The main SRS airbag system components are shown above. The SRS air-
bag system 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.
CAUTION
■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 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 airbag 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 breastbone. 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 fi rm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, t ilt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still maintaining con-
trol of the foot pedals, steering wheel, and your view of the instrument panel con-
trols.

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 safer for infants and children than the
front passenger seat. ( P. 72)
●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 pillars.

■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 seats, parts of the front 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.
●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. 504)
*: In some cases, the call cannot be made. (P. 506)
■SRS airbag deployment conditions (SRS front airbags and SRS seat cushion air-
bag)
●The SRS front airbags and SRS seat cushion airbag will deploy in the event of an
impact that exceeds the set threshold level (the level of force corresponding 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 pretension-
ers will activate.
●Front passenger occupant classification system: The SRS front passenger airbag
will not activate, if there is no passenger sitting in the front passenger seat. How-
ever, the SRS front passenger airbag may deploy, if luggage is put in the seat, or the
seat belt is fastened, even if the seat is unoccupied.

Your vehicle is equipped with a front passenger occupant classification
system. This system detects the conditions of the front passenger seat
and activates or deactivates the devices for the front passenger.

*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 recognize him/her as a child
depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt
*3: When a larger child who has outgrown a child restraint system sits in the front
passenger seat, the system may recognize him/her as an adult depending on
his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front passenger seat. A
forward-facing child restraint system should only be installed on the front pas-
senger seat when it is unavoidable. ( P. 72)
*5: In case the indicator light is not illuminated, consult this manual on how to
install the child restraint system properly. ( P. 89)
*6: Activated only in cases of side impact
CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classi-
fication system.
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Do not put weight on the front passenger 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 passenger seat.
