NOTICE
■Back door damper stays
The back door is equipped with damper stays that hold the back door in
place.
Observe the following precautions.
Failure to do so may cause damage to the back door damper stay, resulting
in malfunction.
●Do not place your hand on the damper stay or apply lateral forces to it.
■ To prevent back door closer malfunction
Do not apply excessive force to the back door while the back door closer is
operating.
■ To prevent damage to the power back door
●Make sure that there is no ice between the back door and frame that
would prevent movement of the back door. Operating the power back door
when excessive load is present on the back door may cause a malfunc-
tion.
● Do not apply excessive force to the back door while the power back door
is operating.
● Take care not to damage the sensors (installed on the right and left edges
of the power back door) with a knife or other sharp object. If the sensor is
disconnected, the power back door will not operate in automatic operation.
●Do not attach any foreign objects, such
as stickers, plastic sheets, or adhesives
to the damper stay rod.
● Do not touch the damper stay rod with
gloves or other fabric items.
● Do not attach any accessories other
than genuine Toyota parts to the back
door.

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)

function mode
On/off
When the automatic anti-glare
function is in on mode, the indica-
tor illuminates.
The function will set to on mode
each time the engine switch is
turned to “ON” position (vehicles
without a smart key system) or
IGNITION ON mode (vehicles with
a smart key system).
Pressing the button turns the function to off mode. (The indicator also turns
off.)
■ To prevent sensor error (vehicles with auto anti-glare inside rear view
mirror)
Indicator
To ensure that the sensors operate prop-
erly, do not touch or cover them.
WARNING
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and cause an accident,
resulting in death or serious injury.

■Daytime running light system (if equipped)
●Bulb type: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically whenever the
engine is started and the parking brake is released with the headlight switch
off or in the “AUTO” position. (illuminate dimmer than the headlights) Day-
time running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
LED type: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically whenever the
engine is started and the parking brake is released with the headlight
switch off. Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
