level roads, it is recommended you have an
INFINITI retailer correct the condition. Failure to
correct the condition is misuse of the vehicle, for
which INFINITI is not responsible.
Incorrect ignition timing will result in knocking,
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 vehicle checked. It is
recommended 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 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 addi-
tional information, refer toRecommended
fluids/lubricants and capacitiesearlier 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 ApprovalCommittee (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 INFINITI oil filter. When replac-
ing, it is recommended you 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. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals could reduce 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 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 recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle.
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
•Stop and go “rush hour” traffic
Refer to the “INFINITI Service and Maintenance
Guide” for the maintenance schedule.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system of your vehicle must
be charged with the refrigerant HFC-134a and
the lubricant INFINITI A/C System Oil Type S or
the exact equivalents.
CAUTION
The use of any other refrigerant or oil may
cause severe damage to the air conditioning
system and will require the replacement of all
air conditioner system components.
The refrigerant HFC-134a in your vehicle will not
harm the Earth’s ozone layer. However, it may
contribute in a small part to the global warming
effect.
Certain government regulations require the re-
covery and recycling of any refrigerant during
automotive 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 sys-
tem.
