4. Push thebutton. The indicator light
comes on.
5. Turn the temperature control dial to the de-
sired position.
Dehumidified defogging
This mode is used to defog the windows and
dehumidify the air.
1. Turn the air flow control dial to the
position.
2. Turn the fan control dial to the desired posi-
tion.
3. Push the
button. The indicator light
comes on.
When the
,or positions in between
are selected, the air conditioner automatically
turns on (however, the indicator light will not
illuminate) if the outside temperature is more than
36 - 37°F (2 - 3°C) . The air conditioning system
will continue to operate until the fan control dial is
turned to OFF or the vehicle is shut off, even if the
air flow control dial is turned to a position other
than the
position. This dehumidifies the air
which helps defog the windshield. The
mode automatically turns off, allowing outside air
to be drawn into the passenger compartment to
further improve the defogging performance.4. Turn the temperature control dial to the de-
sired position.
Operating tips
cKeep the windows and sunroof closed while
the air conditioner is in operation.
cAfter parking in the sun, drive for 2 or 3
minutes with the windows open to vent hot
air from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
cThe air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See “If your
vehicle overheats” in the “In case of
emergency” section of this manual.

— Air flows from center and side
ventilators.
— Air flows from center and side
ventilators and foot outlets.
— Air flows mainly from foot outlets.
— Air flows from defroster and foot
outlets.
To turn system off
Push the OFF button.
OPERATING TIPS
cWhen the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally.The sunload sensor, located on the top passen-
ger side of the instrument panel, helps the system
maintain a constant temperature. Do not put any-
thing on or around this sensor.The air conditioner system in your NISSAN ve-
hicle is charged with a refrigerant designed with
the environment in mind.
This refrigerant does not harm the earth’s
ozone layer.
Special charging equipment and lubricant is re-
quired when servicing your NISSAN air condi-
tioner. Using improper refrigerants or lubricants
will cause severe damage to your air conditioner
system. See “Air conditioner system refrigerant
and lubricant recommendations” in the “Techni-
cal and consumer information” section of this
manual.
A NISSAN dealer is able to service your “environ-
mentally friendly” air conditioning 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
Turn the ignition key to the ACC or ON position
and press the power on switch to turn the radio
on. If you listen to the radio with the engine not
running, the key should be turned to the ACC
position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external influ-
ences. 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 enhance ra-
dio reception. These circuits are designed to
extend reception range, and to enhance the qual-
ity 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 char-
acteristics are completely normal in a given re-
ception area, and do not indicate any malfunction
in your NISSAN radio system.Reception conditions will constantly change be-
cause of vehicle movement. Buildings, terrain,
signal distance and interference from other ve-
hicles can work against ideal reception. De-
scribed below are some of the factors that can
affect your radio reception.
FM RADIO RECEPTION
Range: FM range is normally limited to 25 - 30
miles (40 - 48 km) , with monaural (single chan-
nel) 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 receiver. 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.
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 adjusting the
treble control to reduce treble response.Multipath reception: Because of the reflective
characteristics of FM signals, direct and reflected
signals reach the receiver at the same time. The
signals may cancel each other, resulting in mo-
mentary 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 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 turbulence even in
areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic lights.
