US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system compon ents diagram above. This information
includes crash severity and occupant info rmation. As the airbags deploy, a chemi-
cal reaction in the inflators quickly fills the airbags with non-toxic gas to help
restrain the motion of the occupants.
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.
●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 may be hot for sev-
eral minutes. The airbag itself may also be
hot.
●The windshield may crack.
●All of the doors will be unlocked.
(  P.97)
●The brakes and stop lights will be con-
trolled automatically. ( P.219)
●The interior lights will turn on automati-
cally. ( P.244)
●The emergency flashers will turn on auto-
matically. ( P.306)
●Fuel supply to the engine will be stopped.
( P.313)
●For Lexus Enform Safety Connect sub-
scribers, if any of the following situations
occur, 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” but-
ton) and an agent will attempt to speak
with the occupants to ascertain the level
of emergency and assi stance required. If
the occupants are unable to communi-
cate, the agent automatically treats the
call as an emergency and helps to dis-
patch the necessary emergency services.
(  P.56)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear- end collision.
■SRS airbag deployment
conditions (SRS
front airbags)
●The SRS front airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to an approximately 12 - 18
mph [20 - 30 km/h] frontal collision with
a fixed wall that does not move or
deform).
However, this threshold velocity will be
considerably higher in the following situ-
ations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can
move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle underrides, or goes
under, the bed of a truck
●Depending on the type of collision, it is
possible that only the seat belt preten-
sioners will activate.
●The SRS front airbags for the front pas-
senger will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the SRS front airbags for the
front passenger may deploy if luggage is
put in the seat, even if the seat is unoccu-
pied.
■SRS airbag deployment conditions (SRS
side airbags)
The SRS side airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to the impact force produced by
an approximately 3300 lb. [1500 kg] vehi-
cle colliding with the vehicle cabin from a
direction perpendicular to the vehicle ori-
entation at an approximate speed of 12 - 18
mph [20 - 30 km/h]).

For safety and securityWARNING
■SRS airbag precautions
Observe the following precautions
regarding the SRS airbags.
Failure to do so may cause death or seri-
ous injury.
●The driver and all passengers in the
vehicle must wear their seat belts
properly.
The SRS airbags are supplemental
devices to be used with the seat belts.
●The SRS driver airbag deploys with
considerable force, and can cause
death or serious injury especially if the
driver is very close to the airbag. The
National Highway Traffic Safety
Administration (NHTSA) advises:
Since the risk zone for the driver’s air-
bag is the first 2 - 3 in. (50 - 75 mm) of
inflation, placing yourself 10 in. (250
mm) from your driver airbag provides
you with a clear margin of safety. This
distance is measured from the center
of the steering wheel to your breast-
bone. If you sit less than 10 in. (250
mm) away now, you can change your
driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many
drivers can achieve the 10 in. (250
mm) distance, even with the driver
seat all the way forward, simply by
reclining the back of the seat some-
what. If reclining the back of your seat
makes it hard to see the road, raise
yourself by using a firm, non-slippery
cushion, or raise the seat if your vehi-
cle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag
toward your chest instead of your
head and neck.
The seat should be adjusted as recom-
mended by NHTSA above, while still
maintaining control of the foot pedals,
steering wheel, and your view of the
instrument panel controls.

WARNING
●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.
●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 passen-
ger 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 air-
bag. 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 safer for
infants and children than the front pas-
senger seat. ( P.46)
●Do not sit on the edge of the seat or
lean against the dashboard.
●Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
●Do not allow the front seat occupants
to hold items on their knees.
●Do not lean against the front door.
●Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehi-
cle.

WARNING
■Front passenger occupant classifica-
tion system precautions
Observe the following precautions
regarding the front passenger occupant
classification system.
Failure to do so may cause death or seri-
ous injury.
●Wear the seat belt properly.
●Make sure the fron t passenger’s seat
belt plate has not been left inserted
into the buckle before someone sits in
the front passenger seat.
●Make sure the “AIR BAG OFF” indi-
cator light is not illuminated when
using the seat belt extender for the
front passenger seat. If the “AIR BAG
OFF” indicator light is illuminated, dis-
connect the extender tongue from the
seat belt buckle, and reconnect the
seat belt. Reconnect the seat belt
extender after making sure the “AIR
BAG ON” indicator light is illumi-
nated. If you use the seat belt extender
while the “AIR BAG OFF” indicator
light is illuminated, the SRS airbags for
the front passenger will not activate,
which could cause death or serious
injury in the event of a collision.
●Do not apply a heavy load to the front
passenger seat or equipment (e.g.
seatback pocket or armrest).
●Do not put weight on the front passen-
ger seat by putting your hands or feet
on the front passenger seat seatback
from the rear passenger seat.
●Do not let a rear passenger lift the
front passenger seat with their feet or
press on the seatback with their legs.
●Do not put objects under the front pas-
senger seat.
●Do not recline the front passenger
seatback so far that it touches a rear
seat. This may cause the “AIR BAG
OFF” indicator 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 position where it
does not touch the rear seat. Keep the
front passenger seatback as upright as
possible 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, the “AIR BAG ON” indicator
light is 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 co rrectly. If the “AIR
BAG OFF” indicator still remains illu-
minated, 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 for-
ward-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.48)
●Do not modify or remove the front
seats.
●Do not kick the front passenger seat or
subject it to severe impact. Otherwise,
the SRS warning light may come on to
indicate a malfunction of the front pas-
senger occupant clas sification system.
In this case, contact your Lexus 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 covers the
seat cushion surface.

■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller adult sits in the
front passenger seat, the system may not re cognize him/her as an adult depending on
his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt
*4: For some children, child in se at, child in booster seat or child in convertible seat, the sys-
tem may not recognize him/her as a child. Factors which may affect this can be the phy-
sique or posture.
*5: Never install a rear-facing ch ild restraint system on the front passenger seat. A forward-
facing child restraint system sh ould only be installed on the front passenger seat when it
is unavoidable. ( P.48)

Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child , until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the window lock switch to
avoid children operating the
power window accidentally.
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, trunk, seats
etc.
WARNING
■When children are in the vehicle
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 may injure
themselves by playing with the windows
or other features of the vehicle. In addi-
tion, heat build-up or extremely cold
temperatures inside the vehicle can be
fatal to children.
Child restraint systems
Before installing a child restraint
system in the vehicle, there are pre-
cautions that need to be observed,
different types of child restraint sys-
tems, as well as installation meth-
ods, 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 installation method
that is in the operation manual
enclosed with the restraint system.
