2. Take the hose1and the power plug2out
of the air compressor. Remove the cap of the
bottle holder from the air compressor.3. Remove the cap from the tire sealant bottle,
and screw the bottle clockwise onto the bottle
holder. (Leave the bottle seal intact. Screwing
the bottle onto the bottle holder will pierce the
seal of the bottle.)
4. Remove the cap from the tire valve on the flat
tire.5. Remove the protective cap
Aof the hose
and screw the hose securely onto the tire
valve. Make sure that the pressure release
valve
Bis securely tightened. Make sure that
the air compressor switch is in the OFF (O)
position, and then insert the power plug into
the power outlet in the vehicle.
In case of emergency6-7

6. Push the power switch to the “ACC” position.
Then turn the compressor switch to the ON
(−) position and inflate the tire up to the
pressure that is specified on the Tire and
Loading Information label affixed to the driv-
er’s side center pillar if possible, or to the
minimum of 26 psi (180 kPa) . Turn the air
compressor off briefly in order to check the
tire pressure with the pressure gauge.
If the tire is inflated to higher than the specified
pressure, lower the tire pressure by releasing
air with the pressure release valve.
NOTE:
The compressor tire pressure gauge may
show a pressure reading of 87 psi (600
kPa) for about 30 seconds while inflat-
ing the tire. The pressure gauge is indi-
cating the pressure inside the sealant
can. When the sealant has been injected
into the tire the pressure gauge will drop
and indicate actual tire pressure.
WARNING
To avoid serious personal injury while
using the emergency tire puncture repair
kit:
•Securely tighten the compressor hose
to the tire valve. Failure to do so can
cause the sealant to spray into the air
and get into your eyes or on the skin.
•Do not stand directly beside the dam-
aged tire while it is being inflated be-
cause of the risk of the rupture. If there
are any cracks or bumps, turn the com-
pressor off immediately.
If the tire pressure does not increase to26 psi
(180 kPa) within 10 minutes, the tire may
be seriously damaged andthe tire cannotbe repaired with this tire repair kit.Con-
tact a NISSAN certified LEAF dealer.
7. When the tire pressure is at the specified
amount, turn the air compressor off. If the tire
cannot be inflated to the specified amount,
the air compressor can be turned off at the
minimum of 26 psi (180 kPa) . Remove the
power plug from the power outlet and quickly
remove the hose from the tire valve. Attach the
protective cap and valve cap. Properly stow
the emergency tire puncture repair kit in the
cargo area.
CAUTION
To avoid serious personal injury when
stowing the emergency tire puncture re-
pair kit:
•Keep the sealant bottle screwed into
the compressor. Failure to do so can
cause the sealant to spray into the air
and get into your eyes or on the skin.
8. Immediately drive the vehicle for 10 minutes
or 2 miles (3 km) at a speed below 50 MPH
(80 km/h) .
9. After driving, make sure that the air compres-
sor switch is in the OFF position, then screw
the hose securely onto the tire valve. Check
6-8In case of emergency

Your new NISSAN has been designed to have
minimum maintenance requirements with long
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your NIS-
SAN’s fine mechanical condition, as well as its
EV (Electric Vehicle) system 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 the proper
maintenance care. You are a vital link in the main-
tenance chain.
SCHEDULED MAINTENANCE
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide”. You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
GENERAL MAINTENANCE
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-eration. It is your responsibility 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 certified LEAF dealer.
WHERE TO GO FOR SERVICE
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and serviced by a NISSAN certified
LEAF dealer.
NISSAN technicians are well-trained specialists
and are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership information systems. They
are completely qualified to work on NISSAN ve-
hiclesbeforework begins.
You can be confident that a NISSAN certified
LEAF dealer’s service department performs the
best job to meet the maintenance requirements
on your vehicle — in a reliable and economical
way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have a
NISSAN certified LEAF dealer do it promptly. In
addition, you should notify a NISSAN certified
LEAF dealer if you think that repairs are required.

fluid level is between the MAX and MIN lines on
the reservoir.
Coolant level*:Check the coolant level when
the motor compartment is cold.
Fluid leaks:Check under the vehicle for water
or other fluid leaks after the vehicle has been
parked for a short period of time. Water dripping
from the air conditioner after use is normal. If you
notice any leaks, 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 that
the hoses have no cracks, deformation, rot or
loose connections.
Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan and frame. At
the end of winter, the underbody should be thor-
oughly flushed with plain water, being careful to
clean those areas where mud and dirt may accu-
mulate. For additional information, see “Cleaning
exterior” in the “Appearance and care” section.
Windshield washer fluid*:Check that there is
an adequate amount of fluid in the reservoir.
8-4Maintenance and do-it yourself

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions that should be closely observed.
WARNING
• The EV (Electric Vehicle) system uses
high voltage up to approximately DC
400 volt. The system can be hot during
and after starting and when the vehicle
is shut off. Be careful of both the high
voltage and the high temperature.
Obey the labels that are attached to
the vehicle.
• Never disassemble, remove or replace
high-voltage parts and cables as well
as their connectors. High-voltage
cables are colored orange.
• Disassembling, removing or replacing
those parts or cables can cause severe
burns or electric shock that may result
in serious injury or death. The vehicle
high voltage system has no user ser-
viceable parts. Take your vehicle to the
NISSAN certified LEAF dealer for any
necessary maintenance.• Park the vehicle on a level surface,
apply the parking brake securely and
chock the wheels to prevent the ve-
hicle from moving. Push the P (Park)
position switch on the shift lever or
place the vehicle into the N (Neutral)
position.
• If you must work with the EV (Electric
vehicle) system is turned on, keep
hands, clothing, hair and tools away
from moving fans and any other mov-
ing parts.
• Make sure that the power switch is in
the OFF or LOCK position when per-
forming any part replacement or re-
pairs.
• 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 whenever
you work on your vehicle.
• Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
