CAUTION
• NEVER remove dirt, sand or other de-
bris from the passenger compartment
by washing it out with a hose. Remove
dirt with a vacuum cleaner.
• Never allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle as this may

Chemicals used for road surface deicing are
extremely corrosive. They accelerate corrosion
and deterioration of underbody components
such as the brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be cleaned
periodically.
For additional protection against rust and corro-
sion, which may be required in some areas, con-

or wear if they do not wipe properly.
Inside vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming scheduled maintenance, cleaning the ve-
hicle, etc.
Accelerator pedal:Check the pedal for smooth
operation and make sure that the pedal does not
catch or require uneven effort. Keep the floor mat
away from the pedal.
Brake pedal:Check the pedal for smooth op-
eration and make sure that it has the properdistance under it when depressed fully. Check
the brake booster function. If the brake pedal
suddenly goes down further than normal, the
pedal feels spongy or the vehicle seems to take
longer to stop, contact a NISSAN certified LEAF
dealer immediately. Keep the floor mat away from
the pedal.
Brakes:Check that the brakes do not pull the
vehicle to one side when applied.
Electric shift P (Park) position mechanis-
m:On a steep hill, check that the vehicle is held
securely while the vehicle is in the P (Park) posi-
tion without applying the brakes.
Parking brake:Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a steep hill with only the parking brake applied.
If the parking brake cannot keep a vehicle posi-
tion contact a NISSAN certified LEAF dealer.
Seat:Check seat position controls such as the
seat adjusters, seatback recliners, etc. to ensure
that they operate smoothly and that all latches
lock securely in every position. Check that the
head restraints/headrests move up and down
smoothly and that the locks (if so equipped) hold
securely in all latched positions.
Maintenance and do-it yourself8-3

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 web-
bing for cuts, fraying, wear or damage.

the wipers and washers operate properly and
that the wipers do not streak.
Under hood and vehicle
The maintenance items listed here should be
checked periodically.
12-volt battery (for serviceable battery)*:
Check the fluid level in each cell.
It should be between the MAX and MIN lines.
Vehicles operated in high temperatures or undersevere conditions require frequent checks of the
12-volt battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic ac-
cessories that consume battery 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 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
it with safety stands.
• Keep smoking materials, flames and
sparks away from the 12-volt battery.
CAUTION
• Do not work under the hood while the
motor compartment is hot. Push the
power switch in the OFF position and
wait until it cools down.
• Avoid direct contact with used coolant.
Improperly disposed coolant and/or
other vehicle fluids can damage the
environment. Always conform to local
regulations for the disposal of vehicle
fluids.
• Never connect or disconnect the bat-
tery or any transistorized component
while the power switch is in the ON
position.
• Your vehicle is equipped with an auto-
matic cooling fan. It may come on at
any time without warning, even if the
power switch is not in the ACC, ON or
READY to drive position. To avoid in-
jury, always disconnect the negative
12-volt battery cable before working
near the fan.
• Before performing any electrical main-
tenance work on the vehicle such as
the battery, fuses or bulb replacement,
confirm the following:
– The charge connector is removed
from the vehicle.
