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 the “
” front defroster but-
ton 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.
The Plasmacluster
®icon on the Climate
screen indicates the status of the Plas-
macluster
®ion emission from the system
and changes with the amount of the air flow.

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.
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.
WINDOW ANTENNA
The antenna pattern is printed inside the 3rd
row seat window.
CAUTION
. Do not place metalized film near the
3rd row seat window or attach any
metal parts to it. This may cause poor
reception or noise.
. When cleaning the inside of the 3rd
row seat window, be careful not to
scratch or damage the 3rd row seat
window antenna. Lightly wipe along
the antenna with a dampened soft
cloth.

SATELLITE ANTENNA
There is a satellite antenna on the rear part
of the vehicle roof.When installing a car phone or a CB radio in
your vehicle, be sure to observe the follow-
ing cautions, otherwise the new equipment
may adversely affect the electronic control
modules and electronic control system har-
ness.
WARNING
.
A cellular phone should not be used
for any purpose while driving so full
attention may be given to vehicle
operation. Some jurisdictions prohibit
the use of cellular phones while
driving.
. If you must make a call while your
vehicle is in motion, the hands-free
cellular phone operational mode (if so
equipped) is highly recommended.
Exercise extreme caution at all times
so full attention may be given to
vehicle operation.
. If a conversation in a moving vehicle
requires you to take notes, pull off
the road to a safe location and stop
your vehicle before doing so.
CAUTION
.Keep the antenna as far away as
possible from the electronic control
modules.
. Keep the antenna wire more than 8 in
(20 cm) away from the electronic
control system harness. Do not route
the antenna wire next to any harness.
. Adjust the antenna standing-wave
ratio as recommended by the manu-
facturer.
. Connect the ground wire from the CB
radio chassis to the body.
. For details, it is recommended you
visit an INFINITI retailer.
CAR PHONE OR CB RADIO

6-14In case of emergency
CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle fire.
. To avoid the danger of being scalded,
never remove the radiator cap or
coolant reservoir cap while the en-
gine is still hot. When the radiator
cap or coolant reservoir cap is re-
moved, pressurized hot water will
spurt out, possibly causing serious
injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc., take the following
steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off the
engine.) Do not open the hood further
until no steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is
leaking or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time.
7. After the engine cools down, check the coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service.
