1-5. Refueling
CAUTION
lDo not allow anyone that has not discharged static electricity from their body to
come close to an open fuel tank.
lDo not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
lDo not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
lDo not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.
nWhen refueling
Securely insert the fuel nozzle into the fuel filler neck. If fuel is added with the nozzle
slightly lifted away from the fuel filler neck, the automatic shut off function may not
operate, resulting in fuel overflowing from the tank.
nWhen replacing the fuel cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle.
Doing so may cause a fire or other incident which may result in death or serious
injury.
NOTICE

Before driving
SRS 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’s seat position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc.

1-7. Safety information
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.
nIf the SRS airbags deploy (inflate)
lBruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
lA loud noise and white powder will be emitted.
lParts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, and parts of the front and rear pillars, and roof side rails, may
be hot for several minutes. The airbag itself may also be hot.
lThe windshield may crack.
lFor Safety Connect subscribers, if the SRS airbags deploy or in the event of a
severe rear-end 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 emer-
gency and helps to dispatch the necessary emergency services. (→P. 4 3 6 )

CAUTION
nFront 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.
lWear the seat belt properly.
lMake sure the front passenger’s seat belt tab has not been left inserted into the
buckle before someone sits in the front passenger seat.
lMake 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
collision.
lDo not apply a heavy load to the front passenger seat or equipment.
lDo 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.
lDo not let a rear passenger lift the front passenger seat with their feet or press on
the seatback with their legs.
lDo not put objects under the front passenger seat.
