SYSTEM MAINTENANCE
The sensorAis located on the front of the
vehicle.
To keep the system operating properly, be
sure to observe the following:
• Always keep the sensor area of the front bumper clean.
• Do not strike or damage the areas around the sensor.
• Do not cover or attach stickers or similar objects on the front bumper near the sen-
sor area. This could cause failure or
malfunction.

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

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.
Starting and driving5-149

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.
Starting and driving5-151

Push the switch on to warn other drivers
when you must stop or park under emer-
gency conditions. All turn signal lights will
flash.
WARNING
• If stopping for an emergency, be sure to move the vehicle well off the
road.
• Do not use the hazard warning flashers while moving on the high-
way unless unusual circumstances
force you to drive so slowly that your
vehicle might become a hazard to
other traffic.
• Turn signals do not work when the hazard warning flasher lights are on.
The flasher can be actuated with the
power switch in any position.
Some jurisdictions may prohibit the use
of the hazard warning flasher switch
while driving. In the event of a roadside emergency,
Roadside Assistance Service is available to
you. For additional information, please refer
to your Warranty Information Booklet (U.S.)
or Warranty & Roadside Assistance Infor-
mation Booklet (Canada) for details.
HAZARD WARNING FLASHER SWITCH
ROADSIDE ASSISTANCE PROGRAM
6-2In case of emergency

To shut off the EV system in an emergency
situation while driving, perform the follow-
ing procedure.
• Rapidly push the power switch three con-secutive times in less than 1.5 seconds, or
• Push and hold the power switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires. When the low
tire pressure warning light is lit, and the “Tire
Pressure Low — Add Air” warning appears
on the vehicle information display, one or
more of your tires is significantly under-
inflated. If the vehicle is being driven with
low tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light. This system will activate only
when the vehicle is driven at speeds above
16 mph (25 km/h). For additional informa-
tion, refer to “Warning lights, indicator lights
and audible reminders” in the “Instruments
and controls” section and “Tire Pressure
Monitoring System (TPMS)” in the “Starting
and driving” section of this manual.
WARNING
• Radio waves could adversely affect electric medical equipment. Those
who use a pacemaker should con-
tact the electric medical equipment
manufacturer for the possible influ-
ences before use. • If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with underinflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
af ter adjusting the tire pressure, a
tire may be flat or the TPMS may be
malfunctioning. If you have a flat
tire, repair it as soon as possible. If
no tire is flat and all tires are properly
inflated, have the vehicle checked. It
is recommended that you visit a cer-
tified LEAF dealer for this service.

In case of emergency6-3

•When replacing a wheel without the
TPMS such as the spare tire, TPMS will
not function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain
on af ter 1 minute. Have your tires re-
placed and/or TPMS system reset as
soon as possible. It is recommended
that you visit a NISSAN certified LEAF
dealer for these services.
•Replacing tires with those not origi-
nally specified by NISSAN could affect
the proper operation of the TPMS.
• The Genuine NISSAN Emergency TireRepair Sealant or equivalent can be
used for temporarily repairing a tire.
Do not inject any other tire liquid or
aerosol tire sealant into the tires, as
this may cause a malfunction of tire
pressure sensors.
• NISSAN recommends using only Genuine NISSAN Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure. It is recom-
mended that you visit a NISSAN cer-
tified LEAF dealer as soon as pos-
sible af ter using tire repair sealant
(for models equipped with the emer-
gency tire puncture repair kit).
REPAIRING FLAT TIRE
WARNING
• Af ter using Genuine NISSAN Emer-
gency Tire Sealant to repair a minor
tire puncture, do not drive the ve-
hicle at speeds faster than 50 mph
(80 km/h).
• Immediately af ter using the Genu-
ine NISSAN Emergency Tire Sealant
to repair a minor tire puncture, it is
recommended that you visit a
NISSAN certified LEAF dealer. The
Genuine NISSAN Emergency Tire
Sealant cannot permanently seal a
punctured tire. Continuing opera-
tion of the vehicle without a perma-
nent tire repair can lead to a crash.
• If you used the Genuine NISSAN
Emergency Tire Sealant to repair a
minor tire puncture, it is recom-
mended that you visit a NISSAN cer-
tified LEAF dealer to replace the
TPMS sensor in addition to repairing
or replacing the tire. •
NISSAN recommends using only
Genuine NISSAN Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure.
This vehicle does not have a spare tire. The
emergency tire puncture repair kit (Genu-
ine NISSAN Emergency Tire Sealant) is sup-
plied with the vehicle instead of a spare tire.
It can be used to temporarily repair minor
tire punctures.
If possible, have the vehicle towed to a fa-
cility that can repair or replace the flat tire.
Using the emergency tire puncture repair
kit may cause a malfunction of the tire
pressure sensor and cause the low tire
pressure warning light to illuminate.
