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.

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.

CHECKING COOLANT LEVEL
Check the coolant levelin the reservoir when
the high voltage parts are cold. If the coolant
level is below the MIN level
*2, open the
reservoir cap and add coolant up to the MAX
level
*1. If the reservoir is empty, check the
coolant level in the coolant tank when the high
voltage parts are cold. If there is insufficient
coolant in the coolant tank, fill the coolant tank
with coolant up to the reservoir cap opening and
also add it to the reservoir up to the MAX level
*1.
Tighten the cap securely after adding coolant. If the cooling system frequently requires
coolant, have it checked by a NISSAN
certified LEAF dealer.
CHANGING COOLANT
Major cooling system repairs should be per-
formed by a NISSAN certified LEAF dealer. The
service procedures can be found in the appro-
priate NISSAN Service Manual.
Improper servicing can result in reduced
heater performance.
