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 min-
utes with the windows open to vent hot air
from the passenger compartment. Then, close
the windows. This allows the air conditioner to
cool the interior more quickly.
cThe air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps prevent
damage to the system due to lack of
lubrication.
cIf the engine coolant temperature gauge
indicates engine coolant temperature
over the normal range, turn the air con-
ditioner off. See “If your vehicle over-
heats” in the “In case of emergency”
section of this manual.

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.

cA new disc may be rough on the inner and
outer edges. Remove the rough edges by rub-
bing the inner and outer edges with the side of
a pen or pencil as illustrated.
ANTENNA
The antenna cannot be shortened, but can be
removed. When you need to remove the antenna,
turn the antenna rod counterclockwise.
To install the antenna rod, turn the antenna clock-
wise. Tighten the antenna rod to specification
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
cautions, otherwise the new equipment may ad-
versely affect the MFI (Multiport Fuel Injection)
system and other electronic parts.
WARNING
cA cellular telephone should not be used
while driving so full attention may be
given to vehicle operation. Some juris-
dictions prohibit the use of cellular tele-
phones while driving.
cIf you must make a call while your ve-
hicle is in motion, the hands free cellu-
lar phone operational mode (if so
equipped) is highly recommended. Ex-
ercise extreme caution at all times so
full attention may be given to vehicle
operation.
cIf a conversation in a moving vehicle
requires you to take notes, pull off the
road to a safe location and stop your
vehicle before doing so.
CAUTION
cKeep the antenna as far away as pos-
sible from the Engine Control Module
(ECM) .
cKeep the antenna wire more than 8 in
(20 cm) away from the Multiport Fuel
Injection harness. Do not route the an-
tenna wire next to any harness.
cAdjust the antenna standing-wave ratio
as recommended by the manufacturer.
cConnect the ground wire from the CB
radio chassis to the body.
cFor details, consult a NISSAN dealer.
