HIGHLANDER_U (OM0E017U)
WARNING
■Power back door (if equipped)
Observe the following precautions when operating the power back door.
Failure to do so may cause death or serious injury.
● Check the safety of the surrounding area to make sure there are no obsta-
cles or anything that could cause any of your belongings to get caught.
● 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.
● If the power back door system is turned off with the main switch while the
back door is operating automatically, the automatic operation is stopped.
The back door then has to be operated manually. Take extra care when on
an incline, as the back door may open or close unexpectedly.
● If the operating conditions of the power back door are no longer met, a
buzzer may sound and the back door may stop opening or closing. The
back door then has to be operated manually. Take extra care when on an
incline, as the back door may open or close abruptly.
● On an incline, the back door may suddenly shut after it opens. Make sure
the back door is fully open and secure.
● In the following situations, the power back door may detect an abnormality
and automatic operation may be stopped. In this case, the back door has
to be operated manually. Take extra care when on an incline, as the back
door may open or close abruptly.
• When the back door contacts an obstacle
• When the battery voltage suddenly drops, such as when the engine
switch is turned to the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system) or the
engine is started during automatic operation
● If a bicycle carrier or similar object is attached to the back door, the power
back door may not operate, causing itself to malfunction, or the back door
may move in the closing direction after being opened, causing someone’s
hands, head or neck to be caught and injured. When installing an acces-
sory part to the back door, ask your Toyota dealer for details.

WARNING
●Do not pull on the glass hatch damper stay to close the glass hatch, and
do not hang on the glass hatch damper stay.
Doing so may cause hands to be caught or the glass hatch damper stay to
break, causing an accident.
● Do not attach any accessories other than genuine Toyota parts to the
glass hatch. Such additional weight on the glass hatch may cause the
glass hatch to suddenly shut again after it is opened, resulting in death or
serious injury.
● Do not open the glass hatch while the rear wiper is switched on. (If the rear
wiper is switched on while the glass hatch is open, the wiper motor drive
disc will be rotating on the door panel.)
●The glass hatch may suddenly shut if it
is not opened fully. It is more difficult to
open or close the glass hatch on an
incline than on a level surface, so
beware of the glass hatch unexpectedly
open or close by itself. Make sure that
the glass hatch is fully open and secure
before using the luggage compartment.
Also pay attention to your personal
belongings such as bags and ties.
● When closing the glass hatch, take
extra care to prevent your fingers etc.
from being caught. Also pay attention to
your personal belongings such as bags
and ties.
● When closing the glass hatch, make
sure to press it lightly on its outer sur-
face.

Operation of each component
HIGHLANDER_U (OM0E017U)■
Note for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to
the rear bumper center when the back door is opened.
• The electronic key is on the instrument panel or floor, or in the auxiliary box of the driver's side instrument panel, door pockets or glove box when
the engine is started or engine switch modes are changed.
● Do not leave the electronic key on top of the instrument panel or near t\
he
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the out side, possibly trapping the electronic
key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Even if the electronic key is not inside the vehicle, it may be possible to start
the engine if the electronic key is near the window.
● The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash when the electronic key is
within the effective range. (The doors 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 or unlock sensor while wearing gloves may prevent
lock or unlock operation. Remove the gloves and touch the lock or unlock
sensor again.
● When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following 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.)
• Set the electronic key to battery-saving mode to disable the smart key system. ( →P. 143)

WARNING
■When folding the rear seatbacks down
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Do not fold the seatbacks down while driving.
● Stop the vehicle on level ground, set the parking brake and shift the shift
lever to P.
● Do not allow anyone to sit on a folded seatback or in the luggage compart-
ment while driving.
● Do not allow children to enter the luggage compartment.
● Do not fold down a rear seatback when there are passengers sitting in the
rear seats or when there is luggage placed on the rear seats.
● Be careful not to catch your hand when folding the rear seatbacks.
■ Seat adjustment
● To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.
● Be careful that the seat does not hit passengers or luggage.
● Be careful not to get your hands or feet caught in the seat.
■ After adjusting or returning the seats
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Make sure that the seat and seatback are securely locked in position by
lightly rocking them back and forth.
● Check that the seat belts are not twisted or caught in the seatback.
