• The low tire pressure warning light doesnot automatically turn off when the tire
pressure is adjusted. Af ter the tire is in-
flated to the recommended pressure, the
vehicle must be driven at speeds above
16 mph (25 km/h) to activate the TPMS
and turn off the low tire pressure warning
light. Use a tire pressure gauge to check
the tire pressure.
• The “Tire Pressure Low - Add Air” warning also appears on the vehicle information
display when the low tire pressure warn-
ing light is illuminated and low tire pres-
sure is detected. The “Tire Pressure Low -
Add Air” warning turns off when the low
tire pressure warning light turns off.
• The “Tire Pressure Low - Add Air” warning appears each time the power switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
• The “Tire Pressure Low - Add Air” warning does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction. • Tire pressure rises and falls depending on
the heat caused by operation of the ve-
hicle and the outside temperature. Do
not reduce the tire pressure af ter driving
because the tire pressure rises af ter driv-
ing. Low outside temperature can lower
the temperature of the air inside the tire,
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates in low ambient
temperature, check the tire pressure for
all four tires.
• The pressure of all tires can also be checked on the display screen. The order
of the tire pressure figures displayed on
the screen does not correspond with the
actual order of the tire position.
For additional information, see “Low tire
pressure warning light” (P. 2-20) and “Tire
Pressure Monitoring System (TPMS)” (P. 6-3).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
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 under-inflated 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 tire is
flat, repair it as soon as possible. For
additional information, see “Flat tire”
(P. 6-3).

TPMS with Easy-Fill Tire Alert
When tire pressure is low, the low tire pres-
sure warning light illuminates.
This vehicle provides visual and audible
signals to help you inflate the tires to the
recommended COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and push the P(Park) position switch on the shif t lever.
3. Place the power switch in the ON posi- tion. Do not place in the READY to drive
mode.
Operation:
1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the tire briefly to release pressure. When
the pressure reaches the designated
pressure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds af ter
starting to inflate 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 exter- nal device 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.
– There is a malfunction in the horn or hazard indicators.
– If the Easy-Fill Tire Alert does not op- erate due to TPMS interference,
move the vehicle about 3 f t (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 ve-
hicle to rollover, particularly if the loss of
control causes the vehicle to slide side-
ways. Be attentive at all times, and avoid
driving when tired. Never drive when under
the influence of alcohol or drugs (including
prescription or over-the-counter drugs
which may cause drowsiness). Always
wear your seat belt as outlined in “Seat
belts” (P. 7-6), and also instruct your passen-
gerstodoso.
Seat belts help reduce the risk of injury in col-
lisions and rollovers. In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seat belt.

WARNING
Failure to follow the warnings and in-
structions for proper use of the I-LI sys-
tem could result in serious injury or
death.
• The I-LI system will not steer the ve-
hicle or prevent loss of control. It is
the driver’s responsibility to stay
alert, drive safely, keep the vehicle in
the traveling lane, and be in control of
the vehicle at all times. •
The I-LI system is primarily intended
for use on well-developed freeways
or highways. It may not detect the
lane markers in certain road,
weather, or driving conditions.
The I-LI system must be turned on with the
ProPILOT Assist switch on the steering
wheel (models with ProPILOT Assist) or the
dynamic driver assistance switch (models
without ProPILOT Assist) every time the
power switch is placed in the ON position.
The I-LI system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The I-LI system warns the driver when the
vehicle has lef t the center of the traveling
lane with an indicator in the vehicle infor-
mation display and a steering vibration.
The system helps assist the driver to return
the vehicle to the center of the traveling
lane by applying the brakes to the lef t or
right wheels individually (for a short period
of time).
The I-LI system monitors the lane markers
on the traveling lane using the camera unit
OAlocated above the inside mirror.

WARNING
Failure to follow the warnings and in-
structions for proper use of the I-DA
system could result in serious injury or
death.
• The I–DA system is only a warning to
inform the driver of a potential lack
of driver attention or drowsiness. It
will not steer the vehicle or prevent
loss of control.
• The I–DA system does not detect and
provide an alert of the driver’s lack of
attention or fatigue in every
situation.
• It’s the driver’s responsibility to:
– stay alert,
– drive safely,
– keep the vehicle in the traveling
lane,
– be in control of the vehicle at all
times,
– avoid driving when tired,
– avoid distractions (texting, etc.). The I–DA system helps alert the driver if the
system detects a lack of attention or driv-
ing fatigue.
The system monitors driving style and
steering behavior over a period of time,
and it detects changes from the normal
pattern. If the system detects that driver
attention is decreasing over a period of
time, the system uses audible and visual
warnings to suggest that the driver take a
break.
I-DA SYSTEM OPERATION
If the system detects driver fatigue or that
driver attention is decreasing, the mes-
sage “Take a break?” appears in the vehicle
information display and a chime sounds
when the vehicle is driven at speeds above
37 mph (60 km/h).
The system continuously monitors driver
attention and can provide multiple warn-
ings per trip.
The system resets and starts reassessing
driving style and steering behavior when
the power switch is cycled from the ON to
the OFF position and back to the ON
position.

INTELLIGENT DRIVER ALERTNESS
(I-DA) (if so equipped)
Starting and driving5-149

• Drive at a constant speed. Maintain cruis-ing 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 acceleration 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 heating or cooling to help reduce
power consumption.
• Use the air conditioner/heater and close windows to reduce drag when cruising at
a 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 regen- erative brake system. The primary pur-
pose of the regenerative 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) posi-
tion, when the accelerator pedal is re-
leased, the regenerative brake system
provides some deceleration and some
power to the Li-ion battery. The ECO Drive Report appears for approxi-
mately 30 seconds af ter placing the power
switch in the OFF position, driving the ve-
hicle for more than 0.3 miles (500 m), and
pressing the
button on the steering
wheel.
ECO DRIVE REPORT
Starting and driving5-153

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, see “Power steering warning
light” (P. 2-23).
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
5-156Starting 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 place
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 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 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.
