■Types of collisions that m ay not deploy the SRS airbags
(SRS side and curtain shield airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is
subjected to a collision from the side at certain angles, or a collision to the
side of the vehicle body other than the passenger compartment.
The SRS side and curtain shield airbags do not generally inflate if the vehicle
is involved in a rear collision, if it ro lls over, or if it is involved in a low-speed
side or low-speed frontal collision. ● Collision from the side to the vehicle
body other than the passenger compart-
ment
● Collision from the side at an angle
● Collision from the rear
● Vehicle rollover

passenger seat and activates or deactivates the devices for the
front passenger.

WARNING
■Front passenger occupant classification system precautions
●Do not recline the front passenger seatback so far that it touches a rear
seat. This may cause “OFF” of the “PASSENGER AIR BAG” indicator to
be illuminated, which indicates that the SRS airbags for the front passen-
ger will not activate in the event of a severe accident. If the seatback
touches the rear seat, return the seatback to a position where it does not
touch the rear seat. Keep the front passenger seatback as upright as pos-
sible 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 passenger seat, “ON” of the “PASSENGER AIR
BAG” indicator is illuminated. If “OFF” of the “PASSENGER AIR BAG” indi-
cator 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 “OFF” of the
“PASSENGER AIR BAG” indicator still remains illuminated, either ask the
passenger to move to the rear seat, or if that is not possible, move the
front passenger seat fully rearward.
● 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 pas-
senger seat in the proper order. ( P. 63)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction of the
front passenger occupant classification system. In this case, contact your
Toyota dealer immediately.
● Child restraint systems installed on the rear seat should not contact the
front seatbacks.
● Do not use a seat accessory, such as a cushion and seat cover, that cov-
ers the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.

Child restraint systems
Studies have shown that installing a child restraint on a rear seat is
much safer than installing one to the front passenger seat.
●Choose a child restraint system that suits your vehicle and is appro-
priate to the age and size of the child.
● For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual.
( P. 6 3 )
A child restraint system for a small child or baby must itself be
properly restrained on the seat with the LATCH anchors or the
lap portion of the lap/shoulder belt.
The laws of all 50 states of the U.S.A. and Canada now require
the use of child restraint systems.

WARNING
■Child restraint precautions
●For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
depending on the age and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an accident, the child can be
crushed against the windshield, or between you and the vehicle’s interior.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent statistics, the child is safer when properly restrained in the rear seat
than in the front seat.
● Never install a rear-facing child restraint system on the front passenger
seat even if the “OFF” of the “PASSENGER AIR BAG” indicator is illumi-
nated. 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 pas-
senger 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.
Adjust the seatback as upright as possible and always move the seat as
far back as possible even if the “OFF” of the “PASSENGER AIR BAG” indi-
cator is illuminated, because the front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seri-
ously injured.
● 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 sea t, front and rear pillars or roof side
rails from which the SRS side airbags or SRS curtain shield airbags deploy
even if the child is seated in the child restraint system. It is dangerous if
the SRS side 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.

WARNING
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead 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 restraint 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 child restraint system unsecured in the pas-
senger 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.

Installing child restraints
Child restraint LATCH anchors
LATCH anchors are provided for
the outboard rear seats. (Buttons
displaying the location of the
anchors are attached to the seats.)
Seat belts equipped with a child
restraint locking mechanism
(ALR/ELR belts except driver’s
seat belt) (P. 3 2 )
Anchor brackets (for top tether
strap)
An anchor bracket is provided for
each rear seat.
Follow the child restraint system manufacturer’s instructions.
Firmly secure child restraints to the 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 (Lower Anchors and Tethers
for Children) system.
