2002 NISSAN ALTIMA heater

Operating tips
cKeep the windows and sun roof closed
while the air conditioner is in operation.
cAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This
allows the air conditioner to cool the
interior more quickly.
cThe air conditioner system should be
operated for approximately ten min-
utes at least once a month. This helps
prevent damage to the system due to
lack of lubrication.
cIf the engine coolant temperature gauge
exceeds the H (hot) position, turn the air
conditioner off. See ``If your vehicle over-
heats'' in the ``In case of emergency''
section of this Owner's Manual for addi-
tional information.

WARNING
cThe air conditioner cooling function
operates only when the engine is
running.cDo not leave children, impaired
adults, or pets alone in your vehicle.
On hot, sunny days, temperatures in
a closed vehicle could quickly be-
come high enough to cause severe orpossibly fatal injuries to people or
animals.
cDo not use the recirculation mode
for long periods as it may cause the
interior air to become stale and the
windows to fog up.
cPositioning of the heating or air con-
ditioning controls should not be
done while driving, so full attention
may be given to vehicle operation.
Start the engine and operate the controls to
activate the air conditioner.
AUTOMATIC OPERATION
Cooling and/or dehumidified heat-
ing (AUTO)
This mode may be normally used all year
round as the system automatically works to
keep a constant temperature. Air flow distri-
bution and fan speed are also controlled
automatically.
1. Push the AUTO button on. (AUTO will be
displayed.)
2. Turn the temperature dial to the left or
right to set the desired temperature.

cAdjust the temperature dial to about 75ÉF
(24ÉC) for normal operation.
cThe temperature of the passenger com-
partment will be maintained automati-
cally. Air flow distribution and fan speed
are also controlled automatically.
Heating (ECON)
The air conditioner does not activate. When
you need to heat only, use this mode.
1. Push the ECON (Economy) button on.
(ECON will be displayed.)
2. Turn the temperature dial to the left or
right to set the desired temperature.
cThe temperature of the passenger com-
partment will be maintained automati-
cally. Air flow distribution and fan speed
are also controlled automatically.
cDo not set the temperature lower than
the outside air temperature. Otherwise
the system may not work properly.
cNot recommended if windows fog up.
Dehumidified defogging
1. Push the DEF buttonon. The in-
dicator light on the button will come on.2. Turn the temperature dial to the left or
right to set the desired temperature.
cTo quickly remove ice from the outside of
the windows, push the manual fan con-
trol button
and set to the maxi-
mum position
.
cAs soon as possible after the windshield
is clean, push the AUTO button to return
to the auto mode.
cWhen the DEF button
is pushed,
the air conditioner will automatically be
turned on at outside temperatures above
23ÉF (þ5ÉC) to defog the windshield, and
the air recirculate mode will automatically
be turned off.
Outside air is drawn into the passenger
compartment to improve the defogging
performance.
MANUAL OPERATION
Fan speed control
Push the fan control buttonto manu-
ally control the fan speed.
Push the AUTO button to return to auto-
matic control of the fan speed.
Air recirculation
Push the air recirculation buttonto
recirculate interior air inside the vehicle. The
indicator light on the switch will come on.
Push it again to make the air inlet controlled
automatically (FRESH, REC/FRE and RE-
CIRCULATION). The indicator will go out.
The air recirculation button will not be acti-
vated when the air conditioner is in DEF
mode.
Air flow control
Pushing the manual air flow control button
selects the air outlet to:
: Air flows from center and side ventila-
tors.
: Air flows from center and side ventila-
tors and foot outlets.
: Air flows mainly from foot outlets.
: Air flow from defroster and foot out-
lets.
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 temperature warms up, air
flow from the foot outlets will operate
normally.
The sunload sensor, located on the top
passenger side of the instrument panel,
helps maintain a constant temperature. Do
not put anything on or around this sensor.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. See ``Air conditioner
system refrigerant and lubricant recommen-
dations'' in the ``Technical and consumer
information'' section of this manual.
Your NISSAN dealer is able to service your
environmentally ``friendly'' air conditioning
system.
WARNING
The air conditioner system contains
refrigerant under high pressure. To
avoid personal injury, any air condi-
tioner service should be done only by
an experienced technician with proper
equipment.

RADIO
Turn the ignition key to ACC or ON and
press the power on switch to turn on the
radio. 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,
buildings, bridges, mountains and other ex-
ternal 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 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 character-
istics of both FM and AM radio signals that
can affect radio reception quality in a mov-
ing vehicle, even when the finest equipment
is used. These characteristics are com-pletely 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 interference
from other vehicles can work against ideal
reception. Described below are some of the
factors that can affect your radio reception.
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 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 antennaposition (usually in conjunction with in-
creased distance from the station transmit-
ter) static or flutter can be heard. This can
be reduced by adjusting the treble control
counterclockwise to reduce treble re-
sponse.
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 turbu-
lence even in areas where no obstacles
exist.
Static: Caused by thunderstorms, electrical

player completely.
cThe player may skip while driving on
rough roads.
cThe CD player sometimes cannot
function when the compartment tem-
perature is extremely high. Decrease
the temperature before use.
cDo not expose the CD to direct sun-
light.
