REPLACING SPARK PLUGS
WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket toremove the spark plugs. An incorrect
socket can cause damage the spark
plugs.
Platinum-tipped spark plugsIt is not necessary to replace the platinum-
tipped spark plugs as frequently as the conven-
tional type spark plugs since they will last much
longer. Follow the maintenance schedule, but do
not reuse them by cleaning or regapping.
If replacement is required, see your NISSAN
dealer for servicing.
Always replace with recommended
platinum-tipped spark plugs.The filter element should not be cleaned and
reused as it is given a special treatment. We
recommended it be replaced according to the
maintenance log shown in a separate “Service
and Maintenance Guide”. When replacing the
filter, wipe the inside of the air cleaner housing
and the cover with a damp cloth.
WARNING

Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner

CAUTION
Never use a fuse of higher amperage
rating than that specified on the fuse
box cover. This could damage the elec-
trical system or cause a fire.
If any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition key and the headlight
switch are OFF.2. Open the engine hood.
3. Remove the fuse box cover.
4. Remove the fuse with the fuse puller.
5. If the fuse is open, replace it with a new fuse.
6. If a new fuse opens again, have the electrical
system checked and repaired by your
NISSAN dealer.
Fusible linksIf any electrical equipment does not operate and
fuses are in good condition, check the fusible
links. If any of these fusible links are melted,
replace only with genuine NISSAN parts.

which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvents or similar
ingredients that can be harmful to the fuel sys-
tem and engine.Octane rating tipsIn most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 91 AKI (Anti-Knock Index) number
(VQ35DE engine) or 87 AKI (Anti-knock Index)
number (VG33E engine). However, you may use
unleaded gasoline with an octane rating as low
as 85 AKI (Anti-Knock Index) number in these
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 Nebraska, and
that 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 se-
vere, 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 your dealer correct the condi-tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer or other competent service fa-
cility.
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.
