WARNING
•The heater and air conditioner operate only
when the engine is running.
•Never leave children or adults who would
normally require the support of others alone
in the vehicle. Pets should not be left alone
either. They could unknowingly activate
switches or controls and inadvertently be-
come involved in a serious accident and in-
jure themselves. On hot, sunny days, tem-
peratures in a closed vehicle could quickly
become high enough to cause severe or
possibly fatal injuries 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.
The heater and air conditioner operate when the
engine is running. The air blower will operate
even if the engine is turned off and the ignition
switch is in the ON position. NOTE
•Condensation forms inside the air condition-
ing unit when the air conditioner (if
equipped) is running, and is safely dis-
charged underneath your vehicle.
Traces of water on the ground are therefore
normal.
•Odors from inside and outside the vehicle
can build up in the air conditioner unit. Odor
can enter the passenger compartment
through the ventilators.
When parking, set the heater and air condi-
tioner controls to turn off air recirculation to
allow fresh air into the passenger compart-
ment. This should help reduce odors inside
the vehicle.
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up. To prevent the windows from misting
up
•Switch off climate control only briefly.
•Switch on air-recirculation mode only briefly.
•Switch on the cooling with air dehumidifica-
tion function.
•Switch on the windshield demisting function
briefly, if required. The air-conditioning system/automatic climate
control regulates the temperature and the hu-
midity of the vehicle interior and filters unde-
sirable substances from the air.
The air-conditioning system/automatic climate
control can only be operated when the engine is
running. Optimum operation is only achieved
with the side windows closed.
Always keep the ventilation flaps behind the
side panelling clear. Otherwise the vehicle will
not be ventilated correctly.
NOTE
•Ventilate the vehicle for a brief period during
warm weather. This will speed up the cooling
process and the desired interior temperature
will be reached more quickly.
•The integrated filter filters out most particles
of dust and soot and completely filters out
pollen. With automatic climate control, gas-
eous pollutants and odors will also be re-
duced. A clogged filter reduces the amount
of air supplied to the vehicle interior. For this
reason, you should always observe the inter-
val for replacing the filter, which is specified
in the Service Booklet. As this depends on
environmental conditions, e.g. heavy air pol-
lution, the interval may be shorter than
stated in the Service Booklet.

If you activate air-recirculation mode, the win-
dows can mist up more quickly, in particular at
low temperatures. Only use air recirculation
mode briefly to prevent the windows misting
up.
Activating air recirculation mode
:
Make sure the ignition switch is in the ON
position.
Press the
button. The indicator light in
thebutton lights up.
Air-recirculation mode is activated automati-
cally at high outside temperatures or high
levels of pollution. When air-recirculation mode
is activated automatically, the indicator light in
the
button is not lit. Outside air is added
after about 30 minutes.
Deactivating air recirculation mode
:
Press thebutton. The indicator light in
thebutton goes out.
NOTE
Air-recirculation mode is deactivated automati-
cally:
•After approximately five minutes at outside
temperatures below approximately 45oF
(7oC).
•After approximately five minutes if the Cool-
ing with air dehumidification function is
deactivated.
•After approximately 30 minutes at outside
temperatures above approximately 45oF
(7oC) if the cooling with air dehumidification
function is activated.
SERVICING AIR CONDITIONER
WARNING
The air conditioner system contains refriger-
ant under high pressure. To avoid personal in-
jury, any air conditioner service should be
done only by an experienced technician 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.
Special charging equipment and lubricant are
required when servicing your vehicle’s air con-
ditioner. Using improper refrigerants or lubri-
cants will cause severe damage to the air
conditioner system. (See Air conditioner sys-tem refrigerant and oil recommendations
in the
9. Maintenance and Schedules section.)
An INFINITI retailer will be able to service your
environmentally friendly air conditioner system.
Air conditioner filter
The air conditioner system is equipped with an
air conditioner filter. To make sure the air
conditioner heats, defogs, and ventilates effi-
ciently, replace the filter in accordance with the
specified maintenance intervals listed in the
separate maintenance booklet. It is recom-
mended 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 condi-
tioner.

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
•Park the vehicle on a level surface, apply the
parking brake securely and block the
wheels to prevent the vehicle from moving.
Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the en-
gine is hot. Always turn off the engine and
wait until it cools down.
•If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts.
•It is advisable to secure or remove any loose
clothing and any jewelry, such as rings,
watches, etc. before working on your ve-
hicle.
•If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to es-
cape.
•Never get under the vehicle while it is sup-
ported by a jack.
•Keep smoking materials, flame and sparks
away from fuel and the battery.
•Never connect or disconnect either the bat-
tery or any transistorized component con-
nector while the ignition switch is in the ON
position.
•On gasoline engine models with the Multi-
port Fuel Injection system, the fuel filter and
fuel lines should be serviced by an INFINITI
retailer or qualified workshop because the
fuel lines are under high pressure even
when the engine is turned off.
•Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
switch is in the OFF position and the engine
is not running. To avoid injury, always dis-
connect the negative battery cable before
working near the fan.
•Always wear eye protection whenever you
work on your vehicle.
•Never leave the engine or the transmission
related component harness connector dis-
connected while the ignition switch is in the
ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle flu-
ids can hurt the environment. Always con-
form to local regulations for disposal of ve-
hicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, it is recommended you have it done by
an INFINITI retailer.

WARNING
The engine cooling system is filled at the fac-
tory with a high-quality, year-round, antifreeze
coolant solution. The antifreeze solution con-
tains rust and corrosion inhibitors, therefore
additional cooling system additives are not
necessary.
•Never remove the radiator or coolant reser-
voir cap when the engine is hot. Wait until
the engine and radiator cool down. Serious
burns could be caused by high-pressure
fluid escaping from the radiator. For addi-
tional information on precautions, refer to
If your vehicle overheats
in the6. In case
of emergency section
•The engine coolant reservoir tank is
equipped with a pressure type cap. To pre-
vent engine damage, use only a genuine
INFINITI pressure cap.
CAUTION
•Never use any cooling system additives
such as radiator sealer. Additives may clog
the cooling system and cause damage to
the engine, transmission and/or cooling
system.

Replace the spark plugs according to the main-
tenance schedule shown in a separate mainte-
nance booklet.
If replacement is required, it is recommended
that you visit an INFINITI retailer.
Always replace spark plugs with recommended
or equivalent ones.
WARNING
Be sure the engine and ignition switch are off
and that the parking brake is engaged
securely.
CAUTION
•Be sure to use the correct socket to remove
the spark plugs. An incorrect socket can
cause damage to the spark plugs.It is recommended that you visit an INFINITI
retailer if checking or replacement is required.
WARNING
•Operating the engine with the air cleaner
filter off can cause you or others to be
burned. The air cleaner filter not only cleans
the intake air, it also stops the flame if the
engine backfires. If the air cleaner is not
installed and the engine backfires, you
could be burned. Never drive with the air
cleaner filter off. Be cautious working on the
engine when the air cleaner is off.
•Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result in
serious injury.
CLEANING
If the windshield or rear window is not clear
after using the window washer or if a wiper
blade chatters when running, wax or other
material may be on the blade or windshield.
Clean the outside of the windshield or rear
window with a washer solution or a mild deter-
gent. The windshield or rear window is clean if
beads do not form when rinsing with clear
water.
Clean the blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Then
rinse the blade with clear water. If the wind-
shield or rear window is still not clear after
cleaning the blades and using the wiper, re-
place the blades.
CAUTION
Worn windshield wiper blades can damage the
windshield and impair driver vision.

has been carried out. You can also obtain
further information on maintenance work, for
example.
Special service requirements
:
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions or
increased loads, for example:
•Regular city driving with frequent intermedi-
ate stops
•If the vehicle is primarily used to travel short
distance
•For frequent operation in mountainous ter-
rain or on poor road surfaces
•If the engine is often left idling for long
periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil
filter changed more frequently. The tires must
be checked more frequently if the vehicle is
operated under increased loads. Further infor-
mation can be obtained at an INFINITI retailer.
9-8Maintenance and Schedules

The following tables show the standard maintenance schedule. Depending upon weather and atmospheric conditions, varying road surfaces, individual
driving habits and vehicle usage, additional or more frequent maintenance may be required. After 120,000 miles (192,000 km)/144 months, continue
