Essential Safety Equipment
If you cannot put all children in the rear seat, at least put the smallest
children in the rear and be sure the largest child up front use s a front-
facing child-restraint system.
NEVER put a rear-facing child-restraint system on the front pas senger
seat whether your vehicle is equ ipped with a occupant classification
sensor or not.
This seat is also not set up for tethered child-restraint syste ms, put
them in one of the rear seat posit ions set up with tether anchors.
Likewise the LATCH child-restraint system cannot be secured in the
front passenger’s se at and should be used in the rear seat.
Do not allow anyone to lean over or against the side window sin ce
your vehicle has side and curt ain air bags, it could cause serious inju-
ries to an out of position occup ant. As children more often sleep in
cars, it is better to pu t them in the rear seat.
If installing the child-restraint system on the front seat is u navoidable,
follow these instructions when using a front-facing child-restraint sys-
tem in the front passenger’s seat.
●To check if your front seats have side air bags:
The vehicle equipped with side air bag will have a “SRS AIRBAG” tag on the
outboard shoulder of the front seats.
● To check if your vehicle has curtain air bags:
The vehicle equipped with curtain air bag will have an “SRS AIR BAG” mark-
ing on the window pillars along the roof edge.
WARNING
■ Always attach the tether strap to the correct tether anchor pos ition
Attaching the tether strap to the incorrect tether anchor position is danger-
ous. In a collision, the tether strap could come off and loosen the child-
restraint system. If the child-restraint system moves it could result in death
or injury to the child.
■ Always install the head restraint and adjust it to the appropriate posi-
tion after removing the child-restraint system
Driving with the head restraint removed is dangerous as impact to the occu-
pant’s head cannot be prevented during emergency braking or in a collision,
which could result in a serious accident, injury or death.
Refer to Head Restraints on P. 30.

1-3. Child Restraint
Push the child-restraint system firmly into the vehicle seat. Be sure
the belt retracts as snugly as possible. A clicking noise from the
retractor will be hear d during retraction if the system is in a utomatic
locking mode. If the belt does not lock the seat down tight, re peat
the previous step and also this one.
Inspect this function before each use of the child-restraint sy stem. You
should not be able to pull the shoulder belt out of the retract or while the
system is in the automatic locking mode. When you remove the ch ild-
restraint system, be sure the belt fully retracts to return the system to
emergency locking mode before occupants use the seat belts.
Seat your child safely in the child-restraint system and secure the
child according to the instructions from the child-restraint sy stem
manufacturer.
Switch the ignition ON and
make sure the front passenger
air bag deactivation indicator
light illuminates after installing a
child-restraint system on the
front passenger seat.
If the front passenger air bag
deactivation indicator light does
not illuminate, remove the child-
restraint system, switch the
ignition to OFF, and then re-
install the child-restraint sys-
tem ( P. 8 2 ) .
Follow the child-restraint system manufacturer’s instructions carefully.
Depending on the type of child-restraint system, it may not employ seat belts
which are in automatic locking mode.

611-3. Child Restraint

Essential Safety Equipment
Your Toyota is equipped with LATCH lower anchors for attachment of
specially designed LATCH child-re straint systems in the rear seats.
Both anchors must be used, otherwise the seat will bounce aroun d
and put the child in danger. Most LATCH child-restraint systems must
also be used in conjunction wi th a tether to be effective. If they have a
tether you must use it to better assure your child’s safety.
WARNING
■ Do not seat a child in a child-r estraint system on the front passenger
seat if the front passenger air ba g deactivation indicator light does not
illuminate
While it is always better to install any child-restraint system on the rear seat,
it is imperative that a child-restraint system ONLY be used on the front pas-
senger seat if the deactivation indicator light illuminates when the child is
seated in the child-restraint system ( P. 82). Seating a child in a child-
restraint system installed on the front passenger seat with the front passen-
ger air bag deactivation indicator light not illuminated is dangerous. If this
indicator light does not illuminate, this means that the front passenger front
and side air bags, and seat belt pretensioners are ready for deployment. If
an accident were to deploy an air bag, a child in a child-restr aint system sit-
ting in the front passenger seat could be seriously injured or killed. If the
indicator light does not illuminate after seating a child in a child-restraint
system on the front passenger seat, seat a child in a child-res traint system
on the rear seat and consult your Toyota dealer as soon as poss ible.
Using LATCH Lower Anchor
WARNING
■Follow the manufacturer’s instructions for the use of the child-restraint
system
An unsecured child-restraint system is dangerous. In a sudden s top or a
collision it could move causing serious injury or death to the child or other
occupants. Make sure the child-restraint system is properly sec ured in place
according to the child-restraint system manufacturer’s instructions.

62
YARIS_YARIS HATCHBACK_OM_OM99V59z_(U)
1-3. Child Restraint
First, adjust the front seat to allow clearance between the chi ld-
restraint system and the front seat ( P. 2 3 ) .
Make sure the seatback is securely latched by pushing it back u ntil
it is fully locked.
WARNING
■ Never attach two child-restraint systems to the same LATCH lowe r
anchor
Attaching two child-restraint systems to the same LATCH lower a nchor is
dangerous. In a collision, one anchor may not be strong enough to hold two
child-restraint system attachments, and it may break, causing s erious injury
or death. If you use the seat position for another child-restra int system when
an outboard LATCH position is occupied, use the center seat bel ts instead,
and the tether if tether-equipped.
■ Make sure the child-restraint system is properly secured
An unsecured child-restraint system is dangerous. In a sudden s top or a
collision it could move causing serious injury or death to the child or other
occupants. Follow the child-restraint system manufacturer’s ins tructions on
belt routing to secure the seat just as you would with a child in it so that
nobody is tempted to put a child in an improperly secured seat later on.
When not in use, remove it from the vehicle or fasten it with a seat belt, or
latch it down to BOTH LATCH lower anchors for LATCH child-restr aint sys-
tems.
■ Make sure there are no seat belts or foreign objects near or ar ound the
LATCH child-restraint system
Not following the child-restraint system manufacturer’s instructions when
installing the child-restraint system is dangerous. If seat bel ts or a foreign
object prevent the child-restraint system from being securely a ttached to the
LATCH lower anchors and the child-restraint system is installed improperly,
the child-restraint system could move in a sudden stop or colli sion causing
serious injury or death to the child or other occupants. When i nstalling the
child-restraint system, make sure there are no seat belts or fo reign objects
near or around the LATCH lower anc hors. Always follow the child-restraint
system manufacturer’s instructions.

Essential Safety Equipment
Expand the open seams on the
rear of the seat bottom slightly
to verify the locations of the
LATCH lower anchors.
The markings above the LATCH
lower anchors indicate the loca-
tions of the LATCH lower anchors
for the attachment of a child-
restraint system.
Remove the head restraint.
Refer to Head Restraints on P. 30.
Secure the child-restraint system using BOTH LATCH lower
anchors, following the child-restraint system manufacturer’s instruc-
tion. Pull on the child-restraint to be sure both anchors are
engaged.
If your child-restraint system came equipped with a tether, tha t
means it is very important to properly secure the tether for ch ild
safety. Please carefully follow the child-restraint system manu fac-
turer’s instructions w hen installing tethers.

WARNING
■Use the tether and tether anchor only for a child-restraint system
Using the tether or tether anchor to secure anything but a chil d-restraint
system is dangerous. This could weaken or damage the tether or tether
anchor and result in injury.
■ Always remove the head restraint and install child-restraint sy stem
Installing a child-restraint system without removing the head restraint is
dangerous. The child-restraint system cannot be installed corre ctly which
may result in death or injury to the child in a collision.

1-4. SRS Air Bags
WARNING
■Seat belts must be worn in air bag equipped vehicles
Depending only on the air bags for protection during an acciden t is danger-
ous. Alone, air bags may not prevent serious injuries. The appr opriate air
bags can be expected to inflate only in the first accident, suc h as frontal,
near frontal or side collisions or roll-over accidents that are at least moder-
ate. Vehicle occupants should always wear seat belts.
■ Children should not ride in the front passenger seat
Placing a child, 12 years or under, in the front seat is danger ous. The child
could be hit by a deploying air bag and be seriously injured or even killed. A
sleeping child is more likely to lean against the door and be h it by the side
air bag in moderate collision to the front-passenger side of th e vehicle.
Whenever possible, always secure a child 12 years and under on the rear
seats with an appropriate child-restraint system for the child’s age and size.
■ Never use a rear-facing child-restraint system in the front sea t with an
air bag that could deploy
■ Do not sit too close to the driver and fron t passenger air bags
Sitting too close to the driver and front passenger air bag modules or plac-
ing hands or feet on them is extremely dangerous. The driver an d front pas-
senger air bags inflate with great force and speed. Serious injuries could
occur if someone is too close. The driver should always hold on to only the
rim of the steering wheel. The front seat passenger should keep both feet
on the floor. Front seat occupants should adjust their seats as far back as
possible and always sit upright against the seatbacks with seat belts worn
properly.
Rear-facing child-restraint systems on
the front seat are particularly dangerous
even though you may feel assured that a
front passenger air bag will not deploy
based on the fact that the front passen-
ger air bag deactivation indicator light
illuminates. The child-restraint system
can be hit by a deploying air bag and
moved violently backward resulting in
serious injury or death to the child.
