brakes NISSAN LEAF 2017 1.G Owners Manual

•Less deceleration is provided by the re-
generative brake system when the Li-ion
battery is fully charged. The regenerative
brake is automatically reduced when the
Li-ion battery is fully charged to prevent
the Li-ion battery from becoming over-
charged. The regenerative brake is also
automatically reduced when the battery
temperature is high/low (indicated by the
red/blue zones on the Li-ion battery tem-
perature gauge) to prevent 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 the 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 the motor compartment.
• Water pump and radiator fan noise while charging.
• 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 system (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. For additional
information, refer to the specific sections of this
manual for detailed explanations of the vehicle
features and operation.
CHARGING THE LI-ION BATTERY
WARNING
The EV system uses a high voltage cur-
rent. Failure to follow the proper han-
dling instructions may cause serious in-
jury or death. Be sure to read the
“Charging” section and follow the proce-
dures 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 the
regenerative brake system is to provide
some power to recharge the Li-ion battery
and extend driving range. A secondary ben-
efit 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 more than 7 days.
• Avoid leaving your vehicle for more than 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 (if so
equipped)) . • 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.
• Do not operate the charging timer repeatedly while the charge connector is connected to the
vehicle after the Li-ion battery charging is com-
pleted. 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. For
additional information, refer to “Li-ion battery
available charge gauge” in the “Instruments and
controls” section of this manual.

pressure reaches the designated pressure, the
horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds after starting to in-
flate the tire, it indicates that the Easy-Fill Tire
Alert is not operating.
• The TPMS will not activate the Easy-Fill Tire Alert under the following conditions: – If there is interference from an external de- vice or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the tire, such as those
using a power socket.
– If electrical equipment is being used in or near the vehicle.
– There is a malfunction in the TPMS system.
– There is a malfunction in the horn or hazard indicators.
– 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 “Seat belts” in the “Safety — Seats,
seat belts and supplemental restraint system”
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.
Starting and driving5-5

6. When it is safe to do so, gradually turn thesteering 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.
Help prevent rapid air pressure loss by maintain-
ing the correct air pressure and visually inspect-
ing the tires for wear and damage. For additional
information, refer to “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 con- tact a roadside emergency service to change
the tire. For additional information, refer to
“Flat tire” in the “In case of emergency” sec-
tion of this 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

P (Park):
Use this shift position when the vehicle is parked
or when placing the vehicle in the READY to drive
position. Make sure that the vehicle is completely
stopped.In order to switch to the P (Park)
position, push the P (Park) position switch
as shown in the illustration above once the
vehicle has come to a complete stop. If the
P (Park) position switch is pushed while the
vehicle is in motion, a chime sounds and
the current shift position is maintained. Af-
ter switching to the P (Park) position, apply the
parking brake. When parking on a hill, apply the
parking brake first while keeping the foot brake
pedal depressed then push the P (Park) position
switch and place the vehicle in the P (Park) position. For additional information, refer to
“Parking brake” in this section.
NOTE:
•
While the vehicle is stationary, if the shift
position is placed in any position other
than the P (Park) position when the power
switch is set to OFF, it will automatically
switch to the P (Park) position.
• If the P (Park) position switch is pushed
while sliding the shift lever, the shift posi-
tion will not switch to the P (Park) posi-
tion. When pushing the P (Park) position
switch be sure to first allow the shift lever
to return to its center position.
R (Reverse):
Use this position to back up. Make sure that the
vehicle is completely stopped before selecting
the R (Reverse) position. If the vehicle is
placed in the D (Drive) position while re-
versing, the chime will sound and the ve-
hicle will switch into the N (Neutral)
position. N (Neutral):
Neither forward nor reverse gear is engaged. The
vehicle can be placed in the 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.
5-14Starting and driving

• Push, then quickly release, the COAST/SETswitch. Each time you do this, the set speed will
decrease by about 1 mph or 1km/h.
To resume the preset speed, push and re-
lease the ACCEL/RES switch. The vehicle will
resume the last set cruising speed when the
vehicle speed is over 25 mph (40 km/h) . Vehicle range depends on a number of factors.
Actual vehicle range will vary depending upon:
• speed
• vehicle load
• electrical load from vehicle accessories
• traffic and road conditions
NISSAN recommends the following driving
habits to help maximize vehicle range:
Before driving:
• Follow recommended periodic maintenance.
• Keep tires inflated to 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 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 position 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 the

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 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. It is
recommended that you visit a NISSAN certified
LEAF dealer for this service. For additional infor-
mation, refer to “Power steering warning light” in
the “Instruments and controls” section of this
manual.
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 the regenerative brake
system is to provide some power to help re-
charge the Li-ion battery and extend 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 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 B 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.
BRAKE SYSTEM
Starting and driving5-21

•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
brake 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 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 se-
lect B position 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 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 system OFF, you may feel an
increased brake pedal effort and a de-
creased pedal stroke. If the BRAKE
warning light does not illuminate and
the brake pedal feels like it has re-
turned 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
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drum/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the Genuine
NISSAN Service Manual, and it can be per-
formed by a certified repair facility. It is recom-
mended that you visit a NISSAN certified LEAF
dealer.
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
5-22Starting and driving

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 additional information, refer to “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
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 slip-
pery 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 malfunc-
tion, 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. It is recommended that you visit a
NISSAN certified LEAF dealer for this service.
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.
