For safety and security
For children or smaller-than-average
people, slide the seat belt comfort
guide forward so that the shoulder belt
does not sit close to the person’s neck.
The pretensioner helps the seat belt to
quickly restrain the occupant by
retracting the seat belt when the vehi-
cle is subjected to certain types of
severe frontal collision.
The front seat pretensioners also acti-
vate when the vehicle is subjected to
certain types of severe side collision.
The pretensioner does not activate in the event of a minor frontal impact, a minor side
impact, a rear impact or a vehicle rollover.
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if you
lean forward too quickly. A slow, easy motion w ill allow the belt to extend so that you can
move around fully.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is used to
hold the child restraint system (CRS) firmly. To free the belt again, fully retract the belt
and then pull the belt out once more. ( →P. 57)

■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
●Use a child restraint system appropriate for the child, until the child becomes large
enough to properly wear the vehicle’s seat belt. ( →P. 53)
●When the child becomes large enough to properly wear the vehicle’s seat belt, follow
the instructions regardin g seat belt usage. (→P. 30)
■Replacing the belt after the pr etensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the first
collision, but will not activate for th e second or subsequent collisions.
■Seat belt extender
If your seat belts cannot be fastened securely
because they are not long enough, a personal-
ized seat belt extender is available from your
Lexus dealer free of charge.
WARNING
Observe the following precautions to reduce the risk of injury in the event of sudden
braking, sudden swerving or an accident.
Failure to do so may cause death or serious injury.
■Wearing a seat belt
●Ensure that all passeng ers 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 once, 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.
●To achieve a proper seating position, do not recline the seat more than necessary. The
seat belt is most effective when the occupa nts 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.

WARNING
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed in
the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts. Do
not use a damaged seat belt until it is replaced. Damaged seat belts cannot protect an
occupant from death or serious injury.
●Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correct ly, immediately contact your Lexus dealer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in a
serious accident, even if there is no obvious damage.
●Do not attempt to install, remove, modify, disassemble or dispose of the seat belts.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate handling
may lead to inco rrect operation.
■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 in stalling a child restraint system because the
belt will not securely hold the child restra int system, increasing the risk of death or
serious injury in the event of an accident.
●The personalized extender may not be safe on another vehicle, when used by another
person, or at a different seating 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 vehicle interior and the extender itself.

WARNING
■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 infant s and children can be killed or seriously
injured by a deploying airbag. An infant or child who is too small to use a seat belt
should be properly secured using a chil d restraint system. Lexus strongly recom-
mends that all infants and children be placed in the rear seats of the vehicle and prop-
erly restrained. The rear se ats are safer for infants and children than the front
passenger seat. ( →P. 53)
●If the seat belt extender has been connected
to the front seat belt buckles but the seat belt
extender has not also been fastened to the
latch plate of the seat belt, the SRS front air-
bags will judge that the driver and front pas-
senger are wearing the seat belt even though
the seat belt has not been connected. In this
case, the SRS front airbags may not activate
correctly in a collision, resulting in death or
serious injury in the event of a collision. Be
sure to wear the seat belt with the seat belt
extender.
●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.

■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 ma y not recognize him/her as an adult
depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt
*4: For some children, child in seat, child in booster seat or child in convertible seat,
the system may not recognize him/her as a child. Factors which may affect this can
be the physique or posture.
*5: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint sy stem should only be installed on the front passenger
seat when it is unavoidable. (→ P. 53)
*6: In case the indicator light is not illuminated, consult this manual on how to install the
child restraint system properly. ( →P. 57)

WARNING
■Front passenger occupant classification system precautions
Observe the following precautions regarding the 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 plate has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Make sure the “AIR BAG OFF” indicator li ght is not illuminated when using the seat
belt extender for the front passenger seat. If the “AIR BAG OFF” indicator light is illu-
minated, disconnect the extender tongue from the seat belt buckle, and 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 SRS airbags for the front passenger will not
activate, which could cause death or seri ous injury in the event of a collision.
●Do not apply a heavy load to the front passenger seat or equipment (e.g. seatback
pockets).
●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 passeng er 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
SRS airbags for th e front passenger will no t activate 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 effec-
tiveness of the seat belt system.
●If an adult sits in the fron t passenger seat, the “AIR BAG ON” indicator light is illumi-
nated. 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 correctly. If
the “AIR BAG OFF” indicator still remain s illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front passenger seat fully
rearward.
●When it is unavoidable to in stall a forward-facing child re straint system on the front
passenger seat, install the ch ild restraint system on the front passenger seat in the
proper order. ( →P. 57)
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise, the
SRS warning light may come on to indica te a malfunction of the front passenger
occupant classification system. In this cas e, contact your Lexus dealer immediately.
