change to ACC.
NOTE:
• When the power switch is pushed to the
ACC or ON position or READY to drive
mode by the above procedure, the EV
system operation for discharged Intelli-
gent Key system indicator appears on
the vehicle information display even if
the Intelligent Key is inside the vehicle.
This is not a malfunction. To stop the
warning indicator from blinking, touch
the power switch with the Intelligent
Key again. •
If the Intelligent Key battery discharge
indicator appears on the vehicle infor-
mation display, replace the battery as
soon as possible. For additional infor-
mation, refer to “NISSAN Intelligent Key®
battery replacement” in the “Mainte-
nance and do-it-yourself ” section of
this manual.
NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the power switch to be placed
in the READY to drive position without the
use of the registered key.
If the power switch fails to place the vehicle
into the READY to drive position using the
registered key, it may be due to interfer-
ence caused by another registered key, an
automated toll road device or automated
payment device on the key ring. Restart the
EV system using the following procedure:
1. Leave the power switch in the ON posi-
tion for approximately 5 seconds.
2. Place the power switch in the OFF posi- tion and wait approximately 10 seconds. 3. Repeat steps 1 and 2 again.
4. Place the power switch in the READY to
drive position while holding the device
(which may have caused the interfer-
ence) separate from the registered key.
If this procedure allows the power
switch to be placed in the READY to drive
mode, NISSAN recommends placing the
registered key on a separate key ring to
avoid interference from other devices.

SWITCH TYPE (MODELS WITH
ELECTRONIC PARKING BRAKE
SYSTEM)
The electronic parking brake can be ap-
plied or released automatically or by oper-
ating the electronic parking brake switch.
Automatic operation
The electronic parking brake is automati-
cally released as soon as the vehicle starts
and the accelerator pedal is depressed.
In order for the electronic parking brake to
disable when the driver pushes the accelera-
tor, the driver’s seat belt must be fastened.
WARNING
• The electronic parking brake will not be automatically applied when the
EV system is stopped without using
the power switch (for example, by EV
system stalling).
• Before leaving the vehicle, move the shif t lever to the P (Park) position
and check that the electronic park-
ing brake indicator light (
or
PARK) is illuminated to confirm that
the electronic parking brake is ap-
plied. The electronic parking brake
indicator light (
or PARK) will re-
main on for a period of time af ter the
driver’s door is locked.
CAUTION
When parking in an area where the
outside temperature is below 32°F
(0°C), the parking brake, if applied, may
freeze in place and may be difficult to
release.
For safe parking, it is recommended
that you place the shif t lever in the P
(Park) position and securely block the
wheels.
NOTE:
• If a malfunction occurs in the electronic
parking brake system (for example,
due to battery discharge), it is recom-
mended that you visit a NISSAN certi-
fied LEAF dealer.
• If the shif t lever is moved to the P (Park)
position when the brake force is main-
tained by the automatic brake hold
function, the electronic parking brake
will apply automatically.
• If the driver’s seat belt is unfastened
when the brake force is maintained by
the automatic brake hold function, the
electronic parking brake will apply au-
tomatically.
• When the ICC system (if so equipped) is
canceled under the following condi-
tions at a standstill, the electronic park-
ing brake is automatically activated:
– Any door is open.
– The driver’s seat belt is not fastened.
– Your vehicle has been stopped by the ICC system for approximately
3 minutes or longer.
– The shif t lever is not in the D (Drive) position or B mode.
5-20Starting and driving

• Drive at a constant speed. Maintain cruis-ing speeds with a constant accelerator
position or by using cruise control when
appropriate.
• Accelerate slowly and smoothly. Gently press and release the accelerator pedal
for acceleration and deceleration.
• Drive at moderate speeds on the highway.
• Avoid frequent stopping and braking. Maintain a safe distance behind other
vehicles.
• Turn off the air conditioner/heater when it is not necessary.
• Select a moderate temperature setting for heating or cooling to help reduce
power consumption.
• Use the air conditioner/heater and close windows to reduce drag when cruising at
a highway speed. • Release the accelerator pedal to slow
down and do not apply the brakes when
traffic and road conditions allow. – This vehicle is equipped with a regen-erative brake system. The primary pur-
pose of the regenerative brake system
is to provide some power to recharge
the Li-ion battery and extend driving
range. A secondary benefit is “engine
braking” that operates based on Li-ion
battery conditions. In the D (Drive) posi-
tion, when the accelerator pedal is re-
leased, the regenerative brake system
provides some deceleration and some
power to the Li-ion battery. The ECO Drive Report appears for approxi-
mately 30 seconds af ter placing the power
switch in the OFF position, driving the ve-
hicle for more than 0.3 miles (500 m), and
pressing the
button on the steering
wheel.

4. Regenerated energy (mileage)
Displays the amount of regenerated en-
ergy stored in the Li-ion battery in one
trip in terms of distance If the vehicle has been driven mostly on
downhill roads, more energy is regener-
ated. This may cause the regenerated en-
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, refer to “Ve-
hicle information display” in the “Instru-
ments and controls” section of this manual.
WARNING
• Do not stop or park the vehicle over flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
• Never leave the vehicle in the READY to drive mode while the vehicle is
unattended.
• Safe parking procedures require that both the parking brake be ap-
plied and the vehicle placed in the
park position. Failure to do so could
cause the vehicle to move unexpect-
edly or roll away and result in an ac-
cident.
• Do not leave children unattended in- side the vehicle. They could un-
knowingly activate switches or con-
trols or make the vehicle move.
Unattended children could become
involved in serious accidents.
PARKING/PARKING ON HILLS
5-144Starting and driving

WARNING
• If the READY to drive indicator light is off while driving, the power assist for
the steering will not work. Steering
will be harder to operate.
• When the power steering warning light illuminates while the READY to
drive indicator light is on, the power
assist for the steering will cease op-
eration. You will still have control of
the vehicle but the steering will be
harder to operate.
The power steering system is designed to
provide power assistance while driving to
operate the steering wheel with less effort.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and help protect it from
getting damaged. When the power assis-
tance is reduced, steering wheel operation
will become harder. When the temperature
of the power steering system goes down,
the power assistance level will return to normal. Avoid repeating such steering
wheel operations that could cause the
power steering system to overheat.
You may hear a noise when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light
illuminates while the READY to drive indica-
tor light is on, it may indicate the power
steering system is not functioning properly
and may need servicing. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service. For additional
information, refer to “Power steering warn-
ing light” in the “Instruments and controls”
section of this manual.
The power assist for steering stops operat-
ing when both the power steering warning
light and READY to drive indicator light are
illuminated. You will still have control of the
vehicle. However, greater steering effort is
needed, especially in sharp turns and at
low speeds.
BRAKE PRECAUTIONS
This vehicle is equipped with two braking
systems:
1. Hydraulic brake system
2. Regenerative brake system
Hydraulic brake system
The hydraulic brake system is similar to the
brakes used on conventional vehicles.
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Regenerative brake system
The primary purpose of the regenerative
brake system is to provide some power to
help recharge the Li-ion battery and ex-
tend driving range. A secondary benefit is
“engine braking” that operates based on
battery conditions.
In the D (Drive) range, when the accelerator
is released, the regenerative brake system
provides some deceleration and gener-
ates power for the Li-ion battery. Power is
also generated when the brake pedal is
applied.
POWER STEERING SYSTEM
BRAKE SYSTEM
5-146Starting and driving

When you put the shif t lever in the B mode
and take your foot off the accelerator
pedal, more regenerative brake is applied
than in the D (Drive) position. However, dur-
ing high-speed driving you may feel that
regenerative brake provides less decelera-
tion than the engine braking in an ordinary
vehicle. This is normal.
Less deceleration is provided by the regen-
erative brake system when the Li-ion bat-
tery is fully charged. Regenerative brake is
automatically reduced when the Li-ion
battery is fully charged to prevent the Li-ion
battery from becoming overcharged. Re-
generative brake is also automatically re-
duced when the battery temperature is
high/low (indicated by the red/blue zones
on the battery temperature gauge) to pre-
vent Li-ion battery 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 op-
eration.NOTE:
•When applying the regenerative brakes,
you may hear a sound coming from the
regenerative brake system. This is a
normal operating characteristic of an
EV.
• If the power switch position is in a posi-
tion other than ON or READY to drive,
you can stop the vehicle by depressing
the brake pedal. However, greater foot
pressure on the brake pedal will be re-
quired to stop the vehicle, and the stop-
ping distance will be longer.
• When depressing the brake pedal, the
brake pedal feel will not be smooth or
may change when the cooperative re-
generative brake system activates.
However, the electronically controlled
brake system is operating normally and
this does not indicate a malfunction.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating of
the brakes, wearing out of the brake pads
and shoes faster, and will reduce driving
range. To help reduce brake wear, and to prevent
the brakes from overheating, reduce speed
and select B mode before going down a
slope or long grade. Overheated brakes
may reduce braking performance and
could result in loss of vehicle control.
WARNING
• While driving on a slippery surface, be careful when braking or acceler-
ating. Abrupt braking or accelerat-
ing could cause the wheels to skid,
which could result in an accident.
• If the brake pedal is depressed with the EV system OFF, you may feel an
increased brake pedal effort and a
decreased pedal stroke. If the BRAKE
warning light does not illuminate
and the brake pedal feels like it has
returned to its normal state af ter the
EV system is started, this indicates
that there is no malfunction and the
vehicle can be operated normally.
Starting and driving5-147

The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the brake
pedal and apply the accelerator when the
vehicle is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
• The shif t lever is placed in the D (Drive), Bmode, or R (Reverse) position.
• The vehicle is stopped completely on a hill by applying the brake.
The maximum holding time is 2 seconds.
Af ter 2 seconds the vehicle will begin to roll
back and hill start assist will stop operating
completely.
Hill start assist will not operate when the
shif t lever is placed in the N (Neutral) or P
(Park) position or on a flat and level road.
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 posi-
tion 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. Vehicle driving range is re-
duced if the Li-ion battery warmer (if so
equipped) operates (Li-ion battery tem-
perature 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 bat-
tery 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 reduced
when using the Climate Ctrl. Timer or
Remote Climate Control while the Li-ion
battery warmer (if so equipped) oper-
ates (for models with 40 kWh battery
model). Set only the charging timer [End
Time] when charging in cold weather.
The vehicle automatically determines
when to start charging to fully charge
the Li-ion battery, even if the Li-ion bat-
tery warmer operates. Charging ends
before the set end time if the Li-ion bat-
tery is fully charged.
COLD WEATHER DRIVING
5-154Starting and driving

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.
