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.
System temporarily unavailable

Automatic air recirculation control with the
exhaust gas/outside odor detection sensor:
The Advanced Climate Control system
comes with an exhaust gas detection/out-
side odor sensor. When the automatic air
circulation control is activated, the sensor
detects odors outside the vehicle such as
pulp or chemicals, and exhaust gas such as
gasoline or diesel. When such odors or gases
are detected, the display and the system automatically change from the fresh air
mode to the recirculation mode.
When the automatic air circulation control
mode is on, for the first 5 minutes, the air
recirculation mode is selected to prevent
dust, dirt and pollen from entering the
vehicle and to clean the air inside of the
vehicle.
After 5 minutes, the sensor detects exhaust
gas and automatically alternates between
the air recirculation mode and the fresh air
mode.
NOTE:
The automatic air recirculation mode can be
activated under the following conditions.
.
The air flow control is not in the wind-
shield defrosting mode (the indicator
light on
is turned off).
. The outside temperature is approxi-
mately 32 °F (0 °C) or above.
Ion control:
The Advanced Climate Control system unit
generates highly concentrated Plasmaclus-
ter
®ions into the air blown from the
ventilators to reduce odor absorbed into
the interior trim and to suppress airborne
bacteria. The high-density Plasmacluster
®
ions also have a proven skin moisture
preserving effect.

SERVICING AIR CONDITIONER
WARNING
The air conditioner contains refrigerant
under high pressure. To avoid personal
injury, any air conditioner service should
be done only by an experienced techni-
cian with the proper equipment.
The air conditioner 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, it may contribute in a
small part to global warming.
Special charging equipment and lubricant
are required when servicing your vehicle’s air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to the
air conditioner system. (See “Air conditioning
system refrigerant and oil recommenda-
tions” (P.10-7).)
An INFINITI retailer will be able to service your environmentally friendly air conditioner
system.
In-cabin microfilter
With Advanced Climate Control system:
The air conditioning system is equipped with
a natural grape seed polyphenol filter which
collects and neutralizes dirt, pollen, dust, etc.
To make sure that the air conditioner heats,
defogs and ventilates efficiently, replace the
filter in accordance with the specified main-
tenance intervals shown in the “9. Main-
tenance and schedules” section. To replace
the filter, contact an INFINITI retailer.
The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air
conditioner.
Without Advanced Climate Control system:
The air conditioning system is equipped with
an in-cabin microfilter that collects dirt,
pollen, dust, etc.
To make sure that the air conditioner heats,
defogs and ventilates efficiently, replace the
filter in accordance with the specified main-
tenance schedule shown in the “9. Main-
tenance and schedules” section. To replace
the filter, contact an INFINITI retailer.
The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air
conditioner.

WARNING
.Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use.
. 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 under-inflated 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 injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a spare tire (if so equipped) as soon as possible. If no
tire is flat and all tires are properly
inflated, it is recommended you con-
sult an INFINITI retailer.
. For models with run-flat tires,
although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling stabi-
lity is reduced, which could lead to an
accident and personal injury. Also,
driving a long distance at high speeds
may damage the tires.
— Do not drive at speeds above 50 MPH (80 km/h) and do not drive
more than approximately 93 miles
(150 km) with a punctured run-
flat tire. The actual distance the
vehicle can be driven on a flat tire
depends on outside temperature,
vehicle load, road conditions and
other factors.
— If you detect any unusual sounds or vibrations while driving with a
punctured run-flat tire, pull off
the road to a safe location and
stop the vehicle as soon as possi-
ble. The tire may be seriously
damaged and need to be replaced.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
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
.The TPMS may not function properly
when the wheels are equipped with
tire chains or the wheels are buried in
snow.
. Do not place metalized film or any
metal parts (antenna, etc.) on the
windows. This may cause poor recep-
tion of the signals from the tire
pressure sensors, and the TPMS will
not function properly.

WARNING
Failure to follow the warnings and
instructions for proper use of the BSW
system could result in serious injury or
death.
. The BSW system is not a replacement
for proper driving procedure and is
not designed to prevent contact with
vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the
direction your vehicle will move to
ensure it is safe to change lanes.
Never rely solely on the BSW system.
. There is a limitation to the detection
capability of the radar. Not every
moving object or vehicle will be
detected. Using the BSW system
under some road, ground, lane mar-
ker, traffic or weather conditions
could lead to improper system opera-
tion. Always rely on your own opera-
tion to avoid accidents.
The BSW system helps alert the driver of
other vehicles in adjacent lanes when chan-
ging lanes.
