Engine NISSAN SENTRA 1997 B14 / 4.G Owner's Guide

cKeep your engine tuned up.
cFollow the recommended periodic main-
tenance schedule.
cKeep the tires inflated to the correct
pressure. Low pressure increases tire
wear and wastes fuel.
cKeep the front wheels in correct align-
ment. Improper alignment increases tire
wear and lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only
when necessary.
cWhen cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.
WARNING
Do not park the vehicle over flammable
materials such as dry grass, waste pa-
per or rags. They may ignite and cause
a fire.
1. Firmly apply the parking brake.
2.Manual transmission models:
Place the gearshift lever in the R (Re-
verse) position. When parking on an up-
hill grade, place the gearshift lever in 1
(First) gear.Automatic transmission models:
Move the gearshift lever to the P (Park)
position.
WARNING
Safe parking procedures require that
both the parking brake be set and the
transmission placed into the P (Park)
position (automatic transmission) or in
the appropriate gear (manual transmis-
sion). Failure to do so could cause the
vehicle to move unexpectedly or roll
away and result in an accident. Make

sure the shift lever has been pushed as
far forward as it can go and cannot be
moved without depressing the button
at the end of the lever.
3. To help prevent the vehicle from rolling
into traffic when parked on an incline, it is
a good practice to turn the wheels as
illustrated.
cHEADED DOWNHILL WITH CURB:
s1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
cHEADED UPHILL WITH CURB:
s2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
cHEADED UPHILL OR DOWNHILL, NO
CURB:
s3
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Turn the ignition key to the LOCK posi-
tion and remove the key.
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 the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns or at low
speeds.
POWER STEERING SYSTEM
4-16
ZX

The brake system has two separate hy-
draulic circuits. If one circuit develops a
problem, you will still have braking at
two wheels.
Vacuum assisted brakes
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 pedalwhile 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 controls the
brakes at each wheel so the wheels do not
lock when braking abruptly or when braking
on slippery surfaces. The system detects
the rotation speed at each wheel and varies
the brake fluid pressure to prevent each
wheel from locking and sliding. By prevent-
ing wheel lockup, the system helps the
driver maintain steering control and helps to
minimize 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, the
actuator (under the hood) rapidly applies
BRAKE SYSTEM ANTI-LOCK BRAKE SYSTEM
(ABS) (if so equipped)
4-17
ZX

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 check orwhile driving, take your vehicle to your NIS-
SAN dealer for repair at your earliest con-
venience.
WARNING
cThe anti-lock brake system is a so-
phisticated device, but it cannot pre-
vent accidents resulting from care-
less or dangerous driving tech-
niques. It can help maintain vehicle
control during braking on slippery
surfaces, but remember that the
stopping distance on slippery sur-
faces 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 distance from the vehicle in
front of you. Ultimately, the respon-
sibility for safety of self and others
rests in the hands of the driver.
cTire type and condition may also
affect braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all 4 wheels.c
When 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
``Tire placard'' in the Owner's Manual
index.
cRefer 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 to it through the key hole.
If the lock becomes frozen, heat the key
before 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. Refillbefore operating the vehicle. See ``Chang-
ing Engine Coolant'' in the ``Do-it-yourself
operations'' section.
Tire equipment
1. SUMMER tires are of a tread design to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all
four wheels. Please consult your NIS-
SAN dealer for the tire type, size, speed
rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
provinces and states prohibit their use.
Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used if desired. Make
sure they are of proper size for the tires
on your vehicle and are installed accord-ing to the chain manufacturer's sugges-
tions.
Use of tire chains may be prohibited
according to location. Check the local
laws before installing tire chains. When
installing tire chains, make sure they are
of proper size for the tires on your vehicle
and are installed according to the chain
manufacturer's suggestions.Use only
SAE Class ªSº chains.Other types may
damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose
end links of the tire chain must be se-
cured or removed to prevent the possi-
bility of whipping action damage to the
fenders or underbody. If possible, avoid
fully loading your vehicle when using tire
chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Never install tire chains on T-type spare
tires. Do not use tire chains on dry roads.
COLD WEATHER DRIVING

Special winter equipment
It is recommended that the following items
be carried in the vehicle during winter:
1. A scraper and stiff-bristled brush to re-
move ice and snow from the windows
and wiper blades.
2. A sturdy, flat board to be placed under
the jack to give it firm support.
3. A shovel to dig the vehicle out of snow-
drifts.
4. Extra window washer fluid to refill the
reservoir tank.
Driving on snow or ice
WARNING
cWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow or ice can be slick
and very hard to drive on. The ve-
hicle will have a lot less traction or
``grip'' under these conditions. Try to
avoid driving on wet ice until the
road is salted or sanded.cWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction.
c
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
cAllow greater following distances on
slippery roads.
cWatch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while
actually on the ice, and avoid any
sudden steering maneuvers.
cDo not use cruise control on slippery
roads.
cSnow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle.
Engine block heater/Engine heater
(if so equipped)
An engine block heater/engine heater to
assist extreme cold temperature starting is
available through your NISSAN dealer.
WARNING
Do not use your heater with an un-
grounded electrical system or two-
pronged (cheater) adapters. You can be
injured by an electrical shock if you use
an ungrounded connection.

If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the
parking brake. Shift the manual transmis-
sion into Reverse (R), or the automatic
transmission into P (Park).
4. Turn off the engine.
5. Raise the hood to warn other traffic, and
to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the ve-
hicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
cMake sure that the parking brake is
securely applied and the manual
transmission is shifted into Reverse
(R), or the automatic transmission
into P (Park).cNever change tires when the vehicle
is on a slope, ice or slippery areas.
This is hazardous.
cNever change tires if oncoming traf-
fic is close to your vehicle. Wait for
professional road assistance.

cNever jack up the vehicle more than
necessary.
cNever use blocks on or under the
jack.
cDo not start or run engine while
vehicle is on the jack as it may cause
the vehicle to move.
cDo not allow passengers to stay in
the vehicle while it is on the jack.
cNever run the engine with a wheel off
the ground. It may cause the vehicle
to move. This is especially true for
models equipped with limited slip
differential carrier.
Installing wheel
The T-type spare tire is designed for
emergency use. See specific instruc-
tions under the heading ``Wheels and
tires'' in the ``Do-it- yourself operations''
section.
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and tighten
the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel
nuts alternately and evenly until they are
tight.4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts se-
curely in the sequence as illustrated.
WARNING
cIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
cDo not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
As soon as possible, tighten the wheel
nuts to the specified torque with a torque
wrench.
Wheel nut tightening torque:
72 to 87 ft-lb (98 to 118 N²m)
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 lubrication interval.
Adjust tire pressure to the COLD
pressure.

center pillar.
cRetighten the wheel nuts when the
vehicle has been run for 600 miles
(1,000 km).
5. Securely store the spare tire and jacking
equipment in the vehicle.
WARNING
cAlways make sure that the spare tire
and jacking equipment are properly
secured after use. Such items can
become dangerous projectiles in an
accident or sudden stop.
cThe T-type spare tire and small size
spare tire are designed for emer-
gency use. See specific instructions
under the heading ``Wheels and
tires'' in the ``Do-it-yourself opera-
tions'' section.To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
cIf done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could
also damage your vehicle.
cExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away
from the battery.
cDo not allow battery fluid to come
into contact with eyes, skin, cloth or
painted surfaces. Battery fluid is a
corrosive sulfuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
cKeep battery out of the reach of
children.
cThe booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.
