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 manufacture'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 NISSAN Ser-
vice and Maintenance Guide.
COOLING SYSTEM
8-8Maintenance and do-it yourself

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 cool-
ant.
For additional information on the location
of the coolant reservoir, refer to “Motor
compartment check locations” in this sec-
tion.
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.

12-VOLT BATTERY
8-12Maintenance and do-it yourself

NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-tronic accessories that consume bat-
tery power when the EV system is not
running (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health
WARNING
• Do not expose the 12-volt battery to
flames or electrical sparks. Hydrogen
gas generated by the 12-volt battery
is explosive. Do not allow 12-volt bat-
tery fluid to contact your skin, eyes,
fabrics or painted surfaces. Af ter
touching a 12-volt battery or 12-volt
battery cap, do not touch or rub your
eyes. Thoroughly wash your hands. If
the acid contacts your eyes, skin or
clothing, immediately flush with wa-
ter for at least 15 minutes and seek
medical attention. •
Do not operate the vehicle if the fluid
in the 12-volt battery is low. Low 12-
volt battery fluid can cause a higher
load on the 12-volt battery which can
generate heat, reduce battery life,
and in some cases lead to an
explosion.
• When working on or near a 12-volt
battery, always wear suitable eye
protection and remove all jewelry.
• 12-volt battery posts, terminals and
related accessories contain lead and
lead compounds. Wash hands af ter
handling.
• Keep the 12-volt battery out of the
reach of children. 1. Remove the vent caps with a screw-
driver as shown. Use a cloth to protect
the battery case.
2. Check the fluid level in each cell. If it is necessary to add fluid, add only distilled
water to bring the level up to the bottom
of the filler opening. Do not overfill.Re-
install the vent caps.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the 12-volt battery fluid level.
