2014 NISSAN LEAF radiator

Li-ion battery is fully charged to prevent
the Li-ion battery from becoming over-
charged. Regenerating brake is also auto-
matically reduced when the battery tem-
perature is high/low (indicated by the red/
blue zones on the Li-ion battery
temperature gauge) to prevent Li-ion bat-
tery 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 regenerative brake system
operation.NOISE AND VIBRATION
You might experience the following noise or vi-
bration as a normal characteristic of this vehicle.
• Traction motor noise from motor compartment.
• Water pump and radiator fan noise while charg-
ing.
• 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 (Electric Vehicle) sys-
tem (power switch placed in the ON and OFF
position) .
• Approaching Vehicle Sound for Pedestrians
(VSP) .This section provides a brief explanation for the
most important LEAF functions. Refer to the spe-
cific sections of this manual for detailed explana-
tions of the vehicle features and operation.
CHARGING THE LI-ION BATTERY
WARNING
The EV (Electric Vehicle) system uses a
high voltage current. Failure to follow the
proper handling instructions may cause
serious injury or death. Be sure to read
the “Charge” section and follow the pro-
cedures and guidelines described.
LIFE WITH AN EV (SCENE GUIDE)
EV-10EV Overview

Seat belts:Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing 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 suffi-
cient 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 (for serviceable battery)*:
Check the fluid level in each cell.
It should be between the MAX and MIN lines.
Vehicles operated in high temperatures or undersevere conditions require frequent checks of the
12-volt battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic ac-
cessories that consume battery power when
the engine 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 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 thor-
oughly flushed with plain water, being careful to
clean those areas where mud and dirt may accu-
mulate. For additional information, see “Cleaning
exterior” in the “Appearance and care” section.
Windshield washer fluid*:Check that there is
an adequate amount of fluid in the reservoir.
8-4Maintenance and do-it yourself

The cooling system is filled at the factory with a
pre-diluted mixture of 50% genuine NISSAN
Long Life Antifreeze/Coolant (blue) and 50% wa-
ter to provide year-round anti-freeze and coolant
protection. The antifreeze solution contains rust
and corrosion inhibitors. Additional cooling sys-
tem additives are not necessary.
WARNING
• Never remove the coolant tank cap
when the motor compartment is hot.
Wait until the motor compartment cool
down.
• The coolant tank is equipped with a
special type coolant tank cap. To pre-
vent damage to the motor compart-
ment, 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 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 directions
on the container. If and equivalent
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is
used, follow the coolant manufacture’s
instructions to maintain minimum an-
tifreeze protection to −34°F (−37°C) .
The use of other types of coolant solu-
tions 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. Refer to the NISSAN Service
and Maintenance Guide for more de-
tails.
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
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 tankwhen 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 cer-
tified 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 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 tank 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.
