1997 NISSAN ALTIMA light

WARNING
cNever leave the engine running while
the vehicle is unattended.
cNever leave children unattended in
the vehicle.The power assisted steering is designed to
use a hydraulic pump, driven by the engine,
to assist steering.
If the engine stops or drive belt breaks, you
will still have control of the vehicle. How-
ever, much greater steering effort is
needed, especially in sharp turns or at low
speeds.The brake system has two separate
hydraulic circuits. If one circuit develops a
problem, you will still have braking at two
wheels.
Vacuum assisted brake
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal will be required to stop the
vehicle and the stopping distance will be
longer.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As a
result, your braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
Using the brakes
Avoid resting your foot on the brake pedal

while driving. This overheats the brakes,
increases wear on the brake linings and
pads, and reduces gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.The anti-lock brake system installed in
some models controls the brakes at each
wheel so the wheels do not lock when
braking abruptly or when braking on slip-
pery surfaces. The system detects the rota-
tion speed at each wheel and varies the
brake fluid pressure to prevent each wheel
from locking and sliding. By preventing
wheel lockup, the system helps the driver
maintain steering control and helps to mini-
mize swerving and spinning on slippery
surfaces.
Using the System
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Normal operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h) to completely stop the vehicle. (The
speeds vary according to road conditions.)
When the anti-lock system senses that one
or more wheels are close to locking up, theactuator (under the hood) rapidly applies
and releases hydraulic pressure (like pump-
ing the brakes very quickly). While the ac-
tuator is working, you may feel a pulsation in
the brake pedal and hear a noise or vibra-
tion from the actuator under the hood. This
is normal and indicates that the anti-lock
system is working properly. However, the
pulsation may indicate that road conditions
are hazardous and extra care is required
while driving.
Self-test feature
The anti-lock brake system is sophisticated,
with electronic sensors, electric pumps, and
hydraulic solenoids controlled by a com-
puter. The computer has a built-in diagnos-
tic feature that tests the system each time
you start the engine and move the vehicle at
a low speed in forward or reverse. When the
self-test occurs, you may hear a ``clunk''
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indica-
tion of any malfunction. If the computer
senses any malfunction, it switches the anti-
lock brake system OFF and turns on the
ABS brake warning light in the dashboard.
The brake system then operates normally,
but without anti-lock assistance.

If the light comes on during the self-test or
while you are driving, you should take your
car to your NISSAN dealer for repair at your
earliest convenience.
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 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 4 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 Owner's Manual
index.
Refer to ``Wheels and Tires'' in the
``Do-it-yourself operations'' 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 operations'' 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
operations'' 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
radiator and on the engine block. Refill

Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.
1. If the booster battery is in another ve-
hicle, position the two vehicles to bring
their batteries into close proximity to
each other.
Do not allow the two vehicles to
touch.
2. Apply the parking brake. Move the shift
lever to Neutral (on automatic transmis-
sion models, move the lever to P). Switchoff all unnecessary electrical systems
(lights, heater, air conditioner, etc.).
3. Remove vent caps on the battery (if so
equipped). Cover the battery with an old
cloth to reduce explosion hazard.
4. Connect jumper cables in the sequence
as illustrated.
CAUTION
cAlways connect positive (+) to posi-
tive (+) and negative (þ) to body
ground (for example, strut mounting
bolt, etc. Ð not to the battery).
cMake sure that cables do not touch
moving parts in the engine compart-
ment and that clamps do not contact
any other metal.
5. Start the engine of the booster vehicle
and let it run for a few minutes.
6. Keep the engine speed of the booster
vehicle at about 2,000 rpm, and start
your engine in the normal manner.
CAUTION
Do not keep starter motor engaged for
more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before
trying again.
7. After starting your engine, carefully dis-
connect the negative cable and then the
positive cable.
8. Replace the vent caps (if so equipped).
Be sure to dispose of the cloth used to
cover the vent holes as it may be con-
taminated with corrosive acid.

In order to maintain the appearance of your
vehicle, it is important to take proper care of
it.
In the following cases, please wash your
vehicle as soon as possible to protect the
paint surface:
cAfter a rainfall to prevent possible dam-
age from acid rain
cAfter driving on coastal roads
cWhen contaminants such as soot, bird
droppings, tree sap, metal particles or
bugs get on the paint surfacec
When dust or mud builds up on the surface
Whenever possible, store or park your ve-
hicle inside a garage or in a covered area.
When it is necessary to park outside, park in
a shady area or protect the vehicle with a
body cover.
Be careful not to scratch the paint sur-
face
when putting on or removing the
body cover.
Washing
Wash dirt off with a wet sponge and plenty of
water. Clean the vehicle thoroughly using a
mild soap, a special vehicle soap or general
purpose dish-washing liquid mixed with
clean, lukewarm (never hot) water.
CAUTION
cDo not use strong household soap,
strong chemical detergents, gaso-
line or solvents.
cDo not wash the vehicle in direct
sunlight or while the vehicle body is
hot, as the surface may become
water-spotted.cAvoid using tight-napped or rough
cloths, such as washing mitts. Care
must be taken when removing
caked-on dirt or other foreign sub-
stances so that the paint surface is
not scratched or damaged.
Rinse the vehicle thoroughly with plenty of
clean water.
Inside flanges, seams and folds on the
doors, hatches and hood are particularly
vulnerable to the effects of road salt. There-
fore, these areas must be regularly cleaned.
Take care that the drain holes in the lower
edge of the door are open. Spray water
under the body and in the wheel wells to
loosen the dirt and wash away road salt.
A damp chamois can be used to dry the
vehicle to avoid water spots.
Waxing
Regular waxing protects the paint surface
and helps retain new vehicle appearance.
After waxing, polishing is recommended to
remove built-up residue and to avoid a
``weathered'' appearance.

choosing the proper product.
cWax your vehicle only after a thorough
washing. Follow the instructions supplied
with the wax.
cDo not use a wax containing any abra-
sives, cutting compounds or cleaners
that may damage the vehicle finish.
cIf the surface does not polish easily, use
a ªroad tarº remover and wax again.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint finish
may dull the finish or leave swirl marks.
Only use black wax or black shoe polish on
black urethane or polypropylene bumpers.
Removing spots
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the surface of the paint to avoid lasting
damage or staining. Special cleaning prod-
ucts are available at your NISSAN dealer or
any automotive accessory store.
Underbody
In areas where road salt is used in winter,
the underbody must be cleaned regularly.
This will prevent dirt and salt from buildingup and causing underbody and suspension
corrosion. Before winter and again in the
spring, the underseal must be checked and,
if necessary, retreated.
Cleaning glass
When cleaning the rear window, it may be
easier to clean if the high-mounted stop light
is removed first.
Be careful when removing the high-
mounted stop light to reduce the risk of
damaging the high-mounted stop light
wires.
The high-mounted stop light must be prop-
erly reinstalled before driving your vehicle.
Use glass cleaner to remove smoke and
dust film from the glass surfaces. It is nor-
mal for glass to become coated with a film

CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3. Loosen the oil filter with an oil filter
wrench. Remove the oil filter by turning it
by hand.
CAUTION
Be careful not to burn yourself, as the
engine oil may be hot.
4. Wipe the engine oil filter mounting sur-
face with a clean rag.
Be sure to remove any old rubber gasket
remaining on the mounting surface of the
engine.
5. Coat the rubber gasket on the new filter
with clean engine oil.
6. Screw in the oil filter until a slight resis-
tance is felt, and then tighten an addi-
tional 2/3 turn.
7. Start the engine and check for leakage
around the oil filter. Correct as required.
8. Turn the engine off and wait several
minutes. Check the oil level. Add engine
oil if necessary.
