2001 NISSAN XTERRA check engine

for smooth operation and make sure it has
the proper distance under it when de-
pressed fully. Check the brake booster func-
tion. Be certain to keep the floor mat away
from the pedal.
Parking brake*Check that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill
with only the parking brake applied.
Automatic transmission P (Park) posi-
tion mechanismCheck that the lock re-
lease button on the selector lever operates
properly and smoothly. On a fairly steep hill
check that your vehicle is held securely with
the selector lever in the P position without
applying any brakes.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (e.g., each time you
check the engine oil or refuel).
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself operations'' section.
Windshield washer fluid*Check that there
is adequate fluid in the reservoir.
Engine oil level*Check the level afterparking the vehicle on a level surface with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Brake and clutch fluid levels*Make sure
that the brake and clutch fluid level is be-
tween the MIN and MAX lines on the reser-
voir.
Power steering fluid level* and lines
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.
UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.

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 clogged
more 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 andconnections 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.
Chassis and body maintenance
Brake lines and cablesCheck the brake
lines and hoses (including brake booster
vacuum hoses, connections & check valve)
and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.

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, 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 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.

4) Connect the tow harness connector
(SAE J1239) to your trailer.
5) Confirm proper vehicle and trailer
stop/turn lamp operation.
6) When towing is completed, disconnect
the tow harness from the trailer and the
vehicle. Store the tow harness in the
glove box. Reinstall the connector cap to
the vehicle harness.
If you need further assistance in wiring
a trailer to your NISSAN, contact an autho-
rized NISSAN dealer.
Always confirm proper vehicle and
trailer stop/turn lamp operation every
time the trailer light circuits are con-
nected for use.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and that it is prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
OBe certain your vehicle maintains a level
position when a loaded and/or unloaded
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 condi-
tion.
OAlways secure items in the trailer to
prevent load shift while driving.
OBe certain your outside mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for towing
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.
OAlways secure items in the trailer to
prevent load shift while driving.
O
Avoid abrupt starts, acceleration or stops.
OAvoid sharp turns or lane changes.
OAlways drive your vehicle at a moderate
speed.
OAlways 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 park-
ing brake, and then move the transmis-
sion 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.
OWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and
reduce speed to reduce chances of en-
gine 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).
OIf 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-
