1999 NISSAN PATHFINDER Owners Manual

Operating tipsIKeep windows and sun roof closed while
the air conditioner is in operation.
IAfter 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 will
allow the air conditioner to cool the interior
more quickly.
IThe air conditioning system should be
operated for about ten minutes at least
once a month. This helps prevent dam-
age to the system due to lack of lubrica-
tion.
IIf the coolant temperature gauge exceeds
the hot position, turn the air conditioner off.
For additional information, see ªIf your ve-
hicle overheatsº in the ª6. In case of emer-
gencyº section.AIR FLOW CHARTSThe following charts show the button and dial
positions formaximum and quickheating,
cooling or defrosting.The air recirculation
switch should always be in the off position
for heating and defrosting.4-6

Start the engine and operate the controls to
activate the air conditioner.IThe air conditioner cooling function
operates only when the engine is run-
ning.
IDo not leave children, unreliable
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 or
possibly fatal injuries to people or
animals.
IDo not use the recirculation mode for
long periods as it may cause the
interior air to become stale and the
windows to fog up.
IPositioning of the heating or air con-
ditioning controls should not be done
while driving, in order that full atten-
tion may be given to the driving
operation.

AUTOMATIC OPERATION
Cooling and/or dehumidified heating
(AUTO)This mode may be used all year round. The
system works automatically to maintain a
constant temperature. Air flow distribution and
fan speed are also controlled automatically.
1. Push the AUTO button on. (AUTO will
appear on the display.)
2. Push the temperature control button
to set the desired temperature.
IFor normal operation, adjust the tempera-
ture control button to about 75ÉF (24ÉC).
IThe temperature of the passenger compart-
ment will be maintained automatically. Air
flow distribution and fan speed are also
controlled automatically.
Heating (ECON)Use this mode when you need to heat only.
1. Push the ECON (Economy) button on.
(ECON appears on the display.)
2. Push the temperature control button
to set the desired temperature.
IThe temperature of the passenger compart-ment will be maintained automatically. Air
flow distribution and fan speed are also
controlled automatically.
IDo not set the temperature lower than the
outside air temperature. Otherwise the sys-
tem may not work properly.
IIf the windows fog up, do not use the ECON
mode.
Dehumidified defogging1. Push the DEF
switch on. (The indica-
tor light will come on.)
2. Push the temperature control button
to set the desired temperature.
ITo remove ice or fog from the outside of the
windows, push the manual fan control but-
tonand set to the maximum position.
IAs soon as possible after the windshield is
clean, push the AUTO button to return to
the auto mode.
IWhen the DEF
button is pushed, the
air conditioner will automatically be turned
on at outside temperatures above 32ÉF
(0ÉC) to defog the windshield. The air
recirculation mode will automatically be
turned off.
Outside air is drawn into the passenger com-partment to improve defogging performance.
MANUAL OPERATION
Fan speed controlPush the fan control button
to change
the fan speed manually.
IPush the AUTO button to return to auto-
matic control of the fan speed.
Air recirculationPush the air recirculation button
to recir-
culate interior air inside the vehicle. The indi-
cator light will come on.
Push it again to draw outside air into the
passenger compartment. The indicator will go
out.
IThe air recirculation button cannot be
activated when the air conditioner is in the
DEF mode.
Air flow controlPushing the MODE button selects the air outlet
to provide:
: Air flow from center and side ventilators.: Air flow from center and side ventilators
and foot outlets.

: Air flow mainly from foot outlets.: Air flow from defroster and foot outlets.
To turn the system offPush the OFF button.OPERATING TIPSIWhen the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for 0
to 126 seconds. This is not a malfunction.
After the coolant temperature warms up, air
flow from the foot outlets will operate nor-
mally.
The sensor on the instrument panel helps
maintain a constant temperature. Do not put
anything on or around this sensor.The air conditioning system in your NISSAN
vehicle 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 lu-
bricant are required when servicing your
NISSAN air conditioner. Using improper refrig-
erants or lubricants will cause severe damage
to your air conditioning system. See ªCapaci-
ties and recommended fuel/lubricantsº in the
ª10. Technical and consumer informationº sec-
tion for air conditioning system refrigerant and
lubricant recommendation.
Your NISSAN dealer will be able to service
your environmentally friendly air conditioning
system.
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 equip-
ment.

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, 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 ve-
hicle may influence radio reception quality.Radio receptionYour radio system is equipped with state-of-
the-art electronic circuits to enhance radio
reception. These circuits are designed to ex-
tend reception range, and to enhance the
quality of that reception.
However there are some general characteris-
tics of both FM and AM radio signals that can
affect radio reception quality in a moving ve-
hicle, 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 radio system.
Remember that a moving vehicle is not the
ideal place to listen to a radio. Because of themovement, reception conditions will constantly
change. 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 RECEPTIONRange: 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 some-
times 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.
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 counterclockwise
to reduce 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,
resulting in momentary flutter or loss of sound.AM RADIO RECEPTIONAM 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 sev-
eral seconds during ionospheric turbulence
even in areas where no obstacles exist.
Static: Caused by thunderstorms, electricalpower lines, electric signs and even traffic
lights.
