When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions that should
be closely observed.
WARNING
• The EV system uses high voltage up
to approximately DC 400 volt. The
system can be hot during and af ter
starting and when the vehicle is shut
off. Be careful of both the high volt-
age and the high temperature. Obey
the labels that are attached to the
vehicle.
• Never disassemble, remove or re-
place high-voltage parts and cables
as well as their connectors. High-
voltage cables are colored orange.
• Disassembling, removing or replac-
ing 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 serviceable parts. It is recom-
mended that you visit a NISSAN cer-
tified 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 shif t 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
moving parts.
• Make sure that the power switch is in
the OFF or LOCK position when per-
forming any part replacement or
repairs.
• 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 when-
ever you work on your vehicle.
• Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary 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 cool-
ant. Improperly disposed coolant
and/or other vehicle fluids can dam-
age the environment. Always con-
form to local regulations for the dis-
posal of vehicle fluids.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the power switch is in the
ON position.
• Your vehicle is equipped with an au-
tomatic 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
injury, always disconnect the nega-
tive 12-volt battery cable before
working near the fan.
• Before performing any electrical
maintenance work on the vehicle
such as the battery, fuses or bulb re-
placement, confirm the following:
– The charge connector is removed
from the vehicle.

8-4Do-it yourself

When checking or replacement is required,
it is recommended that you visit a NISSAN
certified LEAF dealer for this service.
CAUTION
• Use only Genuine NISSAN Matic S ATF.
Do not mix with other fluids.
• Using reduction gear fluid other than
Genuine NISSAN Matic S ATF will
cause deterioration in driveability
and reduction gear durability, and
may damage the reduction gear,
which is not covered by the NISSAN
New Vehicle Limited Warranty. For additional brake fluid information, see
“Recommended fluids/lubricants and ca-
pacities” (P. 10-2).WARNING
• Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake system.
The use of improper fluids can dam-
age the brake system, and affect the
vehicle’s stopping ability.
• Clean the filler cap before removing.
• Brake fluid is poisonous and should
be stored carefully in marked con-
tainers out of the reach of children.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid
is spilled, immediately wash the sur-
face with water. Check the fluid level in the reservoir. If the
fluid is below the MIN line
OBor the brake
warning light illuminates, add Genuine
NISSAN Super Heavy Duty Brake Fluid or
equivalent DOT 3fluid up to the MAX line
OA.
If fluid must be added frequently, the sys-
tem should be checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service.

Electric shif t P (Park) position mecha-
nism:On a steep hill check that the vehicle
is held securely while the vehicle is in the P
(Park) position without applying any
brakes.
Parking brake: Check the parking brake
operation 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 position, it is recom-
mended that you visit a NISSAN certified
LEAF 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 conditions, 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
emits from 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.
12–volt battery (except for maintenance
free batteries)*: 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 condi-
tions require frequent checks of the 12–volt
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 EV system 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 levels are between the MAX and MIN
lines on the reservoir.
Coolant level*: Check the coolant level
when the high voltage parts are cold. Make
sure that the coolant level is between the
MAX and MIN lines on the reservoir.
Fluid leaks: Check under the vehicle for
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, check for
cause and have it corrected immediately.

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 and rotors: Check for wear,
deterioration and fluid leaks. Replace any
deteriorated or damaged parts
immediately.
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: Rotate tires at the specified
interval shown in the maintenance sched-
ule. When rotating tires, check for damage
and uneven wear. Replace if necessary.
Reduction Gear Oil: Visually inspect for
signs of leakage at specified intervals. 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 conditions
should 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.
