●Make sure the “AIR BAG OFF”
indicator light is not illuminated
when using the seat belt
extender for the front passenger
seat. If the “AIR BAG OFF” indi-
cator light is illuminated, discon-
nect the extender tongue from
the seat belt buckle, and recon-
nect the seat belt. Reconnect
the seat belt extender after
making sure the “AIR BAG ON”
indicator light is illuminated. If
you use the seat belt extender
while the “AIR BAG OFF” indi-
cator light is illuminated, the
SRS airbags for the front pas-
senger may not activate, which
could cause death or serious
injury in the ev ent of a collision.
●D o n o t a p p l y a h e a v y l o a d t o t h e
front passenger seat or equip-
ment (e.g. seatback 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 rea r passenger lift
the front passenger seat with
their feet or press on the seat-
back with their legs.
●Do not put objec ts under the
front passenger seat.
●Do not recline t he front passen-
ger seatback so far that it
touches the rear seat. This may
cause the “AIR BAG OFF” indi-
cator 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 the
seatback to a pos ition where it
does not touch the rear seat.
Keep the front passenger seat-
back as upright as possible
when the vehicle is moving.
Reclining the seatback exces-
sively may lessen the effective-
ness of the seat belt system.
●If an adult sits i n the front pas-
senger seat, the “AIR BAG ON”
indicator light i s illuminated. If
the “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 “AIR BAG OFF” indicator
still remains illumi nated, either
ask the passenger to move to
the rear seat, or if that is not
possible, move the front pas-
senger seat fully rearward.
●When it is unavoidable to install
a forward-facing c hild restraint
system on the front passenger
seat, install the child restraint
system on the front passenger
seat in the proper order.
(
P. 4 9 )
●Do not modify or remove the
front seats.
●Do not kick the front passenger
seat or subject it to severe

For safety and security
Exhaust gas precau-
tions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WA R N I N G
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases 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 trunk lid closed.
●If you smell exhaust gases in
the vehicle even when the trunk
lid is closed, open the 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 on 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.

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 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.108, 129)
 Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, trunk, seats,
etc.
WA R N I N G
■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 win-
dows or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.


Prioritize and observe the
warnings, as well as the laws
and regulations for child
restraint systems.
 Use a child restraint system
until the child becomes large
enough to properly wear the

and size of the child.
Child restraint sys-
tems
Before installing a child
restraint system in the vehi-
cle, there are precautions
that need to be observed,
different types of child
restraint systems, as well as
installation methods, etc.,
written in this manual.
Use a child restraint system
when riding with a small child
that cannot properly use a
seat belt. For the child’s
safety, install the child
restraint system to a rear seat.
Be sure to follow the installa-
tion method that is in the oper-
ation manual enclosed with
the restraint system.

Points to remember
WA R N I N G
■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 instruction is pro-
vided in this manual.

481-2. Child safety
COROLLA HV_U
WA R N I N G
●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 restrai nt system is not
properly fixed in place, the child or
other passengers may be seri-
ously injured or e ven 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 possib le 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 trunk.
