Registering air conditioning settings to elec tronic keys (vehicles with driving position
memory) ●
Unlocking the vehicle using an electronic ke y and turning the engine switch to IGNI-
TION ON mode will recall that key’s re gistered air conditioning settings.●
When the engine switch is tu rned off, the current air cond itioning settings will automat-
ically be registered to the electronic key that was used to unlock the vehicle. ●
The system may not operate correctly if more th an one electronic key is in the vicinity or
if the smart access system with push-button start is used to unlock a passenger door.●
The doors that can recall the air conditioni ng setting when unlocked using the smart
access system with push-b utton start can be changed.
* For details, contact your Lexus
dealer.
* : The doors that can recall the driving positi on memory are changed at the same time.■
Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until wa rm or cool air is ready to flow immediately
after the “AUTO” button is pressed or “AUTO” is selected. ■
How the system judges if a passenger is in the vehicle when in S-FLOW mode
In S-FLOW mode, the system judges if a passenger is in the vehicle as follows:
• Front passenger seat: A passeng er is judged to be in the front passenger seat when the
system detects an object on the front passe nger seat, fastening of the front passenger
seat belt, changing of the set temperature for the front passenger seat or the opening
and closing of the front passenger door. (However, when only opening and closing of
the front passenger door is detected, the sy stem will judge that a passenger is not in
the front passenger seat after the vehicl e speed reaches approximately 12 mph (20
km/h) or more.)
• Rear seats (automatic S-FLOW mode only): A passenger is judged to be in a rear seat
when the system detects the opening and closin g of a rear door or the operation of the
rear air conditioning system (RX350L).
If a passenger is judged to be in the vehicl e, the system will retain the judgement for a
certain amount of time after th e engine switch is turned off.■
Operation of automatic S-FLOW mode
When the system is operating in automati c S-FLOW mode, if the system detects the
opening and closing of a rear door or the op eration of the rear air conditioning system
(RX350L), S-FLOW mode will be disabled . To enable S-FLOW mode, select on
the option control screen. (I n this case, the system w ill operate in manual S-FLOW
mode.) ■
Changing from manual S-FLOW mode to automatic S-FLOW mode
Select on the option control screen to disable S-FLOW mode.
Turn the engine switch off.
Wait for 60 minutes or more and change the engine switch to IGNITION ON mode.■
Using the voice command system (vehicles with a navigation system)
Air conditioning system can be operated using voic e commands. For details, refer to the
“NAVIGATION SYSTEM OWNER’S MANUAL”. 1

RX350/RX350L_U ■
When the outside temperature exceeds 75  F (24  C) and the air conditioning system
is on ●
In order to reduce the air co nditioning 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 defaul t mode when the engine switch is turned to
IGNITION ON mode. ●
It is possible to switch to outside air mode at any time by pressing the outside/recircu-
lated air mode button. ■
Automatic mode for air intake control (if equipped)
In automatic mode, the system detects exhaust gas and other pollutants and automati-
cally switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function. ■
Fogging up of the windows ●
The windows will easily fog up when the humidity in the vehicle is high. 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 recirculated air mode is used. ■
Outside/recirculated air mode ●
When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from enteri ng the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively. ●
Outside/recirculated air mode may automa tically switch depending on the tempera-
ture setting or the inside temperature. ■
When the outside temperature is low
The dehumidification function may not operate even when “A/C” is selected. ■
Operation of the air conditioning system in Eco drive mode ●
In the Eco drive mode, the air conditioning sy stem 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 performanc e, perform the following operations:
• Adjust the fan speed
• Turn off Eco drive mode

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 accu-
mulate 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 dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.■

WARNING ■
To prevent the windshield from fogging up ●
Do not use during cool air operation in extremely humid weather. The differ-
ence 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 surfaces when the outside rear view mirror defog-
gers are on. ●
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. (if equipped)
NOTICE ■
To prevent battery discharge
Do not leave the air conditioni ng system on longer than necessary when the engine is
off. ●
Do not place anything on the instrument
panel which may cover th e air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.
