62 1-2. Hybrid system
LEXUS NX300h Owners Manu-
al_USA_OM78212U Also, even in heavy traffic conditions,
drive the vehicle in D or S. *
: When the hybrid battery (traction bat-
tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop. ( → P.62)■
During normal driving
The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery
(traction battery) as necessary. ■
When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of the
hybrid battery (traction battery) is
added to that of the gasoline engine via
the electric motor (traction motor). ■
When braking (regenerative brak-
ing)
The wheels operate the electric motor
(traction motor) as a power generator,
and the hybrid battery (traction bat-
tery) is charged. ■
Regenerative braking
In the following situations, kinetic energy is
converted to electric energy and decelera-
tion force can be obta ined in conjunction
with the recharging of the hybrid battery
(traction battery).
●
The accelerator pedal is released while
driving with the shift lever in D or S.
●
The brake pedal is depressed while driv-
ing with the shift lever in D or S.
■
EV indicator
The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or th e gasoline engine is
stopped. ■
Conditions in which the gasoline engine
may not stop
The gasoline engine starts and stops auto-
matically. However, it may not stop auto-
matically in the following conditions *
:●
During gasoline engine warm-up ●
During hybrid battery (traction battery)
charging ●
When the temperature of the hybrid bat-
tery (traction battery) is high or low ●
When the heater is switched on *
: Depending on the circumstances, the
gasoline engine may also not stop auto-
matically in other situations. ■
Charging the hybrid battery (traction
battery)
As the gasoline engine charges the hybrid
battery (traction battery), the battery does
not need to be charged from an outside
source. However, if the vehicle is left parked
for a long time the hybrid battery (traction
battery) will slowly discharge. For this rea-
son, be sure to drive the vehicle at least
once every few months for at least 30 min-
utes or 10 miles (16 km ). If the hybrid bat-
tery (traction battery) becomes fully
discharged and you are unable to start the
hybrid system, contact your Lexus dealer.
■
Charging the 12-volt battery
→ P.392
■
After the 12-volt battery has discharged
or when the terminal has been removed
and installed during exchange, etc.
The gasoline engine may not stop even if
the vehicle is being driven by the hybrid bat-
tery (traction battery). If this continues for a
few days, contact your Lexus dealer.

256 4-6. Driving tips
LEXUS NX300h Owners Manu-
al_USA_OM78212U Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently apply the brakes. A greater
amount of electrical energy can be
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season. Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.Highway driving

318 6-1. Maintenance and care
LEXUS NX300h Owners Manu-
al_USA_OM78212U  Remove dirt and dust using a vac-
uum cleaner.
 Wipe off any excess dirt and dust
with a soft cloth dampened with
diluted detergent. Use a diluted water solution of approxi-
mately 5% neutral wool detergent.
 Wring out any excess water from
the cloth and thoroughly wipe off all
remaining traces of detergent.
 Wipe the surface with a dry, soft
cloth to remove any remaining
moisture. Allow the leather to dry in
a shaded and ventilated area. ■
Caring for leather areas
Lexus recommends cleani ng the interior of
the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
 Remove dirt and dust using a vac-
uum cleaner.
 Wipe it off with a soft cloth damp-
ened with neutral detergent diluted
to approximately 1%.
 Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent and
water.NOTICE■
Preventing damage to leather sur-
faces
Observe the following precautions to
avoid damage to and deterioration of
leather surfaces: ●
Remove any dust or dirt from leather
surfaces immediately.●
Do not expose the vehicle to direct
sunlight for extended periods of time.
Park the vehicle in the shade, espe-
cially during summer.●
Do not place items made of vinyl, plas-
tic, or containing wax on the uphol-
stery, as they may stick to the leather
surface if the vehicle interior heats up
significantly.■
Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system
may be damaged if water comes into
contact with electrical components such
as the audio system above or under the
floor of the vehicle. Water may also
cause the body to rust. ■
When cleaning the inside of the wind-
shield
(vehicles with Lexus Safety System+)
Do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
( → P.198)
■
Cleaning the inside of the rear win-
dow●
Do not use glass cleaner to clean the
rear window, as this may cause dam-
age to the rear window defogger
heater wires or antenna. Use a cloth
dampened with lukewarm water to
gently wipe the window clean. Wipe
the window in strokes running parallel
to the heater wires or antenna.
●
Be careful not to scratch or damage
the heater wires or antenna. ■
Cleaning the front side windows
Do not use any compound or abrasive
product (e.g., glass cleaner, detergent,
wax) to clean the windows. It may dam-
age the coating.
