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 conditioning setting* when unlocked using the smart
access system with push-button start can be changed. For details, contact your Lexus
dealer.
*: The doors that can recall the driving posi tion memory are change d 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 is pressed or “AUTO” is selected. ■
Using the voice command system
Air conditioning system can be operated using voic e commands. For details, refer to the
“NAVIGATION AND MULTIMEDIA SYSTEM OWNER’S MANUAL”. ■
Fogging up of the windows
The windows will easily fog up when the hu midity in the vehicle is high. Turning
(“A/C”) on will dehumidify the air from the outlets and defog the wi ndshield 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 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 automa tically. This may also reduce fuel consump-
tion. ●
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 .

Automatic mode for air intake control
In automatic mode, the system detects ex haust gas and other pollutants and auto-
matically 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. ■
Operation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to prioritize fuel
efficiency: ●
Engine speed and compressor operation controlled to restrict heating/cooling capac-
ity ●
Fan speed restricted when automatic mode is selected
To improve air conditioning performanc e, perform the foll owing operations:●
Adjust the fan speed ●
Turn off Eco drive mode ■
When the outside temperature falls to nearly 32  F (0  C)
The dehumidification function may not oper ate even when 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 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.■

caused in a car wash etc. ●
The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant. ●
The restoration time differs depending on the depth of the scratch and outside tem-
perature.
The restoration time may become shorter when the coating is warmed by applying
warm water. ●
Deep scratches caused by keys, coins, etc. cannot be restored. ●
Do not use wax that contains abrasives.
* : CFRP parts (if equipped) do not have a self-restoring coat.Cleaning and protect ing the vehicle exteriorPerform the following to protect the ve hicle and maintain it in prime condi-
tion:
