maintenance.
. Park the vehicle on a level surface,
apply the parking brake securely
and chock the wheels to prevent
the vehicle from moving. Push the P
position switch on the selector 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
performing 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
necessary to work under the vehicle,
support it with safety stands. .
Keep smoking materials, flames
and sparks away from the 12-volt

position to prevent the 12-volt bat-
tery automatically being charged by
the Li-ion battery. See “Charging
the 12-volt battery” in the “EV.
Overview” section.
This “8. Maintenance and do-it-yourself” section
gives instructions regarding only those items
that are relatively easy for an owner to perform.
A genuine NISSAN Service Manual is also
available. See “Owner’s Manual/Service Manual
order information” in the “9. Technical and
consumer information” section.
You should be aware that incomplete or
improper servicing may result in operating
difficulties and could affect your warranty cover-
age. If in doubt about any servicing, we
recommend that it be done by a NISSAN
certified LEAF dealer.

1. Remove the cell plugs*A.
2. Add distilled water up to the UPPER LEVEL
*1line.
If the side of the 12-volt battery is not clear,
check the distilled water level by looking
directly above the cell; the condition
*1
indicates OK and the condition*2needs
more to be added.
3. Tighten cell plugs
*A.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
12-volt battery fluid level.
JUMP STARTING
Jump starting provides power to the 12 volt
system to allow the electrical systems to
operate. The electrical systems must be operat-
ing to allow the Li-ion battery to be charged.
Jump starting does not charge the Li-ion battery.
The Li-ion battery must be charged before the
vehicle can be driven.
If jump starting is necessary, see “Jump starting”
in the “6. In case of emergency” section. If the
power switch does not switch to READY to drive
position by jump starting, the 12-volt battery
may have to be replaced. Contact a NISSAN
certified LEAF dealer.

the 12-volt battery.
. Avoid using the power outlet when
the air conditioner, headlights or
rear window defroster are on.
. This power outlet is not designed
for use with a cigarette lighter unit.
. Push the plug in as far as it will go.
If good contact is not made, the plug
may overheat or the internal tem-
perature fuse may open.
. Before inserting or disconnecting a
plug, make sure that the electrical
accessory being used is turned OFF.
. When not in use, be sure to close
the cap. Do not allow water to
contact the outlet.

EMERGENCY SHUT-OFF SYSTEM
The emergency shut-off system is activated and
the high-voltage system automatically turns off in
the following conditions:
- Front and side collisions in which the air bags
are deployed.
- Certain rear collisions.
- Certain EV (Electric Vehicle) system malfunc-
tions
For the above collisions and certain other EV
(Electric Vehicle) system malfunctions, the
READY to drive indicator light will turn off. See
“Warning/indicator lights and audible remin-
ders” in the “2. Instruments and controls”
section.
The emergency shut-off activates for the above
collisions to minimize risk of an event that could
cause injury or an accident. If the emergency
shut-off system activates, the EV system may
not be switched to READY to drive position,
contact a NISSAN certified LEAF dealer. Even if
the power switch is switched to READY to drive
position, the system may shut-off suddenly.
Therefore, drive cautiously to the nearest
NISSAN certified LEAF dealer or contact a
NISSAN certified LEAF dealer as soon as
possible.WARNING
.Pay special attention to pedes-
trians. Because there is no engine
noise, pedestrians may not know
the vehicle is approaching, moving
or about to move, and may step into
the path of vehicle travel.
. When leaving the vehicle, be sure to
turn off the EV (Electric Vehicle)
system.
. Be sure to push the P (Park) posi-
tion switch on the selector lever and
apply the parking brake when park-
ing because the vehicle can move
when the READY to drive indicator
light is ON. When the READY to
drive indicator light is ON, do not
leave your vehicle in a shift position
other than the P (Park) position.
. Keep the brake pedal depressed
until you are ready to drive. When
the vehicle is in the D (drive) posi-
tion or ECO or R (reverse) position,
if you release the brake pedal and
do not depress accelerator, the
vehicle will creep and may start
abruptly. This may cause serious injury or death.
NOTE:
. The vehicle cannot run with a dis-
charged Li-ion battery. Repeated accel-
eration consumes more power from the
Li-ion battery than driving at a steady
speed.
. This vehicle is equipped with a regen-
erative brake system. The primary pur-
pose of regenerative brake system is to
provide some power to recharge the Li-
ion battery and extend driving range. A
secondary benefit is “engine braking”
that operates based on Li-ion battery
conditions.
. In the D (Drive) position, when the
accelerator pedal is released, the re-
generative brake system provides
some deceleration.
. When you put the shift selector in the
ECO position and take your foot off the
accelerator pedal, more regenerative
brake is applied than in the D (Drive)
position.
. Less deceleration is provided by the
regenerative brake system when the Li-

CHARACTERISTICS

ion battery is fully charged. Regenera-
tive brake is automatically reduced
when the Li-ion battery is fully charged
to prevent the Li-ion battery from
becoming overcharged. Regenerating
brake is also automatically reduced
when the battery temperature is high/
low (indicated by the red/blue zones
on the Li-ion battery temperature
gauge) to prevent Li-ion battery da-
mage.
. The brake pedal should be used to
slow or stop the vehicle depending on
traffic or road conditions. The vehicle
brakes are not affected by regenerative
brake system operation.
NOISE AND VIBRATION
You might experience the following noise or
vibration as a normal characteristic of this
vehicle.
.Traction motor noise from motor compart-
ment.
. Noise and vibration when releasing and
applying the electric parking brake.
. Water pump and radiator fan noise while
charging. .
Compressor and radiator fan noise when the
Climate Ctrl. Timer or remote climate control
is used.
. Relay operation noise and vibration at start-
up and shut-down of the EV (Electric
Vehicle) system (power switch placed in
the ON and OFF position) .
. Approaching Vehicle Sound for Pedestrians
(VSP) .
WARNING
The EV (Electric Vehicle) system uses a
high voltage current. Failure to follow
the proper handling instructions may
cause serious injury or death. Be sure
to read the “CH. Charging” section and
follow the procedures and guidelines
described.

WARNING
Your vehicle contains a sealed Li-ion
high voltage battery. If the Li-ion bat-
tery is disposed of improperly, there is a
risk of severe burns and electrical
shock that may result in serious injury
or death and there is also a risk of
environmental damage.
