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.

When installing a child restraint
system to a 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 passenger seat as follows
and install the child restraint system.
 Raise the seatback as much as pos-
sible
 Move the seat to the rearmost posi-
tion
 Raise the seat to the upper most
position
 If the head restraint interferes with
the child restraint system installa-
tion and the head restraint can be
removed, remove the head restraintWhen using a child restraint sys-
tem on a passenger seat WARNING■
When installing a child restraint sys-
tem
Observe the following when installing
child restraint system to the front passen-
ger seat if it is unavoidable. The front pas-
senger SRS air bag inflates with
considerable speed and force that if not
observed may lead to death or serious
injury to the child. ●
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-fac ing 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. ●
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.

al_USA_OM78212U 1
For safety and security ( → P.369) go off. If th ere is only a small
amount of fuel, the hybrid system may not
be able to start. (The standard amount of
fuel is about 2.7 gal. [10.1 L, 2.2 Imp.gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.) ■
Electromagnetic waves●
High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
shielding, and ther efore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.●
Your vehicle may cause sound interfer-
ence in some third party-produced radio
parts.■
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a
limited service life. The lifespan of the
hybrid battery (traction battery) can
change in accordance with driving style and
driving conditions.
WARNING■
High voltage precautions
This vehicle has high voltage DC and AC
systems as well as a 12-volt system. DC
and AC high voltage is very dangerous
and can cause severe burns and electric
shock that may result in death or serious
injury. ●
Never touch, disassemble, remove or
replace the high voltage parts, cables
or their connectors.
●
The hybrid system will become hot
after starting as the system uses high
voltage. Be careful of both the high
voltage and the high temperature, and
always obey the warning labels
attached to the vehicle. ●
Never try to open the service plug
access hole located underneath the
rear seats. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.
■
Road accident cautions
Observe the following precautions to
reduce the risk of de ath or serious injury:●
Pull your vehicle off the road, shift the
shift lever to P, apply the parking brake,
and turn the hybrid system off. ●
Do not touch the high voltage parts,
cables and connectors. ●
If electric wires ar e exposed inside or
outside your vehicle, an electric shock
may occur. Never touch exposed elec-
tric wires. ●
If a fluid leak occurs, do not touch the
fluid as it may be st rong alkaline elec-
trolyte from the hybrid battery (trac-
tion battery). If it comes into contact
with your skin or eyes, wash it off
immediately with a large amount of
water or, if possible, boric acid solu-
tion. Seek immediate medical atten-
tion.
●
If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Never use a fire extinguisher that is not
meant for electric fires. Using even a
small amount of water may be danger-
ous.

66 1-2. Hybrid system
LEXUS NX300h Owners Manu-
al_USA_OM78212U The cooling air intake and discharge
vents for the hybrid battery (traction
battery) are located under the rear
seats and between the rear seats and
deck board, respectively. If the air
intake vents are blocked, it could lead
to a reduction in hybrid battery (trac-
tion battery) output. The hybrid battery (traction battery) out-
put will not be reduced, even if the space
between the upper part of the air dis-
charge vents on the back of the rear seat
and deck board is blocked with luggage,
etc.WARNING●
If your vehicle needs to be towed, do
so with four wheels raised. If the
wheels connected to the electric
motor (traction motor) are on the
ground when towing, the motor may
continue to generate electricity. This
may cause a fire. ( → P.360)●
Carefully inspect the ground under the
vehicle. If you find that liquid has
leaked onto the ground, the fuel sys-
tem may have been damaged. Leave
the vehicle as soon as possible.■
Hybrid battery (traction battery)●
Never resell, hand over or modify the
hybrid battery. To prevent accidents,
hybrid batteries that have been
removed from a disposed vehicle are
collected through Lexus dealers. Do
not dispose of the battery yourself.
Unless the battery is properly collected,
the following may occur, resulting in
death or serious injury:
• The hybrid battery may be illegally dis-
posed of or dumped, and it is hazard-
ous to the environment or someone
may touch a high voltage part, result-
ing in an electric shock.
• The hybrid battery is intended to be
used exclusively with your hybrid vehi-
cle. If the hybrid battery is used outside
of your vehicle or modified in any way,
accidents such as electric shock, heat
generation, smoke generation, an
explosion and electrolyte leakage may
occur.
When reselling or handing over your
vehicle, the possibility of an accident is
extremely high because the person
receiving the vehicle may not be aware
of these dangers. ●
If your vehicle is disposed of without
the hybrid battery having been
removed, there is a danger of serious
electric shock if hi gh voltage parts,
cables and their connectors are
touched. In the event that your vehicle
must be disposed of, the hybrid battery
must be disposed of by your Lexus
dealer or a qualified service shop. If
the hybrid battery is not disposed of
properly, it may cause electric shock
that can result in death or serious
injury.
