Interior features
IS300h_EE(OM53B95E)
Registering air conditioning settings to electronic keys (vehicles with driving
position memory)
Unlocking the vehicle using an electronic key and turning the power switch to
ON mode will recall that key’s registered air conditioning settings.
When the power 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 a passenger door.
The doors that can recall the air conditioning setting when unlocked using the
smart entry & start system can be changed.* For details, contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
*: The doors that can recall the driving position memory are changed at the same
time.
Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until warm 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 humidity in the vehicle is high. Turning
(“A/C”) on will dehumidify the air from the outlets and defog the wind-
shield 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/
recirculated air mode button to the recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling opera-
tion, setting the recirculated air mode will also cool the vehicle interior effec-
tively.
Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.
Operation of the air conditioning system in Eco drive mode
In 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
