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 capacities 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 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”.

knee air bag will deflate quickly after the collision
is over OR the knee air bag will remain inflated for
a short time.
The knee air bags operate only when the
ignition switch is placed in the ON position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off a few seconds
after the engine starts if the system is op-
erational.
WARNING
●Do not place any objects between the
knee bolster and the driver’s seat. Such
objects may become dangerous projec-
tiles and cause injury if a knee air bag
inflates.
● Right after inflation, the knee air bag
system components will be hot. Do not
touch them; you may severely burn
yourself.
● No unauthorized changes should be
made to any components or wiring of
the knee air bag system. This is to pre-
vent damage to or accidental inflation
of the knee air bag system. ●
Do not make unauthorized changes to
your vehicle’s electrical system or sus-
pension system. This could affect
proper operation of the knee air bag
system.
● Tampering with the knee air bag system
may result in serious personal injury.
For example, do not change the driver
knee bolster or install additional trim
material around the knee air bag.
● It is recommended that you visit an
INFINITI retailer for work on and around
the knee air bag. It is also recom-
mended that you visit an INFINITI re-
tailer for installation of electrical equip-
ment. The SRS wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices should
not be used on the knee air bag system.
*The SRS wiring harness or connectors
are yellow or orange for easy
identification.
When selling your vehicle, we request that you
inform the buyer about the knee air bag system
and guide the buyer to the appropriate sections
in this manual.
