Brake NISSAN SENTRA 2023 Manual Online

Two-Wheel Drive models with
manual transmission
NISSAN recommends that towing dollies
be used when towing your vehicle or place
the vehicle on the flatbed truck as
illustrated.
If you must use a pull behind tow truck put
the manual transmission in N (Neutral).
Your vehicle speed should never exceed 60
mph (97 km/h) when towing your vehicle.
Af ter towing 500 miles, start and idle the
engine with the transmission in N (Neutral)
for two minutes. Failure to idle the engineaf ter every 500 miles of towing may cause
damage to the transmission’s internal
parts.
CAUTION
Failure to follow these guidelines can
result in severe transmission damage.
• If you have to tow manual transmis-
sion models with the rear wheels on
the ground (if you do not use towing
dollies) or four wheels on the ground:
– Always release the parking brake.
– Move the transmission shif t lever
to the N (Neutral) position –
Observe the following restricted
towing speeds and distances for
manual transmission models
only:
Speed: Below 60 mph (97 km/h)
Distance: Less than 500 miles (805
km)
When towing long distances or speeds in
excess of 60 mph (97 km/h), remove the
propeller shaf t before towing to prevent
damage to the transmission. For additional
information, it is recommended that you
visit a NISSAN dealer.
VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
To avoid vehicle damage, serious per-
sonal injury or death when recovering a
stuck vehicle:
• Contact a professional towing ser-
vice to recover the vehicle if you have
any questions regarding the recov-
ery procedure.
• Tow chains or cables must be at-
tached only to main structural mem-
bers of the vehicle.

When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, theshif t lever in P (Park) position (Continu-
ously Variable Transmission models) or
the shif t lever in the N (Neutral) position
(manual transmission models) and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t le-
ver in the P (Park) position (Continuously
Variable Transmission models) or the
shif t lever in the N (Neutral) position
(manual transmission models) and with
the parking brake applied, fully apply and
release all pedals. The floor mat must
not interfere with pedal operation or
prevent the pedal from returning to its
normal position. It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle.
The illustration shows the location of the
floor mat positioning hooks.
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 in the shade before using them. For
additional information, see “Seat belt main-
tenance” (P. 1-20).

CAUTION
• NEVER remove dirt, sand or other de-
bris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner
or broom.
• Never allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle as this
may damage them.
Chemicals used for road surface de-icing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be
cleaned periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended that you visit a
NISSAN dealer.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
• Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shif t lever
to N (Neutral). For CVT models, move
the shif t lever to P (Park).
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
• It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle. •
If you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
• Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• Because the fuel lines on gasoline
engine models are under high pres-
sure even when the engine is off, it is
recommended that you visit a
NISSAN dealer for service of the fuel
filter or fuel lines.
• Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without
warning, even if the ignition switch is
in the OFF position and the engine is
not running. To avoid injury, always
disconnect the negative battery
cable before working near the fan.
CAUTION
• Do not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down. •
Avoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
• Never leave the engine or the trans-
mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, see
“Owner's Manual/Service Manual order in-
formation” (P. 10-25).
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check
the oil level. It should be between the H
(High) and L (Low) marksOB. This is the
normal operating oil level range. If the oil
level is below the L (Low) mark
OA,re-
move the oil filler cap and pour recom-
mended oil through the opening. Do not
overfill
OC.
6. Recheck oil level with the dipstick.
CAUTION
• Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the
engine, and such damage is not cov-
ered by warranty.
• It is normal to add some oil between
oil maintenance intervals or during
the break-in period, depending on
the severity of operating conditions.
Make sure to follow the engine oil changing
intervals in the maintenance booklet. Op-
erating under the following conditions may
require more frequent oil change:
• repeated short distance driving
• driving in dusty conditions
• stop and go commuting.

voir. If there is no fluid in the tube, add fluid. Add a washer solvent to the washer for
better cleaning. In the winter season, add a
windshield washer antifreeze. Follow the
manufacturer's instructions for the mix-
ture ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of windshield-washer fluid.
Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner &
Antifreeze or equivalent.
CAUTION
• Do not substitute engine antifreeze
coolant for windshield-washer fluid.
This may result in damage to the
paint.
• Do not fill the windshield-washer
fluid reservoir with washer fluid con-
centrates at full strength. Some
methyl alcohol based washer fluid
concentrates may permanently stain
the grille if spilled while filling the
windshield-washer fluid reservoir.
