WARNING
The engine cooling system is filled at the
factory with a high-quality, year-round,
antifreeze coolant solution. The antifreeze
solution contains rust and corrosion inhibi-
tors, therefore additional cooling system
additives are not necessary.
•Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high-pressure fluid escaping from the
radiator. For additional information on
precautions, refer to "If your vehicle
overheats"
•The engine coolant reservoir tank is
equipped with a pressure type cap. To
prevent engine damage, use only a
genuine INFINITI pressure cap.
CAUTION
•Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.NIC2833

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".
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.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been vali-
dated by INFINITI.For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to "Recom-
mended fluids/lubricants and capacities".
EMISSION CONTROL SYSTEM
MAINTENANCE
Drive belts*:

FUEL RECOMMENDATION
INFINITI recommends the use of unleaded
premium gasoline with an octane rating of at
least 91 AKI (Anti-Knock Index) number (Re-
search octane number 95).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 89 AKI number (Research oc-
tane number 93) 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 war-
ranty coverage.
•Under no circumstances should a leaded
gasoline be used, because this will dam-
age 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 or 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 labeled
to indicate MMT content, so you may
have to consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of MMT
in reformulated 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 ap-
propriate percentage for that region.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is available.
Technical information10-3

Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel in-
jector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold com-
mercially. Many of these additives intended
for gum, varnish or deposit removal may con-
tain active solvent or similar ingredients that
can be harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rat-
ing lower than recommended above can
cause persistent, 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 on level roads, it is recom-
mended you have an INFINITI retailer cor-
rect the condition. Failure to correct the con-
dition is misuse of the vehicle, for which
INFINITI is not responsible.
Incorrect ignition timing will result in knock-
ing, after-run and/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 ve-
hicle checked. It is recommended you visit an
INFINITI retailer.However, now and then you may notice light
spark knock for a short time while accelerat-
ing 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.
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"
earlier in this section.
Select only engine oils that meet the MB229.5
specification and SAE viscosity standard. These
oils have the MB229.5 specification label on 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.
