power steering NISSAN LEAF 2019 Owner´s Manual

• The TPMS will activate only when the ve-hicle is driven at speeds above 16 mph
(25 km/h). Also, this system may not de-
tect a sudden drop in tire pressure (for
example, a flat tire while driving).
• The low tire pressure warning light does not 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 be-
cause the tire pressure rises af ter driving.
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, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section and “Tire Pressure
Monitoring System (TPMS)” in the “In case of
emergency” 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. Driv-
ing with under-inflated tires may per-
manently damage the tires and in-
crease 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 Infor-
mation label to turn the low tire pres-
sure warning light off. If the tire is flat,
repair it as soon as possible. (For ad-
ditional information, refer to “Flat tire”
in the “In case of emergency ” section
of this manual.)

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 than ap- proximately 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 externaldevice or transmitter.
– The air pressure from the inflation de- vice 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 oper- ate 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” in the “Safety — Seats, seat belts and
supplemental restraint system” section of
this manual, and also instruct your passen-
gerstodoso.
Starting and driving5-7

1. Remain calm and do not overreact.
2. Maintain a firm grip on the steeringwheel with both hands and try to hold a
straight course.
3. When appropriate, slowly release the ac- celerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe lo- cation off the road and away from traffic
if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service
to change the tire. For additional infor-
mation, refer to “Flat tire” in the “In case of
emergency” section of this manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of al-
cohol or drugs. Alcohol in the blood-
stream reduces coordination, delays
reaction time and impairs judgement. Driving af ter drinking alcohol in-
creases the likelihood of being in-
volved in an accident injuring yourself
and others. Additionally, if you are in-
jured in an accident, alcohol can in-
crease the severity of the injury.
NISSAN is committed to safe driving. How-
ever, you must choose not to drive under
the influence of alcohol. Every year thou-
sands of people are injured or killed in
alcohol-related accidents. Although the lo-
cal laws vary on what is considered to be
legally intoxicated, the fact is that alcohol
affects all people differently and most
people underestimate the effects of alco-
hol.
Remember, drinking and driving don’t mix!
That is true for drugs, too (over-the-
counter, prescription, and illegal drugs).
Do not drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.
WARNING
• Do not operate the power switch while driving the vehicle except in an
emergency. (The EV system shuts
down when the power switch is
pushed three consecutive times or
the power switch is pushed and held
for more than 2 seconds.) If the EV
system stops while the vehicle is be-
ing driven, this could lead to a crash
and serious injury.
• When turning off the power switch, make sure to shif t the shif t lever to
the P (Park) position even if the ve-
hicle is maintaining a stop and hold
using the e-pedal. This will prevent
the vehicle from moving or rolling
unexpectedly, which could result in
serious personal injury or property
damage.
Before operating the power switch, make
sure the vehicle is in the P (Park) position.

• Do not place reflective materials, such aswhite paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit. If the camera unit is dam-
aged due to an accident, it is recom-
mended that you visit a NISSAN certified
LEAF dealer.
WARNING
Failure to follow the warnings and in-
structions for proper use of the I-LI
system 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 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
Alocated 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 its the driver’s responsibility to: – stay alert,
– drive safely,
– keep the vehicle in the travelinglane,
– 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 driving5-139

• 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 driving5-143

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

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)

5-150Starting and driving

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.
