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.

You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle
from outside. The air already inside the ve-
hicle will then be recirculated.
If you activate air-recirculation mode, the
windows can mist up more quickly, in particu-
lar at low temperatures. Only use air recircu-
lation 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 the
button. The indicator light in
thebutton goes out.
NOTE
Air-recirculation mode is deactivated auto-
matically:
•After approximately five minutes at out-
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" 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 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.

Some day-to-day and regular maintenance is
essential to maintain your vehicle’s good me-
chanical condition, as well as its emission and
engine performance.
It is the owner’s responsibility to make sure
that the specified 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.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-
to-day operation of the vehicle. They are es-
sential if your vehicle is to continue to operate
properly. It is your responsibility to perform
these procedures regularly as prescribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks and inspections can be done by
yourself, a qualified technician, or if you pre-
fer, an INFINITI retailer.
SCHEDULED MAINTENANCE
The maintenance items listed under "Mainte-
nance schedules" later in this section are re-
quired to be serviced at regular intervals.
However under severe driving conditions, ad-
ditional or more frequent maintenance will be
required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and serviced. It is recom-
mended you visit an INFINITI retailer for this
service.
INFINITI technicians are well-trained spe-
cialists and are kept up to date with the latest
service information through technical bulle-
tins, service tips and training programs. They
are completely qualified to work on INFINITI
vehiclesbeforework begins.
You can be confident that an INFINITI retail-
er’s service department can perform the ser-
vice needed to meet the maintenance re-
quirements on your vehicle. During normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations
or smells, be sure to check for the cause or
have an INFINITI retailer do it promptly. In
addition, it is recommended you notify an
INFINITI retailer if you think that repairs are
required.
When performing any checks or maintenance
work, closely observe "Explanation of general
maintenance items" later in this section.

tions when starting and driving" in the "5.
Starting and driving" section.
Fluid leaks:
Check under the vehicle for fuel, oil, water or
other fluid leaks after the vehicle has been
parked for a while. Water dripping from the
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" in the "7. Appearance and
care" section.
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.

ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
SYSTEMS
Additional maintenance items for severe op-
erating conditions; should be performed on
vehicles that are driven under especially de-
manding conditions. Additional maintenance
items should be performed if you primarily
operate your vehicle under the following con-
ditions:
•Repeated short trips of less than 5 miles in
normal temperatures or less than 10 miles
in freezing temperatures.
•Stop-and-go traffic in hot weather or low
speed driving for long distances.
•Driving in dusty conditions or on rough,
muddy or salt-spread roads.
•Towing a trailer, or using a camper or car-
top carrier.
OIL CHANGE MONITOR
This vehicle is equipped with oil change moni-
tor. It calculates engine oil and filter change
interval base on driving conditions. Driving in
severe conditions will shorten the engine oil
and filter change interval. When the Engine

Selecting the correct oil filter
Your new vehicle is equipped with a high—
quality genuine INFINITI oil filter. When re-
placing, it is recommended you use the genu-
ine 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. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals could reduce engine life. Damage to
engines caused by improper maintenance or
use of incorrect oil and filter quality and/or
viscosity is not covered by the new INFINITI
New Vehicle Limited Warranty.
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 recom-
mended 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 Mainte-
nance Guide” for the maintenance schedule.
