For safety and security
vehicle with at least enough gasoline to
make the low fuel level warning light
( P.393) 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 are 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.

721-4. Hybrid system
LEXUS NX300h Owners Manual_USA_M78578_en
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.383)
●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.
NOTICE
■Hybrid battery (traction battery)
Do not carry large amounts of water
such as water cooler bottles in the vehi-
cle. If water spills onto the hybrid battery
(traction battery), the battery may be
damaged.
Have the vehicle inspected by your
Lexus dealer.

For safety and security
Air intake vents
Air discharge vents When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks the
high voltage current and stops the fuel
pump to minimize the risk of electrocu-
tion and fuel leakage. If the emergency
shut off system activates, your vehicle
will not restart. To restart the hybrid
system, contact your Lexus dealer.
A message is automatically displayed
when a malfunction occurs in the
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.
NOTICE
■Hybrid battery (traction battery) air
intake and discharge vents
●Do not place objects
that will block the
air intake vents. The hybrid battery
(traction battery) may have a reduc-
tion in hybrid battery (traction battery)
output as well as be damaged.
●Clean the air intake and discharge
vents regularly to prevent the hybrid
battery (traction battery) from over-
heating.
●Do not get water or foreign materials
in either the air intake and discharge
vents as this may cause a short circuit
and damage the hybrid battery (trac-
tion battery).

B
●If “Maintenance required for Traction
battery cooling parts See owner’s
manual” is shown on the multi-informa-
tion display, clean the air intake vents
(  P.337). If the message is still dis-
played after cleaning the air intake
vents, have the vehicle inspected by
your Lexus dealer.
●A filter is installed to the air intake vent.
When the filter re mains noticeably
dirty even after cleaning the air intake
vent, filter cleaning or replacement is
recommended. For information
regarding filter cleaning or replace-
ment, contact your Lexus dealer.

WARNING
■If a safety system warning light does
not come on
Should a safety system light such as the
ABS and SRS airbag warning light not
come on when you start the hybrid sys-
tem, this could mean that these systems
are not available to help protect you in an
accident, which could result in death or
serious injury. Have the vehicle inspected
by your Lexus dealer immediately if this
occurs.
