2011 INFINITI EX Owners Manual

●Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than the
standard tire. Replace the spare tire as soon
as the tread wear indicators appear.
● Do not use the spare tire on other vehicles.
● Do not use more than one spare tire at the
same time.
CAUTION
● Do not use tire chains on a TEMPORARY USE
ONLY spare tire. Tire chains will not fit prop-
erly and may cause damage to the vehicle.
● Because the TEMPORARY USE ONLY spare
tire is smaller than the original tire, ground
clearance is reduced. To avoid damage to the
vehicle, do not drive over obstacles. Also do
not drive the vehicle through an automatic
car wash since it may get caught.

CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS
9-2Technical and consumer information

FUEL RECOMMENDATION
VQ35HR engine
INFINITI recommends the use of unleaded pre-
mium gasoline with an octane rating of at least
91 AKI (Anti-Knock Index) number (Research
octane number 96).
If unleaded premium gasoline is not available,
you may use unleaded regular gasoline with an
octane rating of at least 87 AKI number (Re-
search octane number 91), but you may notice a
decrease in performance.
CAUTION
●Using a fuel other than that specified could
adversely affect the emission control sys-
tem, and may also affect warranty coverage.
● Under no circumstances should a leaded
gasoline be used, because this will damage
the three-way catalyst.
● Do not use E-85 fuel in your vehicle. Your
vehicle is not designed to run on E-85 fuel.
Using E-85 fuel can damage the fuel system
components and is not covered by the
INFINITI vehicle limited warranty.
Gasoline specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifica-
tions where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission system and vehicle perfor-
mance. Ask your service station manager if the
gasoline meets the World-Wide Fuel Charter
(WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
INFINITI supports efforts towards cleaner air
and suggests that you use reformulated gaso-
line when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
INFINITI does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility for your INFINITI cannot be readily
determined. If in doubt, ask your service station
manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage of such fuels may cause vehicle performance prob-
lems and/or fuel system damage.
●
The fuel should be unleaded and have an oc-
tane rating no lower than that recommended
for unleaded gasoline.
● If an oxygenate-blend, excepting a methanol
blend, is used, it should contain no more than
10% oxygenate. (MTBE may, however, be
added up to 15%.)
● If a methanol blend is used, it should contain
no more than 5% methanol (methyl alcohol,
wood alcohol). It should also contain a suit-
able amount of appropriate cosolvents and
corrosion inhibitors. If not properly formu-
lated with appropriate cosolvents and corro-
sion inhibitors, such methanol blends may
cause fuel system damage and/or vehicle
performance problems. At this time, suffi-
cient data is not available to ensure that all
methanol blends are suitable for use in
INFINITI vehicles.
If any undesirable driveability problems such as
engine stalling or hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refueling.
Gasoline containing oxygenates can cause paint
damage.
Technical and consumer information9-3

E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed onlevel roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.
CAUTION
●
Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. ●
U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
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, see “CA-
PACITIES AND RECOMMENDED
FUEL/LUBRICANTS” earlier 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 American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE viscos-
ity standard. These oils have the API certifica-
tion mark on the front of the container. Oils
which do not have the specified 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 that the engine oil viscosity be selected
based on the temperatures at which the vehicle
will be operated before the next oil change.
Choosing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When replac-
ing, use the genuine 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. Oil and filter other than
the specified quality, or oil and filter change
intervals longer than recommended could re-
duce 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 vehicle limited warranties.
Your engine was filled with a high quality
engine oil when it was built. You do not have to
STI0505
Technical and consumer information9-5

change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle. Opera-
tion under the following conditions may require
more frequent oil and filter changes.
●repeated short distance driving at cold out-
side temperatures,
● driving in dusty conditions,
● extensive idling,
● stop and go “rush hour” traffic,
Refer to the “INFINITI Service and Maintenance
Guide” for the maintenance schedule.AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioning system in your INFINITI ve-
hicle must be charged with the refrigerant HFC-
134a (R-134a) and the lubricant, NISSAN A/C sys-
tem oil Type S or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant will
cause severe damage to the air conditioning
system and will require the replacement of all
air conditioner system components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s ozone
layer. Although this refrigerant does not affect
the earth’s atmosphere, certain governmental
regulations require the recovery and recycling
of any refrigerant during automotive air condi-
tioning system service. Your INFINITI retailer
has the trained technicians and equipment
needed to recover and recycle your air condi-
tioning system refrigerant.
Contact an INFINITI retailer when servicing your
air conditioning system.
