■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 airc raft cabin. If you are carrying an electronic
key in your bag etc., ensure that the button s are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere with 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. 606)
●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. 549)
• The smart entry & start system or the wi reless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the ke y surface does not turn on.
●To avoid serious deterioration, do not leave the electronic key within 1 m (3 ft.) of the
following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, co rdless phones and battery chargers • Recharging cellular phon es or cordless phones
•Table lamps
• Induction cookers

■Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask any autho- rized Lexus retailer or Lexus authorized re pairer, or any reliable repairer for details.
■If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.

■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 ke y’s registered air conditioning settings.
●When the power switch is turned off, the current 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
retailer or Lexus authorized re pairer, or any reliable repairer.
*: The doors that can recall the driving position memory are changed at the same time.
■Using automatic mode
Fan speed is adjusted automatically accordin g 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 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 ai r mode. This is effective in preventing out- side air from entering the vehicle interi or. 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.
■Operation of the air conditioni ng 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
