tire briefly to release pressure. When the pres-
sure 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 an 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 maneuvers,
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 (in-
cluding prescription or over-the-counter drugs
which may cause drowsiness) . Always wear your
seat belt as outlined in the
Seat beltsin 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

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 ON, the power assist for
the steering will cease operation. You
will still have control of the vehicle but
the steering will be harder to operate.
The power steering system is designed to pro-
vide power assistance while driving to operate
the steering wheel with less effort.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and help
protect it from getting damaged. While the power
assistance 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 re-
peating such steering wheel operations that
could cause the power steering system to over-
heat. 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 theInstruments 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

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.
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 theMainte-
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 by a NISSAN certified LEAF dealer.
Starting and driving5-21

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.The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving conditions,
the VDC system helps to perform the following
functions.
Controls brake pressure to reduce wheel slip 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 motor out- put 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 in-
put)
– oversteer (vehicle tends to spin due to cer- tain road or driving conditions) .
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.
When the VDC system operates, the
warning in the instrument panel flashes. When
the warning 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 sys-
tem is working properly.
Adjust your speed and driving according to the road conditions.
See VDC warning light in theInstruments and
controls section and VDC OFF indicator light
in the Instruments and controls section.
If a malfunction occurs in the system, the
warning illuminates in the lower display. The VDC
system automatically turns off when this warning
light is lit.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator
illuminates
to indicate that the VDC system is off. When the
VDC switch is used to turn off the system, the
VDC system still operates to prevent one drive
wheel from slipping by transferring power to a
drive wheel that is not slipping. The
warn-
ing flashes if this occurs. All other VDC functions
are off and the
warning will not flash. The
VDC System is automatically reset to ON when

The computer has a built-in diagnostic feature
that tests the system each time you start the EV
(Electric Vehicle) 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 indication of a malfunction.
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 tech-
niques. Reduce vehicle speed and be
especially careful when driving and
cornering on slippery surfaces and al-
ways drive carefully. Do not modify 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 ve-
hicle or are extremely deteriorated the
VDC system may not operate properly.
This could adversely affect vehicle
handling performance, and the
warning may flash ormay il-
luminate.
If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC system
may not operate properly and
may
illuminate.
If traction motor control related parts
are not NISSAN recommended or are
extremely deteriorated, the
may
illuminate.
When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
warning may illu-
minate. Do not drive on these types of
roads. When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
warning may illuminate.
This is not a malfunction. Restart the
EV (Electric Vehicle) system after driv-
ing onto a stable surface.
If wheels or tires other than the
NISSAN recommended ones are used,
the VDC system may not operate prop-
erly and the
warning may illumi-
nate.
The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
Starting and driving5-23

WARNING
If stopping for an emergency, be sure to move the vehicle well off the road.
Do not use the hazard warning flash- ers while moving on the highway un-
less unusual circumstances force you
to drive so slowly that your vehicle
might become a hazard to other traf-
fic.
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 state laws may prohibit the use of
the hazard warning flasher switch while
driving.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires. When the low tire pressure warn-
ing light is lit, and the CHECK TIRE PRESSURE
warning appears on the dot matrix liquid crystal
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 warning
light. This system will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h) . For more details, see Warning/
indicator lights and audible reminders in the
Instruments and controls section andTire
Pressure Monitoring System (TPMS) in the
Starting and driving section.
WARNING
Radio waves could adversely affect electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment manu-
facturer for the possible influences be-
fore 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 perma-
nently 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 injury. Check the tire
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label to turn
the low tire pressure warning light
OFF. If the light still illuminates while
driving after adjusting the tire pres-
sure, a tire may be flat. If you have a
flat tire, repair it as soon as possible.
When a wheel is replaced, the TPMS will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on after 1 minute. Contact a
NISSAN certified LEAF dealer as soon
as possible for tire replacement
and/or system resetting.
