Operation of each component
WARNING
●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 heavy 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 accessory part to the back door, ask your Toyota dealer for details.
■ Jam protection function (vehicles with power back door)
Observe the following precautions.
Failure to do so may cause death or serious injury.
●Although the back door stops closing when the jam protection function
detects an object, take extra care as you may still be injured if part of your
body is already caught.
● Never use any part of your body to intentionally activate the jam protection
function.
● The jam protection function may not work if something gets caught just
before the back door fully closes. Be careful not to catch fingers or any-
thing else.
● The jam protection function may not work depending on the shape of the
object that is caught. Be careful not to catch fingers or anything else.

Operation of each component
■Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from
discharging.
●When the entry function has not been used for 5 days or more
● When the electronic key has been left within approximately 6 ft. (2 m) of the
vehicle for 10 minutes or more
● If the entry function has not been used for 14 days or more, the vehicle can-
not be unlocked by a door other than the driver’s door. To unlock the vehicle,
grip the driver’s door handle or use the wireless remote control or the
mechanical key.
The system will resume operation when...
● The vehicle is locked using the lock sensor when carrying the electronic key
on your person.
● The vehicle is locked/unlocked using the wireless remote control. ( P. 1 1 1 )
● The vehicle is locked/unlocked using the mechanical key. ( P. 588)
■ Conditions affecting operation
P. 1 1 9
■ Notes 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 on the instrument panel, floor or in the 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 the
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 outside, 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.
● 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 smart key system. (Use the wireless remote control to
unlock the doors.)
● If power slide door is unable to operate due to prohibition by the power slid-
ing door main switch, the door unlock and open operation will not be per-
formed. ( P. 124)

3-2. Opening, closing and locking the doors
■Note for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock 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. Place the key in a posi-
tion 6 ft. (2 m) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play 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, or
use the lock sensor on the lower part of the door handle.
● Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.
■ Notes for the unlocking function
●Gripping the front door handle when wearing a glove may not unlock or lock
the door.
● A sudden approach to the effective range or door handle operation may pre-
vent the doors from being unlocked. In this case, return the door handle to
the original position and check that the doors have unlocked before pulling
the door handle.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after one of the front door handles is gripped or
one of sliding door handles is pulled.
■ When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic key within 6 ft.
(2 m) of the vehicle.
● The smart key system can be deactivated in advance. ( P. 629)
