•Objects in the RearView Monitor will ap-
pear visually opposite compared to when
viewed in the rearview and outside
mirrors.
• Use the displayed lines as a reference.
The lines are highly affected by the num-
ber of occupants, fuel level, vehicle posi-
tion, road conditions and road grade.
• Make sure that the liftgate is securely
closed when backing up.
• Do not put anything on the rearview
camera. The rearview camera is installed
above the license plate.
• When washing the vehicle with high
pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing water
condensation on the lens, a malfunction,
fire or an electric shock.
• Do not strike the camera. It is a precision
instrument. Otherwise, it may malfunc-
tion or cause damage resulting in a fire or
an electric shock. The following are operating limitations and
do not represent a system malfunction:
• When the temperature is extremely high or
low, the screen may not clearly display
objects.
• When strong light directly shines on the camera, objects may not be displayed
clearly.
• Vertical lines may be seen in objects on the screen. This is due to strong reflected light
from the bumper.
• The screen may flicker under fluorescent light.
• The colors of objects on the RearView Monitor may differ somewhat from the ac-
tual color of objects.
• Objects on the monitor may not be clear in a dark environment.
• There may be a delay when switching be- tween views.
• If dirt, rain or snow accumulate on the cam- era, the RearView Monitor may not display
objects clearly. Clean the camera.
• Do not use wax on the camera lens. Wipe off any wax with a clean cloth dampened
with a diluted mild cleaning agent, then
wipe with a dry cloth.
SYSTEM MAINTENANCE
CAUTION
• Do not use alcohol, benzine or thinner to
clean the camera. This will cause
discoloration.
• Do not damage the camera as the moni-
tor screen may be adversely affected.
If dirt, rain or snow accumulates on the cam-
era
O1, the RearView Monitor may not dis-
play objects clearly. Clean the camera by wip-
ing it with a cloth dampened with a diluted
mild cleaning agent and then wiping it with a
dry cloth.

SYSTEM MAINTENANCE
CAUTION
• Do not use alcohol, benzine or thinner to
clean the camera. This will cause
discoloration.
• Do not damage the cameras as the moni-
tor screen may be adversely affected.
If dirt, rain or snow accumulates on any of the
cameras
O1, the Around View® Monitor may
not display objects clearly. Clean the camera
by wiping with a cloth dampened with a di-
luted mild cleaning agent and then wiping
with a dry cloth.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar function
as outlined in this section could result in
serious injury or death.
• The sonar is a convenience feature. It is
not a substitute for proper parking.
• This function is designed as an aid to the
driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
• The driver is always responsible for
safety during parking and other
maneuvers.
• Always look around and check that it is
safe to move before parking.
• Read and understand the limitations of
the sonar as contained in this section.
The sonar function helps to inform the driver
of large stationary objects around the vehicle
when parking by issuing an audible and visual
alert.

sensor) (if so equipped)
Monitor, climate, audio, phone and voice recognition systems4-23

•The system will not detect small objects
below the bumper, and may not detect
objects close to the bumper or on the
ground.
• The system may not detect the following
objects:
– Fluffy objects such as snow, cloth,
cotton, grass or wool.
– Thin objects such as rope, wire or
chain.
– Wedge-shaped objects.
• If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
jects or false alarms.
CAUTION
Excessive noise (such as audio system vol-
ume or an open vehicle window) will inter-
fere with the tone and it may not be heard.
System temporarily unavailable
When the amber markers are displayed at the
corners of the vehicle icon and the function
cannot be activated from the Camera setting
menu (the setting items are grayed out), the
sonar system may be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors (lo-
cated on the front and rear bumper fascia)
free from accumulations of snow, ice and
dirt. Do not scratch the surface of the sonar
sensors when cleaning. If the sensors are
covered, the accuracy of the sonar function
will be diminished.
Monitor, climate, audio, phone and voice recognition systems4-27

•If your vehicle sustains damage to the
parts where the camera is installed, leav-
ing it misaligned or bent, the sensing
zone may be altered and the MOD sys-
tem may not detect objects properly.
• When the temperature is extremely high
or low, the screen may not display ob-
jects clearly. This is not a malfunction.
NOTE:
The blue or green MOD icon will change to
orange if one of the following has occurred:
• When the system is malfunctioning.
• When the component temperature reaches a high level (icon will blink).
• When the Rear View camera has detected a blockage (icon will blink).
If the icon light continues to illuminate or-
ange, have the MOD system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
SYSTEM MAINTENANCE
CAUTION
• Do not use alcohol, benzine or thinner to

O1, the MOD system may not oper-
ate properly. Clean the camera by wiping

CAUTION
• Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst's ability to
help reduce exhaust pollutants.
• Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over rich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
• Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
• Do not race the engine while warming it
up.
• Do not push or tow your vehicle to start
the engine.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels al-
low the TPMS to continue to function
properly.
