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.

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.

■Note for the entry function
●Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win-
dow or outside door handle, near the

hybrid system is star ted or power switch
modes are changed.
●Do not leave the electronic key on top of
the instrument panel or near the door
pockets when exiting the vehicle.
Depending on the radio wave reception
conditions, it may be detected by the
antenna outside the cabin and the door
will become lockable from the outside,
possibly trapping the electronic key
inside the vehicle.

such as in the rain or in a car wash when
the electronic key is
within the effective
range. (The door will automatically be
locked after approximately 60 seconds if
the doors are not opened and closed.)
●If the wireless remote control is used to
lock the doors when the electronic key is
near the vehicle, there is a possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock sensor while
wearing gloves may delay or prevent lock
operation. Remove the gloves and touch

repeatedly. In that case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle.
(Take care to ensure that the key is not
stolen.)

the multi-information display and a
buzzer will sound outside the vehicle. To
turn off the alarm, lock all the doors.
●The lock sensor may not work properly if
it comes into contact with ice, snow, mud,
etc. Clean the lock sensor and attempt to
operate it again.
