2018 NISSAN LEAF air condition

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.

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*: 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 fluid level*:
Make sure that the brake
fluid level is 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.
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

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.

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 system
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 a fuel containing more than 15% ethanol in your vehicle. Your
vehicle is not designed to run on a fuel
containing more than 15% ethanol.
Using a fuel containing more than 15%
ethanol in a vehicle not specifically
designed for a fuel containing more
than 15% ethanol can adversely affect
the emission control devices and sys-
tems of the vehicle. Damage caused
by such fuel is not covered by the
NISSAN New Vehicle Limited Warranty. ∙ Do not use fuel that contains the oc-
tane booster methylcyclopentadienyl
manganese tricarbonyl (MMT). Using
fuel containing MMT may adversely
affect vehicle performance and ve-
hicle emissions. Not all fuel dispens-
ers are labeled to indicate MMT con-
tent, so you may have to consult your
gasoline retailer for more details.
Note that Federal and California laws
prohibit the use of MMT in reformu-
lated gasoline.
∙ U.S. government regulations require ethanol dispensing pumps to be iden-
tified by a small, square, orange and
black label with the common abbre-
viation or the appropriate percentage
for that region.
Technical and consumer information10-3

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 cold outside 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
will cause severe damage to the air con-
ditioning system and will require the re-
placement 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.
