Instruments and controls2-25

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.
HEATER AND AIR CONDITIONER

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.

kg-m)
As soon as possible, tighten the wheel bolts to
the specified torque with a torque wrench.
The wheel bolts must be kept tightened to
specification at all times. It is recommended
that the wheel bolts be tightened to specifica-
tion at each maintenance interval.
Adjust the tire pressure to the COLD pressure.
COLD pressure is the tire pressure as measured
after the vehicle has been parked for three
hours or more or driven for less than 1 mile (1.6
km).
COLD tire pressures are shown on the tire and
loading information label affixed to the driver’s
side center pillar.
Wheel lock bolts (if equipped)
In order to prevent theft, the specially designed
wheel lock bolt is installed to each wheel. The
wheel lock bolt cannot be removed with the
commonly used tools. When removing tires, use the lock key provided
with your vehicle.
Removing the wheel lock bolt
:
1. Insert the wheel lock key1to the wheel
lock bolt.
2. To remove the wheel lock bolt, turn the wheel lock key counterclockwise using the
wheel wrench.
CAUTION
•Do not use a power tool to remove the wheel
lock bolts.
•When installing the wheel, tighten the
wheel lock bolts to the same tightening
torque as the normal wheel bolts. For de-
tails, see Installing the wheel earlier in
this section. NOTE
•The wheel lock bolt has an individual code. A
wheel lock key with other than the individual
code cannot remove the wheel lock bolt. If
you lose the wheel lock key, it is recom-
mended you contact an INFINITI retailer for a
duplicate with the original wheel lock key
code.
•Record the key number and keep it in a safe
place, not in the vehicle.
•When you ask for a service at an INFINITI
retailer, make sure to keep the lock key in
the vehicle. Otherwise, wheels cannot be
removed and the service cannot be per-
formed.

In case of emergency6-9

some tire damage may not be obvious. Re-
place the tires as necessary to prevent tire
failure and possible personal injury.
•Improper service of the spare tire may result
in serious personal injury. If it is necessary
to repair the spare tire, it is recommended
that you visit an INFINITI retailer for this
service.
•For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the Warranty Information Booklet.
Tires should be periodically inspected for wear,
cracking, bulging or objects caught in the tread.
If excessive wear, cracks, bulging or deep cuts
are found, the tire should be replaced immedi-
ately.
The original tires have a built-in tread wear
indicator. When the wear indicator is visible,
the tire should be replaced.
Improper servicing of a tire may result in seri-
ous personal injury. If it is necessary to repair a
tire, it is recommended you contact an INFINITI
retailer.
TIRE ROTATION
INFINITI recommends rotating the tires every
5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer to Flat tirein the6. In case
of emergency section.As soon as possible,
tighten the wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 96 ft-lb (130 N·m)
The wheel nuts must be kept tightened to speci-
fications at all times. It is recommended that
wheel nuts be tightened to specification at each
tire rotation interval.
WARNING
•After rotating the tires, check and adjust the
tire pressure.
•Do not include the spare tire in the tire rota-
tion.
•For additional information regarding tires,
refer to Important Tire Safety Information
(US) or Tire Safety Information in the War-
ranty Information Booklet.
REPLACING WHEELS AND TIRES
WARNING
Do not install a deformed wheel or tire even if it
has been repaired. Such wheels or tires could
have structural damage and could fail without
warning.
When replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. (See Wheels and Tires in the
9. Maintenance and Schedules section for
recommended types and sizes of tires and
wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to decreased
braking efficiency and/or early brake pad/shoe
wear.
8-32Do-it-yourself

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 essential
if your vehicle is to continue to operate prop-
erly. 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 prefer,
an INFINITI retailer.
SCHEDULED MAINTENANCE
The maintenance items listed underMainte-
nance schedules later in this section are re-
quired to be serviced at regular intervals. How-
ever under severe driving conditions, additional
or more frequent maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your ve-
hicle appears to malfunction, have the systems
checked and serviced. It is recommended you
visit an INFINITI retailer for this service.
INFINITI technicians are well-trained specialists
and are kept up to date with the latest service
information through technical bulletins, service
tips and training programs. They are completely
qualified to work on INFINITI vehicles before
work begins.
You can be confident that an INFINITI retailer’s
service department can perform the service
needed to meet the maintenance requirements
on your vehicle. During normal day-to-day operation of the ve-
hicle, 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

9-2Maintenance and Schedules

Exhaust system:
Make sure there are no loose supports, cracks
or holes. If the sound of the exhaust seems
unusual or there is a smell of exhaust fumes,
immediately have the exhaust system in-
spected. It is recommended you visit an INFINITI
retailer for this service. SeePrecautions when
starting and driving in the5. 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 evi-
dent, 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 accu-
mulated. Make sure the hoses have no cracks,
deformation, rot or loose connections. Underbody
:
The underbody is frequently exposed to corro-
sive 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 accumu-
late. For additional information, see
Cleaning
exterior in the7. Appearance and care sec-
tion.
Windshield washer fluid*
:
Check that there is adequate fluid in the reser-
voir. The following descriptions are provided to give
you a better understanding of the scheduled
maintenance items that should be regularly
checked or replaced. The maintenance schedule
indicates at which mileage/time intervals 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 warranties 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 Chap-
ter 8.
NOTE
INFINITI does not advocate the use of non-OEM
approved aftermarket flushing systems and
strongly advises against performing these ser-
vices on an INFINITI product. Many of the after-
market flushing systems use non-OEM approved
chemicals or solvents, the use of which has not
been validated by INFINITI.

ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING SYSTEMS
Additional maintenance items for severe oper-
ating conditions; should be performed on ve-
hicles that are driven under especially demand-
ing conditions. Additional maintenance items
should be performed if you primarily operate
your vehicle under the following conditions:
•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 Oil

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.
