the risk of sliding under the lap belt.
If the seat is too reclined, during an accide nt the lap belt may sl ide past the hips and
apply restraint forces directly to the abdomen or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury. ■

CAUTION
Observe the following precautions to reduce the risk of injury in the event of sudden
braking, sudden swerving or an accident.
Failing to do so may cause death or serious injury. ■
Wearing a seat belt ●
Ensure that all passengers wear a seat belt. ●
Always wear a seat belt properly. ●
Each seat belt should be used by one person only. Do not use a seat belt for more
than one person at on ce, including children.●
Lexus recommends that children be seated in the rear seat and always use a seat
belt and/or an appropriate child restraint system. ●
Do not recline the seat any more than necessary to achieve a proper seating
position. The seat belt is most effective when the occupants are sitting up straight
and well back in the seats. ●
Do not wear the shoulder belt under your arm. ●
Always wear your seat belt low and snug across your hips. If your seat belts cann ot be fastened securely
because they are not long enough, a person-
alized seat belt extender is available from
your Lexus dealer free of charge.

LX570_OM_OM60L21U_(U) CAUTION■
Using a seat belt extender ●
Do not wear the seat belt extender, if you can fasten the seat belt without the
extender. ●
Do not use the seat belt extender when installing a child restraint system, because
the belt will not securely hold the child restraint system, increasing the risk of
death or serious injury in the event of a sudden stop, sudden swerve or accident.●
The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seatin g position other than the one originally
intended.
NOTICE■
When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the extender,
not on the seat belt.
This helps prevent damage to the vehi cle interior and the extender itself.

1271-7. Safety information

Before driving
LX570_OM_OM60L21U_(U) Your vehicle is equipped with AD VANCED AIRBAGS designed based
on the US motor vehicle safety st andards (FMVSS208). The airbag sen-
sor assembly (ECU) controls airbag deployment based on information
obtained from the sensors etc. show n in the system components diagram
above. This information includes cras h severity and occupant informa-
tion. As the airbags deploy, a chemica l reaction in the inflators quickly fills
the airbags with nontoxic 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 front seats, second seats, and parts of the front, center and rear pil-
lars, and roof side rail, may be hot for several minutes. The airbag itself may also
be hot. ●
The windshield may crack. ●
For Safety Connect subscriber s, 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. 7 2 2 )

LX570_OM_OM60L21U_(U) CAUTION■
SRS airbag precautions
●
The SRS front passenger airbag also depl oys 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 ar e safer for infants and children than the
front passenger seat. (  P. 144) ●
If the seat belt extender has been con-
nected to the front seat belt buckles but the
seat belt extender has not also been fas-
tened to the latch plate of the seat belt, the
SRS front airbags will judge that the driver
and front passenger are wearing the seat
belt even though the seat belt has not been
connected. In this case, the SRS front air-
bags may not activate correctly in a colli-
sion, resulting in death or serious injury in
the event of collision. Be sure to wear the
seat belt with the seat belt extender.
