AUTOMATIC CLIMATE CON-
TROL SYSTEM
AUTOMATIC OPERATION
Cooling and/or dehumidified heat-
ing (AUTO)
This mode can be used all year round. The
system works automatically to control the
inside temperature, air flow distribution and
fan speed after the preferred temperature is
set manually.
1. Push . (The indicator on the
button will illuminate and “AUTO” will
be displayed on the CLIMATE screen.)
2. Push <
>and <>on the driver’s side
to set the desired temperature.
. The temperature of the passenger com-
partment will be maintained automati-
cally. Air flow distribution and fan speed
will also be controlled automatically.
. When the DUAL mode is turned on, you
can individually set the driver’s and front
passenger side temperatures by pushing
<
>and <>on the corresponding
side. To turn on the DUAL mode, touch
[DUAL] on the lower display (“AUTO”
will be displayed on the lower display). To disable the front passenger side
temperature control, touch [DUAL] and
turn off the DUAL mode.
INFO:
A visible mist may be seen coming from the
ventilators in hot, humid conditions as the air
is cooled rapidly. This does not indicate a
malfunction.
Heating (A/C off)
The air conditioner does not activate in this
mode. When you need to heat only, use this
mode.
1. Touch [A/C] on the lower display. The A/C indicator will turn off.
2. Push <
>and <>on the driver’s side
to set the desired temperature.
INFO:
. When set the AUTO mode, the tempera-
ture of the passenger compartment will
be maintained automatically. Air flow
distribution and fan speed are also
controlled automatically.
. Do not set the temperature lower than
the outside air temperature. Otherwise,

the system may not work properly.
. This mode is not recommended if the
windows fog up.
Dehumidified defrosting or defog-
ging
1. Push <>. The indicator light on the
button will illuminate.
2. Push <
>and <>on the driver’s side
to set the desired temperature.
INFO:
. To quickly remove ice from the outside of
the windows, set the fan speed to the
maximum.
. As soon as possible after the windshield
is clean, push to return to the
auto mode.
. When <
>is pushed, the air conditioner
will automatically be turned on at out-
side temperatures above 23°F (−5°C) to
defog the windshield, and the air recir-
culate mode will automatically be turned
off.
Outside air is drawn into the passenger
compartment to improve the defogging performance.
ADVANCED CLIMATE CONTROL
SYSTEM (if so equipped)
The Advanced Climate Control System
keeps the air inside of the vehicle clean,
using the automatic air circulation control
with the exhaust gas/outside odor detecting
sensor and with ion control.
[Auto Recirc]:
Touch to turn on the automatic air
recirculation mode.
Plasmacluster® icon:
Indicates the Plasmacluster® ion emis-
sion status.
Automatic air recirculation control with the
exhaust gas/outside odor detection sensor:
The Advanced Climate Control system
comes with an exhaust gas detection/out-
side odor sensor. When the automatic air
circulation control is activated, the sensor
detects odors outside the vehicle such as
pulp or chemicals, and exhaust gas such as
gasoline or diesel. When such odors or gases
are detected, the display and the system
automatically change from the fresh air
mode to the recirculation mode.
When the automatic air circulation control
mode is on, for the first 5 minutes, the air
recirculation mode is selected to prevent
dust, dirt and pollen from entering the
vehicle and to clean the air inside of the
vehicle.
After 5 minutes, the sensor detects exhaust
gas and automatically alternates between
the air recirculation mode and the fresh air
mode.INFO:
The automatic air recirculation mode can be
activated under the following conditions. . The air flow control is not in the
windshield defrosting mode (the indica-

tor light on<>is turned off).
. The outside temperature is approxi-
mately 32 °F (0 °C) or above.
Ion control:
The Advanced Climate Control system unit
generates highly concentrated Plasmaclus-
ter® ions into the air blown from the
ventilators to reduce odor absorbed into
the interior trim and to suppress airborne
bacteria. The high-density Plasmacluster®
ions also have a proven skin moisture
preserving effect.
The Plasmacluster® icon on the CLIMATE
screen indicates the status of the Plas-
macluster® ion emission from the system
and changes with the amount of the air flow.OPERATING TIPS
. The sensorsandon the instrument
panel helps maintain a constant tem-
perature. Do not put anything on or
around these sensors.
. When the engine coolant temperature
and outside air temperature are low, the air flow from the foot outlets may not
operate. This is not a malfunction. After
the coolant temperature warms up, air
will flow normally from the foot outlets.
. A visible mist may be seen coming from
the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
IN-CABIN MICROFILTER
With Advanced Climate Control system:
The Climate Control system is equipped with
a natural grape seed polyphenol filter that
collects and neutralizes dirt, pollen, dust,
allergens (such as pollen, tick shells), etc. To
make sure that the air conditioner heats,
defogs and ventilates efficiently, replace the
filter in accordance with the maintenance
schedule in the vehicle Owner’s Manual. To
replace the filter, it is recommended you visit
an INFINITI retailer.
The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air
conditioner.

Without Advanced Climate Control system:
The Climate Control system is equipped with
an in-cabin microfilter that collects dirt,
pollen, dust, etc. To make sure that the air
conditioner heats, defogs and ventilates
efficiently, replace the filter in accordance
with the maintenance schedule in the vehicle
Owner’s Manual. To replace the filter, it is
recommended you visit an INFINITI retailer.The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air
conditioner.
SERVICING HEATER AND AIR
CONDITIONER
The heating and air conditioning system in
your vehicle is charged with a refrigerant
designed with the environment in mind. This
refrigerant will not harm the earth’s ozone
layer. However, special charging equipment
and lubricant are required when servicing the
air conditioner. Using improper refrigerants
or lubricants will cause severe damage to
your Climate Control system. Refer to the
vehicle Owner’s Manual for heating and air
conditioning system refrigerant and lubri-
cant recommendations.
It is recommended you visit an INFINITI retailer to service your environmentally
friendly heater and air conditioning system.
WARNING
The system contains refrigerant under
high pressure. To avoid personal injury,
any air conditioner service should be done
only by an experienced technician with
the proper equipment.
REAR WINDOW AND OUTSIDE
MIRROR DEFROSTER
CAUTION
When cleaning the inner side of the rear
window, be careful not to scratch or
damage the rear window defroster.
To defog/defrost the rear window glass and
outside mirrors, start the engine and push
<
>. The indicator light on the button will
illuminate. Push the button again to turn off
the defroster.
The defroster will automatically turn off in
approximately 15 minutes.
If the engine is started using the remote start
function (if so equipped) when the outside
air temperature, the interior temperature
and the engine coolant temperature are
low, the rear window glass and outside
mirror defroster may turn on automatically.
For additional information about the remote
engine start function, refer to the vehicle
Owner’s Manual.
