Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
Be sure to use the correct wrench to
remove the plugs. An incorrect wrench
can cause damage.
SPARK PLUG REPLACEMENT

Z01.2.1/A32-DX
1. Remove the rocker cover ornament using a
suitable hexagon wrench. (Front side)
2. Disconnect the electrical connectors.
3. Loosen the ignition coil fixing bolts. And
remove the ignition coil to give access to
the spark plugs.
4. Remove the spark plugs with a spark plug
wrench.
The plug wrench has a rubber seal that
holds the spark plug so that it will not fall
when it is pulled out. Make sure that each
spark plug is snugly fitted into the plug
wrench.5. Fit the new plugs, one at a time, into the
spark plug wrench and install them. Turn
each plug in several full turns by hand, then
tighten with a spark plug wrench to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 to 22 ft-lb
(20 to 29 )6. Holding the ignition coil, re-connect each
ignition coil to its proper spark plug by
pushing it on until you feel a snap.
7. Tighten all ignition coils.

Check the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) re-
mains the same from one pedal application
to the next, continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a
little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradu-
ally with each depression as the vacuum is
released from the booster.
If the brakes do not operate properly, see your
NISSAN dealer.Press the pedal by hand and be sure the free
travel is within the limits shown above. If free
travel is too little or too much, see your NIS-
SAN dealer.
Engine compartment
If the electrical equipment does not come on,
check for a burned-out fuse.
1. Be sure the ignition key and headlight
switch are ªOFFº.
2. Open the engine hood.
3. Remove the fusible link cover.
4. Remove the fuse with the fuse puller.
5. If the fuse is burned out, replace it with a
new fuse.

Never use a fuse of higher amperage rating
than that specified on the fuse box cover.
6. If a new fuse burns out again, have the
electrical system checked and repaired by
your NISSAN dealer.

If any electrical equipment does not operate,
check for a burned-out fuse.
1. Be sure the ignition key and headlight
switch are ªOFFº.
2. Open the fuse box lid.

Nissan supports efforts towards cleaner air
and suggests that you use reformulated gaso-
line when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their pres-
ence.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage of
such fuels may cause vehicle performance
problems and/or fuel system damage.
IThe fuel should be unleaded and have
an octane rating no lower than that rec-
ommended for unleaded gasoline.
IIf an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
IIf a methanol blend is used, it should
contain no more than 5% methanol (me-
thyl alcohol, wood alcohol). It should
also contain a suitable amount of appro-
priate cosolvents and corrosion inhibi-
tors. If not properly formulated with ap-
propriate cosolvents and corrosion
inhibitors, such methanol blends maycause fuel system damage and/or ve-
hicle performance problems. At this
time, sufficient data is not available to
ensure that all methanol blends are suit-
able for use in Nissan vehicles.
If any undesirable driveability problems such
as engine stalling and hard hot starting are
experienced after using oxygenate-blend fu-
els, immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
Aftermarket fuel additives
Nissan does not recommend the use of any
fuel additives (i.e. fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvent or similar
ingredients that can be harmful to the fuel
system and engine.
Octane rating tips
In most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 87 or 91 AKI (Anti-Knock Index) number.
However, you may use unleaded gasoline with
an octane rating as low as 85 AKI (Anti-KnockIndex) number in these high altitude areas
[over 4,000 ft (1,219 m)] such as: Colorado,
Montana, New Mexico, Utah, Wyoming, north-
eastern 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 ªspark knockº. (ªSpark
knockº 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 encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.
However, now and then you may notice
light spark knock for a short time while
