service NISSAN SENTRA 2020 Owner´s Manual

Parking brake:Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*:
Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: This vehicle is equipped with a
sealed maintenance free battery. It is rec-
ommended that you visit a NISSAN dealer
for service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not run-
ning (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances. In these cases, the battery may need to
be charged to maintain battery health.
Brake and clutch (if so equipped) fluid
level*:
Make sure that the brake and clutch
fluid levels are between the MIN and MAX
lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belt*: Make sure the drive belt
is not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level surface with
the engine off. Wait more than 15 minutes
for the oil to drain back into the oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, refer to “Exhaust gas (carbon mon-
oxide)” in the “Starting and driving” section
of this manual.
9-4Maintenance and schedules

Fluid leaks:Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
fuel fumes are evident, check for the cause
and have it corrected immediately.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise
rust may form on the floor pan, frame, fuel
lines and exhaust system. At the end of
winter, the underbody should be thor-
oughly flushed with plain water, in those
areas where mud and dirt may have accu-
mulated. For additional information, refer
to the “Appearance and care” section of this
manual.
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, refer to
“General maintenance” in this section.
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual.NOTE:
NISSAN does not advocate the use of
non-OEM approved af termarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the af termar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to “Recom-
mended fluids/lubricants and capaci-
ties” in the “Technical and consumer in-
formation” section of this manual.
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive belt*: Check engine drive belt for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belt.
Engine air filter: Replace at specified inter-
vals. When driving for prolonged periods in
dusty conditions, check/replace the filter
more frequently.
EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS

quired. (in-tank type filter) Fuel lines*:
Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place parts as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the type as originally
equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing,
cracks, deterioration, and signs of leaking.
Replace any deteriorated or damaged
parts immediately.
Brake pads, rotors, drums and linings:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or dam-
aged parts immediately.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary.
In-cabin microfilter: Replace at specified
intervals. When driving for prolonged peri-
ods in dusty conditions, replace the filter
more frequently. Steering gear and linkage, axle and sus-
pension parts, drive shaf t boots:
Check
for damage, looseness, and leakage of oil
or grease. Under severe driving conditions,
inspect more frequently.
Tire rotation: Tires should be rotated every
7,500 miles (12,000 km) according to the in-
structions under “General maintenance” in
this section. When rotating tires, check for
damage and uneven wear. Replace if nec-
essary.
Transmission fluid/oil: Visually inspect for
signs of leakage at specified intervals. If
using a car-top carrier, or driving on rough
or muddy roads:
• Replace the manual transaxle gear oil ev- ery 20,000 miles or 24 months.
• Replace the CVT fluid every 60,000 miles (96,000 km) or request the dealer to in-
spect the fluid deterioration data using a
CONSULT. If the deterioration data is
more than 210000, replace the CVT fluid.
9-6Maintenance and schedules

To help ensure smooth, safe and economi-
cal driving, NISSAN provides two mainte-
nance schedules that may be used, de-
pending upon the conditions in which you
usually drive. These schedules contain
both distance and time intervals, up to
120,000 miles (192,000 km)/96 months. For
most people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals
shown in the schedule.
Af ter 120,000 miles (192,000 km)/96
months, continue maintenance at the
same mileage/time intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditionsshould be per-
formed on vehicles that are driven under
especially demanding conditions. Addi-
tional maintenance items should be per-
formed if you primarily operate your vehicle
under the following conditions:
• Repeated short trips of less than 5 miles (8 km). • Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi or
door-to-door delivery use.
• Driving in dusty conditions.
• Driving on rough, muddy or salt spread roads.
• Using a car-top carrier. The following tables show the standard
maintenance schedule. Depending upon
weather and atmospheric conditions,
varying road surfaces, individual driving
habits and vehicle usage, additional or
more frequent maintenance may be re-
quired.
Af ter 120,000 miles (192,000
km)/96 months, continue maintenance
at the same mileage/time interval.

FUEL RECOMMENDATION
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
CAUTION
• Only vehicles with the E-85 filler door
label can operate on E-85. Fuel sys-
tem or other damage can occur if
E-85 is used in vehicles that are not
designed to run on E-85.
• Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
the warranty coverage.
• Under no circumstances should a
leaded gasoline be used, because
this will damage the three-way
catalyst. •
Do not use E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed
to run on E-15 or E-85 fuel. Using E-15
or E-85 fuel in a vehicle not specifi-
cally designed for E-15 or E-85 fuel
can adversely affect the emission
control devices and systems of the
vehicle. Damage caused by such fuel
is not covered by the NISSAN New Ve-
hicle Limited Warranty.
• Do not use fuel that contains the oc-
tane booster methylcyclopentadi-
enyl manganese tricarbonyl (MMT).
Using fuel containing MMT may ad-
versely affect vehicle performance
and vehicle emissions. Not all fuel
dispensers are labeled to indicate
MMT content, so you may have to
consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of
MMT in reformulated gasoline.
• U.S. government regulations require
ethanol dispensing pumps to be
identified by a small, square, orange
and black label with the common ab-
breviation or the appropriate per-
centage for that region.
Gasoline specifications
NISSAN recommends using gasoline that
meets the World-Wide Fuel Charter (WWFC)
specifications where it is available. Many of
the automobile manufacturers developed
this specification to improve emission con-
trol system and vehicle performance. Ask
your service station manager if the gaso-
line meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing re-
formulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. NISSAN supports efforts towards
cleaner air and suggests that you use re-
formulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, Methyl
Tert-butyl Ether (MTBE) and methanol with
or without advertising their presence.
NISSAN does not recommend the use of
fuels of which the oxygenate content and
the fuel compatibility for your NISSAN can-
not be readily determined. If in doubt, ask
your service station manager.
10-4Technical and consumer information

Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Using en-
gine oil and filters that are not of the speci-
fied quality, or exceeding recommended oil
and filter change intervals could reduce
engine life. Damage to the engine caused
by improper maintenance or use of incor-
rect oil and filter quality and/or viscosity is
not covered by the NISSAN New Vehicle
Limited Warranty.
Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
Operation under the following conditions may
require more frequent oil and filter changes:
• repeated short distance driving at coldoutside temperatures
• driving in dusty conditions
• extensive idling
• stop and go commuting
For additional information, refer to the
“Maintenance and schedules” section of
this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFO-1234yf (R-1234yf ) and
NISSAN A/C system oil Type PAG or the
exact equivalents.
CAUTION
The use of any other refrigerant or oil
may cause severe damage to the air
conditioning system and will require
the replacement of all air conditioner
system components.
The refrigerant HFO-1234yf (R-1234yf ) in
your NISSAN vehicle does not harm the
earth's ozone layer. Although this refriger-
ant does not affect the earth's atmo-
sphere, certain government regulations re-
quire the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. A NISSAN dealer has
the trained technicians and equipment
needed to recover and recycle your air con-
ditioner system refrigerant. It is recommended that you visit a NISSAN
dealer when servicing your air conditioner
system.
10-8Technical and consumer information

Manual Transmission (if so
equipped)
• Always tow with the manual transmis-sion in N (Neutral).
• Af ter towing 500 miles (805 km), start and idle the engine with the transmission in N
(Neutral) for two minutes. Failure to idle
the engine af ter every 500 miles (805 km)
of towing may cause damage to internal
transmission parts.
Continuously Variable
Transmission (if so equipped)
To tow a vehicle equipped with a continu-
ously variable transmission, an appropriate
vehicle dolly MUSTbe placed under the
towed vehicle's drive wheels. Alwaysfollow
the dolly manufacturer's recommenda-
tions when using their product. DOT (Department of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature
A
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades repre-
sent the tire's ability to stop on wet pave-ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
WARNING
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include ac-
celeration, cornering, hydroplaning, or
peak traction characteristics.
Temperature A, B and C
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat, and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Mo-
tor Safety Standard No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the mini-
mum required by law.
UNIFORM TIRE QUALITY GRADING
Technical and consumer information10-19

This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a ve-
hicle's systems performed. The EDR is de-
signed to record data related to vehicle dy-
namics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to re-
cord such data as:
• How various systems in your vehicle wereoperating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
• How fast the vehicle was traveling.
• Sounds are not recorded.
These data can help provide a better un-
derstanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-
trivial crash situation occurs; no data are
recorded by the EDR under normal driving
conditions and no personal data (e.g.
name, gender, age and crash location) are
recorded. However, other parties, such as law enforcement, could combine the EDR
data with the type of personally identif ying
data routinely acquired during a crash in-
vestigation.
To read data recorded by an EDR, special
equipment is required and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer and NISSAN
dealer, other parties, such as law enforce-
ment, that have the special equipment, can
read the information if they have access to
the vehicle or the EDR. EDR data will only be
accessed with the consent of the vehicle
owner or lessee or as otherwise required or
permitted by law.
