WARNING
• The distance guide lines and the ve-
hicle width lines should be used as a
reference only when the vehicle is on
a paved, level surface. The apparent
distance viewed on the monitor may
be different than the actual distance
between the vehicle and displayed
objects.
• Use the displayed lines and the
bird’s-eye view as a reference. The
lines and the bird’s-eye view are
greatly affected by the number of oc-
cupants, cargo, fuel level, vehicle po-
sition, road condition and road
grade.
• If the tires are replaced with different
sized tires, the predicted course lines
and the bird's-eye view may be dis-
played incorrectly. •
When driving the vehicle up a hill, ob-
jects viewed in the monitor are fur-
ther than they appear. When driving
the vehicle down a hill, objects
viewed in the monitor are closer than
they appear.
• Objects in the rear view will appear
visually opposite compared to when
viewed in the monitor and outside
mirrors.
• Use the mirrors or actually look to
properly judge distances to other
objects.
• On a snow-covered or slippery road,
there may be a difference between
the predicted course lines and the
actual course line.
• The vehicle width and predicted
course lines are wider than the actual
width and course.
• The displayed lines will appear
slightly off to the right, because the
rearview camera is not installed in
the rear center of the vehicle.

– When camera orientation is not in
its usual position, such as when a
mirror is folded.
– When there is dirt, water drops or
snow on the camera lens.
– When the position of the moving
objects in the display is not
changed.
• The MOD system might detect flow-
ing water droplets on the camera
lens, white smoke from the muffler,
moving shadows, etc.
• The MOD system may not function
properly depending on the speed, di-
rection, distance or shape of the
moving objects. •
If your vehicle sustains damage to
the parts where the camera is in-
stalled, leaving it misaligned or bent,
the sensing zone may be altered and
the MOD system may not detect ob-
jects properly.
• When the temperature is extremely
high or low, the screen may not dis-
play objects clearly. This is not a
malfunction.
NOTE:

AUDIO OPERATION PRECAUTIONS
MP3 or WMA terms
•MP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is the
most well-known compressed digital au-
dio file format. This format allows for near
“CD quality” sound, but at a fraction of the
size of normal audio files. MP3 conversion
of an audio track from CD-ROM can reduce
the file size by approximately a 10:1 ratio
with virtually no perceptible loss in quality.
MP3 compression removes the redundant
and irrelevant parts of a sound signal that
the human ear doesn’t hear.
• WMA — Windows Media Audio (WMA)* is a compressed audio format created by Mi-
crosof t as an alternative to MP3. The WMA
codec offers greater file compression
than the MP3 codec, enabling storage of
more digital audio tracks in the same
amount of space when compared to
MP3s at the same level of quality. • Bit rate — Bit rate denotes the number of
bits per second used by a digital music
file. The size and quality of a compressed
digital audio file is determined by the bit
rate used when encoding the file.
• Sampling frequency — Sampling fre- quency is the rate at which the samples
of a signal are converted from analog to
digital (A/D conversion) per second.
• Multisession — Multisession is one of the methods for writing data to media. Writ-
ing data once to the media is called a
single session, and writing more than
once is called a multisession.
• ID3/WMA Tag — The ID3/WMA tag is the part of the encoded MP3 or WMA file that
contains information about the digital
music file such as song title, artist, encod-
ing bit rate, track time duration, etc. ID3
tag information is displayed on the Artist/
song title line on the display.

USB (Universal Serial Bus)
Connection Port
WARNING
• Do not connect, disconnect or oper-
ate the USB device while driving. Do-
ing so can be a distraction. If dis-
tracted you could lose control of your
vehicle and cause an accident or se-
rious injury.
CAUTION
• Do not force the USB device into the
USB port. Inserting the USB device
tilted or up-side-down into the port
may damage the port. Make sure
that the USB device is connected cor-
rectly into the USB port.
• Do not grab the USB port cover (if so
equipped) when pulling the USB de-
vice out of the port. This could dam-
age the port and the cover.
• Do not leave the USB cable in a place
where it can be pulled unintention-
ally. Pulling the cable may damage
the port.
4-46Monitor, climate, audio, phone and voice recognition systems

Additional information:
• When using a wheel without the TPMSsuch as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle is driven at speeds above 16 mph (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example,
a flat tire while driving).
• The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted on all four tires. Af ter
all four tires are inflated to the recom-
mended pressure, the vehicle must be
driven at speeds above 16 mph (25 km/h)
to activate the TPMS and turn off the low
tire pressure warning light. Use a tire
pressure gauge to check the tire
pressure.
• The “Tire Pressure Low - Add Air” warning appears in the vehicle information dis-
play when the low tire pressure warning
light is illuminated and low tire pressure is
detected. The “Tire Pressure Low - Add
Air” warning turns off when the low tire
pressure warning light turns off. • The “Tire Pressure Low - Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
• The “Tire Pressure Low - Add Air” warning does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
• Tire pressure rises and falls depending on the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure af ter driving be-
cause the tire pressure rises af ter driving.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates, check the tire
pressure for all four tires.
• The Tire and Loading Information label is located in the driver's door opening.
• You can also check the tire pressure of all tires (except the spare) on the vehicle in-
formation display screen. The order of
the tire pressure figures displayed on the
screen corresponds with the actual order
of the tire position. For additional information, see “Low tire
pressure warning light” (P. 2-13), “Tire Pres-
sure Monitoring System (TPMS)” (P. 6-3) and
“Tire pressure” (P. 8-29).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
5-6Starting and driving

•If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with underinflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light off. If you have
a flat tire, replace it with a spare tire
as soon as possible. (For additional
information, see “Flat tire” (P. 6-3) for
changing a flat tire.) •
When using a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, tire pressure will not be in-
dicated, the TPMS will not function
and the low tire pressure warning
light will flash for approximately 1
minute. The light will remain on af ter
1 minute. It is recommended that you
visit a NISSAN dealer for tire replace-
ment and/or system resetting.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CAUTION
Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception of
the signals from the tire pressure sen-
sors, and the TPMS will not function
properly. Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate.
Some examples are:
• Facilities or electric devices using similar
radio frequencies are near the vehicle.
• If a transmitter set to similar frequencies is being used in or near the vehicle.
• If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may
illuminate in the following cases:
• If the vehicle is equipped with a wheel and tire without TPMS.
• If the TPMS has been replaced and the ID has not been registered.
• If the wheel is not originally specified by NISSAN.
