service interval NISSAN SENTRA 1997 B14 / 4.G Owners Manual

Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
the specified periodic maintenance, as well
as general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance care. You are a
vital link in the maintenance chain.
General maintenance
General maintenance includes those items
which should be checked during normal
day-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these procedures regularly as
prescribed.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, your NISSAN dealer.
Periodic maintenance
The maintenance items listed in this part are
required to be serviced at regular intervals.
However, under severe driving conditions,
additional or more frequent maintenance is
required.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists and are kept up to date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN's vehiclesbe-
forethey work on your vehicle, rather than
after they have worked on it.
You can be confident that your NISSAN
dealer's service department performs the
best job to meet the maintenance require-
ments on your vehicle Ð in a reliable and
economical way.
During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations
or smells, be sure to check for the cause or
have your NISSAN dealer do it promptly. In
addition, you should notify your NISSAN
dealer if you think repairs are required.
When performing any checks or maintenance
work, closely observe the precautions in the
``Do-it-yourself operations'' section.
OUTSIDE THE VEHICLE
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Tires* ÐCheck the pressure with a gauge
periodically when at a service station, in-
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 nuts are missing, and check
for any loose nuts. Tighten if necessary.
GENERAL MAINTENANCE

To ensure smooth, trouble-free, safe and
economical driving, NISSAN provides two
different maintenance schedules that may
be used, depending upon the conditions in
which you usually drive. These schedules
contain both distance and time intervals, up
to 60,000 miles (96,000 km)/48 months. For
most people, the odometer reading indi-
cates when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals shown
in the schedule.After 60,000 miles (96,000
km) or 48 months, continue periodic
maintenance at the same mileage/time
intervals.
SCHEDULE 1
Follow Periodic Maintenance Schedule 1 if
your driving habits frequently include one or
more of the following driving conditions:
cRepeated short trips of less than 5
miles (8 km).
cRepeated short trips of less than 10
miles (16 km) with outside tempera-
tures remaining below freezing.
cOperating in hot weather in stop-
and-go ``rush hour'' traffic.cExtensive idling and/or low speed
driving for long distances, such as
police, taxi or door-to-door delivery
use.
cDriving in dusty conditions.
cDriving on rough, muddy, or salt
spread roads.
cTowing a trailer, using a camper or a
car-top carrier.
SCHEDULE 2
Follow Periodic Maintenance Schedule 2 if
none of the driving conditions shown in
Schedule 1 apply to your driving habits.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct quality
and viscosity oil to ensure satisfactory en-
gine life and performance. Nissan recom-
mends the use of a low friction oil (energy
conserving oil) in order to improve fuel
economy and conserve energy. Oils which
do not have the specified quality label
should not be used as they could cause
engine damage.
Only those engine oils with the AmericanPetroleum Institute (API) CERTIFICATION
MARK on the front of the container should
be used. This type of oil supersedes the
existing API SG or SH and Energy Conserv-
ing II categories.
If you cannot find engine oil with the CER-
TIFICATION MARK, an API SG or SH and
Energy Conserving II oil with API Service
Symbol may be used. An oil with a single
designation SG or SH, or in combination
with other categories (for example, SG/CC
or SG/CD) may also be used if one with the
API CERTIFICATION MARK cannot be
found.Mineral based or synthetic type oils may be
used in your NISSAN vehicle. However,
these oils must meet the API quality and
SAE viscosity ratings specified for your ve-
hicle. Do not mix mineral based and syn-
thetic type oils in the engine at the same
time.
Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness
changes with temperature. Because of this,
it is important to select the engine oil viscos-
ity based on the temperatures at which the
vehicle will be operated before the next oil
change. The chart ``Recommended SAE
viscosity number'' shows the recommended
oil viscosities for the expected ambient tem-
peratures. Choosing an oil viscosity other
than that recommended could cause seri-
ous engine damage.

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, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
cIf the engine temperature coolant rises
to an extremely high temperature when
the air conditioning system is on, turn off
the air conditioner. Coolant heat can be
additionally vented by opening the win-
dows, 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 your vehicle's
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 compen-
sate for this, make a larger than normal
turning radius during the turn.cCrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change the oil in
the transmission more frequently.
See the Maintenance Schedule.DOT Quality Grades: All passenger car tires
must conform to Federal Safety Require-
ments in addition to these grades.
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However,
relative tire performance depends on actual
driving conditions, and may vary signifi-
cantly from the norm due to variations in
driving habits, service practices and differ-
ences in road characteristics and climate.
Traction A, B and C
Traction grades are A (the highest), B and C.
They represent a tire's ability to stop on wet
pavement as measured under controlled con-
ditions, on specified government test sur-
faces of asphalt and concrete. A tire marked
with a C may have poor traction performance.
WARNING
The traction grade assigned to your
vehicle tires is based on straight line
