lean forward too quickly. A slow, easy
motion will allow the belt to extend so that
you can move around fully.

For safety and security WARNING■
SRS airbag precautions
Observe the following precautions
regarding the SRS airbags.
Failure to do so may cause death or seri-
ous injury. ●
The driver and all passengers in the
vehicle must wear their seat belts
properly.
The SRS airbags are supplemental
devices to be used with the seat belts. ●
The SRS driver airbag deploys with
considerable force, and can cause
death or serious injury especially if the
driver is very close to the airbag. The
National Highway Traffic Safety
Administration (NHTSA) advises:
Since the risk zone for the driver’s air-
bag is the first 2 - 3 in. (50 - 75 mm) of
inflation, placing yourself 10 in. (250
mm) from your driver airbag provides
you with a clear margin of safety. This
distance is measured from the center
of the steering wheel to your breast-
bone. If you sit less than 10 in. (250
mm) away now, you can change your
driving position in several ways:
• Move your seat to the rear as far as
you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many
drivers can achieve the 10 in. (250
mm) distance, even with the driver seat
all the way forward, simply by reclining
the back of the seat somewhat. If
reclining the back of your seat makes it
hard to see the road, raise yourself by
using a firm, non-slippery cushion, or
raise the seat if your vehicle has that
feature.
• If your steering wheel is adjustable, tilt
it downward. This points the airbag
toward your chest instead of your head
and neck.
The seat should be adjusted as recom-
mended by NHTSA above, while still
maintaining control of the foot pedals,
steering wheel, and your view of the
instrument panel controls.

38 1-1. For safe use
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.

cle. 
Booster type 
High back type
3 Sit the child in the child restraint
system. Fit the seat belt to the child
restraint system according to the
manufacturer’s in structions and
insert the plate into the buckle.
Make sure that the belt is not
twisted.Check that the shoulder belt is correctly
positioned over the child’s shoulder and
that the lap belt is as low as possible. ( → P.27)
■
Removing a child restraint system
installed with a seat belt
Press the buckle release button and
fully retract the seat belt. When releasing the buckle, the child
restraint system may sp ring up due to the
rebound of the seat cushion. Release the
buckle while holding down the child
restraint system.
Since the seat belt auto matically reels itself,
slowly return it to the stowing position.

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.

the vehicle inspected by your Lexus dealer
immediately. ■
Battery-saving function
The battery-saving fu nction will be acti-
vated in order to prevent the electronic key
battery and the 12-volt battery from being
discharged while the vehicle is not in opera-
tion for a long time. ●
In the following situations, the smart
access system with pu sh-button start may
take some time to unlock the doors.
• The electronic key has been left in an
area of approximately 6 ft. (2 m) of the
outside of the vehicle for 10 minutes or
longer.
• The smart access system with push-but-
ton start has not been used for 5 days or
