WARNING
Failure to follow the warnings and in-
structions for the proper use of the In-
telligent Around View Monitor system
could result in serious injury or death
• The Intelligent Around View Monitor
is a convenience feature and is not a
substitute for proper vehicle opera-
tion because it has areas where ob-
jects cannot be viewed. The four cor-
ners of the vehicle in particular, are
areas where objects do not always
appear in the bird’s-eye, front, or rear
views. Always check your surround-
ings to be sure that it is safe to move
before operating the vehicle. Always
operate the vehicle slowly.
• The driver is always responsible for
safety during parking and other
maneuvers.
CAUTION
Do not scratch the camera lens when
cleaning dirt or snow from the front of
the camera. The Intelligent Around View Monitor sys-
tem is designed as an aid to the driver in
situations such as slot parking or parallel
parking.
The monitor displays various views of the
position of the vehicle in a split screen for-
mat. Not all views are available at all times.
Available views:
• Front View
An approximately 150–degree view of the
front of the vehicle.
• Rear View An approximately 150–degree view of the
rear of the vehicle.
• Bird's-Eye View The surrounding views of the vehicle
from above.
• Front-Side View The view around and ahead of the front
passenger's side wheel.
• Full Screen Rear View (if so equipped) The view to the rear of the vehicle (which
is a little wider than the standard Rear
View). To display the multiple views, the Intelligent
Around View Monitor system uses cam-
eras located in the front grille, on the vehi-
cle’s outside mirrors and one just above
the vehicle’s license plate
O1.

RADIO
Place the ignition switch in the ACC or ON
position and press the PUSHbutton 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 sig-
nal strength, distance from radio transmit-
ter, buildings, 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 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 charac-
teristics 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 characteristics
are completely 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 inter-
ference from other vehicles can work
against ideal reception. Described 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 device in a different location
may reduce or eliminate 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. External influences may
sometimes interfere with FM station re-
ception 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 fol-
low a line-of-sight path, exhibiting many of
the same characteristics as light. For ex-
ample, they will reflect off objects.
Fade and drif t: As your vehicle moves away
from a station transmitter, the signals will
tend to fade and/or drif t.
Static and flutter: During signal interfer-
ence 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 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 tur-
bulence even in areas where no obstacles
exist.
