For safety and security
Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
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 information. As the airbags deploy, a
chemical reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the moti on of the occupants.

■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental device s to be used with the seat belts.
●The SRS driver airbag deploys with consider able force, and can cause death or seri-
ous 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 airbag 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 breastbone. 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 com- fortably.
• Slightly recline the back of the seat. Al though vehicle designs vary, many drivers
can achieve the 10 in. (250 mm) distance, even with the driver seat all the way for-
ward, simply by reclining the back of th e seat somewhat. 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 vehicle has that feature.
• If your steering wheel is ad justable, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommen ded by NHTSA above, while still maintain-
ing control of the foot pedals, steering whee l, and your view of the instrument panel
controls.

■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 re strained 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 system. Lexus strongly recom-
mends that all infants and children be placed in the rear seats of the vehicle and prop-
erly restrained. The rear seats are safe r for infants and children than the front
passenger seat. ( P. 5 8 )
●If the seat belt extender has been connected
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 air-
bags will judge that the driver and front pas-
senger are wearing the seat belt even though
the seat belt has not been connected. In this
case, the SRS front airbags may not activate
correctly in a collision, resulting in death or
serious injury in the event of 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.
●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.

■SRS airbag precautions
●Do not lean against the door, the roof side rail
or the front, side and rear pillars.
●Do not allow anyone to kneel on the passen-
ger seats toward the door or put their head or
hands outside the vehicle.
●Do not attach anything to or lean anything
against areas such as the dashboard, steering
wheel pad and lower portion of the instru-
ment panel.
These items can become projectiles when the
SRS driver, front passenger and knee airbags
deploy.

■SRS airbag precautions
●Do not hang coat hangers or other hard objects on the coat hooks. All of these items
could become projectiles and may cause death or serious injury, should the SRS cur-
tain shield ai rbags deploy.
●If the vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it.
●Do not use seat accessories which cover th e parts where the SRS side airbags inflate
as they may interfere with inflation of th e airbags. Such accessories may prevent the
side airbags from activating correctly, disa ble the system or cause the side airbags to
inflate accidentally, resulting in death or serious injury.
●Do not strike or apply signif icant levels of force to the area of the SRS airbag compo-
nents.
Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicl e if it is safe to do so. Wash off any resi-
due as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front, side and rear pillar garnishes, are damaged or cracked, have them replaced by
your Lexus dealer.
●Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, th e SRS front airbags for the front passenger
may not deploy in the event of a collision.
●Do not attach anything to areas such as a
door, windshield glass, side door glass, front,
side or rear pillars, roof side rail and assist
grip.

■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) 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, parts of the front, side and rear pillars and roof side rails, may be hot for sev-
eral minutes. The airbag itself may also be hot.
●The windshield may crack.
●For Lexus Enform Safety Connect subscribers, 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 vehicl e’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 communi-
cate, the argent automatically treats the call as an emergency and helps to dispatch the
necessary emergency services. ( P. 4 5 1 )

■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
old level (the level of force corresponding 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 situations:
• 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 possib le that only the seat belt pretensioners will
activate.
●The SRS front airbags for the front passenger will not activate if there is no passenger
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the se at is unoccupied.
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags wi ll deploy in the event of an impact that
exceeds the set threshol d level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 12 - 18 mph [20 - 30 km/h]).
●The SRS curtain shield airbags will deploy in the event of vehicle rollover.
●The SRS side and curtain shield airbags will deploy in the event of a severe frontal colli-
sion.
■Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags and SRS side and curtain shield airbags may also deploy if a seri-
ous impact occurs to the underside of your vehicle. Some examples are shown in the
illustration.
The SRS curtain shield airbags may also deploy under the situations shown in the illustra-
tion.
●Hitting a curb, edge of pavement or hard sur-
face
●Falling into or jumping over a deep hole
●Landing hard or falling
●The angle of vehicle tip-up is marginal
●The vehicle skids and hits a curb stone

■Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not gene rally inflate if the vehicle is involved in a side or rear
collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a
collision of any type causes sufficient forwar d deceleration of the vehicle, deployment of
the SRS front airbags may occur.
●Collision from the side
●Collision from the rear
●Vehicle rollover

LX570_OM_OM60N01U_(U)
■Types of collisions that may not deploy the SRS airbags
(SRS side and curtain shield airbags)
The SRS side and curtain shield airbags may no t 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 airbags do not generally inflate if the vehicle is involved in a rear collision, if
it rolls over, or if it is involved in a low-speed side or low-speed frontal collision.
The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a rear
collision, if it pitches end over end, 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 compartment
●Collision from the side at an angle
●Collision from the rear
●Vehicle rollover
●Collision from the rear
●Pitching end over end

shield airbags and seat belt pretension-
ers will turn back on automatically each
time the engine switch is turned to
IGNITION ON mode.
■This switch only should be used
In a situation where the inflation is not desired (such as during extreme off road driving).
■Operating conditions when the “RSCA OFF” indicator is on
●The curtain shield airbags and seat belt pretensioners will not activate in a vehicle roll-
over.
●The curtain shield airbags will activate in a severe side impact.
●The seat belt pretensioners will activate in a severe frontal collision.

■For normal driving
Make sure the “RSCA OFF” indicator is not turn ed on. If it is left on, the curtain shield
airbag will not activate in the event of an accident, which may result in death or serious
injury.
