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

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. ■

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 .
