coolant temperature NISSAN LEAF 2021 Owner´s Manual

•When using a wheel without the
TPMS such as a spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have the
system checked. It is recommended
that you visit a NISSAN certified LEAF
dealer as soon as possible for tire re-
placement and/or system resetting.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
• If the vehicle is being driven at
speeds of less than 16 mph (25 km/h),
the TPMS may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
Master warning light
There are two types of master warning
lights: yellow and red. These lights illumi-
nate if any warning lights or indicator lights
are illuminated or if various vehicle infor-
mation warnings appear in the vehicle in-
formation display.
This light illuminates when a yellow warn-
ing light within the vehicle information dis-
play is illuminated or when a message is
displayed on the vehicle information
display.
Power limitation
indicator light
When the power limitation indicator light is
illuminated, the power provided to the trac-
tion motor is reduced. Therefore the ve-
hicle is not as responsive when the accel-
erator is depressed while the power
limitation light is illuminated.
When this light comes on, the warning dis-
play appears within the vehicle information
display. Follow the instructions provided on
the vehicle information display.
This light illuminates in the following
conditions. • Li-ion battery available charge is ex-
tremely low
• Li-ion battery temperature is very low (approximately −4°F (−20°C)
• When the temperature of the EV system is high (motor, inverter, coolant system,
Li-ion battery etc.)
• When the EV system has a malfunction.
If the low battery charge indicator is illumi-
nated, charge the Li-ion battery as soon as
possible.
If this indicator illuminates because the Li-
ion battery is cold due to low outside tem-
peratures, move the vehicle to a warmer
location. The Li-ion battery temperature
may be increased by charging the Li-ion
battery.
If the light illuminates when the EV system
becomes hot due to continuous hill climb-
ing, either continue driving at a slower safe
speed or stop the vehicle in a safe location.
If this indicator does not turn off, have the
system checked. It is recommended that
you visit a NISSAN certified LEAF dealer for
this service.
2-22Instruments and controls

CAUTION
To prevent damage to the Li-ion bat-
tery: Do not store the vehicle in tem-
peratures below -13°F (-25°C) for over
seven days. If the outside temperature
is -13°F (-25°C) or less, the Li-ion battery
may freeze and it cannot be charged or
provide power to run the vehicle. Move
the vehicle to a warm location.
NOTE:
• Connect the charger to the vehicle and place the power switch in the OFF po-
sition when parking the vehicle if tem-
peratures may go below -4°F (-20°C).
For models with 40 kWh battery
model, this provides external power to
the Li-ion battery warmer (if so
equipped) when it operates and does
not discharge the Li-ion battery. Ve-
hicle driving range is reduced if the Li-
ion battery warmer (if so equipped) op-
erates (Li-ion battery temperature
approximately -4°F (-20°C) or colder)
while driving the vehicle. You may need
to charge the Li-ion battery sooner
than in warmer temperatures.
• The Li-ion battery requires more time to charge when the Li-ion battery
warmer (if so equipped) operates. • The predicted charging time displayed
on the meter and navigation system (if
so equipped) increases when the Li-ion
battery warmer (if so equipped)
operates.
• Vehicle range may be substantially re- duced in extremely cold conditions (for
example under -4°F (-20°C)).
• Using the climate control system to heat the cabin when outside tempera-
ture is below 32°F (0°C) uses more elec-
tricity and affects vehicle range more
than when using the heater when the
temperature is above 32°F (0°C).
• Climate control performance is re- duced when using the Climate Ctrl.
Timer or Remote Climate Control while
the Li-ion battery warmer (if so
equipped) operates (for models with
40 kWh battery model). Set only the
charging timer [End Time] when charg-
ing in cold weather. The vehicle auto-
matically determines when to start
charging to fully charge the Li-ion bat-
tery, even if the Li-ion battery warmer
operates. Charging ends before the set
end time if the Li-ion battery is fully
charged.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting
it into the key hole or use the remote key-
less entry key fob.
ANTIFREEZE
In the winter when it is possible that the
outside temperature will drop below 32°F
(0°C), check the antifreeze to ensure proper
winter protection. For additional informa-
tion, see “Cooling system” (P. 8-5).
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, see “12-volt battery” (P. 8-9).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system. Refill
before operating the vehicle. For additional
information, see “Cooling system” (P. 8-5).

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 recom-
mended that you visit a NISSAN cer-
tified LEAF dealer for any necessary
maintenance. •
Park the vehicle on a level surface,
apply the parking brake securely and
chock the wheels to prevent the ve-
hicle from moving. Push the P (Park)
position switch on the shif t lever or
place the vehicle into the N (Neutral)
position.
• If you must work with the EV (Electric
Vehicle) system is turned on, keep
hands, clothing, hair and tools away
from moving fans and any other
moving parts.
• Make sure that the power switch is in
the OFF or LOCK position when per-
forming any part replacement or
repairs.
• It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle.
• Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flames and
sparks away from the 12-volt battery.
CAUTION
• Do not work under the hood while
the motor compartment is hot. Push
the power switch in the OFF position
and wait until it cools down.
• Avoid direct contact with used cool-
ant. Improperly disposed coolant
and/or other vehicle fluids can dam-
age the environment. Always con-
form to local regulations for the dis-
posal of vehicle fluids.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the power switch is in the
ON position.
• Your vehicle is equipped with an au-
tomatic cooling fan. It may come on
at any time without warning, even if
the power switch is not in the ACC, ON
or READY to drive position. To avoid
injury, always disconnect the nega-
tive 12-volt battery cable before
working near the fan.
• Before performing any electrical
maintenance work on the vehicle
such as the battery, fuses or bulb re-
placement, confirm the following:
– The charge connector is removed
from the vehicle.
MAINTENANCE PRECAUTIONS
8-2Do-it yourself

Electric shif t P (Park) position mecha-
nism:On a steep hill check that the vehicle
is held securely while the vehicle is in the P
(Park) position without applying any
brakes.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a steep hill with only the
parking brake applied. If the parking brake
cannot keep a vehicle position, it is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
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 webbing 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 all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
emits from the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically.
12–volt battery (except for maintenance
free batteries)*: Check the fluid level in
each cell. The fluid should be at the bottom
of the filler opening. Vehicles operated in
high temperatures or under severe condi-
tions require frequent checks of the 12–volt
battery fluid level.
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 levels are 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.
