WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Before driving
● Make sure that the back door is fully closed. If the back door is not fully
closed, it may open unexpectedly while driving and hit near-by objects or
luggage in the luggage compartment may be thrown out, causing an acci-
dent.
● Do not allow children to play in the luggage 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, head, or neck to be caught by the closing back door.
■ Important points while driving
Never let anyone sit in the luggage compartment. In the event of sudden
braking, sudden swerving or a collision, they are susceptible to death or
serious injury.

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.

Operation of each component
HIGHLANDER_U (OM0E017U)■
Battery-saving function
The battery-saving function will be activated in order to prevent the electronic
key battery and the vehicle battery from being discharged while the vehicle is
not in operation for a long time.
●In the following situations, the smart key system may take some time to
unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of
the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.
● If the smart key system has not been used for 14 days or longer, the doors
cannot be unlocked at any doors except the driver’s door. In this case, take
hold of the driver’s door handle, or use the wireless remote control or the
mechanical key, to unlock the doors.
■ Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.
Press twice while pressing and
holding . Confirm that the electronic
key indicator flashes 4 times.
While the battery-saving mode is set, the
smart key system cannot be used. To
cancel the function, press any of the elec-
tronic key buttons.

HIGHLANDER_U (OM0E017U)■
Conditions affecting operation
The smart key system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and engine immobi-
lizer system from operating properly. (Ways of coping: →P. 635)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
● When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
● When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When other wireless keys (that emit radio waves) are being used nearby
● When carrying the electronic key together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If window tint with a metallic content or metallic objects are attached to the
rear window
● When the electronic key is placed near a battery charger or electronic
devices

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)
