IN-CABIN MICROFILTER
Without Forest Air
®system
The climate control system is equipped
with an in-cabin microfilter which collects
dirt, pollen, dust, allergen (such as pollen,
tick shell), 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
decreases significantly or if windows fog
up easily when operating the heater or air
conditioner.
With Forest Air®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 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
decreases significantly or if windows fog
up easily when operating the heater or air
conditioner.
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 con-
sumer information ”section for climate control system refrigerant and lubricant
recommendations.)
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.

8-2Maintenance and do-it-yourself
Your new INFINITI has been designed to
have minimum maintenance requirements
with long service intervals to save you both
time and money. However, some day-to-
day and regular maintenance is essential
to maintain your INFINITI’s fine mechanical
condition, as well as its emission and
engine performance.
It is the owner ’s responsibility to make
sure that the scheduled maintenance, as
well as general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance care. You are a
vital link in the maintenance chain.
SCHEDULED MAINTENANCE
For your convenience, both required and
optional scheduled maintenance items are
describedandlistedinyour “INFINITI
Service and Maintenance Guide ”. You must
refer to that guide to ensure that necessary
maintenance is performed on your INFINITI
at regular intervals.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal
day-to-day operation. They are essential for
proper vehicle operation. It is your respon-
sibility to perform these procedures reg-
ularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and only
a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an INFINITI retailer.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced by an
INFINITI retailer.
INFINITI technicians are well-trained spe-
cialists and are kept up to date with the
latest service information through techni-
cal bulletins, service tips, and in-retailer-
ship information systems. They are
completely qualified to work on INFINITI
vehicles beforework begins.
You can be confident that an INFINITI
retailer ’s service department performs the best job to meet the maintenance require-
ments on your vehicle
—in a reliable and
economical way.

REPLACING SPARK PLUGS
If replacement is required, see an INFINITI
retailer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they
will last much longer. Follow the main-
tenance schedule in“INFINITI Service and
Maintenance Guide ”, but do not reuse
them by cleaning or regapping. Always replace spark plugs with recom-
mended or equivalent ones.SDI2549
