1999 NISSAN SENTRA Owners Manual

Floor mat positioning aid
(driver's side only)
All models include a front floor mat bracket
to act as a floor mat positioning aid. NIS-
SAN floor mats have been specially de-
signed for your vehicle model. The driver's
side floor mat has a grommet hole incorpo-
rated in it. Position the mat by placing the
floor mat bracket hook through the floor mat
grommet hole while centering the mat in the
footwell.
Periodically check to make certain the mats
are properly positioned.
Floor mats
The use of genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior.No
matter what mats are used, be sure they
are fitted for your vehicle and are prop-
erly positioned in the footwell to prevent
interference with pedal operation.Mats
should be maintained with regular cleaning
and replaced if they become excessively
worn.
Seat belts
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely before using them.
WARNING
Do not allow wet belts to roll up in the
retractor. NEVER use bleach, dye, or
chemical solvents since these may se-
verely weaken the seat belt webbing.

Most common factors contributing
to vehicle corrosion.
1. The accumulation of moisture-retaining
dirt and debris in body panel sections,
cavities, and other areas.
2. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor traffic accidents.
Environmental factors influence the
rate of corrosion.
Moisture
Accumulation of sand, dirt and water on the
vehicle body underside can accelerate cor-
rosion. Wet floor coverings will not dry com-
pletely inside the vehicle, and should be
removed for drying to avoid floor panel
corrosion.
Relative humidity
Corrosion will be accelerated:
cin areas of high relative humidity.
cin areas where the temperatures stay
above freezing.
cwhere atmospheric pollution exists.cwhere road salt is used.
Temperature
High temperatures accelerate the rate of
corrosion to those parts which are not well
ventilated.
Air pollution
Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use accelerates the corrosion process.
Road salt also accelerates the disintegra-
tion of paint surfaces.To protect your vehicle from
corrosion:
cwash and wax your vehicle often to keep
the vehicle clean.
calways check for minor damage to the
paint and repair it as soon as possible.
ckeep drain holes at the bottom of the
doors open to avoid water accumulation.
ccheck the underbody for accumulation of
sand, dirt or salt. If present, wash with
water as soon as possible.
CAUTION
cNEVER remove dirt, sand or other
debris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner
or broom.
cNever allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle as this
may damage them.

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the gearshift
control lever to N (Neutral). For an
automatic transmission, move the
shift lever to P (Park).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cBe sure to turn the ignition key to the
OFF or LOCK position. When the
ignition key is in the ON or ACC
position, the cooling fan may start to
operate suddenly even when the en-
gine is not running.cIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.
cIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it
is supported by only a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and battery.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, the fuel filter or fuel lines
should be serviced by an authorized
NISSAN dealer because the fuel
lines are under high pressure even
when the engine is off.
CAUTION
cDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
cNever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is ON.
c
Avoid contact with used motor oil.
Improperly disposed motor oil and/or
other vehicle fluids can hurt the en-
vironment. Always conform to local
regulations for disposal of vehicle
fluid.
This ``Do-it-yourself'' section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors;
therefore, additional engine cooling system
additives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only Genuine NISSAN Anti-
freeze Coolant or equivalent with the
proper mixture ratio of 50% coolant and
50% demineralized water or distilled
water. The use of other types of coolant
solutions may damage the engine cool-
ing system.

WARNING
cNever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Serious
burns could be caused by high pres-
sure fluid escaping from the radia-
tor.
cSee precautions in ``If your vehicle
overheats'' found in the ``In case of
emergency'' section of this manual.
c
The radiator is equipped with a pres-
sure cap. Use only a genuine NISSAN
cap when replacement is required.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below MIN, add coolant up to the MAX
level. If the reservoir tank is empty, check
the coolant level in the radiatorwhen the
engine is cold.If there is insufficient cool-
ant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir tank up to the MAX level.
