Flicker image (example)
. When LED headlights are viewed on the
Smart Rearview Mirror display, the
images may flicker. This is normal.
. Due to diffused reflection from external
environment, images on the screen may
flicker. This is not a malfunction.
. A quick movement of a thing may not be
able to display on the camera view
screen. This is not a malfunction.
. Turn on the headlights at twilight or in a
tunnel, etc.
. The Smart Rearview Mirror mode (cam-
era view mode) display is different from
the conventional rearview mirror. Ob-
jects in the display may differ from actual distance. Do not solely rely on
the Smart Rearview Mirror. Always rely
on your own operation to avoid acci-
dents.
. If the brightness of the camera view
display is adjusted to excessive bright
level, it may cause an eyestrain in the
driving. Adjust the brightness properly.
. Use the rear window wiper when it rains.
If the camera view image is still unclear
when the rear window wiper is in
operation, check the deterioration of
the rear window wiper blade.
. When using the rear window wiper,
images on the screen may flicker. This
is not a malfunction.
. Defog the rear window with defroster
when rear window is fogged. Use the
conventional rearview mirror mode until
the rear window is fully defogged.
. The display of the Smart Rearview
Mirror may become hot. This is not a
malfunction.
. The color of an object in the distance or
in the dark may be difficult to be
recognized. This is not a malfunction.
System maintenance (Smart Rearview
Mirror):
. Always keep the mirror and camera area
of the rear window clean.

SONAR SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the sonar function. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system, including
reduced performance or a false acti-
vation.
. The system is not designed to pre-
vent contact with small or moving
objects.
. The system will not detect small
objects below the bumper, and may
not detect objects close to the bum-
per 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 measure-
ment of objects or false alarms.
CAUTION
Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
See “Front and rear sonar system” (P.5-126)
for more information on the sonar system
and limitations.
System temporarily unavailable
When the amber markers are displayed at
the corners of the vehicle icon and the

OPERATING TIPS
When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate.
However, this is not a malfunction. After
the coolant temperature warms up, the air
flow from the foot outlets will operate
normally.
The sensors
andlocated on the instru-
ment panel help maintain a constant tem-
perature. Do not put anything on or around
the sensors.
LINKING INTELLIGENT KEY
The air conditioner system settings can be
memorized for each Intelligent Key. See
“Setting memory function” (P.3-41).
IN-CABIN MICROFILTER
Models without Advanced Climate Control
System:
The climate control system is equipped with
an in-cabin microfilter which collects dirt,
pollen, dust, etc.
Models with Advanced Climate Control
System:
The climate control system is equipped with
a natural grape seed polyphenol filter which
collects and neutralizes dirt, pollen, dust, etc.
To make sure the air conditioner heats, defogs, and ventilates efficiently, replace
the filter in accordance with the specified
maintenance intervals listed in the “9. Main-
tenance and schedules” section. If replace-
ment is required, it is recommended you visit
an INFINITI retailer for this service.
The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air
conditioner.
SERVICING CLIMATE CONTROL
The climate control system in your vehicle is
charged with a refrigerant designed with the
environment in mind.
This refrigerant will
not harm the earth’s ozone layer. However,
special charging equipment and lubricant are
required when servicing your air conditioner.
Using improper refrigerants or lubricants will
cause severe damage to your climate control
system. (See “Capacities and recommended
fluids/lubricants” (P.10-2) for climate con-
trol system refrigerant and lubricant recom-
mendations.)
An INFINITI retailer will be able to service
your environmentally friendly climate control
system.
WARNING
The system contains refrigerant under
high pressure. To avoid personal injury,
any air conditioner service should be
done only by an experienced technician
with the proper equipment.

CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
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 overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly. It is recommended
you visit an INFINITI retailer 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 Mon-
itoring System (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires is significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check 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 sub-
stitute for proper tire maintenance, and it is
the driver’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 com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Additional information
.
Since the spare tire is not equipped with
the TPMS, the TPMS does not monitor
the tire pressure of the spare tire.
. The TPMS will activate only when the
vehicle is driven at speeds above 16
MPH (25 km/h). Also, this system may
