Airbag system components
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 seat’s 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.Knee airbags

CAUTION
■SRS airbag precautions
●If the vinyl cover is put on the area where the SRS knee airbag will deploys, be
sure to remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components shown on P. 62.
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 airbag has deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any
residue 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 pillar garnish, are damaged or cracked, have them replaced by your Lexus
dealer.
●Do not attach anything to or lean anything
against areas such as the dashboard, steer-
ing wheel pad or lower portion of the
instrument panel.
These items can become projectiles when
SRS driver, front passenger and knee air-
bags deploy.
●Do not attach anything to areas such as the
door, windshield glass, side door glass,
front and rear pillars, roof side rail or assist
grip.
●Do not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and seri-
ously injure or kill you, should the SRS cur-
tain shield airbag deploy.

■There is a malfunction in the system
*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 passen-
ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. (P. 77)
*5: In case indicator is not illuminated, consult this manual as for installing
the child restraint system properly. (P. 8 0 )

CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding front passenger occupant classifica-
tion 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 AIRBAG OFF indicator light is not illuminated when using the seat
belt extender for the front passenger seat. If the AIRBAG 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
AIRBAG ON indicator light is illuminated. If you use the seat belt extender while
the AIRBAG OFF indicator light is illuminated, the front passenger airbag, side
airbag on the front passenger side and front passenger knee airbag may not acti-
vate correctly, which could cause death or serious injury in the event of collision.
●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.
●Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the AIRBAG 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 AIRBAG ON indicator light is illu-
minated. If the AIRBAG 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 AIRBAG OFF indicator still remain 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.

CAUTION
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix
the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child may be injured or
even killed in the event of sudden braking or an accident.
●When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child's shoulder. The belt should be kept away
from the child's neck, but not so that it could fall off the child's shoulder. Failing to
do so may result in death or serious injury in the event of an accident or sudden
braking.
●Ensure that the belt and tab are securely locked and the seat belt is not twisted.
●Push and pull the child seat in different directions to be sure it is secure.
●Follow all installation instructions provided by the child restraint system manufac-
turer.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Only put a forward facing or booster child
seat on the front seat when unavoidable.
When installing a forward facing or
booster child restraint on the front passen-
ger seat, move the seat as far back as possi-
ble. Failing to do so may result in death or
serious injury if the airbags deploy (inflate).

CAUTION
■If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning light not
come on when you start the engine, this could mean that these systems are not
available to help protect you in an accident, which could result in death or serious
injury. Have the vehicle inspected by your Lexus dealer immediately if this occurs.
■Warning lights
Warning lights inform the driver of malfunctions in any of the vehi-
cle’s systems. (P. 3 3 9 )
*: These lights turn on when the engine switch is turned to IG-ON mode
to indicate that a system check is being performed. They will turn off
after the engine is started, or after a few seconds. There may be a mal-
function in a system if a light does not come on, or if the lights do not turn
off. Have the vehicle inspected by your Lexus dealer.

Fuel pump shut off system
Follow the procedure below to restart the engine after the system is acti-
vated.
Switch to ACC mode or OFF.
Restart the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked on to the ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or an airbag
inflates upon collision, the fuel pump shut off system stops supplying fuel to
the engine.
