50 1-2. Key information
PRIUS_U (OM47668U) U.S.A.
■To operate the 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 outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not func-
tion.)
■ Note for the smart key system
● 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 near the ground or in a high place, or too close to the rear bumper center when the back door is locked or unlocked.
• The electronic key is on the instrument panel, luggage cover, floor or in the glove box when the hybrid system is started or “POWER” switch
modes are changed.
● 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
electronic key can be used to unlock the vehicle.
● Even if the electronic key is not inside the vehicle, it may be possible to
start the hybrid system if the electronic key is near the window.
● 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.
● 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 key is kept near the vehicle while it is being washed, water applied
to a door handle may cause the door to lock and unlock repeatedly. In
this event, place the key in a location 6 ft. (2 m) or more from the vehicle,
taking care not to lose the key.

●
If the key is inside the vehicle while it is being washed, water applied to a
door handle may cause a buzzer to sound. In this event, locking all doors
will cause the buzzer to stop sounding.
● It may not be possible to lock the doors if the sensor area is covered by
mud, ice, snow etc. In this event, try locking again after cleaning the
area, or lock by touching the sensor area on the underside of the door
handle.
● Fingernails may scrape against the door during operation of the door
handle. Be careful not to injure fingernails or damage the surface of the
door.
● Gripping the door handle when wearing a glove may not unlock or lock
the door.
● If the wireless remote control is used to lock the doors when the elec-
tronic 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.)
● A sudden approach to the effective range or door handle operation may
prevent the doors from being unlocked. In this case, return the door han-
dle to the original position and check that the doors unlock before pulling
the door 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 dr iven 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. 587)

CAUTION
■
Operating the back door
Observe the following precautions. 
Failure to do so may cause parts of the body to be caught, resulting in seri-
ous 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 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.

■People suffering illness
Obtain medical advice and wear the seat belt in the proper way.
■ Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
● Use a child restraint system appropriately for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt. ( P. 132)
● When the child becomes large enough to properly wear the vehicle’s
seat belt, follow the instructions on P. 85 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
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your Toyota
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 a sudden stop, sudden
swerve or 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.
■ Precaution for pre-collision seat belts (if equipped)
Do not rely on the pre-collision system to avoid accidents. Always pay atten-
tion to the surrounding conditions, and drive safely and responsibly.
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.
