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.

STEERING WHEEL SWITCH FOR
AUDIO CONTROL (if so equipped)
The steering wheel switch for audio controls is
mounted on the left side of the steering wheel.
Press the MODE button to turn the radio on or, if
the radio is already on, to switch between the
Radio presets (A, B or C) and CD Mode.
A!B!C!CD ModeThe last CD that was loaded starts to play when
in CD Mode. If there is no CD loaded, the CD
changer enters Disc Loading Mode.
If in Radio presets A, B or C:
cPress
or(<1.5 seconds) to ad-
vance to the next preset station or to return to
the previous preset station.
cHold down
or(>1.5 seconds) .
The radio will seek up or down to the next radio
station.
If in CD Mode:
cPress
or(<1.5 seconds) to ad-
vance to the next selection on the CD or return
to the previous selection on the CD.
cHold down
or(>1.5 seconds) to
advance to the next CD or return to the previ-
ous CD.
Volume control is located on the side of the audio
control switch. Press the top of the volume con-
trol to increase volume. Press the bottom of the
volume control to decrease volume.
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.

UNDERBODY
In areas where road salt is used in winter, it is
necessary to clean the underbody regularly in
order to prevent dirt and salt from building up and
causing the acceleration of corrosion on the un-
derbody and suspension. Before the winter pe-
riod and again in the spring, the underseal must
be checked and, if necessary, retreated.
GLASS
Use glass cleaner to remove smoke and dust film
from the glass surfaces. It is normal for glass to
become coated with a film after the vehicle is
parked in the hot sun. Glass cleaner and a soft
cloth will easily remove this film.
CAUTION
When cleaning the inside of the windows,
do not use sharp-edged tools, abrasive
cleaners or chlorine-based disinfectant
cleaners. They could damage the electri-
cal conductors, radio antenna elements or
rear window defroster elements.
ALUMINUM ALLOY WHEELS
Wash the wheels regularly, especially during win-
ter months in areas where road salt is used. If not
removed, road salt could discolor the wheels.
CHROME PARTS
Clean all chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft brush. Wipe the vinyl and leather
surfaces with a clean, soft cloth dampened in
mild soap solution, then wipe clean with a dry,
soft cloth. Before using any fabric protector, read
the manufacturer’s recommendations. Some fab-
ric protectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water to clean
the meter and gauge lens.
CAUTION
cNever use benzine, thinner or any simi-
lar material.
cThe leather seats should be regularly
coated with a leather wax like saddle
soap. Never use car wax.
cNever use fabric protectors unless rec-
ommended by the manufacturer.
cDo not use glass or plastic cleaner on
meter or gauge lens covers. It may dam-
age the lens cover.
