• When the climate system is in automaticoperation and the engine coolant tem-
perature and outside air temperature are
low, the air flow outlet may default to de-
froster mode for a maximum of 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant
temperature warms up, the air flow outlet
will return to foot mode and operation will
continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may occur
when the previous climate setting was
turned off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, the air
flow outlet will return to previous settings,
and operation will continue normally. To
exit, press any climate control button.
• Keep the moonroof (if so equipped) closed while the air conditioner is in
operation. • If you feel that the air flow mode you have
selected and the outlets the air is coming
out do not match, select the
mode.
• When you change the air flow mode, you may feel air flow from the foot outlets for
just a moment. This is not a malfunction. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth's ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, see “Air conditioner system re-
frigerant and oil recommendations”
(P. 10-8).
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly ” air conditioner system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.

RADIO
Place the ignition switch in the ACC or ON
position and press the PUSHbutton
to turn the radio on. If you listen to the radio
with the engine not running, the ignition
switch should be placed in the ACC
position.
Radio reception is affected by station sig-
nal strength, distance from radio transmit-
ter, 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 ve-
hicle may influence radio reception
quality.
Radio reception
Your NISSAN 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 charac-
teristics 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 malfunction
in your NISSAN radio system.
Reception conditions will constantly
change because of vehicle movement.
Buildings, terrain, signal distance and inter-
ference 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 –
30 mi (40 – 48 km), with monaural (single
channel) FM having slightly more range
than stereo FM. External influences may
sometimes interfere with FM station re-
ception even if the FM station is within 25
mi (40 km). The strength of the FM signal is
directly related to the distance between
the transmitter and receiver. FM signals fol-
low a line-of-sight path, exhibiting many of
the same characteristics as light. For ex-
ample, they will reflect off objects.
Fade and drif t: As your vehicle moves away
from a station transmitter, the signals will
tend to fade and/or drif t.
Static and flutter: During signal interfer-
ence 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 adjusting the treble
control to reduce treble response.
Multipath reception: Because of the reflec-
tive characteristics of FM signals, direct and
reflected signals reach the receiver at the
same time. The signals may cancel each
other, resulting 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 subject to interference
as they travel from transmitter 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 tur-
bulence even in areas where no obstacles
exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic
lights.
AUDIO OPERATION PRECAUTIONS
MP3 or WMA terms
•MP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is the
most well-known compressed digital au-
dio file format. This format allows for near
“CD quality” sound, but at a fraction of the
size of normal audio files. MP3 conversion
of an audio track from CD-ROM can reduce
the file size by approximately a 10:1 ratio
with virtually no perceptible loss in quality.
MP3 compression removes the redundant
and irrelevant parts of a sound signal that
the human ear doesn’t hear.
• WMA — Windows Media Audio (WMA)* is a compressed audio format created by Mi-
crosof t as an alternative to MP3. The WMA
codec offers greater file compression
than the MP3 codec, enabling storage of
more digital audio tracks in the same
amount of space when compared to
MP3s at the same level of quality. • Bit rate — Bit rate denotes the number of
bits per second used by a digital music
file. The size and quality of a compressed
digital audio file is determined by the bit
rate used when encoding the file.
• Sampling frequency — Sampling fre- quency is the rate at which the samples
of a signal are converted from analog to
digital (A/D conversion) per second.
• Multisession — Multisession is one of the methods for writing data to media. Writ-
ing data once to the media is called a
single session, and writing more than
once is called a multisession.
• ID3/WMA Tag — The ID3/WMA tag is the part of the encoded MP3 or WMA file that
contains information about the digital
music file such as song title, artist, encod-
ing bit rate, track time duration, etc. ID3
tag information is displayed on the Artist/
song title line on the display.
