Bluetooth
® system.
■Caution regarding interference with electronic devices
●Your audio unit is fitted with Bluetooth® antennas. People with implantable cardiac
pacemakers, cardiac resynchronization ther apy-pacemakers or implantable cardio-
verter defibrillators should maintain a re asonable distance between themselves and
the Bluetooth
® antennas. The radio waves may affect the operation of such devices.
●Before using Bluetooth® devices, users of any electrical medical device other than
implantable cardiac pacemakers, cardiac resynchronization therapy-pacemakers or
implantable cardioverter defibrillators shou ld consult the manufacturer of the device
for information about its operation under the influence of radio waves. Radio waves
could have unexpected effects on th e operation of such medical devices.

3746-1. Using the air conditioning system
IS350/300/200t_U (OM53D18U)
■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 warm or cool air is ready to flow immediately
after is pressed or “AUTO” is selected.
■Using the voice command system (veh icles with a navigation system)
Air conditioning system can be operated usin g voice commands. For details, refer to the
“NAVIGATION SYSTEM OWNER’S MANUAL”.
■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 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 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 conditioning po wer 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 .
■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 performance, perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode
