allow children to play in the lug-
gage compartment.
If a child is accidentally locked in the
luggage compartment, they could
have heat exhaustion or other injuries.
●Do not allow a child to open or close
the back door.
Doing so may cause the back door to
move unexpectedly, or cause the
child’s hands, arms, head, or neck to be
caught by the closing back door.
■Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the
body to be caught, resulting in death or
serious injury.
●Remove any heavy loads, such as snow
and ice, from the back door before
opening it. Failure to do so may cause
the back door to suddenly shut again
after it is opened.
●When opening or closing the back
door, 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 back door is about to open or
close.
●Use caution when opening or closing
the back door in windy weather as it
may move abruptly in strong wind.
●Vehicles without power back door:
The back door may suddenly shut if it is
not opened fully. It is more difficult to
open or close the back door on an

that the back door is fully open and
secure before using the luggage com-
partment.
