341-1. For safe use
Move the height adjuster up and
down as needed until you hear a
click.
When the vehicle is subjected to
a severe frontal or side impact
or rollover, the pretensioners
retract the seat belts of the front
seats and rear outer seats to
securely restrain the occupants.
The pretensioners will not operate
in minor frontal or side impacts, or
rear impacts.
■Replacing the belt after the pre-
tensioner has been activated
If the vehicle is in volved in multiple collisions, the pretensioner will acti-
vate for the first collision, but will not
activate for the second or subse-
quent collisions.
■PCS-linked control
If the PCS (Pre-Collision System)
determines that th e possibility of a
collision with a vehicle is high, the
seat belt pretensioners will be pre-
pared to operate.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 protection in
an accident and cause death or
serious injuries in the event of a
sudden stop, sudden swerve or
accident.
Seat belt pretensioners
(front seats and outboard
rear seats)
WARNING
■Seat belt pretensioners
Observe the following precautions
to reduce the risk of injury in the
event of sudden braking or an
accident.
Failure to do so may result in
death or serious injury.
●Do not place anything, such as
a cushion, on the front passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the seat belt pretensioner
for the front passenger’s seat
may not operate in the event of
a collision.
●If a pretensioner has operated,
the SRS warning light will illumi-
nate. In this situation, the seat
belt cannot be used and must
be replaced by your Toyota
dealer.

421-1. For safe use
WARNING
●Do not attach anything to areas
such as the doors, windshield,
side windows, front or rear pil-
lars, roof side rails and assist
grips. (With the exception of the
speed limit label P.577)
●Do not use seat accessories
which cover the parts from
which the SRS airbags deploy,
as they may inte rfere with infla-
tion of the SRS airbags. Such
accessories may prevent the
SRS airbags from deploying
correctly, may disable the sys-
tem or cause the SRS airbags
to inflate unintentionally, possi-
bly resulting in death or serious
injury.
●Do not strike or apply significant
force to the SRS airbag system
components, front doors or their
surrounding area.
Doing so may cause the SRS
airbags to malfunction.
●Do not touch any components
of the SRS airbags immediately
after the SRS airbags have
deployed (inflated) as they may
be hot.
●If breathing becomes difficult
after the SRS airbags have
deployed, open a door or win-
dow to allow fresh air in, or
leave the vehicle if it is safe to
do so. Wash off any residue as
soon as possible to prevent skin
irritation.
●If a part where an SRS airbag is
stored is damaged or cracked,
have it replaced by your Toyota
dealer.
●Do not place anything, such as
a cushion, on the front passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the SRS front airbags for
the front passenger’s seat may
not deploy in the event of a colli-
sion.
■Modification and disposal of
SRS airbag system compo-
nents
Do not dispose of your vehicle or
perform any of the following modi-
fications without consulting your
Toyota dealer. The SRS airbags
may malfunction or deploy unin-
tentionally, possibly leading to
death or serious injury.

WARNING
●Make sure the “PASSENGER
AIR BAG OFF” indicator light is
not illuminated when using the
seat belt extender for the front
passenger seat. If the “PAS-
SENGER AIR BAG OFF” indi-
cator light is illuminated,
disconnect the extender tongue
from the seat belt buckle, and
reconnect the seat belt. Recon-
nect the seat belt extender after
making sure the “PASSENGER
AIR BAG ON” indicator light is
illuminated. If you use the seat
belt extender while the “PAS-
SENGER AIR BAG OFF” indi-
cator light is illuminated, the
SRS airbags for the front pas-
senger will not activate, which
could cause death or serious
injury in the event of a collision.
●Do not apply a heavy load to the
front passenger seat or equip-
ment (e.g. se atback pocket).
●Do not put weight on the front
passenger seat by putting your
hands or feet on the front pas-
senger seat seatback from the
rear passenger seat.
●Do not let a rear passenger lift
the front passenger seat with
their feet or press on the seat-
back with their legs.
●Do not put objects under the
front passenger seat.
●Do not recline the front passen-
ger seatback so far that it
touches a rear seat. This may
cause the “PASSENGER AIR
BAG OFF” indicator light to be
illuminated, which indicates that
the SRS airbags for the front
passenger will not activate in
the event of a severe accident.
If the seatback touches the rear
seat, return th e seatback to a
position where it does not touch
the rear seat. Keep the front
passenger seatback as upright
as possible when the vehicle is
moving. Reclining the seatback
excessively may lessen the
effectiveness of the seat belt
system.
●If an adult sits in the front pas-
senger seat, the “PASSENGER
AIR BAG ON” indicator light is
illuminated. If the “PASSEN-
GER AIR BAG OFF” indicator is
illuminated, ask the passenger
to sit up straight, well back in
the seat, feet on the floor, and
with the seat belt worn correctly.
If the “PASSENGER AIR BAG
OFF” indicator still remains illu-
minated, either ask the passen-
ger to move to the rear seat, or
if that is not possible, move the
front passenger seat fully rear-
ward.
●When it is unavoidable to install
a forward-facing child restraint
system on the front passenger
seat, install the child restraint
system on the front passenger
seat in the proper order.
(  P.53)
●Do not modify or remove the
front seats.

WARNING
●Do not kick the front passenger
seat or subject it to severe
impact. Otherwise, the SRS
warning light may come on to
indicate a malfunction of the
front passenger occupant clas-
sification system. In this case,
contact your Toyota dealer
immediately.
●Child restraint systems installed
on the rear seat should not con-
tact the front seatbacks.
●Do not use a seat accessory,
such as a cushion and seat
cover, that covers the seat
cushion surface.
●Do not modify or replace the
upholstery of the front seat.
●Adjust the front passenger seat
so that the head restraint does
not touch the ceiling. If the head
restraint is left in contact with
the ceiling, the system may not
detect the front passenger prop-
erly, leading to improper opera-
tion of the airbags.

Exhaust gas precau-
tions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WARNING
Exhaust gases contain harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
■Important points while driving
●Keep the back door closed.
●If you smell exhaust gases in
the vehicle even when the back
door is closed, open the side
windows and have the vehicle
inspected at your Toyota dealer
as soon as possible.
■When parking
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time.
If such a situation cannot be
avoided, park the vehicle in an
open space and ensure that
exhaust fumes do not enter the
vehicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem operating, exhaust gases
may collect and enter the vehi-
cle.
■Exhaust pipe
The exhaust system needs to be
checked periodically. If there is a
hole or crack caused by corro-
sion, damage to a joint or abnor-
mal exhaust noise, be sure to
have the vehicle inspected and
repaired by your Toyota dealer.

Riding with children
Observe the following pre-
cautions when children are
in the vehicle.
Use a child restraint system
appropriate for the child,
until the child becomes
large enough to properly
wear the vehicle’s seat belt.
It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact
with the shift lever, wiper
switch, etc.
 Use the rear door child-pro-
tector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.189, 229)
 Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, back door,
seats, etc.
WARNING
■When children are in the vehi-
cle
Never leave children unattended
in the vehicle, and never allow
children to have or use the key.
Children may be able to start the
vehicle or shift the vehicle into
neutral. There is also a danger
that children ma y injure them-
selves by playing with the side
windows or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.

Points to remember
WARNING
■When a child is riding
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●For effective protection in auto-
mobile accidents and sudden
stops, a child must be properly
restrained, using a seat belt or
child restraint system which is
correctly installe d. For installa-
tion details, refer to the opera-
tion manual enclosed with the
child restraint system. General
installation inst ructions are pro-
vided in this manual.

521-2. Child safety
WARNING
●Toyota strongly urges the use of
a proper child restraint system
that conforms to the weight and
size of the child, installed on the
rear seat. According to accident
statistics, the child is safer when
properly restrained in the rear
seat than in the front seat.
●Holding a child in your or some-
one else’s arms is not a substi-
tute for a child restraint system.
In an accident, the child can be
crushed against the windshield
or between the holder and the
interior of the vehicle.
■Handling the child restraint
system
If the child restrain t system is not
properly fixed in place, the child or
other passengers may be seri-
ously injured or even killed in the
event of sudden braking, sudden
swerving, or an accident.
●If the vehicle were to receive a
strong impact from an accident,
etc., it is possible that the child
restraint system has damage
that is not readily visible. In
such cases, do not reuse the
restraint system.
●Make sure you have complied
with all installation instructions
provided with the child restraint
system manufacturer and that
the system is properly secured.
●Keep the child restraint system
properly secured on the seat
even if it is not in use. Do not
store the child restraint system
unsecured in the passenger
compartment.
●If it is necessary to detach the
child restraint system, remove it
from the vehicle or store it
securely in the luggage com-
partment.

541-2. Child safety
■When installing a child
restraint system to a front
passenger seat
For the safety of a child, install
child restraint system to a rear
seats. When installing child
restraint system to a front pas-
senger seat is unavoidable,
adjust the seat as follows and
install the child restraint system.
 Adjust the seatback angle to
the most upright position.
 Move the front seat fully rear-
ward.
 Move the seat to the upper-
most position
 If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
Otherwise, put the head
restraint in the upper most
position.
When using a child
restraint systemWARNING
■When using a child restraint
system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Never install a re ar-facing child
restraint system on the front
passenger seat even if the
“PASSENGER AIR BAG OFF”
indicator light is illuminated. In
the event of an accident, the
force of the rapid inflation of the
front passenger airbag can
cause death or serious injury to
the child if the rear-facing child
restraint system is installed on
the front passenger seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. A child
restraint system that requires a
top tether strap should not be
used in the front passenger seat
since there is no top tether strap
anchor for the front passenger
seat.
