351-1. For safe use
1
For safety and security
Seat belts
Make sure that all occu-
pants are wearing their seat
belts before driving the
vehicle.
WARNING
Observe the following precautions
to reduce the risk of injury in the
event of sudden braking, sudden
swerving or an accident.
Failure 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 prop-
erly.
●Each seat belt should be used
by one person only. Do not use
a seat belt for more than one
person at once, including chil-
dren.
●Toyota recommends that chil-
dren 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.
●Always wear the belt with the
shoulder portion over the out-
side armrest and the lap portion
under the outside armrest.
■Pregnant women
Obtain medical advice and wear
the seat belt in the proper way.
(  P.36)
Women who are pregnant should
position the lap belt as low as
possible over the hips in the same
manner as other occupants,
extending the shoulder belt com-
pletely over the shoulder and
avoiding belt contact with the
rounding of the abdominal area.
If the seat belt is not worn prop-
erly, 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.
■People suffering illness
Obtain medical advice and wear
the seat belt in the proper way.
(  P.36)
■When children are in the vehi-
cle
 P.67
■Seat belt damage and wear
●Do not damage the seat belts
by allowing the belt, plate, or
buckle to be jammed in the
door.

561-1. For safe use
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 is 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.

571-2. Child safety
1
For safety and security
1-2.Child safety
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 sliding door child-
protector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.142, 204)
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, the moon roof (if
equipped) or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.
