When using Eco mode, the torque cor-
responding to the accelerator pedal
depression amount can be generated
more smoothly than it is in normal con-
ditions. In addition, the operation of the
air conditioning system (heating/cool-
ing) will be minimized, improving the
fuel economy. ( P.269)
The Eco-friendly driving is possible by
keeping the indicator needle of Hybrid
System Indicator within Eco area.
(  P.87)
Shift the shift lever to D when stopped
at a traffic light, or driving in heavy traf-
fic, etc. Shift the shift lever to P when
parking. When using the N, there is no
positive effect on fuel consumption. In
the N, the gasoline engine operates
but electricity cannot be generated.
Also, when using the air conditioning
system, etc., the hybrid battery (trac-
tion battery) power is consumed. 
Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.
Hybrid vehicle driving tips
For economical and ecological
driving, pay attention to the follow-
ing points:
Using Eco mode
Use of Hybrid System Indicator
Shift lever operation
Accelerator pedal/brake pedal
operation
When braking
Delays

2764-6. Driving tips
LEXUS NX300h Owners Manual_USA_M78530_en
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.

■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air
mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a
default mode when the power switch is
turned to ON mode.
●It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■Fogging up of the windows
●The windows will easily fog up when the
humidity in the vehicle is high. Pressing
“A/C” button or selecting “A/C” will
dehumidify the air from the outlets and
defog the windshield effectively.
●If you turn “A/C” off, the windows may
fog up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode tem-
porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the
outside air temperature is high.
●Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.
■Registering air conditioning settings to
electronic keys (vehicles with driving
position memory)
●Unlocking the vehicle using an electronic
key and turning the power switch to ON
mode will recall that key’s registered air
conditioning settings.
●When the power switch is turned off, the
current air conditioning settings will auto-
matically be registered to the electronic
key that was used to unlock the vehicle.
●The system may not operate correctly if
more than one electr onic key is in the
vicinity or if the smart access system with
push-button start is used to unlock a pas-
senger door.
●The doors that can recall the air condi-
tioning setting when unlocked using the
smart access system with push-button
start can be changed.
* For details, con-
tact your Lexus dealer.
*: The doors that can recall the driving posi-
tion memory are changed at the same
time.
■Operation of the air conditioning sys-
tem in Eco mode
●In the Eco mode, the air conditioning sys-
tem is controlled as follows to prioritize
fuel efficiency
• Engine speed and compressor operation
controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic
mode is selected
●To improve air conditioning performance,
perform the following operations
• Adjust the fan speed
• Adjust the temperature setting
• Turn off Eco mode
●Even when the driving mode is set to Eco
mode, the air conditioning eco mode can
be turned off by selecting the

■When the outside temperature is low
The dehumidification function may not
operate even when “A/C” is pressed or
“A/C” is selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
●During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning sys-
tem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occur-
ring:
• It is recommended that the air condition-
ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be
delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode.

WARNING
■To prevent the windshield from fog-
ging up
Do not use the front windshield defogger
switch during cool air operation in
extremely humid weather. The difference
between the temperature of the outside
air and that of the windshield can cause
the outer surface of the windshield to fog
up, blocking your vision.
■To prevent burns
●Do not touch the rear view mirror sur-
faces when the outside rear view mir-
ror defoggers are on.
●Vehicles with windshield wiper de-
icer: Do not touch the glass at lower
part of the windshield or to the side of
the front pillars when the windshield
wiper de-icer is on.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the air conditioning system
on longer than necessary when the
hybrid system is off.
