2019 NISSAN LEAF wheel

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.

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

Self-test feature
The Anti-lock Braking System (ABS) in-
cludes 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 po-
sition 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 mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates 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 ve-
hicle checked. It is recommended that you
visit a NISSAN certified LEAF dealer for this
service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates 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 applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
drivers responsibility to stay alert,
drive safely and be in control of the
vehicle at all times.

The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions.
• Controls brake pressure to reduce wheelslip on one slipping drive wheel so power
is transferred to a drive wheel on the same
axle that is not slipping.
• Controls brake pressure and traction mo- tor output to reduce drive wheel slip
based on vehicle speed (traction control
function).
• Controls brake pressure at individual wheels and traction motor output to help
the driver maintain control of the vehicle
in the following conditions:
• Understeer (vehicle tends to not follow the steered path despite increased steering
input).
• Oversteer (vehicle tends to spin due to certain road or driving conditions).
The VDC system can help the driver main-
tain control of the vehicle, but it cannot
prevent loss of vehicle control in all driving
situations. When the VDC system operates, the
indicator light in the instrument panel
flashes. When the indicator light flashes,
note the following items:
• The road may be slippery or the system
may determine some action is required to
help keep the vehicle on the steered path.
• You may feel a pulsation in the brake pedal and hear a noise or vibration from under
the hood. This is normal and indicates
that the VDC system is working properly.
• Adjust your speed and driving according to the road conditions.
For additional information, refer to “Slip in-
dicator light” and “Vehicle Dynamic Control
(VDC) OFF indicator light” in the “Instru-
ments and controls” section of this manual.
If a malfunction occurs in the system, the
indicator light illuminates in the ve-
hicle information display. The VDC system
automatically turns off when this indicator
light is lit. The vehicle information display is used to
turn off the VDC system. The VDC OFF indi-
cator light
illuminates to indicate that
the VDC system is off. When the vehicle
information display is used to turn off the
system, the VDC system still operates to
prevent one drive wheel from slipping by
transferring power to a non-slipping wheel.
The
indicator light flashes if this oc-
curs. All other VDC functions are off and the
indicator light will not flash. The VDC
system is automatically reset to on when
the power switch is placed in the OFF posi-
tion then back to the ON position. For addi-
tional information, refer to “Vehicle infor-
mation display” in the “Instruments and
controls” section of this manual.
The computer has a built-in diagnostic fea-
ture that tests the system each time you
start the EV and move the vehicle forward
or in reverse at a slow speed. When the
self-test occurs, you may hear a “clunk”
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indica-
tion of a malfunction.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-150Starting and driving

WARNING
• The VDC system is designed to help the driver maintain stability but
does not prevent accidents due to
abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful
when driving and cornering on slip-
pery surfaces and always drive care-
fully.
• Do not modif y the vehicle’s suspen- sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars, bushings and wheels
are not NISSAN recommended for
your vehicle or are extremely dete-
riorated the VDC system may not op-
erate properly. This could adversely
affect vehicle handling perfor-
mance, and the
indicator light
may flash or theindicator
light may illuminate. • If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC sys-
tem may not operate properly and
the
indicator light may illumi-
nate.
• If traction motor control related parts are not NISSAN recommended
or are extremely deteriorated, the
indicator light may illuminate.
• When driving on extremely inclined surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the
indicator
light may illuminate. Do not drive on
these types of roads.
• When driving on an unstable surface such as a turntable, ferry, elevator or
ramp, the
indicator light may il-
luminate. This is not a malfunction.
Restart the EV system af ter driving
onto a stable surface.
• If wheels or tires other than the NISSAN recommended ones are
used, the VDC system may not oper-
ate properly and the
indicator
light may illuminate. • The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.

The chassis control is an electric control
module that includes the following func-
tions:
• Intelligent Trace Control
• Active Ride Control
INTELLIGENT TRACE CONTROL
(I-TC)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to aid tracing at corners
and help smooth vehicle response.
The I-TC can be set to on (enabled) or off
(disabled) through the vehicle information
display “Settings” page. For additional infor-
mation, refer to “Vehicle information dis-
play” in the “Instruments and controls” sec-
tion of this manual.When the Vehicle Dynamic Control (VDC)
OFF switch is used to turn off the VDC sys-
tem, the I-TC is also turned off.
When the I-TC is operated and the “Chassis
Control” mode is selected in the vehicle in-
formation display, the I-TC graphics are
shown in the vehicle information display.
For additional information, refer to “Vehicle
information display” in the “Instruments
and controls” section of this manual.
CHASSIS CONTROL
5-152Starting 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.

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.
