Before driving
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety st andards (FMVSS208). The airbag sen-
sor assembly (ECU) controls airbag deployment based on information
obtained from the sensors etc. show n in the system components diagram
above. This information includes crash severity and occupant informa-
tion. As the airbags deploy, a chemica l reaction in the inflators quickly fills
the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.
■SRS warning light
This warning light system monitors the airb ag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, dr iver's seat belt buckle switch, front pas-
senger occupant classification system (ECU and sensors), “AIR BAG ON” indica-
tor light, “AIR BAG OFF” indicator light, fr ont passenger’s seat belt buckle switch,
seat belt pretensioner assemblies, airbags, interconnecting wiring and power
sources. ( P. 464)
■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 , airbag cover and inflator) as well as
the front seats, and parts of the front pill ar, rear pillar and roof side rail, may be
hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Safety Connect subscriber s, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency call to
the response center, notifying them of the vehicle’s location (without needing to
push the “SOS” button) and an agent will attempt to speak with the occupants
to ascertain the level of emergency and assistance required. If the occupants
are unable to communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. ( P. 363)

1-7. Safety information
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 airbag as possible with
the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infants and children can be killed or seri-
ously 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 system. Lexus 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. 115)
●If the seat belt extender has been con-
nected to the front seat belt buckles but the
seat belt extender has not also been fas-
tened to the latch plate of the seat belt, the
SRS front airbags will judge that the driver
and front passenger are wearing the seat
belt even though the seat belt has not been
connected. In this case, the SRS front air-
bags may not activate correctly in a colli-
sion, resulting in death or serious injury in
the event of a collision. Be sure to wear the
seat belt with the seat belt extender.

CAUTION
■Child restraint precautions
●Lexus strongly urges the use of a proper child restraint system that conforms to
the 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.
●Never install a rear-facing child restraint system on the front passenger seat even
if the “AIR BAG OFF” indicator light is illuminated. In the event of an accident, the
force of the rapid inflation of the front passenger airbag can cause death or seri-
ous 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 passenger
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 possi-
ble and always move the seat as far back as possible even if the “AIR BAG OFF”
indicator light is illuminated, because th e front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seriously
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 serious injury to the child or other
passengers in the event of a sudden stop, sudden swerve or collision.
●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 pillar, rear pillar 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 airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all inst allation instructions provided by the
child restraint manufacturer and that the sy stem is properly secured. If it is not
secured properly, it may cause death or seri ous injury to the child in the event of a
sudden stop, sudden swerve or an accident.

118
1-7. Safety information
CAUTION
■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 secu red 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 trunk. This will prevent it from injuring passengers in the
event of a sudden stop, sudden swerve or an accident.

Before driving
Installing child restraints
Follow the child restraint system manufacturer's instructions. Firmly
secure child restraints to the rear 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 com-
patible with the LATCH (Lower Anchor s and Tethers for Children) system.
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.)
Seat belts equipped with a child
restraint locking mechanism
(ALR/ELR belts except driver’s
seat belt) (P. 66)
Anchor bracket (for top tether
strap)
Anchor brackets are provided
for all rear seats.

Before driving
While pushing the child seat down
into the rear seat, allow the shoul-
der 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 belt and
allow it to retract to put it in lock
mode.
Lock mode allows the seat belt to
retract only.

While pushing the child seat 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.
If the child restraint has a top tether 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 vehicle.
Sit the child in the booster seat. Fit
the seat belt to the booster seat
according to the manufacturer's
instructions and insert the plate
into the buckle. Make sure that the
belt is not twisted.
Check that the shoulder belt is cor-
rectly positioned over the child's
shoulder, and that the lap belt is as
low as possible. (
