2020 NISSAN LEAF power steering

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 oper-
ating.
• The TPMS will not activate the Easy-Fill Tire Alert under the following condi-
tions:– 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” in the “Safety — Seats, seat belts and
supplemental restraint system” section of
this manual, and also instruct your passen-
gerstodoso.

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 its 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.

1. Firmly apply the parking brake.
2. Push the P (Park) position switch on theshif t lever.
3. To help prevent the vehicle from rolling into the street when parked on a slope, it
is a good practice to turn the wheels as
illustrated.
• HEADED DOWNHILL WITH CURB
O1:
Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb. • HEADED UPHILL WITH CURB
O2:
Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.
• HEADED UPHILL OR DOWNHILL, NO CURB
O3:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the power switch in the OFF position.
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.

POWER STEERING SYSTEM
5-156Starting and driving

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.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.
BRAKE SYSTEM
Starting and driving5-157

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances 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 ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
• Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified 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.
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.
