from the outside air circulation mode to
the recirculation mode.
When the intake air control button is
pushed under the following conditions,
the indicator light on the“
”side will
illuminate and the exhaust gas/outside
odor detecting sensor will turn on.
. The air flow control is not in the front
defroster mode (the indicator light on

and outside air circulation mode.
OPERATING TIPS
When the engine coolant temperature and
outside air temperature are low, the air
flow from the foot outlets may not operate.
This is not a malfunction. After the coolant
temperature warms up, air will flow nor-
mally from the foot outlets.

IN-CABIN MICROFILTER
To make sure that the air conditioner
heats, defogs/defrosts and ventilates effi-
ciently, replace the filter according the
specified maintenance intervals listed in
the INFINITI Service and Maintenance
Guide. 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. A natural grape seed polyphe-
nol filter (if so equipped) collects and
neutralizes dirt, pollen, dust, etc.
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” (P.9-2) for climate control sys-
tem refrigerant and lubricant recommenda-
tions.)
Your INFINITI retailer will be able to service
your environmentally friendly climate con-
trol 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.
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 trans-
mitter, buildings, 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 en-
hance radio reception. These circuits are
designed to extend reception range, and to
enhance the quality of that reception.
However there are some general character-
istics of both FM and AM radio signals that
can affect radio reception quality in a
moving vehicle, even when the finest

9-6Technical and consumer information
Oil which may contain foreign matter or
has been previously used should not be
used.
Oil viscosity
The engine oil viscosity or thickness
changes with temperature. Because of this,
it is important that the engine oil viscosity
be selected based on the temperatures at
which the vehicle will be operated before
the next oil change. Choosing an oil
viscosity other than that recommended
could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, use the genuine oil filter or its
equivalent for the reason described in
change intervals.
Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Oil and
filter other than the specified quality, or oil
and filter change intervals longer than
recommended could reduce engine life.
Damage to engines caused by improper
maintenance or use of incorrect oil andfilter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warran-
ties.
Your engine was filled with a high quality
engine oil when it was built. You do not
have to change the oil before the first
recommended change interval. Oil and
filter change intervals depend upon how
you use your vehicle. Operation under the
following conditions may require more
frequent oil and filter changes.
.
repeated short distance driving at cold
outside temperatures,
. driving in dusty conditions,
. extensive idling,
. stop and go “rush hour”traffic,
Refer to the “INFINITI Service and Main-
tenance Guide” for the maintenance sche-

FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
The air conditioning system in your
INFINITI vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN A/C system oil Type S
or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant
will cause severe damage to the air con-
ditioning system and will require the repla-
cement of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
governmental regulations require the re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.
Contact an INFINITI retailer when servicing
your air conditioning system.
