HEATER OPERATION
Heating
This mode is used to direct heated air to the foot
outlets. Some air also flows from the defrost
outlets and outboard vents.
1. Push the
button to the off position for
normal heating.
2. Turn the air flow control dial to the
position.
3. Turn the fan control dial to the desired posi-
tion.
4. Turn the temperature control dial to the de-
sired position between the middle and the
hot position.
Ventilation
This mode directs outside air to the side and
center ventilators.
1. Push the
button to the off position.
2. Turn the air flow control dial to the
position.
3. Turn the fan control dial to the desired posi-
tion.
4. Turn the temperature control dial to the de-
sired position.
Defrosting or defogging
This mode directs the air to the defrost outlets and
outboard vents to defrost/defog the windows.
1. Turn the air flow control dial to theposition.
2. Turn the fan control dial to the desired posi-
tion.
3. Turn the temperature control dial to the de-
sired position between the middle and the
hot position.
cTo quickly remove ice or fog from the win-
dows, turn the fan control dial to HI and the
temperature control lever to the full HOT
position.
cWhen the
position is selected, the air
conditioner automatically turns on (however,
the indicator light will not illuminate) . In this
position, the A/C cannot be turned off.
When the air flow control is turned to any
position other than
orthe A/C
light will illuminate (the A/C will continue
operating) and can be turned off using the
A/C button. This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing out-

When the
orposition is selected,
the air conditioner automatically turns on (how-
ever, the indicator light will not illuminate) . In this
position, the A/C cannot be turned off. When the
air flow control is turned to any position other
than
orthe A/C light will illuminate
(the A/C will continue operating) and can be
turned off using the A/C button. This dehumidi-
fies the air which helps defog the windshield.
The
mode automatically turns off, allowing
outside air to be drawn into the passenger com-
partment to further improve the defogging perfor-
mance.4. Turn the temperature control dial to the de-
sired position.
Operating tips
cKeep the windows and moonroof 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.
cA 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.
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.

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 oil recommendations” in the “Technical 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/VOLUME control knob 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.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the de-
vice in a different location may reduce or elimi-
nate 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. Exter-
nal influences may sometimes interfere with FM
station reception 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 follow a line-
of-sight path, exhibiting many of the same char-
acteristics 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.
