PRIUS c_U (OM52J11U)
WARNING
●Do not pull on the back door damper stay to close the back door, and do
not hang on the back door damper stay.
Doing so may cause hands to be caught or the back door damper stay to
break, causing an accident.
● If a bicycle carrier or similar heavy object is attached to the back door, it
may suddenly shut again after being opened, causing someone’s hands,
head or neck to be caught and injured. When installing an accessory part
to the back door, using a genuine Toyota part is recommended.
●The back door may suddenly shut 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 com-
partment.
● 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.

PRIUS c_U (OM52J11U)■
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 sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● 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.
■ Notes for the unlocking function
●A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
● Gripping the door handle when wearing a glove may not unlock the door.
Remove the gloves and touch the sensor on the back of the handle again.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
■ 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. Ask your Toyota
dealer for details.
■ To operate the smar t key system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the

1503-3. Adjusting the seats
PRIUS c_U (OM52J11U)
WARNING
■When folding the rear seatbacks down
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Do not fold the seatbacks down while driving.
● Stop the vehicle on level ground, set the parking brake and shift the shift
lever to P.
● Do not allow anyone to sit on a folded seatback or in the luggage compart-
ment while driving.
● Do not allow children to enter the luggage compartment.
● For vehicles with split rear seats, do not allow anyone sit on the rear center
seat if the rear right seat is folded down, as the seat belt buckle for the rear
center seat belt is then concealed under the folded seat and cannot be
used.
● Be careful not to catch your hand when folding the rear seatbacks.
● If it is necessary to detach the head restraints, remove it from the vehicle
or store it securely in the luggage compartment. This will prevent it from
injuring passengers in the event of sudden braking, sudden swerving or an
accident.
● Adjust the position of the front seat before folding down the rear seatbacks
so that the front seat does not interfere with the rear seatbacks when fold-
ing down the rear seatbacks.
