2001 NISSAN ALTIMA ignition

of at least 87 AKI (Anti-Knock Index) num-
ber. However, you may use unleaded gaso-
line with an octane rating as low as 85 AKI
(Anti-Knock Index) number in high altitude
areas [over 4,000 ft (1,219 m)] such as:
Colorado, Montana, New Mexico, Utah,
Wyoming, northeastern Nevada, southern
Idaho, western South Dakota, western Ne-
braska, and the part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated 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, have an
authorized dealer correct the condition.
Failure to correct the condition is misuse
of the vehicle, for which NISSAN is not
responsible.
Incorrect ignition timing may result in spark
knock, after-run or overheating, which may
cause excessive fuel consumption or en-
gine damage. If any of the above symptomsare encountered, have your vehicle
checked at an authorized NISSAN dealer or
other competent service facility.
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.
