2019 NISSAN LEAF radiator

•Less deceleration is provided by the re-
generative brake system when the Li-
ion battery is fully charged. The regen-
erative brake is automatically reduced
when the Li-ion battery is fully charged
to prevent the Li-ion battery from be-
coming overcharged. The regenerative
brake is also automatically reduced
when the battery temperature is high/
low (indicated by the red/blue zones on
the Li-ion battery temperature gauge)
to prevent Li-ion battery damage.
• The brake pedal should be used to slow
or stop the vehicle depending on traffic
or road conditions. The vehicle brakes
are not affected by the regenerative
brake system operation.NOISE AND VIBRATION
You might experience the following noise
or vibration as a normal characteristic of
this vehicle:
• Traction motor noise from the motor
compartment.
• Water pump and radiator fan noise while charging.
• Compressor and radiator fan noise when the Climate Ctrl. Timer or remote climate
control (models with Navigation System)
is used.
• Relay operation noise and vibration at start-up and shut-down of the EV system
(power switch placed in the ON and OFF
position).
• Approaching Vehicle Sound for Pedestri- ans (VSP). This section provides a brief explanation
for the most important LEAF functions. For
additional information, refer to the specific
sections of this manual for detailed expla-
nations of the vehicle features and opera-
tion.
CHARGING THE LI-ION BATTERY
WARNING
The EV system uses a high voltage cur-
rent. Failure to follow the proper han-
dling instructions may cause serious
injury or death. Be sure to read the
“Charging” section and follow the pro-
cedures and guidelines described.

5-138Starting and driving

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.
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 high voltage parts are cold. Make
sure that the coolant level is between the
MAX and MIN lines on the reservoir. Fluid leaks:
Check under the vehicle for
water or other fluid leaks af ter the vehicle
has been parked for a while. Water dripping
from the air conditioner af ter use is normal.
If you should notice any leaks, check for
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
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, re-
fer to “Cleaning exterior” in the “Appearance
and care” section of this manual.
Windshield-washer fluid*: Check that
there is an adequate amount of fluid in the
reservoir. When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions that should
be closely observed.
WARNING
• The EV system uses high voltage up to approximately DC 400 volt. The
system can be hot during and af ter
starting and when the vehicle is shut
off. Be careful of both the high volt-
age and the high temperature. Obey
the labels that are attached to the
vehicle.
• Never disassemble, remove or re- place high-voltage parts and cables
as well as their connectors. High-
voltage cables are colored orange.
• Disassembling, removing or replac- ing those parts or cables can cause
severe burns or electric shock that
may result in serious injury or death.
The vehicle high-voltage system has
no user serviceable parts. It is rec-
ommended that you visit a NISSAN
certified LEAF dealer for any neces-
sary maintenance.
MAINTENANCE PRECAUTIONS
Maintenance and do-it yourself8-5

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 tank cap when the motor compartment is
hot. Wait until the motor compart-
ment cool down.
• The coolant tank is equipped with a special type coolant tank cap. To
prevent damage to the motor com-
partment, use only a Genuine
NISSAN coolant tank cap.
CAUTION
•
Never use any additives in the coolant
such as radiator sealer in the cooling
system. This may cause damage to
electrical equipment such as the mo-
tor 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 oper-
ate your vehicle, add Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
concentrate following the directions
on the container. If and equivalent
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is
used, follow the coolant manufac-
ture's instructions to maintain mini-
mum antifreeze protection to −34°F
(−37°C). The use of other types of cool-
ant solutions other than Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) or equivalent 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),
including Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the use
of non-distilled water will reduce the
life expectancy of the factory-filled
coolant. For additional information,
refer to the NISSAN Service and Main-
tenance Guide.
