LI-ION BATTERY TEMPERATURE
GAUGE
The gauge indicates the temperature of the Li-ion
battery.
The temperature of the Li-ion battery is within the
normal range when the display is within the zone
1shown in the illustration.
The temperature of the Li-ion battery varies ac-
cording to the outside air temperature and driving
conditions.
NOTE:
•If the display indicates that the tempera-
ture of the Li-ion battery is near the red
zone end of the normal range, reduce ve-
hicle speed to decrease the temperature.
If the indicator is over the normal range,
the power provided to the traction motor
is reduced when the power limitation in-
dicator light is illuminated. Therefore the
vehicle is not as responsive when the ac-
celerator is depressed while the power
limitation light is illuminated. See “Power
limitation indicator light”.
•If the outside temperature is extremely
low, the Li-ion temperature gauge may not
display a temperature reading. The ve-
hicle may not be able to be put in the
READY to drive mode. Contact a NISSAN
certified LEAF dealer.
POWER METER
This meter displays the actual traction motor
power consumption
Aand the regenerative
brake power provided to the Li-ion battery
B.
The white dot
1in the display moves right or left
depending on demand.
The white dot moves to the right when power is
provided to the traction motor (Li-ion battery dis-
charges) .
The white dot moves to the left when power is
generated and provided to the Li-ion battery by
Instruments and controls2-7

the regenerative brake system (Li-ion battery
charging) .
The power meter also indicates if the power
provided to the motor is limited or if regenerative
braking is limited. When power or regenerative
braking is limited, the circles on the display
change from a double circle to a single circle
2.
Regenerative braking is automatically reduced
when the Li-ion battery is fully charged to prevent
the Li-ion battery from becoming overcharged.
Regenerative braking is also automatically re-
duced when the Li-ion 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 more regenerative braking is reduced the
more double circles change to single circles
If the Li-ion battery charge is low, power provided
to the traction motor is reduced. Motor output is
also limited if the Li-ion battery temperature is
high/low (indicated by the red/blue zones on the
Li-ion battery temperature gauge) or the Li-ion
battery charge level is low.
The more power provided to the traction motor is
reduced the more double circles change to
single circles.
DRIVING RANGE
The driving range1(miles or km) provides an
estimated distance that the vehicle can be driven
before recharging is necessary. The driving range
is constantly being calculated, based on the
amount of available Li-ion battery charge and the
actual power consumption average.
NOTE:
•The driving range display will flash when
the low battery charge warning light illu-
minates. Additionally, if you continue to
drive the vehicle in this state and the Li-
ion battery is close to being completely
discharged, “---” will be displayed. Charge
the Li-ion battery as soon as possible.
When the Li-ion battery is charged, the
original display will be restored.
•After the vehicle is charged, the displayed
driving range is calculated based on the
actual average energy consumption of the
previous driving. The displayed driving
range will vary every time the vehicle is
fully charged.
•The driving range will increases or de-
creases when the air conditioner, heater
or Li-ion battery warmer is turned on or
off, or the vehicle is shifted between D
(Drive) and ECO, or when any other acces-
sory is turned on or off based on driving.

LI-ION BATTERY AVAILABLE
CHARGE GAUGE
The gauge1indicates theapproximateavail-
able Li-ion battery charge to run the vehicle.
Charge the Li-ion battery before the display
reaches the bottom line.The low battery charge warning light
illu-
minates when the Li-ion battery available charge
gauge is getting low. Charge as soon as it is
convenient, preferably before the display reaches
the bottom line. When the display reaches the
bottom of the display and the low battery charge
light illuminated, there is a very small reserve of
Li-ion battery charge remaining.
NOTE:
•The number of segments illuminated on
the Li-ion battery available charge gauge
is determined by the available charge and
the amount of charge the Li-ion battery is
capable of storing at the current tempera-
ture.
•Temperature affects the amount of charge
the Li-ion battery is capable of storing.
The Li-ion battery is capable of storing
less power when the Li-ion battery tem-
perature is cold. The Li-ion battery is ca-
pable of storing more power when the
Li-ion battery is warm. The number of seg-
ments illuminated on the Li-ion battery
available charge gauge can change based
on the amount of power the Li-ion battery
is capable of storing. For example, when
the Li-ion battery becomes colder, moresegments on the Li-ion battery available
charge gauge illuminate because the
available charge is a greater percentage
of the Li-ion battery’s capability of storing
power. When the Li-ion battery becomes
warmer, less segments on the Li-ion bat-
tery available charge gauge illuminate be-
cause the remaining energy is a lower
percentage of the Li-ion battery’s capabil-
ity of storing power.

LI-ION BATTERY CAPACITY LEVEL
GAUGE
This gauge indicates the amount of charge the
Li-ion battery is capable of storing.
When the capacity of the Li-ion battery de-
creases with age and usage, the level of the
gauge will also decrease.
OUTSIDE AIR TEMPERATURE
The outside air temperature is displayed in °F or
°C.
The display may differ from the actual outside
temperature displayed on various signs or bill-
boards.
ECO INDICATOR
The ECO indicator displays how economically
the vehicle is being operated.
The meter display is affected by the following
conditions:
• Accelerator pedal operation.
• Brake pedal operation.
• Driving conditions.
• Traffic conditions.
• Heater and air conditioner usage.

• Time the vehicle is not moving while the vehicle
is in the READY to drive mode and accessories
are on.
Instant ECO driving level
The instant ECO driving level
1is displayed by
the number of bars that increase (more economi-
cal driving) or decrease (less economical driving)
depending on vehicle operation.
Long term ECO driving level
Long term ECO driving is indicated by ECO
TREE symbols. The longer the vehicle is operated
economically, the more segments of the large
ECO TREE symbol
2are displayed. When all of
the segments of the large ECO TREE symbol are
displayed, a small ECO TREE indicator
3is also
displayed, and the large ECO TREE symbol dis-
play is reset. The longer the vehicle is operated
economically, the more small ECO TREE sym-
bols are displayed. The ECO TREE symbols that
were illuminated while driving will turn off when
the vehicle power is turned off. The ECO TREE
symbols are stored in the navigation system to
show long term efficient vehicle operation.To increase the ECO driving level and for infor-
mation about driving the vehicle efficiently, see
“Improve driving range” in the “EV overview”
section.
