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 that
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 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*: Check the fluid level in each
cell.
It should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
12-volt battery fluid level.
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
thoroughly flushed with plain water, being care-
ful to clean those areas where mud and dirt may
accumulate. For additional information, see
“Cleaning exterior” in the “7. Appearance and
care” section.
Windshield washer fluid*: Check that there is
an adequate amount of fluid in the reservoir.

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
battery.

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.

WARNING
The tire replacement indicator is not a
substitute for regular tire checks, in-
cluding tire pressure checks. See
“Changing wheels and tires” in the “8.
Maintenance and do-it-yourself” sec-
tion. Many factors including tire infla-
tion, alignment, driving habits and road
conditions affect tire wear and when
tires should be replaced. Setting the
tire replacement indicator for a certain
driving distance does not mean your
tires will last that long. Use the tire
replacement indicator as a guide only
and always perform regular tire checks.
Failure to perform regular tire checks,
including tire pressure checks could
result in tire failure. Serious vehicle
damage could occur and may lead to a
collision, which could result in serious
personal injury or death.
2. 3. 4. “Other” indicator
These indicators appears when the customer
set distance comes for checking or replacing
maintenance items other than the tires. Other
maintenance items can include such things as
the tire rotation. You can set or reset the
distance for checking or replacing the items.
(See “Trip computer” earlier in this section.) For
scheduled maintenance items and intervals, see
your NISSAN Service and Maintenance Guide.

CAUTION
.Be sure to carry the Intelligent Key
with you when operating the vehi-
cle.
. Never leave the Intelligent Key in
the vehicle when you leave the
vehicle.
The Intelligent Key is always communicating with
the vehicle because it receives radio waves. The
Intelligent Key system transmits weak radio
waves. Environmental conditions may interfere
with the operation of the Intelligent Key system
under the following operating conditions.
. When operating near a location where
strong radio waves are transmitted, such
as a TV tower, power station or broad-
casting station.
. When in possession of wireless equipment,
such as a cellular phone, transceiver or CB
radio.
. When the Intelligent Key is in contact with or
covered by metallic materials.
. When any type of radio wave remote control
is used nearby. .
When the Intelligent Key is placed near an
electric appliance such as a personal
computer.
. When the vehicle is parked near a parking
meter.
In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depending
on the operating conditions, the battery’s life is
approximately 2 years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is almost
discharged, firmly apply the foot brake and
touch the power switch with the Intelligent Key.
Then push the power switch while depressing
the brake pedal within 10 seconds after the
chime sound.
Since the Intelligent Key is continuously receiv-
ing radio waves, if the key is left near equipment
that transmits strong radio waves, such as
signals from a TV or personal computer, the
battery life may become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replacement”
in the “8. Maintenance and do-it-yourself”
section. Pay special attention that the vehicle battery is
not completely discharged.
As many as 4 Intelligent Keys can be registered
and used with one vehicle. For information about
the purchase and use of additional Intelligent
Keys, contact a NISSAN certified LEAF dealer.

inflated tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds.
Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspect the tires for wear and damage. See
“Wheels and tires” in the “8. Maintenance and
do-it-yourself” section of this manual.
If a tire rapidly loses air pressure or “blows-out”
while driving maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
