WARNING
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle. This could lead to an acc ident, resulting in
death or serious injury.
■ When installing the driver’s floor mat
● Do not use floor mats designed for other models or different mo del year
vehicles, even if they are Toyota Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
● Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
● With the hybrid system stopped and the
shift position in P, fully depress each
pedal to the floor to make sure it does
not interfere with the floor mat.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
● Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce
the effectiveness of the seat belt and head restraint.
● Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the s eat
tracks and stop the seat from locking in place. This may lead t o an acci-
dent and the adjustment mechanism may also be damaged.
● Always observe the legal speed limit when driving on public roads.
● When driving over long distances, take regular breaks before yo u start to
feel tired.
Also, if you feel tired or sleepy while driving, do not force y ourself to con-
tinue driving and take a break immediately.

For safety and security
Push the seat belt shoulder
anchor down while pressing the
release button.
Push the seat belt shoulder
anchor up.
Move the height adjuster up and
down as needed until you hear a
click.
The pretensioners help the seat
belts to quickly restrain the occu-
pants by retracting the seat belts
when the vehicle is subjected to
certain types of severe frontal or
side collision or a vehicle rollover.
The pretensioners do not activate
in the event of a minor frontal
impact, a minor side impact or a
rear impact.
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on imp act. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
■ Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and the n retracted
even slightly, the belt is locked in that position and cannot be extended. This
feature is used to hold the child restraint system (CRS) firmly . To free the belt
again, fully retract the belt and then pull the belt out once m ore.

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. 58)
● When the child becomes large enough to properly wear the vehicle’s seat
belt, follow the instructions regarding seat belt usage. ( P. 30)
■ Replacing the belt after the pr etensioner has been activated
If the vehicle is involved in multiple collisions, the pretensi oner will activate for
the first collision, but will not activate for the second or su bsequent collisions.
■ 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.
WARNING
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or serious injury.
■ Wearing a seat belt
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat m ore than
necessary. The seat belt is most effective when the occupants a re sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.

WARNING
■Pregnant women
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 30)
■ When children are in the vehicle
 P. 6 9
■ 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 t he sensor
from detecting the passenger’s weight properly. As a result, th e seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will c ome on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
Obtain medical advice and wear the seat
belt in the proper way. ( P. 30)
Women who are pregnant should posi-
tion the lap belt as low as possible over
the hips in the same manner as other
occupants, extending the shoulder belt
completely over the shoulder and avoid-
ing belt contact with the rounding of the
abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.

WARNING
■Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the cen ter of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of prot ection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 31)
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or bu ckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fray ing, and loose
parts. Do not use a damaged seat belt until it is replaced. Dam aged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not t wisted.
If the seat belt does not function correctly, immediately conta ct your Toyota
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious dam age.
● Do not attempt to install, remove, modify, disassemble or dispo se of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling may lead to incorrect operation.
■ 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 restr aint 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 acci dent.
● The personalized extender may not be safe on another vehicle, when
used by another person, or at a different seating position othe r than the
one originally intended.
