emergency warning indicator (red), provid-
ing an audible warning, and then automati-
cally applies harder braking.
If a risk of a forward impact with a pedes-
trian is detected, the AEB with Pedestrian
Detection system will provide a warning to
the driver by flashing the AEB with Pedes-
trian Detection emergency warning indica-
tor (red), provides an audible alert and the
system will apply partial braking. If the
driver applies the brakes quickly and force-
fully but the AEB with Pedestrian Detection
system detects that there is still the possi-
bility of a forward impact with a pedestrian,
the system will automatically increase the
braking force. If the risk of collision be-
comes imminent and the driver does not
take action, the AEB with Pedestrian Detec-
tion system automatically applies harder
braking.
NOTE:
The vehicle’s brake lights come on when
any braking is performed by the AEB
with Pedestrian Detection system.Depending on vehicle speed and distance
to the vehicle or pedestrian ahead, as well
as driving and roadway conditions, the sys-
tem may help the driver avoid a forward
collision or may help mitigate the conse-
quences if a collision should be unavoid-
able. If the driver is handling the steering
wheel, accelerating or braking, the AEB with
Pedestrian Detection system will function
later or will not function.
The automatic braking will cease under the
following conditions:
• When the steering wheel is turned to
avoid a collision.
• When the accelerator pedal is depressed.
• When there is no longer a vehicle or a pedestrian detected ahead.
If the AEB with Pedestrian Detection sys-
tem has stopped the vehicle, the vehicle
will remain at a standstill for approximately
2 seconds before the brakes are released.

Starting and driving5-141

• 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.

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

Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, the braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal
to heat up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
have dried.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking perfor-
mance.
This procedure is described in the Genuine
NISSAN Service Manual, and it can be per-
formed by a certified repair facility. It is rec-
ommended that you visit a NISSAN certi-
fied LEAF dealer.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but it cannot prevent accidents re-
sulting from careless or dangerous
driving techniques. It can help main-
tain vehicle control during braking
on slippery surfaces. Remember
that stopping distances on slippery
surfaces will be longer than on nor-
mal surfaces even with ABS. Stop-
ping distances may also be longer
on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance
from the vehicle in front of you. Ulti-
mately, the driver is responsible for
safety.
• Tire type and condition may also af- fect braking effectiveness.
– When replacing tires, install thespecified size of tires on all four
wheels.
– For additional information, refer to “Wheels and tires” in the “Main-
tenance and do-it-yourself ” sec-
tion of this manual. The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
5-148Starting and driving

If the “Chassis Control System Error: See
Owner’s Manual” warning message ap-
pears in the vehicle information display, it
may indicate that the I-TC is not function-
ing properly. Have the system checked as
soon as possible. It is recommended that
you visit a NISSAN certified LEAF dealer for
this service.
WARNING
The I-TC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively.
When the I-TC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
I-TC is operating properly.
Even if the I-TC is turned off, some functions
will remain on to assist the driver (for ex-
ample, avoidance scenes).
ACTIVE RIDE CONTROL (ARC)
This system senses upper body motion
(based on wheel speed information) and
controls motor torque. This will enhance
ride comfort in effort to restrain uncom-
fortable upper body movement when
passing over undulated road surfaces. This
system comes into effect above 25 mph
(40 km/h).
When the VDC OFF switch is used to turn off
the VDC system, the Active Ride Control is
also turned off.WARNING
• Never rely solely on the hill start as- sist system to prevent the vehicle
from moving backward on a hill. Al-
ways drive carefully and attentively.
Depress the brake pedal when the
vehicle is stopped on a steep hill. Be
especially careful when stopped on
a hill on frozen or muddy roads. Fail-
ure to prevent the vehicle from roll-
ing backwards may result in a loss of
control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de- signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and
may result in a collision or serious
personal injury.
• The hill start assist may not prevent the vehicle from rolling backwards
on a hill under all load or road condi-
tions. Always be prepared to de-
press the brake pedal to prevent the
vehicle from rolling backwards. Fail-
ure to do so may result in a collision
or serious personal injury.
