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 restraint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
(  P.51)
●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.

WARNING
●Do not modify or replace the uphol-
stery of the front seat.
Exhaust gas precautions
Harmful substance to the human
body is contained in exhaust gases
if inhaled.
WARNING
Exhaust gases contain harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
to enter the vehicle and may lead to an
accident caused by light-deadness, or
may lead to death or a serious health
hazard.
■Important points while driving
●Keep the back door closed.
●If you smell exhaust gases in the vehi-
cle even when the back door is closed,
open the windows and have the vehi-
cle inspected at your Lexus dealer as
soon as possible.
■When parking
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine.
●Do not leave the vehicle with the
engine running for a long time. If such
a situation cannot be avoided, park the
vehicle in an open space and ensure
that exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
exhaust gases may collect and enter
the vehicle.

For safety and security
■When installing a child restraint
system to a front passenger seat
For the safety of a child, install child
restraint systems to a rear seats. When
installing child restraint system to a
front passenger seat is unavoidable,
adjust the seat as follows and install the
child restraint system.
 Move the front seat fully rearward. If
the passenger seat height can be
adjusted, move it to the upper most
position.
 Adjust the seatback angle to the
most upright position. When install-
ing a forward-facing child seat, if
there is a gap between the child seat
and the seatback, adjust the seat-
back angle until good contact is
achieved.
When installing a forward-facing child
seat, if there is a gap between the child seat
and the seatback, adjust the seatback
angle until good contact is achieved.
If the head restraint interferes with
your child restraint system, and the
head restraint can be removed,
remove the head restraint. Other-
wise, put the head restraint in the
upper most position.
When using a child restraint sys-
tem
WARNING
■When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●Never install a rear-facing child
restraint system on the front passenger
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of
an accident, the force of the rapid infla-
tion of the front passenger airbag can
cause death or serious injury to the
child if the rear-facing child restraint
system is installed on the front passen-
ger seat.
●A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable. A
child restraint system that requires a
top tether strap should not be used in
the front passenger seat since there is
no top tether strap anchor for the front
passenger seat.

521-2. Child safety
LEXUS NX300 Owners Manual_USA_M78389_en
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt.
■Installing child restraint system
using a seat belt (child restraint
lock function belt)
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.
WARNING
●A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, move the seat as far back as pos-
sible, and raise the seat to the upper
most position, even if the “AIR BAG
OFF” indicator light is illuminated. If
the head restraint interferes with the
child restraint system installation and
the head restraint can be removed,
remove the head restraint.
●Do not allow the child to lean his/her
head or any part of his/her body
against the door or the area of the seat,
front or rear pillars or roof side rails
from which the SRS side airbags or
SRS curtain shield ai rbags deploy even
if the child is seated in the child
restraint system. It is dangerous if the
SRS side airbags and curtain shield air-
bags inflate, and the impact could
cause death or serious injury to the
child.
●When a booster seat is installed,
always ensure that th e shoulder belt is
positioned 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.
●Use child restraint system suitable to
the age and size of the child and install
it to the rear seat.
●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.
●Adjust the front passe nger seat so that
it does not interfere with the child
restraint system.
