Your vehicle is equipped with “ADVANCED AIRBAGS” designed based
on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver’s seat position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc.
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
●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, and parts of the front pillar and roof side rail, may be hot for
several minutes. The airbag itself may also be hot.
●The windshield may crack.
●For vehicles with Safety Connect: For Safety Connect subscribers, if the SRS
airbags deploy or in the event of a severe collision, 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” 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. 4 3 3 )

CAUTION
■SRS airbag precautions
Observe the following precautions regarding the 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. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver 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
comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many driv-
ers 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 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 recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

*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 large 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 and posture.
*4: Never install a rear-facing child restraint system on the front passen-
ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. 
(P. 1 2 4 )
*5: In case the indicator is not illuminated, consult this manual on how to
install the child restraint system properly. (P. 1 2 8 )
CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classifi-
cation system.
Failure to do so may cause death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt tab has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Make sure the “AIR BAG OFF” indicator light is not illuminated when using the
seat belt extender for the front passenger seat. If the “AIR BAG OFF” indicator
light is illuminated, disconnect the extender tongue from the seat belt buckle,
then reconnect the seat belt. Reconnect the seat belt extender after making sure
the “AIR BAG ON” indicator light is illuminated. If you use the seat belt extender
while the “AIR BAG OFF” indicator light is illuminated, the front passenger air-
bag, side airbag on the front passenger side and front passenger knee airbag may
not activate correctly, which could cause death or serious injury in the event of a
collision.

CAUTION
■Front passenger occupant classification system precautions
●Do not apply a heavy load to the front passenger seat or equipment.
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback from the rear seat.
●Do not let a rear seat 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.
●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 passenger’s airbags will not deploy 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 illu-
minated. 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 cor-
rectly. If the “AIR BAG OFF” indicator still remains illuminated, either ask the pas-
senger 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 forward-facing child restraint system on the
front passenger seat, install the child restraint system on the front passenger seat
in the proper order. (P. 1 2 8 )
●Do not modify or remove the front seat.
●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 in the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
●Child restraint systems installed on the rear seat should not contact the front seat-
backs.

■Selecting an appropriate child restraint system
●Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt.
●If a child is too large for a child restraint system, sit the child on a rear seat and
use the vehicle’s seat belt. (P. 7 5 )
CAUTION
■Using a child restraint system
The use of a child restraint system not suitable for the vehicle may not properly
secure the infant or child, resulting in death or serious injury.
■Child restraint precautions
●For effective protection in automobile accidents and sudden stops, a child must
be properly restrained, using a seat belt or child restraint system depending on
the age and size of the child. Holding a child in your arms is not a substitute for a
child restraint system. In an accident, the child can be crushed against the wind-
shield, or between you and the vehicle’s interior.
●Lexus strongly urges the use of a proper child restraint system that conforms to
the size of the child, installed on the rear seat. According to accident statistics, the
child is safer when properly restrained in the rear seat than in the front seat.
●Never install a rear-facing child restraint system on the front passenger seat even
if the “AIR BAG OFF” indicator light is illuminated. In the event of an accident, the
force of the rapid inflation of the front passenger airbag can cause death or seri-
ous injury to the child if the rear-facing child restraint system is installed on the
front passenger seat.
●A forward-facing child restraint system may be installed on the front passenger
seat only when it is unavoidable. A child restraint system that requires a top tether
strap should not be used in the front passenger seat since there is no top tether
strap anchor for the front passenger seat. Adjust the seatback as upright as possi-
ble and always move the seat as far back as possible even if the “AIR BAG OFF”
indicator light is illuminated, because the front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seriously
injured.
