WARNING
●
The air conditioner cooling function oper-
ates only when the engine is running.
● Do not leave children or adults who would
normally require the support of others alone
in your vehicle. Pets should not be left alone
either. On hot, sunny days, temperatures in
a closed vehicle could quickly become high
enough to cause severe or possibly fatal in-
juries to people or animals.
● Do not use the recirculation mode for long
periods as it may cause the interior air to
become stale and the windows to fog up.
● Do not adjust the heating and air condition-
ing controls while driving so that full atten-
tion may be given to vehicle operation.
Start the engine and operate the automatic
climate control system.

OPERATING TIPS
When the engine coolant temperature and out-
side air temperature are low, the air flow from
the foot outlets may not operate. However, this
is not a malfunction. After the coolant tempera-
ture warms up, the air flow from the foot outlets
will operate normally.
The sensors
AandBlocated on the instru-
ment panel help maintain a constant tempera-
ture. Do not put anything on or around the
sensors.
IN-CABIN MICROFILTER
Models without Advanced Climate Control Sys-
tem:
The climate control system is equipped with an
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure the air conditioner
heats, defogs, and ventilates efficiently, replace
the filter in accordance with the maintenance
schedule in the INFINITI Service and Mainte-
nance Guide. To replace the filter, contact an
INFINITI retailer.
The filter should be replaced if air flow is ex-
tremely decreased or when windows fog up eas-
ily when operating heater or air conditioning
system. Models with Advanced Climate Control System:
The climate control system is equipped with a
natural grape seed polyphenol filter which col-
lects 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 maintenance schedule in
the INFINITI Service and Maintenance Guide. To
replace the filter, contact an INFINITI retailer.
The filter should be replaced if the air flow de-
creases significantly or if windows fog up easily
when operating the heater or air conditioner.SAA3088

SERVICING CLIMATE CONTROL
The climate control system in your INFINITI 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 INFINITI air conditioner.
Using improper refrigerants or lubricants will
cause severe damage to your climate control
system. (See “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section for climate con-
trol system refrigerant and lubricant recommen-
dations.)
Your INFINITI retailer will be able to service your
environmentally friendly climate control sys-
tem.
WARNING
The system contains refrigerant under high
pressure. To avoid personal injury, any air con-
ditioner service should be done only by an ex-
perienced technician with the proper
equipment.
AUDIO OPERATION PRECAUTIONS
Radio
Push the ignition switch to the ACC or ON
position and push the radio band select button
to turn on the radio. If you listen to the radio
with the engine not running, the ignition switch
should be pushed to the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external
influences. Intermittent changes in reception
quality normally are caused by these external
influences.
Using a cellular phone in or near the vehicle may
influence radio reception quality.
Radio reception :
Your INFINITI radio system is equipped with
state-of-the-art electronic circuits to enhance
radio reception. These circuits are designed to
extend reception range, and to enhance the
quality of that reception. However there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle,
even when the finest equipment is used. These
characteristics are completely normal in a given
reception area, and do not indicate any mal-
function in your INFINITI radio system.
Reception conditions will constantly change
because of vehicle movement. Buildings, ter-
rain, signal distance and interference from
other vehicles can work against ideal reception.
Described below are some of the factors that
can affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the
device in a different location may reduce or
eliminate the noise.

Your INFINITI is equipped with Bluetooth
Hands-Free Phone System. If you are an owner
of a compatible Bluetooth enabled cellular
phone, you can set up the wireless connection
between your cellular phone and the in-vehicle
phone module. With Bluetooth wireless tech-
nology, you can make or receive a telephone
call with your cellular phone in your pocket.
Once a cellular phone is connected to the
in-vehicle phone module, no phone connecting
procedure is required anymore. Your phone is
automatically connected with the in-vehicle phone module when the ignition switch is
pushed to the ON position with the registered
cellular phone turned on and carried in the
vehicle.
You can register up to 5 different Bluetooth
cellular phones in the in-vehicle phone module.
However, you can talk on only one cellular
phone at a time.
The INFINITI Voice Recognition system supports
the phone commands, so dialing a phone num-
ber using your voice is possible. For more
details, see “INFINITI VOICE RECOGNITION SYS-
TEM” later in this section; page 4-106.
Before using the Bluetooth
Hands-Free Phone
System, refer to the following notes.
● Set up the wireless connection between a
compatible cellular phone and the in-vehicle
phone module before using the Bluetooth
Hands-Free Phone System.
● Some Bluetooth enabled cellular phones
may not be recognized by the in-vehicle
phone module. Please visit
www.InfinitiUSA.com/bluetooth for a recom-
mended phone list.
● You will not be able to use a hands-free
phone under the following conditions:
– Your vehicle is outside of the telephone service area. – Your vehicle is in an area where it is
difficult to receive radio waves; such as in
a tunnel, in an underground parking ga-
rage, behind a tall building or in a moun-
tainous area.
– Your cellular phone is locked in order not to be dialed.
● When the radio wave condition is not ideal
or ambient sound is too loud, it may be
difficult to hear the other person’s voice
during a call.
● Immediately after the ignition switch is
pushed to the ON position, it may be impos-
sible to receive a call for a short period of
time.
● Do not place the cellular phone in an area
surrounded by metal or far away from the
in-vehicle phone module to prevent tone
quality degradation and wireless connection
disruption.
● While a cellular phone is connected through
the Bluetooth wireless connection, the bat-
tery power of the cellular phone may dis-
charge quicker than usual.
● If the Bluetooth Hands-Free Phone System
seems to be malfunctioning, please visit

WARNING
●Do not leave children or adults who would
normally require the support of others alone
in your vehicle. Pets should not be left alone
either. They could accidentally injure them-
selves or others through inadvertent opera-
tion of the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause severe
or possibly fatal injuries to people or
animals.
● Properly secure all cargo to help prevent it
from sliding or shifting. Do not place cargo
higher than the seatbacks. In a sudden stop
or collision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they contain
colorless and odorless carbon monoxide.
Carbon monoxide is dangerous. It can cause
unconsciousness or death.
● If you suspect that exhaust fumes are enter-
ing the vehicle, drive with all windows fully
open, and have the vehicle inspected
immediately. ●
Do not run the engine in closed spaces such
as a garage.
● Do not park the vehicle with the engine run-
ning for any extended length of time.
● Keep the lift gate closed while driving, oth-
erwise exhaust gases could be drawn into
the passenger compartment. If you must
drive with the lift gate open, follow these
precautions:
1) Open all the windows.
2) Set the
air recirculation to off and
the fan control to high to circulate the air.
● If electrical wiring or other cable connec-
tions must pass to a trailer through the seal
on the lift gate or the body, follow the manu-
facturer’s recommendation to prevent car-
bon monoxide entry into the vehicle.
● The exhaust system and body should be in-
spected by a qualified mechanic whenever:
– The vehicle is raised for service.
– You suspect that exhaust fumes are en- tering into the passenger compartment.
– You notice a change in the sound of the exhaust system. – You have had an accident involving dam-
age to the exhaust system, underbody, or
rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust system are
very hot. Keep people, animals or flammable
materials away from the exhaust system
components.
● Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
