The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact, a rear impact or a vehicle roll-
over.
For Russia and Kazakhstan
The pretensioners help the seat belts to
quickly restrain the occupants by

Front impact sensors
Side impact sensors (door)
The main SRS airbag system components are shown above. The SRS airbag sys-
tem is controlled by the airbag sensor assembly. As the airbags deploy, a chemical
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, parts of the front and rear pillars, and roof side rails, may
be hot for several mi nutes. The airbag itself may also be hot.
●The windshield may crack.
●Vehicles with ERA-GLONASS: If the
SRS airbags deploy, the system is
designed to send an emergency call* to
the Public Safety Answering Point (PSAP), 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 emergency and helps
to dispatch the necessary emergency services. ( P.299)*: In some cases, the call cannot be made.
( P.300)
■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 20 - 30
km/h [12 - 18 mph] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situa-
tions: • 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.
■SRS airbag deployment conditions (SRS
side and curtain shield airbags)
●The SRS side and curtain shield airbags
will deploy in the event of an impact that exceeds the set thresh old level (the level
of force corresponding to the impact force produced by an approximately 1500 kg [3300 lb.] vehicle colliding with
the vehicle cabin from a direction per- pendicular to the vehicle orientation at an approximate speed of 20 - 30 km/h [12 -
18 mph]).
●Both SRS curtain shield airbags may
deploy in the event of a severe side colli- sion.
●For Russia and Kazakhstan: Both SRS curtain shield airbags will deploy in the event of vehicle rollover.
●Both SRS curtain shield airbags may also deploy in the event of a severe frontal col-
lision.
■Conditions under which the SRS air- bags may deploy (inflate), other than a collision
The SRS front airbags and SRS curtain shield airbags may also deploy if a serious

WARNING
■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.Since the risk zone for the driver’s air-
bag is the first 50 - 75 mm (2 - 3 in.) of inflation, placing yourself 250 mm (10 in.) 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 250 mm (10 in.) 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 250 mm (10 in.) distance, even with the driver seat
all the way forward, simply by reclining the back of the 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 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 above, while still maintaining
control of the foot pedals, steering wheel,
and your view of the instrument panel
controls.
●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.

WARNING
●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 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.48)
●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 door, the roof side rail or the front, side and rear pil-
lars.
●Do not allow anyone to kneel on the
passenger seat toward the door or put their head or hands outside the vehi-cle.
●Do not attach anything to or lean any-thing against areas such as the dash-
board, steering wheel pad and lower portion of the instrument panel. These items can become projectiles
when the SRS driver, front passenger and knee airbags deploy.

For safety and security
WARNING
■When installing a child restraint sys- tem
For safety reasons, always install a child restraint system in a rear seat. In the event that the rear seat cannot be used,
the front seat can be used as long as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment (inflation) may cause serious
injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off sys- tem is set to “ON”.If it is left off, the airbag may not deploy in
the event of an accident, which may result in serious injury or even death.
Riding with children
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.
( P.152)
 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.

tems can fit in all vehicles. Before
using or purchasing a child restraint
system, check the compatibility of
the child restraint system with seat
positions.
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 can-
not 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.
 The use of a Lexus genuine child
restraint system is recom-
mended, as it is safer to use in this
vehicle. Lexus genuine child
restraint systems are made specif-
ically for Lexus vehicles. They can
be purchased at any authorized
Lexus retailer or Lexus autho-
rized repairer, or any reliable
repairer.
