AIR FRESHENERS
Most air fresheners use a solvent that could
affect the vehicle interior. If you use an air
freshener, take the following precautions:∙ Hanging-type air fresheners can cause permanent discoloration when they con-
tact vehicle interior surfaces. Place the air
freshener in a location that allows it to
hang free and not contact an interior sur-
face.
∙ Liquid-type air fresheners typically clip on the vents. These products can cause im-
mediate damage and discoloration when
spilled on interior surfaces.
Carefully read and follow the manufacturer’s
instructions before using the air fresheners.
POWER MOONROOF (if so
equipped)
The sunshade is made from a tricot material.
CAUTION
To help prevent damaging the moonroof
while cleaning:
∙ Do not rub the material with a cloth. Do- ing so can damage the surface of the ma-
terial or cause a stain to spread.
∙ Never use benzine, thinner or any similar chemical to clean the sunshade. This may
discolor the moonroof and damage the
surface.
∙ Clean water based stains by patting the surface with a clean soft cloth dampened
in warm water. Press a clean dry cloth
onto the surface to remove as much
dampness as possible and then let air dry.
∙ Clean oil based stains by patting the sur- face with a clean soft cloth dampened in
warm water. Press a clean dry cloth onto
the surface to remove as much dampness
as possible and then let air dry.
FLOOR MATS (if so equipped)
WARNING
To avoid potential pedal interference that
may result in a collision, injury or death:
∙ NEVER place a floor mat on top of an-other floor mat in the driver front posi-
tion or install them upside down or
backwards.
∙ Use only Genuine INFINITI floor mats or equivalent floor mats, specifically de-
signed for use in your vehicle model and
model year.

FUEL RECOMMENDATION
Use unleaded premium gasoline with an oc-
tane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 87 AKI number (Research oc-
tane number 91) may be temporarily used,
but only under the following precautions:
∙ Have the fuel tank filled only partially with unleaded regular gasoline, and fill up
with unleaded premium gasoline as soon
as possible.
∙ Avoid full throttle driving and abrupt ac- celeration. Use unleaded premium gasoline for maxi-
mum vehicle performance.
CAUTION
∙ Using a fuel other than that specified
could adversely affect the emission con-
trol system, and may also affect the war-
ranty coverage.
∙ Under no circumstances should a leaded gasoline be used, because this will dam-
age the three-way catalyst. ∙ Do not use a fuel containing more than
15% ethanol in your vehicle. Your vehicle
is not designed to run on a fuel containing
more than 15% ethanol. Using a fuel con-
taining more than 15% ethanol in a ve-
hicle not specifically designed for a fuel
containing more than 15% ethanol can
adversely affect the emission control de-
vices and systems of the vehicle. Damage
caused by such fuel is not covered by the
INFINITI New Vehicle Limited Warranty.

ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure sat-
isfactory engine life and performance. For
additional information, refer to "Recom-
mended fluids/lubricants and capacities" in
this section. INFINITI recommends the use of
an energy conserving oil in order to improve
fuel economy.
Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification orInternational Lubricant Standardization and
Approval Committee (ILSAC) certification
and SAE viscosity standard. These oils have
the API certification mark on the front of the
container. Oils which do not have the speci-
fied quality label should not be used as they
could cause engine damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant to select the engine oil viscosity based on
the temperatures at which the vehicle will be
operated before the next oil change. Choos-
ing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new INFINITI vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN 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.
LTI2061
10-6Technical and consumer information

CAUTION
Damage to engine caused by improper
maintenance or use of incorrect oil and fil-
ter quality and/or viscosity is not covered
by the 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 ve-
hicle.
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
∙ towing a trailer
∙ stop and go commuting
For additional information on maintenance
schedules, refer to the “Maintenance and
schedules” section of this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFC-134a (R-134a) and the oil, Genuine
NISSAN A/C System Oil Type ND-OIL8 or
the exact equivalents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle does not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
government regulations require the recovery
and recycling of any refrigerant during auto-
motive air conditioner system service. An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant.
It is recommended that you visit an INFINITI
retailer when servicing your air conditioner
system.
