Notes 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
signals will be shown up to two consecutive times. After this, no recogni-
tion signals will be given.
● If the door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. Place the key
in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle 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 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.

CAUTION
■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 fall closed
again after it is opened.
● When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.
● 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.
● Use caution when opening or closing the back door in windy weather as it
may move abruptly in strong wind.
●The back door may fall if it is not
opened fully. It is more difficult to open
or close the back door on an incline
than on a level surface, so beware of
the back door unexpectedly opening or
closing by itself. Make sure that the
back door is fully open and secure
before using the luggage compartment.
● When closing the back door, take extra
care to prevent your fingers etc. from
being caught.
● When closing the back door, make sure
to press it lightly on its outer surface. If
the back door handle is used to fully
close the back door, it may result in
hands or arms being caught.

CAUTION
■Seat adjustment
● To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary. 
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.
● After adjusting the seat, make sure that the seat is locked in position.
● Never allow anyone to touch seatback lock release levers while the vehi-
cle is moving.
● If anyone is in the vicinity, make sure they are clear of the seat back path
and let them know that the seat is about to move.
■ After returning the seatback to the upright position
Make sure the seatback is securely locked by pushing it forward and rear-
ward. Failure to do so may result in death or serious injury.
NOTICE
■To prevent the seat lock mechanism malfunction
Do not use the seatback angle adjustment lever and seatback lock release
lever at the same time. If they are used together, the seat lock mechanism
may be damaged.

recline the seat more than necessary. 
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury in the event of\
an acci-
dent.
Adjustments should not be made while driving as the seat may unexpectedly
move and cause the driver to lose control of the vehicle.
■ After returning the rear seatback to the upright position

■When not using the rear outboard seat belts
■ Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
● Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt. ( P. 126)
● When the child becomes large enough to properly wear the vehicle’s
seat belt, follow the instructions on P. 78 regarding seat belt usage.
■ Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate
for the first collision, but will not activate for the second or subsequent colli-
sions.
■ Seat belt extender
Pass the outer seat belts through the seat
belt hangers.
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your Scion
dealer free of charge.

CAUTION
■Using a seat belt extender
● Do not wear the seat belt extender if you can fasten the seat belt without
the extender.
● Do not use the seat belt extender when installing a child restraint system
because the belt will not securely hold the child restraint system, increas-
ing the risk of death or serious injury in the event of an accident.
● The personalized extender may not be safe on another vehicle, when
used by another person, or at a different seating position other than the
one originally intended.
NOTICE
■When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the
extender, not on the seat belt. 
This helps prevent damage to the vehicle interior and the extender itself.
