■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic key and turning the engine switch switch> to IGNITION ON mode will recall that key’s registered air conditioning settings.
●When the engine switch is turned off, the current air conditioning
settings will automatically be registered to the electronic key that was used to unlock the vehicle.
●The system may not operate correctly if more than one electronic key is in the
vicinity or if the smart entry & start system is used to unlock the passenger door.
●The doors that can recall the air condi-
tioning setting* when unlocked using the
smart entry & start system can be changed. For details, contact any autho-rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.*: 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 drive mode
In Eco drive 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
●Turn off Eco drive mode ( P.242)
■When the outside temperature falls to
nearly 0°C (32°F)
The dehumidification function may not
operate even when “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.
●When parking, the system automatically switches to fresh air intake mode to encourage better air circulation through-
out the vehicle, helping to reduce odors that occur when starting the vehicle.

WARNING
■To prevent the windshield from fog- ging up
Do not use the 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.
■When the outside rear view mirror defoggers are operating
Do not touch the outside rear view mir- ror surfaces, as they can become very hot and burn you.

■Pollen removal mode
Outside air mode switches to
(recirculated air) mode. Pollen is removed
from the air and the air flows to the upper
part of the body.
Usually the system will automatically turn
off after approximately 1 to 3 minutes.
In order to prevent the windshield from fog-
ging up when the outside air is cold, the
dehumidification function may operate or
the outside/recirculated air mode may not
switch to (recirculated air) mode.
Pollen is filtered even if the pollen removal
mode is turned off.
■nanoe™ system
This vehicle incorporates a biocidal prod-
uct.
Ionised air generated by a device incorpo-
rated in the vehicle purifies the air in the
cabin by suppressing bacteria.
Active substance: Free radicals generated
in situ from ambient air or water
nanoe™ helps to provide purified air by
emitting electrically charged water parti-
cles through the front center vent on the
driver’s side
*.
●When the fan is turned on and nanoe™
on the option control screen is selected,
the nanoe™ system is activated.
●When the fan is operated in the following
conditions, system performance will be
maximized. If the following conditions are
not met, performance will be limited.
• 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. How-
ever, 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 oper-
ation. This is not a malfunction.
*: According to temperature and humidity
conditions, fan speed and direction of the
air flow, the nanoe™ system may not
operate at full capacity.
1 Press the automatic mode switch or
select “AUTO” on the sub function

WARNING
■When the Emergency Call may not be made
●Any of the followings may occur. In such cases, report to the Public Safety
Answering Point (PSAP) by other means such as nearby public phones.
• It may sometimes be difficult to con- nect to the Public Safety Answering Point (PSAP) even in the reception
area of the cellular phone due to the reception level, or if the line is busy.In such cases, you may not be able to
connect to the Public Safety Answer- ing Point (PSAP) and thus will not be able to make emergency calls and
report to the emergency departments even though the system tries to con-nect to the Public Safety Answering
Point (PSAP).
• When the vehicle is out of the cellular
phone service area, the Emergency Call cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator lights, microphone, speaker, DCM,
antenna, or any wires connecting the equipment.) has an abnormality, is damaged or broken, the Emergency
Call cannot be made.
• During the Emergency Call, the sys-
tem makes repeated attempts to con- nect to the Public Safety Answering Point (PSAP). However, if it cannot
connect to the Public Safety Answer- ing Point (PSAP) due to poor radio wave reception, the system may not be
able to connect to the cellular network and the call may finish without con-necting. The red indicator light will
blink for approximately 30 seconds to indicate this disconnection.
• This device may not function if a shock is applied to it.
