check engine NISSAN ALTIMA 2001 L30 / 2.G Owner's Guide

Brake pedal and booster* ÐCheck the
pedal 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* ÐCheck 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 position
mechanism ÐOn a fairly steep hill check
that your vehicle is held securely with the
shift selector lever in the P (Park) position
without applying any brakes.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically, such as each time
you check the engine oil or refuel.
Additional information on the items
marked with an ª*º can be found in the
ªDo-it-yourself'' section of this manual.
Windshield washer fluid* ÐCheck that
there is adequate fluid in the tank.
Engine oil level* ÐCheck the level after
parking the vehicle on a level surface, withthe engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Brake and (if so equipped) clutch fluid
levels* ÐMake sure that the brake and
clutch fluid level are between the MIN and
MAX lines on each reservoir.
Power steering fluid level* and lines Ð
Check the level when the fluid is cold and
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Automatic transmission fluid level* Ð
Check the level after putting the shift selec-
tor lever in P (Park) with the engine idling at
operating temperature.
Engine coolant level* ÐCheck the cool-
ant level when the engine is cold.
Radiator and hoses ÐCheck 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* ÐMake sure the drive
belts are not frayed, worn, cracked or oily.
Battery* ÐCheck the fluid level in each
cell. It should be between the MAX and MIN
lines.Exhaust system ÐMake sure there are no
cracks, holes, loose joints or supports. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected by
a qualified individual. (See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.)
Underbody ÐThe 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
linesand exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, especially those
areas where mud and dirt may accumulate.
See the ``Appearance and care'' section for
additional information.
Fluid leaks ÐCheck 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 by
an authorized NISSAN dealer.

EXPLANATION OF
MAINTENANCE ITEMS
Additional information on the following
items marked with an ``*'' is found in the
``Do-it- yourself'' section of this manual.
Emission control system
maintenance
Drive belts* ÐCheck drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace any damaged drive belts.
Air cleaner filter ÐUnder normal driving
conditions, the air cleaner filter should be
replaced in accordance with the mainte-
nance schedule. However, driving the ve-
hicle in dusty areas may cause rapid clog-
ging of the element. Consequently, the
element may have to be replaced more
frequently.
EVAP vapor lines ÐCheck vapor lines
and connections for leaks, looseness or
deterioration. If leaks are found, replace
them.
Fuel lines ÐCheck the fuel hoses, piping
and connections for leaks, looseness or
deterioration. Replace any damaged parts.Fuel filter ÐIf the vehicle is operated
under extremely adverse weather condi-
tions or in areas where ambient tempera-
tures are either extremely low or extremely
high, the filter might become clogged. In
such an event, replace the filter immedi-
ately.
Engine coolant* ÐDrain and flush the
cooling system.
Engine oil & oil filter* ÐUnder 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* ÐReplace with new plugs
having the correct heat range.
Intake & exhaust valve clearance Ð
Check the valve clearance if valve noise
increases.
Chassis and body maintenance
Brake lines & cables ÐCheck 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.
Brake pads, rotors, drums & linings Ð
Check these and the other neighboring
brake components for wear, deterioration
and leaks. Under severe driving conditions,
they may have to be inspected more fre-
quently.
Manual & automatic transmission fluid*
ÐCheck the fluid level and visually inspect
for signs of leakage.
Under severe driving conditions, the fluid
should be replaced at the specified interval.
Steering gear & linkage, axle & suspen-
sion parts, and drive shaft boots Ð
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, inspection should be performed
more frequently.
Exhaust system ÐVisually check the ex-
haust pipes, muffler, and hangers for proper
attachment, leaks, cracks, chafing, abra-
sion, deterioration, etc. Under severe driv-
ing conditions, inspection should be per-
formed more frequently.

of at least 87 AKI (Anti-Knock Index) num-
ber. However, you may use unleaded gaso-
line with an octane rating as low as 85 AKI
(Anti-Knock Index) number 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 dealer correct the condition.
Failure to correct the condition is misuse
of the vehicle, for which NISSAN is not
responsible.
Incorrect ignition timing may result in spark
knock, after-run or overheating, which may
cause excessive fuel consumption or en-
gine damage. If any of the above symptomsare encountered, have your vehicle
checked at an authorized NISSAN dealer or
other competent service facility.
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.

WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe 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 pos-
sible causes of either condition.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your rear view 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.cAlways secure items in the trailer to
prevent load shift while driving.
cAvoid 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 an automatic transmis-
sion, first block the wheels and apply the
parking brake, and then move the shift
lever into the P position. If you move the
shift lever to the P position before block-
ing 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, downshift
the transmission to a lower gear and
reduce speed to reduce chances of en-
gine overloading and/or overheating.
cIf the engine coolant rises to an ex-
tremely high temperature when the airconditioner 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 the first 500
miles (800 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 compensate for
this, make a larger than normal turning
radius during the turn.
cCrosswinds and rough roads will ad-
versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be pre-
pared for possible changes in crosswinds
that could affect vehicle handling. If
swaying does occur, firmly grip the steer-
ing wheel, steer straight ahead, and im-
mediately (but gradually) reduce vehicle
