2001 NISSAN ALTIMA warning

The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance intervals shown in the ``Main-
tenance'' section of this manual. When re-
placing the filter, wipe the inside of the air
cleaner filter housing and the cover with a
damp cloth.
WARNING
cOperating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it
isn't there, and the engine backfires,
you could be burned. Do not drive
with the air cleaner removed, and be
careful when working on the engine
with the air cleaner removed.
cNever pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front (and rear, if equipped) disc-type
brakes self-adjust every time the brake
pedal is applied. The rear drum-type brakes
also self-adjust every time the brake pedal
is applied.
If the brake pedal goes down farther than
normal, it may be due to a lack of adjust-
ment of the rear drum brakes. To adjust,
apply the parking brake several times.
WARNING
See an authorized NISSAN dealer for a
brake system check if the brake pedal
height does not return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it makes a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wearindicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise from
the rear drum brakes, have them inspected
as soon as possible by an authorized
NISSAN dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance'' section of this manual.
BRAKE BOOSTER
Check the brake booster function as fol-
lows:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedalapplication 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. Keep 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 de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, see an
authorized NISSAN dealer.

If you have a flat tire, see the ``In case of
emergency'' section of this manual.
TIRE PRESSURE
Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Periodically check the tire pressure (including
the spare). Incorrect tire pressure may ad-
versely affect tire life and vehicle handling. Tire
pressure should be checked when tires are
COLD. Tires are considered COLD after the
vehicle has been parked for three or morehours, or driven less than 1 mile (1.6 km).
COLD tire pressures are shown on the tire
placard affixed to the driver's door center pillar.
WARNING
cImproperly inflated tires can fail sud-
denly and cause an accident.
c
The vehicle weight capacity is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result in
reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a seri-
ous accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
cBefore taking a long trip, or when-
ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level.
cDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed rated tires. Driving
faster than 85 MPH (140 km/h) may
result in tire failure, loss of control
and possible injury.
TYPES OF TIRES
WARNING
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., summer, all season or snow) and
construction. An authorized NISSAN
dealer may be able to help you with
information about tire type, size, speed
rating and availability. Replacement
tires may have a lower speed rating
than the factory equipped tires, and
may not match the potential maximum
vehicle speed. Never exceed the maxi-
mum speed rating of the tire.
All Season tires
NISSAN specifies All Season tires on some
models to provide good performance for
use all year around, including snowy and icy
road conditions. All Season Tires are iden-
tified by ALL SEASON and/or M&S on the
tire sidewall. Snow tires have better snow
traction than All Season tires and may be
more appropriate in some areas.

WHEELS AND TIRES
Do-it-yourself8-35
ZX

The wheel nuts must be kept tightened to
specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each rotation interval.
WARNING
cAfter rotating the tires, check and
adjust the tire pressure.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
cDo not include the spare tire in the
tire rotation.
Tire wear and damage
WARNING
cTires should be periodically in-
spected for wear, cracking, bulging,
or objects caught in the tread. If
excessive wear, cracks, bulging, or
deep cuts are found, the tire(s)
should be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire(s) should
be replaced.cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an authorized
NISSAN dealer.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. Recom-
mended types and sizes are shown in
``wheels/tire size'' in the ``Technical and con-
sumer information'' section of this manual.
WARNING
c
The use of tires other than those rec-
ommended, or the mixed use of tires
of different brands, construction (bias,
bias-belted, radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-
tire clearance, tire chain clearance,
speedometer calibration, headlight
aim and bumper height. Some of these
effects may lead to accidents and
could result in serious personal injury.

cIf the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause pre-mature tire wear, degrade
vehicle handling characteristics
and/or interference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear. Re-
fer to ``Wheel/tire size'' in the ``Techni-
cal and consumer information'' sec-
tion of this manual for wheel off-set
dimensions.
cDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have unknown
structural damage and could fail
without warning.
cThe use of retread tires is not recom-
mended.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle. Spin
balancing the front wheels on the vehicle
could lead to transmission damage.
Care of wheels
cWash the wheels when washing the ve-
hicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
cDo not use abrasive cleaners when
washing the wheels.
cInspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
cNISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire (TEMPORARY USE
ONLY spare tire)
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must
be used, otherwise your vehicle could be
damaged or involved in an accident:
WARNING
cThe spare tire should be used for
emergency use only. It should be
replaced with the standard tire at the
first opportunity to avoid possible
tire or differential damage.
cDrive carefully while the TEMPO-
RARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and
abrupt braking while driving.
cPeriodically check spare tire infla-
tion pressure. Always keep the pres-
sure of the TEMPORARY USE ONLY
spare tire at 60 psi (420 kPa, 4.2 bar).
cWith the TEMPORARY USE ONLY
spare tire installed do not drive the
vehicle at speeds faster than 50 MPH
(80 km/h).
cWhen driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on
the rear wheels and the original tire
used on the front wheels (drive
wheels). Use tire chains only on the
front (original) tires.

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,

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.
