2001 NISSAN FRONTIER check engine

Maintenance for off-road driving
(
only)
Whenever you drive off-road through sand,
mud or water as deep as the wheel hub,
more frequent maintenance may be re-
quired of the following items:
¶Brake pads and rotors
¶Brake linings and drums
¶Brake lines and hoses
¶Wheel bearing grease and free-running
hub grease
¶Differential, transmission and transfer oil
¶Steering linkage
¶Propeller shafts and front drive shafts
¶Air cleaner filter
These items should be checked frequently
to assure safe and proper operation of your
vehicle.
EXPLANATION OF
MAINTENANCE ITEMS
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
Emission control system
maintenance
Drive belts*Check drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace any damaged drive belts.
Air cleaner filterUnder normal driving con-
ditions, the air cleaner filter should be re-
placed in accordance with the maintenance
schedule. However, driving the vehicle in
dusty areas may cause rapid clogging of the
element. Consequently, the element may
have to be replaced more frequently.
Positive crankcase ventilation (PCV) fil-
terUnder normal driving conditions, the
filter should be replaced in accordance with
the maintenance schedule. If the vehicle is
operated under extremely adverse weather
conditions or in areas where ambient tem-
peratures are either extremely low or ex-
tremely high, the filter may become cloggedmore rapidly. In such an event, replace the
filter immediately.
EVAP Vapor linesCheck vapor lines and
connections for leaks, looseness, or dete-
rioration. If leaks are found, replace the
lines.
Fuel linesCheck the fuel hoses, piping and
connections for leaks, looseness or deterio-
ration. Replace any damaged parts.
Fuel filterIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, the
filter might become clogged. In such an
event, replace the filter immediately.
Engine coolant*Flush and refill the cooling
system.
Engine oil and oil filter*Under normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs*Replace with new plugs hav-
ing the correct heat range.

If any driveability problems such as engine
stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) 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 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 (except supercharger) or 91
(supercharger) AKI (Anti-Knock Index).
However, for non-supercharged vehicles
only, 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]) suchas: 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, which
may 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 isno cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.

trailer is hitched. Do not drive the vehicle
if it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either con-
dition.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your outside mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for tow-
ing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability and braking performance will be
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or
stops.
cAvoid sharp turns or lane changes.cAlways drive your vehicle at a moderate
speed.
cAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with automatic transmission,
first block the wheels and apply the
parking brake, and then move the trans-
mission shift selector lever into the P
(Park) position. If you move the shift
lever to the P (Park) position before
blocking the wheels and applying the
parking brake, transmission damage
could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
However, for long steep grades, do not
stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h).
cIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn off the air
conditioner. Coolant heat can be addi-tionally vented by opening the windows,
switching the fan control to high and
setting the temperature control to the
HOT position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for your vehicle's
first 500 miles (805 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
cCrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
