Operation of each component
HIGHLANDER_U (OM0E017U)■
When required to leave the vehicle’s key with a parking attendant
Lock the glove box as circumstances demand. ( →P. 461)
Vehicles without a smart key system: Carry the master key for your own use
and provide the attendant with the valet key.
Vehicles with a smart key system: Remove the mechanical key for your own
use and provide the attendant with the electronic key only.
■ If you lose your keys
New genuine keys can be made by your Toyota dealer using a master key
(vehicles without a smart key system) or the other key (vehicles with a smart
key system) and the key number stamped on your key number plate. Keep
the plate in a safe place such as your wallet, not in the vehicle.
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircraft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.

Vehicles without a smart key system
The wireless remote control function may not operate normally in the follow-
ing situations:
● When the wireless 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, cellul ar phone or other wireless communi-
cation device
● When multiple wireless keys are in the vicinity
● When the wireless key is in contact with, or is covered by a metallic object
● When a wireless key (that emits radio waves) is being used nearby

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.

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.

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.
