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 un-
knowingly activate switches or controls
and inadvertently become involved in a
serious accident and injure themselves.
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.
•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 condi-
tioning controls while driving so that
full attention may be given to vehicle
operation.
The heater and air conditioner operate when
the engine is running. The air blower will op-
erate even if the engine is turned off and the
ignition switch is in the ON position.NOTE
•Condensation forms inside the air condi-
tioning unit when the air conditioner (if
equipped) is running, and is safely dis-
charged underneath your vehicle.
Traces of water on the ground are there-
fore normal.
•Odors from inside and outside the vehicle
can build up in the air conditioner unit.
Odor can enter the passenger compart-
ment through the ventilators.
When parking, set the heater and air con-
ditioner controls to turn off air recircula-
tion to allow fresh air into the passenger
compartment. This should help reduce
odors inside the vehicle.
Observe the settings recommended on the
following pages. The windows could other-
wise 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 dehumidifi-
cation function.
•Switch on the windshield demisting func-
tion briefly, if required.The air-conditioning system/automatic cli-
mate control regulates the temperature and
the humidity of the vehicle interior and filters
undesirable substances from the air.
The air-conditioning system/automatic cli-
mate 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 dur-
ing 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 par-
ticles of dust and soot and completely fil-
ters out pollen. With automatic climate
control, gaseous pollutants and odors will
also be reduced. A clogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason, you should always
observe the interval for replacing the filter,
which is specified in the Service Booklet.
As this depends on environmental condi-
tions, for example heavy air pollution, the
interval may be shorter than stated in the
Service Booklet.

side temperatures below approximately
45° F (7°C).
•After approximately five minutes if the
"Cooling with air dehumidification" func-
tion is deactivated.
•After approximately 30 minutes at outside
temperatures above approximately 45° F
(7°C) if the cooling with air dehumidifica-
tion function is activated.
SERVICING AIR CONDITIONER
WARNING
The air conditioner system contains refrig-
erant under high pressure. To avoid per-
sonal injury, 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
conditioner. Using improper refrigerants or
lubricants will cause severe damage to the air
conditioner system. (See "Air conditioner sys-
tem refrigerant and oil recommendations".)
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 ef-
ficiently, replace the filter in accordance with
the specified maintenance intervals listed in
the separate maintenance booklet. It is rec-
ommended 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 con-
ditioner.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. 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
engine is hot. Always turn off the engine
and wait until it cools down.
•If you must work with the engine run-
ning, 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 vehicle.
•If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
•Never get under the vehicle while it is
supported by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•Your vehicle is equipped with an auto-
matic 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 disconnect 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 transmis-
sion related component harness connec-
tor disconnected 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
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle 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 af-
fect 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
factory with a high-quality, year-round,
antifreeze coolant solution. The antifreeze
solution contains rust and corrosion inhibi-
tors, therefore additional cooling system
additives are not necessary.
•Never remove the radiator or coolant
reservoir 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 additional information on
precautions, refer to "If your vehicle
overheats"
•The engine coolant reservoir tank is
equipped with a pressure type cap. To
prevent 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 dam-
age to the engine, transmission and/or
cooling system.NIC2833

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
detergent. 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 deter-
gent. Then rinse the blade with clear water. If
the windshield or rear window is still not clear
after cleaning the blades and using the wiper,
replace the blades.
CAUTION
Worn windshield wiper blades can damage
the windshield and impair driver vision.

air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes
are evident, check for the cause and have it
corrected immediately.
Radiator and hoses:
Check the front of the radiator and clean off
any dirt, insects, leaves, etc., that may have
accumulated. Make sure the hoses have no
cracks, deformation, rot or loose connec-
tions.
Underbody:
The underbody is frequently exposed to cor-
rosive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust will
form on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information, see
"Cleaning exterior".
Windshield washer fluid*:
Check that there is adequate fluid in the res-
ervoir.The following descriptions are provided to
give you a better understanding of the sched-
uled maintenance items that should be regu-
larly checked or replaced. The maintenance
schedule indicates at which mileage/time in-
tervals each item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer to
"General maintenance" in this section.
Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You
are not required to perform maintenance on
these items in order to maintain the warran-
ties which come with your vehicle. Other
maintenance items and intervals are required.
When applicable, additional information can
be found in the “Do-it-yourself” section in
Chapter 8.
NOTE
INFINITI does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on an INFINITI product.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been vali-
dated by INFINITI.For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to "Recom-
mended fluids/lubricants and capacities".
EMISSION CONTROL SYSTEM
MAINTENANCE
Drive belts*:
Check engine drive belts for wear, fraying or
cracking and for proper tension. Replace any
damaged drive belts
Engine air filter*:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
check/replace the filter more frequently.
Engine coolant*:
Replace coolant at the specified interval.
When adding or replacing coolant, be sure to
use only Genuine INFINITI Engine Coolant or
equivalent in its quality (BASF Glysantin®
G40®). (For additional information, refer to

Information about service
Resetting the maintenance service interval
display:
CAUTION
If the maintenance service interval display
has been inadvertently reset, this setting
can be corrected at an INFINITI retailer.
Have service work carried out as described
in the Maintenance Schedule. This may
otherwise lead to increased wear and dam-
age to the major assemblies or the vehicle.
An INFINITI retailer will reset the mainte-
nance service interval display after the service
work has been carried out. You can also ob-
tain 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 interme-
diate stops
•If the vehicle is primarily used to travel
short distance
•For frequent operation in mountainous
terrain 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 in-
formation can be obtained at an INFINITI
retailer.
