■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but- tons on the electronic key while inside the ai rcraft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally. Pressing a button may cause the electronic key to emit radio waves that could interferewith the operation of the aircraft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and a half.)
●If the battery becomes low, an alarm will so und in the cabin when the hybrid system is stopped. ( P. 559)
●As the electronic key always receives radio waves, the battery will become depleted
even if the electronic key is not used. The following symptoms indicate that the elec- tronic key battery may be depleted. Replace the battery when necessary. ( P. 511)
• The smart entry & start system or the wireless remote control does not operate.
• The detection area becomes smaller. • The LED indicator on the key surface does not turn on.

■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 cu rrent air conditioning settings will automati-
cally 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 qu alified 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 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.
■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 ou tlets 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 entering the vehicle interior . During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automati cally switch depending on the tempera-
ture setting or the inside temperature.
■Automatic mode for air intake control
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.
■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 following operations:
●Adjust the fan speed
●Turn off Eco drive mode
