Before driving
Power back door
The power back door can be
opened using the power back door
opener switch, smart access system
with push-button start or wireless
remote control.
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■Before driving the vehicle
Before driving the vehicle, make sure
that the power back door is fully closed. If
the power back door is not fully closed, it
may open unexpectedly while driving,
causing an accident.
■Caution while driving
●Keep the power back door closed
while driving.
If the power 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 power
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 lug-
gage compartment, they could have heat
exhaustion or other injuries.
●Do not allow a child to open or close
the power back door.
Doing so may cause the power back
door to move unexpectedly, or cause the
child’s hands, arms, head, or neck to be
caught by the closing power back door.
■Operating the power 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 power back door
before opening it. Failure to do so may
cause the power back door to sud-
denly shut again after it is opened.
●When opening or closing the power
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 power back door is about to open
or close.
●Use caution when opening or closing
the power back door in windy weather
as it may move abruptly in strong wind.
●The power back door may suddenly
shut if it is not open ed fully. It is more
difficult to open or close the back door
on an incline than on a level surface, so
beware of the back door unexpectedly
opening or closing by itself. Make sure
that the back door is fully open and
secure before using the luggage com-
partment.
