brakes NISSAN LEAF 2015 1.G Owners Manual

•Less deceleration is provided by the re-
generative brake system when the Li-ion
battery is fully charged. Regenerative
brake is automatically reduced when the
Li-ion battery is fully charged to prevent
the Li-ion battery from becoming over-
charged. Regenerating brake is also auto-
matically reduced when the battery tem-
perature is high/low (indicated by the red/
blue zones on the Li-ion battery
temperature gauge) to prevent Li-ion bat-
tery 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
operation.NOISE AND VIBRATION
You might experience the following noise or vi-
bration as a normal characteristic of this vehicle.
• Traction motor noise from motor compartment.
• Water pump and radiator fan noise while charg-
ing.
• Compressor and radiator fan noise when the Climate Ctrl. Timer or remote climate control
(models with navigation system) is used.
• Relay operation noise and vibration at start-up and shut-down of the EV (Electric Vehicle) sys-
tem (power switch placed in the ON and OFF
position) .
• Approaching Vehicle Sound for Pedestrians (VSP) . This section provides a brief explanation for the
most important LEAF functions. Refer to the spe-
cific sections of this manual for detailed explana-
tions of the vehicle features and operation.
CHARGING THE LI-ION BATTERY
WARNING
The EV (Electric Vehicle) system uses a
high voltage current. Failure to follow the
proper handling instructions may cause
serious injury or death. Be sure to read
the “Charge” section and follow the pro-
cedures and guidelines described.
LIFE WITH AN EV (SCENE GUIDE)
EV-10EV Overview

• Release the accelerator pedal to slow downand do not apply the brakes when traffic and
road conditions allow. – This vehicle is equipped with a regenerative brake system. The primary purpose of re-
generative 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)
position, when the accelerator is released,
the regenerative brake system provides
some deceleration and some power to the
Li-ion battery.
LI-ION BATTERY LIFE
The Li-ion battery’s ability to hold a charge, like all
batteries, decreases with battery age and usage
which results in decreased vehicle range when
compared to the vehicle range when the vehicle
was new. This is normal and expected, and does
not indicate a malfunction of the vehicle or Li-ion
battery. The Li-ion battery’s ability to hold a charge can be
affected by how you drive the vehicle, store the
vehicle, how you charge the Li-ion battery and
Li-ion battery temperature during vehicle opera-
tion and charging.
To maximize the battery’s useful life, use the fol-
lowing driving and charging habits where pos-
sible:
• Avoid exposing a vehicle to extreme ambient
temperatures for extended periods.
• Avoid storing a vehicle in temperatures below −13°F (−25°C) for over 7 days.
• Avoid leaving your vehicle for over 14 days where the Li-ion battery available charge gauge
reaches a zero or near zero (state of charge) .
• Allow the vehicle and Li-ion battery to cool down after use before charging.
• Park/store your vehicle in cool locations out of direct sunlight and away from heat sources.
• Avoid sustained high battery temperatures (caused, for example, by exposure to very high
ambient temperatures or extending highway
driving with multiple quick charges) . • Use the normal charging or trickle charging
methods to charge the Li-ion battery and mini-
mize the use of public Fast Charge or Quick
Charger.
• Avoid repetitive charging of the Li-ion battery with high battery state of charge.
• Moderate driving.
• Use of ECO mode.
• If the vehicle will not be used for an extended period of time, charge the Li-ion battery once
every 3 months. Do not operate the charging
timer repeatedly while the charge connector is
connected to the vehicle after the Li-ion battery
charging is completed. Doing so may discharge
the 12-volt battery.
The power of the Li-ion battery can be
checked on the Li-ion battery available charge
gauge. See “Li-ion battery available charge
gauge” in the “Instruments and controls” for
details.

This light flashes when the turn signal switch
lever or hazard switch is turned on.
Vehicle Dynamic Control
(VDC) off indicator light
This light illuminates when the Vehicle Dynamic
Control (VDC) switch is pushed to OFF. This
indicates that the VDC system is not operating.
See “Vehicle Dynamic Control (VDC) system” in
the “Starting and driving” section.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear warnings.
When a brake pad requires replacement, it will
make a high pitched scraping sound when the
vehicle is in motion. This scraping sound will first
occur only when the brake pedal is depressed.
After 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 warning sound is heard.
Electric shift control system reminder
chime
If an improper shift operation is performed, for
safety reasons a chime will sound and at the
same time, depending on the conditions, the
operation will be cancelled or the shift position
will switch to the N position.
For more details, see “Driving vehicle” in the
“Starting and driving” section.
Key reminder chime
A chime will sound if the driver’s side door is
opened while the power switch is pushed to the
ON or ACC position.Make sure that the power switch is pushed to the
OFF position, and take the Intelligent Key with
you when leaving the vehicle.
Light reminder chime
The light reminder chime will sound when the
driver side door is opened with the light switch in
the
orposition, and the power
switch in the ACC, OFF or LOCK position.
Turn the light switch off when you leave the
vehicle.
Parking brake reminder chime
A chime sounds if the parking brake is set and the
vehicle is driven. The chime will stop if the parking
brake is released or the vehicle speed returns to
zero.
Power switch reminder chime (if so
equipped)
The power switch reminder chime will sound
when the driver’s door is opened while the power
switch is in the ON or READY position. Push the
power switch to the OFF position.
Instruments and controls2-21

– There is a malfunction in the horn or hazardindicators.
– If the Easy Fill Tire Alert does not operate due to TPMS interference, move the vehicle
about 3 ft (1 m) backward or forward and try
again.
If the Easy Fill Tire Alert is not working, use a tire
pressure gauge.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle. As with
any vehicle, a loss of control could result in
a collision with other vehicles or objects, or
cause the vehicle to rollover, particularly if
the loss of control causes the vehicle to
slide sideways. Be attentive at all times, and avoid driving when tired. Never drive when under
the influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Seat belts” in the “Safety —
Seats seat belts and supplemental restraint sys-
tem” section of this manual, and also instruct your
passengers to do so.
Seat belts help reduce the risk of injury in colli-
sions and rollovers.
In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If this
occurs, maintain control of the vehicle by follow-
ing the procedure below. Please note that this
procedure is only a general guide. The vehicle
must be driven as appropriate based on the con-
ditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a straight course. 4. When appropriate, slowly release the accel-
erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the vehicle speed is
reduced. Do not attempt to drive the vehicle
back onto the road surface until vehicle speed
is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return to the
road surface. When all tires are on the road
surface, steer the vehicle to stay in the appro-
priate driving lane.
• If you decide that it is not safe to return the vehicle to the road surface based on vehicle,
road or traffic conditions, gradually slow the
vehicle to a stop in a safe place off the road.RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can occur
if the tire is punctured or is damaged due to
hitting a curb or pothole. Rapid air pressure loss
can also be caused by driving on under-inflated
tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds.
Starting and driving5-5

Help prevent rapid air pressure loss by maintain-
ing the correct air pressure and visually inspect
the tires for wear and damage. See “Wheels and
tires” in the “Maintenance and do-it-yourself”
section of this manual.
If a tire rapidly loses air pressure or “blows-out”
while driving maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The ve-
hicle must be driven as appropriate based on the
conditions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
• The vehicle generally moves or pulls in the direction of the flat tire.
• Do not rapidly apply the brakes.
• Do not rapidly release the accelerator pedal.
• Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a straight course. 3. When appropriate, slowly release the accel-
erator pedal to gradually slow the vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from traffic if possible.
5. Lightly apply the brake pedal to gradually stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emergency service to
change the tire or see “Flat tire” in the “In case
of emergency” section of this Owner’s
Manual.DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the bloodstream
reduces coordination, delays reaction
time and impairs judgement. Driving af-
ter drinking alcohol increases the likeli-
hood of being involved in an accident
injuring yourself and others. Additionally,
if you are injured in an accident, alcohol
can increase the severity of the injury.
NISSAN is committed to safe driving. However,
you must choose not to drive under the influence of alcohol. Every year thousands of people are
injured or killed in alcohol-related accidents. Al-
though the local laws vary on what is considered
to be legally intoxicated, the fact is that alcohol
affects all people differently and most people
underestimate the effects of alcohol.
Remember, drinking and driving don’t mix! That is
true for drugs too (over-the-counter, prescrip-
tion, and illegal drugs) . Do not drive if your ability
to operate your vehicle is impaired by alcohol,
drugs, or some other physical condition.
5-6Starting and driving

N (Neutral):
Neither forward nor reverse gear is engaged. The
vehicle can be placed in READY to drive position
in this position.
Do not shift to the N (Neutral) position while
driving. The regenerative brake system does not
operate in the N (Neutral) position. However, the
vehicle brakes will still stop the car.
D (Drive):
Use this position for all normal forward driving.If
the vehicle is placed in the D (Drive) posi-
tion while reversing, the chime will sound
and the vehicle will switch into the N (Neu-
tral) position. B-mode:
Engages the regenerative braking system more
aggressively on downhill slopes, and helps re-
duce brake use. Activated by moving the shift
lever left and down. The shift lever will then return
to the center position.ECO mode (if so equipped):
Use ECO in order to help extend the driving
range.
In comparison to the D (Drive) position, ECO
consumes less power for the traction motor and
enables the range of the vehicle to be extended.
ECO can be selected from the D (Drive) or
B-mode position.
5-14Starting and driving

– The ECO position helps reduce power con-sumption by reducing acceleration when
compared to the same accelerator pedal
position in the D (Drive ) position.
• Drive at a constant speed. Maintain cruising speeds with a constant accelerator positions or
by using cruise control when appropriate.
• Accelerate slowly and smoothly. Gently press and release the accelerator pedal for accelera-
tion 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 heat- ing or cooling to help reduce power
consumption.
• Use the air conditioner/heater and close win- dows to reduce drag when cruising at 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 regenerative brake system. The primary purpose of re-
generative 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)
position, when the accelerator pedal is re-
leased, the regenerative brake system pro-
vides some deceleration and some power to
the Li-ion battery.
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 un-
attended.
• Do not leave children unattended in- side the vehicle. They could unknow-
ingly activate switches or controls. Un-
attended children could become
involved in serious accidents.
• Safe parking procedures require that both the parking brake be applied and
the vehicle placed in the park position.
Failure to do so could cause the ve-
hicle to move unexpectedly or roll
away and result in an accident.
PARKING/PARKING ON HILLS
5-18Starting and driving

You may hear a noise when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the power steering warning light
illumi-
nates while the READY to drive indicator light is
ON, it may indicate the power steering system is
not functioning properly and may need servicing.
Have the power steering system checked by a
NISSAN certified LEAF dealer. (See “Power
steering warning light” in the “Instruments and
controls” section.)
The power assist for steering stops operating
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 sys-
tems:
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 hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Regenerative brake system
The primary purpose of regenerative brake sys-
tem is to provide some power to help recharge
the Li-ion battery and extend driving range. A
secondary benefit is “engine braking” that oper-
ates based on battery conditions.
In the D (Drive) range, when the accelerator is
released, the regenerative brake system provides
some deceleration and generates power for the
Li-ion battery. Power is also generated when the
brake pedal is applied.
When you put the shift lever in the ECO position
and take your foot off the accelerator pedal, more regenerative brake is applied than in the D (Drive)
position. However, during high-speed driving you
may feel that regenerative brake provides less
deceleration than the engine braking in an ordi-
nary vehicle. This is normal.
Less deceleration is provided by the regenerative
brake system when the Li-ion battery is fully
charged. Regenerative brake is automatically re-
duced when the Li-ion battery is fully charged to
prevent the Li-ion battery from becoming over-
charged. Regenerative brake is also automati-
cally reduced when the battery temperature is
high/low (indicated by the red/blue zones on the
battery temperature gauge) to prevent Li-ion bat-
tery damage.
The brake pedal should be used to slow or stop
the vehicle depending on traffic or road condi-
tions. The vehicle brakes are not affected by
regenerative brake system operation.
NOTE:
•
When applying the regenerative brakes,
you may hear a sound coming from the
regenerative brake system. This is a nor-
mal operating characteristic of an EV
(Electric vehicle) .
BRAKE SYSTEM
5-20Starting and driving

•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 pres-
sure on the brake pedal will be required to
stop the vehicle, and the stopping dis-
tance will be longer.
• When depressing the brake pedal, the
braking pedal feel will not be smooth or
may change when the cooperative regen-
erative brake system activates. However,
the electronically controlled brake system
is operating normally and this does not
indicate a malfunction.
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the brakes,
wearing out 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 se-
lect ECO position before going down a slope or
long grade. Overheated brakes may reduce brak-
ing performance and could result in loss of ve-
hicle control.
WARNING
• While driving on a slippery surface, be careful when braking or accelerating.
Abrupt braking or accelerating could
cause the wheels to skid, which could
result in an accident.
• If the brake pedal is depressed with the EV (Electric Vehicle) system OFF,
you may feel an increased brake pedal
effort and a decreased pedal stroke. If
the BRAKE warning light does not illu-
minate and the brake pedal feels like it
has returned to its normal state after
the EV system is started, this indicates
that there is no malfunction and the
vehicle can be operated normally.
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
holding effect of the parking brake is weakened
or whenever the parking brake shoes are re-
placed, in order to maintain optimum braking
performance.
This procedure is described in the vehicle Ser-
vice Manual, and it can be performed by a
NISSAN certified LEAF dealer.
Starting and driving5-21

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
• The Anti-lock Braking System (ABS) is a sophisticated device, but it cannot
prevent accidents resulting from care-
less or dangerous driving techniques.
It can help maintain vehicle control
during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than
on normal surfaces even with ABS.
Stopping 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. Ultimately,
the driver is responsible for safety.
• Tire type and condition may also affect braking effectiveness.
– When replacing tires, install thespecified size of tires on all four
wheels.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard brak-
ing or when braking on slippery surfaces. The sys-
tem detects the rotation speed at each wheel and
varies the brake fluid pressure to prevent 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. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate 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.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that tests
the system each time you push the power switch in
the READY to drive position and move the vehicle at a low speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise and/or feel
a pulsation in the brake pedal. This is normal and
does not indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off and
illuminates the ABS warning light on the instrument
panel. The brake system then operates normally, but
without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN certified LEAF dealer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h) . The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
