The advanced climate control system keeps the
air inside of the vehicle clean, using the ion
control and the automatic air intake control with
exhaust gas/outside odor detecting sensor.
Monitor, climate, audio, phone and voice recognition systems4-45

Ion control :
This unit generates highly concentrated Plas-
macluster ions into the air blown from the
ventilators and reduces odor absorbed into the
interior trim.
When the air conditioner is turned on, the
system generates Plasmacluster ions automati-
cally.
The amount of Plasmacluster ions increases
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 indica-
tion in the screen changes to “
”.
Exhaust gas/outside odor detecting sensor :
This vehicle is equipped with an exhaust
gas/outside odor detecting sensor. When the
automatic intake air control is ON, the sensor
detects odors and exhaust gas and the system
then 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
exhaust gas/outside odor detecting sensor will
turn on. ●
The air flow control is not in the front
defogger mode (the indicator light on the
“
” front defogger button is turned off).
● The outside temperature is about 32°F (0°C)
or more.
● The exhaust gas/outside odor detecting sen-
sor detects industrial odors such as pulp or
chemicals and exhaust gas such as gasoline
or diesel.
When the automatic intake air control is ON, for
the first 5 minutes, the recirculation mode is
selected to prevent dust, dirt and pollen from
entering the vehicle and cleans the air inside of
the vehicle with Plasumacluster ion that are
emitted from the ventilator.
After 5 minutes, the sensor detects outside odor
and exhaust gas and automatically alternates
between the recirculation mode and outside air
circulation mode.
OPERATING TIPS
When the engine coolant temperature and out-
side 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.

IN-CABIN MICROFILTER
Type A:
The climate control system is equipped with an
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure the air conditioner
heats, defogs, and ventilates efficiently, replace
the filter in accordance with the maintenance
schedule in the INFINITI Service and Mainte-
nance Guide. To replace the filter, contact an
INFINITI retailer. The filter should be replaced if air flow is ex-
tremely decreased or when windows fog up eas-
ily when operating heater or air conditioning
system.
Type B:
The climate control system is equipped with a
natural grape seed polyphenol filter which col-
lects and neutralizes dirt, pollen, dust, etc. To
make sure that the air conditioner heats, defogs
and ventilates efficiently, replace the filter in
accordance with the specified maintenance in-
tervals listed in the separate maintenance
booklet. To replace the filter, contact an INFINITI
retailer.
The filter should be replaced if the air flow de-
creases significantly or if windows fog up easily
when operating the heater or air conditioner.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” in the “9. Technical and consumer information” section for climate con-
trol system refrigerant and lubricant recommen-
dations.)
Your INFINITI retailer will be able to service your
environmentally friendly climate control sys-
tem.
WARNING
The system contains refrigerant under high
pressure. To avoid personal injury, any air con-
ditioner service should be done only by an ex-
perienced 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 transmitter, build-
ings, 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 enhance
radio reception. These circuits are designed to
extend reception range, and to enhance the
quality of that reception.However there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle,
even when the finest equipment is used. These
characteristics are completely normal in a given
reception area, and do not indicate any mal-
function in your INFINITI radio system.
Reception conditions will constantly change
because of vehicle movement. Buildings, ter-
rain, signal distance and interference from
other vehicles can work against ideal reception.
Described below are some of the factors that
can affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the
device in a different location may reduce or
eliminate the noise.
FM radio reception :
Range: FM range is normally limited to 25 to 30
miles (40 to 48 km), with monaural (single
channel) FM having slightly more range than
stereo FM. External influences may sometimes
interfere with FM station reception even if the
FM station is within 25 miles (40 km). The
strength of the FM signal is directly related to
the distance between the transmitter and re-
ceiver. FM signals follow a line-of-sight path,
exhibiting many of the same characteristics as
light. For example they will reflect off objects.
Fade and drift: As your vehicle moves away from
a station transmitter, the signals will tend to
fade and/or drift.
SAA0306
AUDIO SYSTEM
4-48Monitor, climate, audio, phone and voice recognition systems

Static and flutter: During signal interference
from buildings, large hills or due to antenna
position, usually in conjunction with increased
distance from the station transmitter, static or
flutter can be heard. This can be reduced by
lowering the treble setting to reduce the treble
response.
Multipath reception: Because of the reflective
characteristics of FM signals, direct and re-
flected signals reach the receiver at the same
time. The signals may cancel each other, result-
ing in momentary flutter or loss of sound.
AM radio reception :
AM signals, because of their low frequency, can
bend around objects and skip along the ground.
In addition, the signals can be bounced off the
ionosphere and bent back to earth. Because of
these characteristics. AM signals are also sub-
ject to interference as they travel from transmit-
ter to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas with
many tall buildings. It can also occur for several
seconds during ionospheric turbulence even in
areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic
lights.Satellite radio reception :
When the satellite radio is used for the first time
or the battery has been replaced, the satellite
radio may not work properly. This is not a
malfunction. Wait more than 10 minutes with
the satellite radio ON and the vehicle outside of
any metal or large building for the satellite
radio to receive all of the necessary data.
The satellite radio mode requires an active XM
Satellite Radio subscription. The satellite radio
is not available in Alaska, Hawaii and Guam.
The satellite radio performance may be affected
if cargo carried on the roof blocks the satellite
radio signal.
If possible, do not put cargo near the satellite
antenna.
A build up of ice on the satellite radio antenna
can affect satellite radio performance. Remove
the ice to restore satellite radio reception.
Compact Disc (CD) player
●
Do not force a compact disc into the CD
insert slot. This could damage the CD and/or
CD changer/player.
