ergy (mileage) (4) to show a longer distance
than the vehicle was driven or the current
energy economy (2) to show “99.9
miles/kWh.”
When the
button is pressed while the
ECO Drive Report is shown, the display
switches to the timer display. Either display
will continue to show for another 30 sec-
onds af ter the button is pressed. If the
doors are locked af ter placing the power
switch in the OFF position, the display turns
off before the preset time.
In the “Settings” menu, you can program
the ECO Drive Report to not appear when
the power switch is placed in the OFF posi-
tion. For additional information, see “Ve-
hicle information display” (P. 2-26). The vehicle range varies depending upon
the following factors:
• Speed
• Vehicle load
• Electrical load from vehicle accessories
• Traffic and road conditions
NISSAN recommends the following driv-
ing habits to help maximize vehicle
range:
Before driving:
• Follow the recommended periodic
maintenance.
• Keep tires inflated to the correct pressure.
• Keep wheels in correct alignment.
• Pre-heat or pre-cool the interior cabin while the vehicle is charging.
• Remove unnecessary cargo from the vehicle.
While driving:
• Drive in ECO mode. – The ECO mode helps reduce powerconsumption by reducing acceleration
when compared to the same accelera-
tor pedal position in the D (Drive) posi-
tion (normal mode).

SYSTEM MAINTENANCE
The sonar sensorsO1are located on the
rear bumper. Always keep the area near
the sonar sensors clean.
The sonar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.
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.

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

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,

• 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:

REAR WINDOW WIPER BLADE
It is recommended that you visit a NISSAN
certified LEAF dealer if checking or replace-
ment is required.If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN certified LEAF dealer
for this service.
WARNING
Do not adjust the height of the brake
pedal. Doing so could alter the effec-
tiveness of the brakes, which could re-
sult in a serious accident and personal
injury. If adjustment is required, it is
recommended that you visit a NISSAN
certified LEAF dealer for this service.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires re-
placement, it will make a high–pitched
scraping sound when the vehicle is in mo-
tion. This scraping sound will first occur
only when the brake pedal is depressed.
Af ter more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard. Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
