2018 NISSAN VERSA SEDAN ECU

REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-
tipped
Aspark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the "Maintenance and sched-
ules" section of this manual. Do not service
platinum-tipped spark plugs by cleaning or
regapping.
∙ Always replace spark plugs with rec-
ommended or equivalent ones.
WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect
socket can damage the spark plugs.
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.
WARNING
∙ Operating the engine with the air cleaner filter off can cause you or oth-
ers to be burned. The air cleaner filter
not only cleans the intake air, it also
stops the flame if the engine back-
fires. If the air cleaner is not installed
and the engine backfires, you could be
burned. Never drive with the air
cleaner filter off. Be cautious working
on the engine when the air cleaner is
off.

Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.For additional information re-
garding brake inspections, refer to the ap-
propriate maintenance schedule informa-
tion in the "Maintenance and schedules"
section of this manual.
If any electrical equipment does not oper-
ate, check for an open fuse.
Fuses are used in the passenger compart-
ment. Spare fuses are provided and can be
found in the passenger compartment fuse
box.
When installing a fuse make sure the fuse is
installed in the fuse box securely.
ENGINE COMPARTMENT
WARNING
Never use a fuse of a higher or lower
amperage rating than that specified on
the fuse box cover. This could damage
the electrical system or electronic con-
trol units or cause a fire.
Fusible links

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces 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.
TIRE CHAINS
Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When installing
tire chains, make sure they are the proper
size for the tires on your vehicle and are
installed according to the chain manufac-
turer’s suggestions.
Use only SAE class “S”
chains. Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a
winter traction device (tire chains or
cables). The minimum clearances are de-
termined using the factory equipped tires.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chain must be secured or removed to prevent
the possibility 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.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.
Do-it-yourself8-35

Some day-to-day and regular mainte-
nance is essential to maintain your vehicle
good mechanical condition, as well as its
emissions and engine performance.
It is the owner’s responsibility to make sure
that the scheduled maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. 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. They are essential
for proper vehicle operation. It is your re-
sponsibility to perform these procedures
regularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and only
a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this sec-
tion are required to be serviced at regular
intervals. However under severe driving
conditions, additional or more frequent
maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced. It is recom-
mended that you visit a NISSAN dealer for
this service.
NISSAN technicians are well-trained spe-
cialists and are kept up-to-date with the
latest service information through techni-
cal bulletins, service tips and training pro-
grams. They are completely qualified to
work on NISSAN vehiclesbeforework be-
gins.
You can be confident that a NISSAN deal-
er’s service department can perform the
service needed to meet the maintenance
requirements on your vehicle. During the normal day-to-day operation of
the vehicle, general maintenance should
be performed regularly as prescribed in
this section. If you detect any unusual
sounds, vibrations or smells, be sure to
check for the cause or have it checked
promptly. In addition, it is recommended
that you visit a NISSAN dealer if you think
that repairs are required.
When performing any checks or mainte-
nance work, closely observe the “Mainte-
nance precautions” in the “Do-it-yourself ”
section of this manual.

secondary latch keeps the hood from
opening when the primary latch is re-
leased.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires should be rotated ev-
ery 5,000 miles (8,000 km).
Tires*: Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the
TPMS transmitter grommet seal, valve core
and cap when the tires are replaced due to
wear or age. Wheel alignment and balance:
If the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may
be a need for wheel alignment. If the steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield: Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc. Accelerator pedal:
Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Continuously Variable Transmission

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*: Check the fluid level in each cell.
The fluid should be at the bottom of the
filler opening. Vehicles operated in high
temperatures or under severe conditions
require frequent checks of the battery fluid
level.
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
running (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 belts*: Make sure the drive
belts are 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.
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.
9-4Maintenance and schedules

5.Determine the combined weight
of luggage and cargo being
loaded on the vehicle. That
weight may not safely exceed the
available cargo and luggage load
capacity calculated in step 4.
Before driving a loaded vehicle, con-
firm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. For addi-
tional information, refer to “Measure-
ment of weights” in this section.
Also check tires for proper inflation
pressures. For additional informa-
tion, refer to “Tire and Loading Infor-
mation label” in this section.
LOADING TIPS
∙ The GVW must not exceed GVWR or GAWR as specified on the F.M-
.V.S.S. certification label.
∙ Do not load the front and rear axle to the GAWR. Doing so will
exceed the GVWR.
WARNING
∙ Properly secure all cargo with ropes or straps to help prevent
it from sliding or shif ting. Do not
place cargo higher than the
seatbacks. In a sudden stop or
collision, unsecured cargo could
cause personal injury.
∙ Do not load your vehicle any heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts of your
vehicle can break, tire damage
could occur, or it can change the
way your vehicle handles. This
could result in loss of control
and cause personal injury.
∙
Overloading and improper load-
ing not only can shorten the life
of your vehicle and the tire, but
can also cause unsafe vehicle
handling and longer braking dis-
tances. This may cause a prema-
ture tire failure which could re-
sult in a serious accident and
personal injury. Failures caused
by overloading are not covered
by the vehicle’s warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shif ts that could affect the
balance of your vehicle. When the ve-
hicle is loaded, drive to a scale and
weigh the front and the rear wheels
separately to determine axle loads.
Individual axle loads should not ex-
ceed either of the Gross Axle Weight
Ratings (GAWR). The total of the axle
loads should not exceed the Gross
Vehicle Weight Rating (GVWR). These
ratings are given on the vehicle cer-
tification label. If weight ratings are
exceeded, move or remove items to
bring all weights below the ratings.
