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.

washer fluid into the reservoir opening.
Add a windshield-washer solvent to the
reservoir for better cleaning. In the winter
season, add a windshield-washer anti-
freeze. Follow the manufacturer’s instruc-
tions for the mixture ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of windshield-washer fluid.
Recommended fluid:
Genuine NISSAN Windshield-Washer Con-
centrate Cleaner & Antifreeze or equivalent
CAUTION
• Do not substitute antifreeze coolant
for windshield-washer solution. This
may result in damage to the paint. •

reservoir with windshield-washer
fluid concentrates at full strength.
Some methyl alcohol based
windshield-washer fluid concen-
trates may permanently stain the
grille if spilled while filling the
windshield-washer reservoir.
• Pre-mix windshield-washer fluid
concentrates with water to the
manufacturer’s recommended levels
before pouring the fluid into the
windshield-washer reservoir. Do not
use the windshield-washer reservoir
