1-7. Safety information

Before driving
Your vehicle is equipped with
ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls ai rbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This inform ation includes crash severity and
occupant information. As the air bags deploy, a chemical reaction in
the inflators quickly fills the airbag s with non-toxic gas to help restrain
the motion of the occupants.
■ If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The windshield may crack.

CAUTION
■
SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
the safest for infants and children. ( P. 90)
●If the seat belt extender has been con-
nected to the front seat belt buckles but
the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags may not activate correctly in a
collision, resulting in death or serious
injury in the event of a collision. Be sure
to wear the seat belt with the seat belt
extender.
●Do not sit on the edge of the seat or
lean against the dashboard.

CAUTION
■
Child restraint precautions
●Do not use the seat belt extender when installing a child restraint system
on the front or rear passenger seat. If installing a child restraint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause death or seri-
ous injury to the child or other passengers in the event of a sudden stop,
sudden swerve or accident.
● Do not allow the child to lean his/her head or any part of his/her body
against the door or the area of the seat , front and rear pillars or roof side
rail from which the side airbags or curtain shield airbags deploy even if the
child is seated in the child restraint system. It is dangerous if the side air-
bags and curtain shield airbags inflate, and the impact could cause death
or serious injury to the child.
● Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop, sudden swerve or accident.
■ Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the
belt becomes twisted around a child’s neck, it will not be possible to pull the
belt out leading to choking or other serious injuries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ When the child restrain t system is not in use
● Keep the child restraint system properly secured on the seat even if it is
not in use.
Do not store the restraint 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 compartment. This will prevent it
from injuring passengers in the event of a sudden stop, sudden swerve or
accident.

1-7. Safety information
Installing child restraints
Follow the child restraint system manufacturer's instructions. Firmly
secure child restraints to the r ear seats using the LATCH anchors or
a seat belt. Attach the top tether strap when installing a child
restraint.
The lap/shoulder belt can be used if your child restraint system is
not compatible with the LATCH (Low er Anchors and Tethers for Chil-
dren) system.
Seat belts equipped with a
child restraint locking mecha-
nism (ALR/ELR belts except
driver’s seat belt) ( P. 48)
Child restraint LATCH anchors
LATCH anchors are provided
for the outside rear seats. (But-
tons displaying the location of
the anchors are attached to the
seats.)
Anchor bracket (for top tether
strap)
Anchor brackets are provided
for all rear seats.

98 1-7. Safety information
While pushing the child seat
down into the rear seat, allow the
shoulder belt to retract until the
child seat is securely in place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
■Forward facing Convertible seat
Place the child seat on the seat
facing the front of the vehicle.
Run the seat belt through the
child seat and insert the plate
into the buckle. Make sure that
the belt is not twisted.
Fully extend the shoulder strap
and then allow it to retract
slightly into the ALR lock mode.
Lock mode allows the seat belt to
retract only.

no slack in the belt, pull the belt to
check that it cannot be extended.
If the child restraint has a top te
ther strap, the top tether strap
should be latched onto the top tether strap anchors.
■ Booster seat
Place the booster seat on the
seat facing the front of the vehi-
cle.
Sit the child in the booster seat.
Fit the seat belt to the booster
seat according to the manufac-
turer's instructions and insert the

■Laws and regulations pertaining to anchorages
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 specifica-
tions can be used.
This vehicle is designed to conform to the SAE J1819.

102 1-7. Safety information
CAUTION
■When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR
lock mode: ( P. 49)
ALR mode causes the belt to tighten only which could cause injury or dis-
comfort to the child.
■ When installing a child restraint system
Follow the directions given in the child restraint system installation manual
and fix the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of sudden
braking, sudden swerving or an accident.
●If the driver's seat interferes with the
child restraint system and prevents it
from being attached correctly, attach
the child restraint system to the right-
hand rear seat.
● Adjust the front passenger seat so that
it does not interfere with the child
restraint system.
● Only put a forward-facing or booster
child seat on the front seat when
unavoidable. When installing a forward-
facing or booster child seat on the front
passenger seat, move the seat as far
back as possible even if the “AIR BAG
OFF” indicator light is illuminated. Fail-
ing to do so may result in death or seri-
ous injury if the airbags deploy (inflate).

CAUTION
■
When installing a child restraint system
●When a booster seat is installed, always ensure that the shoulder belt is
positioned across the center of the child's shoulder. The belt should be
kept away from the child's neck, but not so that it could fall off the child's
shoulder. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
● Ensure that the belt and tab are securely locked and the seat belt is not
twisted.
● Push and pull the child seat from side to side and forward to be sure it is
secure.
● After securing a child restraint system, never adjust the seat.
● Follow all installation instructions provided by the child restraint system
manufacturer.
■ Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the
seat belt will not securely hold the child restraint system, which could cause
death or serious injury to the child or other passengers in the event of sud-
den braking, sudden swerving or an accident.
■ To correctly attach a child r estraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint. Make sure the child restraint system is securely attached, or it may
cause death or serious injury to the child or other passengers in the event of
a sudden stop, sudden swerve or an accident.
