The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi- cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover. The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.
■
Replacing the belt after the preten-
sioner has been activated
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.Adjusting the seat belt shoulder

WARNING■
Adjustable shoulder anchor
Always make sure th e shoulder belt is
positioned across the center of your
shoulder. The belt should be kept away
from your neck, but not falling off your
shoulder. Failure to do so could reduce
the amount of protection in an accident
and cause death or serious injuries in the
event of a sudden stop, sudden swerve or
accident. ( → P.31)

WARNING■
Seat belt pretensioners
Observe the following precautions to
reduce the risk of in jury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury. ●
Do not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result , the seat belt pre-
tensioner for the front passenger’s seat
may not activate in the event of a colli-
sion.
●
If the pretensioner has activated, the
SRS warning light will come on. In that
case, the seat belt cannot be used
again and must be replaced at your
Lexus dealer.

LEXUS NX300h Owners Manu-
al_USA_OM78212U WARNING●
If the seat belt extender has been con-
nected 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 airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags 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.
●
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 passen-
ger seat should be as far from the air-
bag as possible with the seatback
adjusted, so the front passenger sits
upright.
●
Improperly seated and/or restrained
infants 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 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 are safer for
infants and children than the front pas-
senger seat. ( → P.47) ●
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.
●
Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
●
Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehi-
cle.

For safety and security WARNING■
Front passenger occupant classifica-
tion system precautions
Observe the following precautions
regarding the front passenger occupant
classification system. Failure to do so may
cause death or serious injury. ●
Wear the seat belt properly.●
Make sure the fron t 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” indi-
cator light is not illuminated when
using the seat belt extender for the
front passenger seat. If the “AIR BAG
OFF” indicator light is illuminated, dis-
connect 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 illumi-
nated. 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 serious
injury in the event of a collision.●
Do not apply a heavy load to the front
passenger seat or equipment (e.g.
seatback pocket).
●
Do not put weight on the front passen-
ger 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 pas-
senger 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 SRS airbags
for the front passenger will not 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 effectiveness of the
seat belt system. ●
If an adult sits in the front passenger
seat, the “AIR BAG ON” indicator
light is illuminated. 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 co rrectly. If the “AIR
BAG OFF” indicator still remains illu-
minated, 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 install a for-
ward-facing child re straint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
( → P.50)
●
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
indicate a malfunction of the front pas-
senger occupant clas sification system.
In this case, contact your Lexus dealer
immediately.
●
Child restraint systems installed on the
rear seat should not contact the front
seatbacks.
●
Do not use a seat accessory, such as a
cushion and seat cover, that covers the
seat cushion surface.

Safety information for chil-
dren Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child, until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the rear door child-protector
lock or the window lock switch to
avoid children opening the door
while driving or operating the
power window accidentally.
( → P.109, 145)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, back door,
seats etc. WARNING
■
When children are in the vehicle
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof (if equipped) or other fea-
tures of the vehicle. In addition, heat
build-up or extremely cold temperatures
inside the vehicle can be fatal to children.

Points to remember WARNING■
When a child is riding
Observe the following precautions. Fail-
ure to do so may result in death or seri-
ous injury. ●
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. ●
Lexus strongly ur ges the use of a
proper child restrain t system that con-
forms to the size of the child, installed
on the rear seat. According to acci-
dent statistics, the child is safer when
properly restrained in the rear seat
than in the front seat.
●
Holding a child in your or someone
else’s arms is not a substitute for a child
restraint system. In an accident, the
child can be crushe d against the wind-
shield or between the holder and the
interior of the vehicle.
●
Place one child to a child restraint sys-
tem and then secure the child with the
harness of the child restraint system.
