the sliding door is about to open or close.
● If the power sliding door system is turned off with the main switch while the
sliding door is operating automatica lly, the automatic operation is stopped.
The sliding door then has to be operated manually. Take extra care when
on an incline, as the sliding door may open or close unexpectedly.
● If the operating conditions of the power sliding door are no longer met, a
buzzer may sound and the sliding door may stop opening or closing. The
sliding door then has to be operated manually. Take extra care when on an

tem) or IGNITION ON mode (vehicles with a smart key system) or the
engine is started during automatic operation
● Do not attach any accessories other than genuine Toyota parts to the
power sliding door. The power sliding door may not operate, causing itself
to malfunction, or the power sliding door may close again after it is
opened.

3-2. Opening, closing and locking the doors
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 operate 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.
■ Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.
● Remove any heavy loads, such as snow and ice, from the back door
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.
● When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.

that the back door is fully open and
secure before using the luggage com-
partment.

Operation of each component
■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.

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

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.
