The high beam assist indicator light in the meter
will illuminate while the headlights are turned on.

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.

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.
