Operating tips
●Keep the windows closed while the air con-
ditioner is in operation.
● After 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.
● The 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.
● A 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.

●If 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.

LHA2059
4-14Heater, air conditioner, audio and phone systems

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
Place the ignition switch in the ACC or ON
position and press the PWR (power)/VOL (vol-
ume) knob 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 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.

using a suitable tool such as an open-end
wrench. The antenna rod tightening specification
is 3.4 – 3.6 N·m (30 – 32 in-lb) . Do not use pliers
to tighten the antenna as they can leave marks on
the antenna surface. The antenna rod cannot be
hand tightened to the proper specification.
CAUTION
Always properly tighten the antenna rod
during installation or the antenna rod may
break during vehicle operation. When installing a CB, ham radio or car phone in
your NISSAN, be sure to observe the following
precautions; otherwise, the new equipment may
adversely affect the engine control system and
other electronic parts.
