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 on the instrument panel, luggage cover, floor or in the glove box when the engine is started or engine switch modes are
changed.
● The doors may unlock if a large amount of water splashes on the door
handle, such as in the rain or in a car wash. (The doors will automatically
be locked after approximately 30 seconds if the doors are not opened
and closed.)
● Gripping the door handle when wearing a glove may not unlock 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 entry function. (Use the wireless remote control to
unlock the doors.)
■ 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.
■ Security feature
If a door is not opened within approximately 30 seconds after the vehicle is

■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 64)
■ 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
become large enough to properly wear the vehicle’s seat belt. ( P. 107)
● When the child becomes large enough to properly wear the vehicle’s
seat belt, follow the instructions on P. 64 regarding seat belt usage.
■ Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will active for
the first collision, but will not active for the second or subsequent collisions.

CAUTION
■Seat belt pretensioners
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the seat belt becomes locked: it cannot
be further extended, nor will it return to the stowed position. The seat belt
cannot be used again and must be replaced at your Toyota dealer.
■ 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 injury in the event of a collision.
● 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.

SRS airbag precautions
● The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
the safest for infants and children. (P. 107)
● If the seat belt extender has been con-
nected to the driver’s seat belt buckle
but the seat belt extender has not also
been fastened to the latch plate of the
driver’s seat belt, the SRS driver’s air-
bag system will judge that the driver is
wearing the seat belt even though the
seat belt has not been connected. In
this case, the driver’s airbag may not
activate correctly in a collision, resulting
in death or serious injury in the event of
collision. Be sure to wear the seat belt
with the seat belt extender.
