2001 NISSAN ALTIMA check engine light

The brake system then operates normally,
but without anti-lock assistance.
If the light comes on during the self-test or
while driving, take the vehicle to an autho-
rized NISSAN dealer for repair.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent
accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces, but re-
member that the stopping distance on
slippery surfaces will be longer than on
normal surfaces, even with the anti-
lock brake system. Stopping distances
may also be longer on rough, gravel or
snow covered roads, or if you are using
tire chains. Always maintain a safe dis-
tance from the vehicle in front of you.
Ultimately, the responsibility for safety
of self and others rests in the hands of
the driver.
Tire type and condition of tires may
also affect braking effectiveness.cWhen replacing tires, install the
specified size of tire on all four
wheels.
cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
ªTire placardº in the ``Technical and
Consumer information'' section of
this manual.
Refer to ``Wheels and tires'' in the ``Do-
it-yourself'' section of this manual.
FREEING A FROZEN DOOR
LOCK
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it into the key hole.
ANTI-FREEZE
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check the anti-freeze (ethylene glycol base)
to assure proper winter protection. For de-
tails, see ``Engine cooling system'' in the
``Do-it-yourself'' section.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself ''
section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the

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.

CHECKING CLUTCH PEDAL
Press the pedal by hand and be sure the
free travel is within the limits shown above.
If free travel is out of the range shown
above, see an authorized NISSAN dealer.
ENGINE COMPARTMENT
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 come
on, check for an open fuse.
1. Be sure the ignition switch and the head-
light switch are OFF.
2. Open the engine hood.3. Remove the fuse box cover.
4. Remove the fuse with the fuse puller
located in the passenger compartment
fuse box.
5. If the fuse is open, replace it with a new
fuse.
6. If a new fuse also opens, have the elec-
trical system checked and repaired by an
authorized NISSAN dealer.
Fusible links
If the electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace only with genuine NISSAN
parts.ADIO528ADI1021

cluding the spare, and adjust to the speci-
fied pressure if necessary. Check carefully
for damage, cuts or excessive wear.
Wheel nuts* ÐWhen checking the tires,
make sure no wheel nuts are missing, and
check for any loose wheel nuts. Tighten if
necessary.
Tire rotation* ÐTires should be rotated
every 7,500 miles (12,000 km).
Wheel alignment and balance ÐIf the
vehicle should pull to either side while driv-
ing on a straight and level road, or if you
detect uneven or abnormal tire wear, there
may be a need for a wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades* ÐCheck for
cracks or wear if they do not wipe properly.
Doors and engine hood ÐCheck that all
doors and the hood operate properly. Also
ensure all latches lock securely. Lubricate
hinges, latches, rollers and links if neces-
sary. Make sure the secondary latch keeps
the hood from opening when the primary
latch is released.When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights* ÐMake sure the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
INTERIOR MAINTENANCE
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself'' section of this manual.
Warning lights and chimes ÐMake sure
all warning lights and buzzers/chimes are
operating properly.
Windshield wiper and washer* ÐCheck
that the wipers and washer operate properly
and that the wipers do not streak.
Windshield defroster ÐCheck that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.Steering wheel ÐCheck for changes in
the steering conditions, such as excessive
freeplay, hard steering or strange noises.
Seats ÐCheck seat position controls such
as seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints move up and
down smoothly and the locks (if so
equipped) hold securely in all latched posi-
tions.
Seat belts ÐCheck that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Accelerator pedal ÐCheck the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.
Clutch pedal* ÐMake sure the pedal
operates smoothly and check that it has the
proper free travel.
Brakes ÐCheck that the brakes do not pull
the vehicle to one side when applied.

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.
