2000 NISSAN FRONTIER ignition

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the shift lever
to P (Park).
IBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
INever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
INever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts, and any other moving
parts.
IIt is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.,
before working on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel tank and bat-
tery.
IOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should
beserviced by an authorized NISSANdealer because the fuellines are un-
der high pressure even when the
engine is off.
CAUTION
IDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
INever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
IAvoid contact with used engine oil.
Improperly disposed engine oil and/
or other vehicle fluids can damage
the environment. Always conform to
local regulations for disposal of ve-
hicle fluid.
This ``Do-it-yourself'' section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.

WARNING
Be sure the ignition key is OFF or LOCK
position. The engine could rotate unex-
pectedly.
1. Visually inspect each belt for signs of
unusual wear, cuts, fraying or looseness.
If the belt is in poor condition or loose,
have it replaced or adjusted by an autho-
rized NISSAN dealer.
2. Have the belts checked regularly for con-
dition and tension in accordance with the
maintenance schedule found in the
``Maintenance'' section of this manual.

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 to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
Platinum-tipped spark plugs
It is not necessary to replace platinum-
tipped spark plugs as frequently as conven-
tional type spark plugs because they last
much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping.
IAlways replace spark plugs with rec-
commended or equivalent ones.

CAUTION
Never use a fuse of a higher amperage
rating than specified on the fuse box
cover. This could damage the electrical
system or cause a fire.
If the electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition key and the headlight
switch are OFF.
2. Remove the fuse box cover.3. Remove the fuse with the fuse puller.
4. If the fuse is open, replace it with a new
fuse.
5. If a new fuse opens again, have the
electrical system checked and repaired
by an authorized NISSAN dealer.

Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index). How-
ever, you may use unleaded gasoline with
an octane rating as low as 85 AKI 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 NIS-
SAN dealer correct the condition. Failure
to correct the condition is misuse of the
vehicle, for which NISSAN is not respon-
sible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, whichmay cause excessive fuel consumption or
engine damage. If any of the above symp-
toms are encountered, have your vehicle
checked at an authorized NISSAN dealer.
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.
