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 accident, resulting in
death or serious injury.
■ When installing the driver’s floor mat
● Do not use floor mats designed for other models or different model 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 seat
tracks and stop the seat from locking in place. This may lead to 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 you start to
feel tired.
Also, if you feel tired or sleepy while driving, do not force yourself to con-
tinue driving and take a break immediately.

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.
The pretensioners do not activate
in the event of a minor frontal
impact, a minor side impact, a rear
impact or a vehicle rollover.

■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. 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.
■ 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. 5 4 )
● When the child becomes large enough to properly wear the vehicle’s seat
belt, follow the instructions regarding seat belt usage. ( P. 34)
■ 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 collisions.
■ Seat belt regulations
If seat belt regulations exist in the country where you reside, please contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer for seat belt repl acement or installation.
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 more than
necessary. The seat belt is most effective when the occupants are 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. 34)
■ When children are in the vehicle
 P. 6 9
■ Seat belt pretensioners
If the pretensioner has activated, the SRS warning light will come on. In that
case, the seat belt cannot be used again and must be replaced at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
Obtain medical advice and wear the seat
belt in the proper way. ( P. 34)
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 center 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 protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 35)
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious damage.
● Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer. Inap-
propriate handling may lead to incorrect operation.

The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. As
the airbags deploy, a chemical reaction in the inflators quickly fills the
airbags with non-toxic gas to help restrain the motion of the occu-
pants.
