High Beam Assist indicator
light (if so equipped)
The indicator light illuminates when the
headlights come on while the headlight
switch is in the AUTO position with the high
beam selected. This indicates that the high
beam assist system is operational. For ad-
ditional information, refer to “Headlight
beam select” in this section.
High beam indicator light
(blue)
This light illuminates when the headlight
high beam is on and goes out when the low
beam is selected.
Plug-in indicator light
This light illuminates when the charge con-
nector is connected to the vehicle and
blinks during charging.
NOTE:
If the charge connector is connected to
the vehicle, the power switch cannot be
placed in the READY to drive position.
Power limitation indicator
light
When the power limitation indicator light
is illuminated, the power provided to the
traction motor is reduced. Therefore the
vehicle is not as responsive when the
accelerator 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 condi-
tions.
• Li-ion battery available charge is ex-tremely low
• Li-ion battery temperature is very lowj (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.
The indicator illuminates when a part in the
EV system has malfunctioned. If the indica-
tor illuminates in a situation other than
those described above, or if it does not turn
off, there may be a system malfunction.
Have the system checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service.
Instruments and controls2-25

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, refer to “Cooling system” in the “Main-
tenance and do-it-yourself ” section of this
manual.
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, refer to “12-volt battery” in the
“Maintenance and do-it-yourself ” section
of this manual.
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, refer to “Cooling system” in the
“Maintenance and do-it-yourself ” section
of this manual.
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads, NISSAN
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for the tire type, size,
speed rating and availability information.
For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires.Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may
be poorer than that of non-studded
snow tires.
Tire chains may be used. For additional in-
formation, refer to “Tire chains” in the “Main-
tenance and do-it-yourself ” section of this
manual.SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-
move ice and snow from the windows and
wiper blades.
• A shovel to dig the vehicle out of snow-drif ts.
• Extra windshield-washer fluid to refill the reservoir tank.
Starting and driving5-155

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.
