WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect socket
can damage the spark plugs.
If replacement is required, it is recommended that
you visit an INFINITI retailer for this service.
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 en-
gine 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.
To remove the filter from the air cleaner, push the
tabs
Aand pull the cover upward.
The viscous paper type filter element should not
be cleaned and reused. Replace the air filter
according to the maintenance log shown in the
“INFINITI Service and Maintenance Guide.”
When replacing the air filter, wipe the inside of
the air cleaner housing and the cover with a damp
cloth.
NOTE:
After installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the clips
A.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry of air-
borne dust and pollen particles and reduces
some objectionable outside odors. The filter is
located behind the glove box. Refer to the
“INFINITI Service and Maintenance Guide” for
change intervals.
If replacement is required, it is recommended that
you visit an INFINITI retailer for this service.

FUEL RECOMMENDATION
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 gaso-
line is not available, you may use unleaded regular
gasoline with an octane rating of at least 87 AKI
number (Research 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 system, and may also affect the
warranty coverage.
● Under no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
● Do not use E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed to
run on E-15 E-85 fuel. Using E-15 or E-85
fuel in a vehicle not specifically de-
signed for E-15 or E-85 fuel can ad-
versely affect the emission control de-
vices and systems of the vehicle.
Damage caused by such fuel is not cov-
ered by the INFINITI New Vehicle Lim-
ited Warranty. ●
Do not use fuel that contains the octane
booster methylcyclopentadienyl man-
ganese tricarbonyl (MMT) . Using fuel
containing MMT may adversely affect
vehicle performance and vehicle emis-
sions. Not all fuel dispensers are la-
beled to indicate MMT content, so you
may have to consult your gasoline re-
tailer for more details. Note that Fed-
eral and California laws prohibit the use
of MMT in reformulated gasoline.
● U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.
Gasoline specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-
cations where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission control system and vehicle
performance. Ask your service station manager if
the gasoline meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. INFINITI
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing oxy-
genates such as ethanol, MTBE and methanol with
or without advertising their presence. INFINITI
does not recommend the use of fuels of which the
oxygenate content and the fuel compatibility 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 problems
and/or fuel system damage.
● The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
● If an oxygenate-blend other than
methanol blend is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
9-4Technical and consumer information
●E-15 fuel contains more than 10% oxy-
genate. E-15 fuel will adversely affect
the emission control devices and sys-
tems of the vehicle and should not be
used. Damage caused by such fuel is
not covered by the INFINITI New Ve-
hicle Limited Warranty.
● If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol) . It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not avail-
able to ensure that all methanol blends
are suitable for use in INFINITI ve-
hicles.
If any driveability problems such as engine stall-
ing and difficult hot-starting are experienced after
using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with a
low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.E–15 fuel
E-15 fuel is a mixture of approximately 15% fuel
ethanol and 85% unleaded gasoline. E-15 can
only be used in vehicles designed to run on E-15
fuel. Do not use E-15 in your vehicle. U.S. gov-
ernment regulations require fuel ethanol dispens-
ing pumps to be identified with small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
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 in your vehicle. U.S. government
regulations require fuel 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.
Fuel containing MMT
MMT, or methylcyclopentadienyl manganese tri-
carbonyl, is an octane boosting additive. NISSAN
does not recommend the use of fuel containing
MMT. Such fuel may adversely affect vehicle per-
formance, including the emissions control sys-
tem. Note that while some fuel pumps label MMT
content, not all do, so you may have to consult
your gasoline retailer for more details.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
Many of these additives intended for gum, varnish
or deposit removal may contain active solvents 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 can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, 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 on level
roads, it is recommended that you have an
INFINITI retailer correct the condition. Fail-
ure to correct the condition is misuse of the
vehicle, for which INFINITI is not respon-
sible.
Technical and consumer information9-5
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked. It is rec-
ommended that you visit an INFINITI retailer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
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 satisfactory
engine life and performance. For additional infor-
mation, refer toRecommended fluids/lubricants
and capacities in this section. INFINITI recom-
mends 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 vis-
cosity 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 ad-
ditives. 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.

9-6Technical and consumer information
When planning to drive your INFINITI ve-
hicle in another country,you should first find
out if the fuel available is suitable for your vehi-
cle’s engine.
Using fuel with an octane rating that is too low
may cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline. There-
fore, avoid taking your vehicle to areas where
appropriate fuel is not available.
When transferring the registration of your
vehicle to another country, state, province
or district, it may be necessary to modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle emis-
sion control and safety standards vary according
to the country, state, province or district; there-
fore, vehicle specifications may differ.
When any vehicle is to be taken into an-
other country, state, province or district and
registered, its modifications, transporta-
tion, and registration are the responsibility
of the user. INFINITI is not responsible for
any inconvenience that may result.

3. After the wheel blocks are in place, slowlyrelease the brake pedal until the blocks ab-
sorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Turn off the engine.
To drive away: 1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks. ●
While going downhill, the weight of the trailer
pushing on the tow vehicle may decrease
overall stability. Therefore, to maintain ad-
equate control, reduce your speed and shift to
a lower gear. Avoid long or repeated use of the
brakes when descending a hill, as this re-
duces their effectiveness and could cause
overheating. Shifting to a lower gear instead
provides “engine braking” and reduces the
need to brake as frequently.
● If the engine coolant temperature rises to a
high temperature, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this owner’s manual.
● Trailer towing requires more fuel than normal
circumstances.
● Avoid towing a trailer for your vehicle’s first
500 miles (805 km) .
● For the first 500 miles (805 km) that you do
tow, do not drive over 50 mph (80 km/h).
● Have your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “INFINITI Ser-
vice and Maintenance Guide”.
● When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
● Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. Do the following if the trailer begins to sway:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the ve-
hicle
– Do not correct trailer sway by steering or applying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of the road in a
safe area.
3. Try to rearrange the trailer load so it is bal- anced as described in this section.
● Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Downshift the transmission to a lower gear
for engine braking when driving down steep
or long hills. This will help slow the vehicle
without applying the brakes.
● Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
