■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

■When the outside temperature falls to nearly 32F (0 C)
The dehumidification function may not operate even when is pressed or “A/C” is
selected.
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditio ning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into and accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior to turning the vehicle off.
• The start timing of the blower may be dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.
■Air conditioning filter

■Customization
Settings (e.g. A/C Auto switch operation) can be changed.
(Customizable features P. 5 5 8 )
CAUTION
■To prevent the windshield from fogging up
●Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can cause
the outer surface of the windshield to fog up, blocking your vision.
■To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on.
●Do not touch the glass at lower part of the wi ndshield or to the side of the front pillars
when the windshield wiper de-icer is on.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine is
stopped.
●Do not place anything on the instrument
panel which may cover th e air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.

light comes on for 2 seconds then turns off. Afterward, the green indicator light
comes on, indicating that the service is active.

■Automatic Collis ion Notification
In case of either airbag deployment or severe rear-end collision, the system is
designed to automatically call the response center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicle occu-
pants to assess the level of emergency. If the occupants are unable to commu-
nicate, the agent automatically treats the call as an emergency, contacts the
nearest emergency services provider to describe the situation, and requests
that assistance be se nt to the location.
