• Do not cover or attach stickers, or installany accessory near the sensors. This
could block sensor signals, and/or cause
failure or malfunction.
• Do not attach metallic objects near the radar sensor (brush guard, etc.). This
could cause failure or malfunction.
• Do not place reflective materials, such as white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
detection capability.
• Do not alter, remove or paint the front bumper. Before customizing or restoring
the front bumper, it is recommended that

Starting and driving5-131

The cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue)
and 50% water to provide year-round anti-
freeze and coolant protection. The anti-
freeze solution contains rust and corrosion
inhibitors. Additional cooling system addi-
tives are not necessary.
WARNING
• Never remove the coolant reservoir
cap when the motor compartment is
hot. Wait until the motor compart-
ment cools down.
• The coolant reservoir is equipped
with a pressure type coolant reser-
voir cap. To prevent damage to the
motor compartment, use only a
Genuine NISSAN coolant reservoir
cap.
CAUTION
• Never use any additives in the cool-
ant such as radiator sealer in the
cooling system. This may cause
damage to electrical equipment
such as the motor and inverter. •
When adding or replacing coolant, be
sure to use only a Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent. Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to −34°F (−37°C) . If additional
freeze protection is needed due to
the weather conditions where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the di-
rections on the container. If an
equivalent coolant other than Genu-
ine NISSAN Long Life Antifreeze/
Coolant (blue) is used, follow the
coolant manufacturer's instructions
to maintain minimum antifreeze
protection to −34°F (−37°C). The use
of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equiva-
lent may damage the cooling
system. •
The life expectancy of the factory-fill
coolant is 125,000 miles (200,000
km) or 15 years. Mixing any other type
of coolant other than Genuine
NISSAN Long Life Antifreeze/Coolant
(blue)(or equivalent coolant), includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the
use of non-distilled water may re-
duce the life expectancy of the
factory-filled coolant. For additional
information, refer to the “Mainte-
nance and schedules” section of this
manual.
COOLING SYSTEM
Do-it yourself8-5

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
OB,
open the reservoir cap and add coolant up
to the MAX level
OA. If the reservoir is empty,
check the coolant level in the coolant res-
ervoir when the high-voltage parts are
cold. If there is insufficient coolant in the
coolant reservoir, fill the coolant reservoir
with coolant up to the reservoir cap open-
ing and also add it to the reservoir up to the
MAX level
OA. Tighten the cap securely af ter adding
coolant.
For additional information on the location
of the coolant reservoir, see “Motor com-
partment check locations” (P. 8-4).
If the cooling system frequently requires
coolant, it is recommended that you visit
a NISSAN certified LEAF dealer.
CHANGING COOLANT
It is recommended that major cooling sys-
tem repairs should be performed by a
NISSAN certified LEAF dealer. The service
procedures can be found in the appropri-
ate NISSAN Service Manual.
Improper servicing can result in reduced
heater performance.
WARNING
• To avoid the danger of being scalded,
never change the coolant when the
motor compartment is hot.
• Never remove the coolant reservoir
cap when the motor compartment is
hot. Serious burns could be caused
by high-pressure fluid escaping from
the radiator.
• Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand
cleaner as soon as possible.
• Keep coolant out of reach of children
and pets.
Coolant must be disposed of properly.
Check your local regulations.

Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan and frame. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “Cleaning exterior” (P. 7-2).
Windshield-washer fluid*: Check that
there is an adequate amount of fluid in the
reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, see “Gen-
eral maintenance” (P. 9-2).
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual.

MAINTENANCE ITEMS
EV System Charging Port*: Check the
charging port for any signs of contamina-
tion, dust, sand etc. Charging Port Sealing Cap*:
Use only
compressed air with proper eye protection
to clean any contamination from the seal-
ing cap.
EV Battery Usage Report: To maximize
the life of your Li-ion battery, have the EV
Battery Usage Report generated and re-
viewed with you. Review of the EV Battery
Usage Report is required as a condition of
EV battery warranty. Refer to your 2021
LEAF warranty information booklet for de-
tails. Both the 12 month and 24 month in-
spections will be performed by your
NISSAN certified LEAF dealer at no cost to
the vehicle owner.
Coolant: Replace coolant at the interval
specified below. When adding or replacing
coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (Blue)
or equivalent with the proper mixture. (Re-
fer to the Owner’s Manual to determine the
proper mixture for your area.) The recom-
mended service interval of the factory fill
coolant is 125,000 miles (200,000 km) or 15
years, whichever comes first. Subsequent
replacement of Genuine NISSAN Long Life
Antifreeze/Coolant (Blue) should occur ev-
ery 75,000 miles (120,000 km) or 5 years
whichever comes first.
