WARNING
. The air conditioner cooling function
operates only when the engine is run-
ning.
. Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. On hot, sunny
days, temperatures in a closed vehicle
could quickly become high enough to
cause severe or possibly fatal injuries to
people or animals.
. Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
Start the engine and operate the automatic
climate control system.
When the “STATUS”button is pushed, the
automatic climate control status screen

VENTILATORS AUTOMATIC CLIMATE CONTROL

SAA2734
Ion control:
This unit generates highly concentrated
Plasmacluster
®ions into the air blown
from the ventilators and reduces odors
absorbed into the interior trim.
The high-density Plasmacluster
®ions gen-
erated in the air conditioner’s air stream
not only suppress airborne bacteria and
reduce the adherence of odors to the
interior trim, but also have a proven skin
moisture preserving effect.
When the air conditioner is turned on, the
system generates Plasmacluster
®ions
automatically. The amount of Plasmacluster
®ions in-
creases according to the amount of air
flow. When the air flow is high, “
”is
displayed on the screen and when the air
flow is low, the indication in the screen
changes to “
”.

poration.
Outside odor and exhaust gas detection
sensor:
This vehicle is equipped with an outside
odor and exhaust gas detection sensor.
When the automatic intake air control is
ON, the sensor detects odors and exhaust
gases, and then the system automatically
changes from the outside air circulation
mode to the recirculation mode.
When the intake air control button is
pushed under the following conditions,
the indicator light on the “
”side will
illuminate and the outside odor and
exhaust gas detection sensor will turn on.
. The air flow control is not in the front
defroster mode (the indicator light on
the “
”front defroster button is
turned off). .
The outside temperature is about 328F
(08C) or more.
. The outside odor and exhaust gas
detection sensor detects industrial
odors such as pulp or chemicals, and
exhaust gases such as gasoline or
diesel.
When the automatic intake air control is
ON, for the first 5 minutes, the recircula-
tion mode is selected to prevent dust, dirt
and pollen from entering the vehicle and
cleans the air inside of the vehicle with
positive and negative ions that are emitted
from the ventilator.
After the 5 minutes, the sensor detects
outside odors and exhaust gases and
automatically alternates between the re-
circulation mode and outside air circula-
tion mode.
OPERATING TIPS
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 nor-
mally from the foot outlets.

IN-CABIN MICROFILTER
To make sure that the air conditioner
heats, defogs and ventilates efficiently,
replace the filter according the specified
maintenance intervals listed in the INFINITI
Service and Maintenance Guide. To replace
the filter, contact 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. A natural grape seed polyphe-
nol filter (if so equipped) collects and
neutralizes dirt, pollen, dust, etc.
SERVICING CLIMATE CONTROL
The climate control system in your INFINITI
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 your
INFINITI air conditioner. Using improper
refrigerants or lubricants will cause severe
damage to your climate control system.
(See “Capacities and recommended fuel/
lubricants” (P.9-2) for climate control sys-
tem refrigerant and lubricant recommenda-
tions.)
Your INFINITI retailer will be able to service
your environmentally friendly climate con-
trol 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.
AUDIO OPERATION PRECAUTIONS
Radio
Push the ignition switch to the ACC or ON
position and push the radio band select
button to turn on the radio. If you listen to
the radio with the engine not running, the
ignition switch should be pushed to the
ACC position.
Radio reception is affected by station
signal strength, distance from radio trans-
mitter, buildings, bridges, mountains and
other external influences. Intermittent
changes in reception quality normally are
caused by these external influences.
Using a cellular phone in or near the
vehicle may influence radio reception
quality.
Radio reception:
Your INFINITI radio system is equipped with
state-of-the-art electronic circuits to en-
hance radio reception. These circuits are
designed to extend reception range, and to
enhance the quality of that reception.
However there are some general character-
istics of both FM and AM radio signals that
can affect radio reception quality in a
moving vehicle, even when the finest
