■Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning system is controlled as follows to priori-
tize 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
• Turn off Eco drive mode
■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
ambient conditions. As a result, the following may occur:
●Immediately after the “AUTO” switch is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting
“A/C” on will dehumidify the air from the outlets and defog the windshield effec-
tively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicle interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.

■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 system. This may then cause odor to be emitted
from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning 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 immedi-
ately after the air conditioning system is started in automatic mode.
■nanoe *1
Your vehicle incorporates a nanoe device, which is considered a biocidal product.
The nanoe  device generates charged water particles from the ambient air. These
particles purify the air in the cabin by suppressing bacteria.
The nanoe  device is considered a biocidal product in the EU according to the
interpretation of Regulation (EU) No 528/2012.
Active substances: Charged water particles (nano) containing hydroxyl radicals,
generated from ambient air
nanoe  helps to provide purified air by emitting electrically charged water particles
through the front center vent on the driver’s side*2.
●When the fan is turned on and “nanoe” on the option control screen is selected, the
nanoe  is activated.
●When the fan is operated in the following conditions, system performance will be
maximized. If the following conditions are not met, the nanoe  may not operate at
full capacity.
• The , or air outlets are being used.
• The front center vent on driver’s side is open.
●When nanoe  is generated, a small amount of ozone is emitted and may be faintly
smelled in some situations. However, this is approximately the same as the amount
that already exists in nature, such as in forests, and it has no affect on the human
body.
●A slight noise may be heard during operation. This is not a malfunction.
*1:nanoe  and the nanoe mark are trademarks of Panasonic Corporation.
*2: According to temperature and humidity conditions, fan speed and direction of the
air flow, the nanoe  may not operate at full capacity.

Maintenance and care
LS600h/LS600hL_EE(OM50G20E)
Tire inflation pressure (P. 525)• Tire pressure gauge
• Compressed air source
Washer fluid ( P. 501)
• Water or washer fluid containing anti-
freeze (for winter use)
• Funnel (used only for adding water or
washer fluid)
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious
injury, observe the following precautions.
■When working on the engine compartment
●Make sure that the indicator on the power switch and the “READY” indicator are
both off.
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, power control unit, radiator, exhaust manifold,
etc. right after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flam-
mable.
●Take care because brake fluid can harm your hands or eyes and damage painted
surfaces. If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience disc omfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automatically
start to run if the air conditioning is on and/or the coolant temperature is high.
( P. 500)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.

■The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire inflation
pressure adjustment.
●If you have accidentally turned the power switch off during initialization, it is not
necessary to press the reset switch again as initialization will restart automatically
when the power switch has been turned to ON mode for the next time.
●If you accidentally press the reset switch when initialization is not necessary, adjust
the tire inflation pressure to the specified level when the tires are cold, and conduct
initialization again.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accordance with driv-
ing conditions. For this reason, the system may give a warning even if the tire pres-
sure does not reach a low enough level, or if the pressure is higher than the pressure
that was adjusted to when the system was initialized.
■When initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following cases, the
settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure settings are unsuccessful, have
the vehicle inspected by any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
●When operating the tire pressure warning reset switch, the tire pressure warning
light does not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warning light blinks
for 1 minute then stays on after driving for 20 minutes.
■Registering ID codes (except for Israel)
The ID codes of the tire pressure warning valve and transmitters for two sets of
wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with snow
tires, if the ID codes for the wheels of both normal tires and snow tires are registered
beforehand.
For information about changing ID codes, ask any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
