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.

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.

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.
