Except for Russia and Kazakhstan
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
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.
■Replacing the belt after the preten-
sioner has been activated
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the first collision, but will not activate for the second or subsequent collisions.
WARNING
■When using the seat belt guide
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.Failure to do so may cause death or seri-
ous injury.
●Always make sure that the belt is not twisted, and runs freely through the guide.
●Regardless of whether the guide is
used or not, always secure the seat belt guide button.
●Do not hang from or pull the guide forcefully.

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

impact occurs to the underside of your vehicle. Some examples are shown in the illustration.
●Hitting a curb, edge of pavement or hard surface
●Falling into or jumping over a deep hole
●Landing hard or falling
For Russia and Kazakhstan: The SRS curtain
shield airbags may also deploy under the situations shown in the illustration.
●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 generally
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, when-
ever a collision of any type causes sufficient forward deceleration of the vehicle, deploy-ment of the SRS front airbags may occur.
●Collision from the side
●Collision from the rear
●Vehicle rollover
■Types of collisions that may 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.
●Collision from the side to the vehicle body other than the passenger compart-
ment
●Collision from the side at an angle
The SRS side airbags do not generally
inflate if the vehicle is involved in a frontal or rear collision, if it rolls over, or if it is involved in a low-speed side collision.
●Collision from the front
●Collision from the rear
●Vehicle rollover
The SRS curtain shield airbags (except for Russia and Kazakhstan) do not generally
inflate if the vehicle is involved in a rear colli-

sion, if it rolls over, or if it is involved in a low- speed side or low-speed frontal collision.
●Collision from the rear
●Vehicle rollover
For Russia and Kazakhstan: The SRS curtain shield airbags do not ge nerally 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 colli-
sion.
●Collision from the rear
●Pitching end over end
■When to contact any authorized Lexus retailer or Lexus authorized repairer, or
any reliable repairer
In the following cases, the vehicle will
require inspection and/or repair. Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer
as soon as possible.
●Any of the SRS airbags have been
inflated.
●The front of the vehicle is damaged or
deformed, or was involv ed in an accident that was not severe enough to cause the SRS front airbags to inflate.
●A portion of a door or its surrounding area is damaged, deformed or has had a hole made in it, or the vehicle was
involved in an accident that was not severe enough to cause the SRS side and curtain shield airbags to inflate.
●The pad section of the steering wheel, dashboard near the front passenger air-
bag or lower portion of the instrument panel is scratched, cracked, or otherwise damaged.
●The surface of the seats with the SRS side
airbag is scratched, cracked, or other- wise damaged.

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.
