2022 NISSAN LEAF warning

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.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-164Starting and driving

When the VDC system operates, theindicator light in the instrument panel
flashes. When the indicator light flashes,
note the following items:
• The road may be slippery or the systemmay 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 indi-
cates that the VDC system is working
properly.
• Adjust your speed and driving according to the road conditions.
For additional information, see “Slip indica-
tor light” (P. 2-23) and “Vehicle Dynamic Con-
trol (VDC) OFF indicator light” (P. 2-24).
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
, along with the AEB with
Pedestrian Detection and RAB warning
lights illuminate to indicate that the VDC,
AEB with Pedestrian Detection, and RAB
systems are off. When the vehicle informa-
tion display is used to turn off the system,
the VDC system still operates to prevent
one drive wheel from slipping by transfer-
ring power to a non-slipping wheel. The
indicator light flashes if this occurs. All
other VDC functions are off and the
indicator light will not flash. The VDC sys-
tem is automatically reset to on when the
power switch is placed in the OFF position
then back to the ON position. For additional
information, see “Vehicle information dis-
play ” (P. 2-26).
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.
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 driv-
ing and cornering on slippery sur-
faces and always drive carefully.
•
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 deteriorated the VDC
system may not operate properly.
This could adversely affect vehicle
handling performance, and the
indicator light may flash or the
indicator 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 system
may not operate properly and the
indicator light may illuminate.

INTELLIGENT TRACE CONTROL
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to aid tracing at corners
and help smooth vehicle response.
The Intelligent Trace Control can be set to
on (enabled) or off (disabled) through the
vehicle information display “Settings” page.
For additional information, see “Vehicle in-
formation display” (P. 2-26).
When the VDC system is turned off in the
vehicle information display, the Intelligent
Trace Control is also turned off.When the Intelligent Trace Control is oper-
ated and the “Chassis Control” mode is se-
lected in the vehicle information display,
the Intelligent Trace Control graphics are
shown in the vehicle information display.
For additional information, see “Vehicle in-
formation display” (P. 2-26).
If the “Chassis Control System Error: See
Owner’s Manual” warning message ap-
pears in the vehicle information display, it
may indicate that the Intelligent Trace Con-
trol is not functioning properly. Have the
system checked as soon as possible. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for this service.
WARNING
The Intelligent Trace Control may not
be effective depending on the driving
condition. Always drive carefully and
attentively.
When the Intelligent Trace Control is oper-
ating, you may feel a pulsation in the brake
pedal, hear a noise and sense slight decel-
eration. This is normal and indicates that
the Intelligent Trace Control is operating
properly.
Even if the Intelligent Trace Control is
turned off, some functions will remain on to
assist the driver (for example, avoidance
scenes).
INTELLIGENT RIDE CONTROL
This system senses upper body motion
(based on wheel speed information) and
controls motor torque. This will enhance
ride comfort in effort to restrain uncom-
fortable upper body movement when
passing over undulated road surfaces. This
system comes into effect above 25 mph
(40 km/h).
When the VDC system is turned off in the
vehicle information display, the Intelligent
Ride Control is also turned off.

WARNING
The Intelligent Ride Control may not be
effective depending on the driving con-
dition. Always drive carefully and
attentively.
When the Intelligent Ride Control is operat-
ing, you may hear a noise and sense slight
deceleration. This is normal and indicates
that the Intelligent Ride Control is operat-
ing properly.
If the “Chassis Control System Error: See
Owner’s Manual” warning message ap-
pears in the vehicle information display, it
may indicate that the Intelligent Ride Con-
trol is not functioning properly. Have the
system checked as soon as possible. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for this service. The RSS sounds a tone to inform the driver
of obstacles near the bumper.
When the “DISPLAY” key is ON, the sonar
view will automatically appear in the in the
touch-screen display. An additional view of
the sonar status will appear in the vehicle
information display for reference.
WARNING
• The RSS is a convenience but it is not
a substitute for proper parking. •
The driver is always responsible for
safety during parking and other ma-
neuvers. Always look around and
check that it is safe to do so before
parking.
• Read and understand the limitations
of the RSS as contained in this sec-
tion. The colors of the sonar indicator
and the distance guide lines in the
rear view indicate different distances
to the object.
• Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck's compressed-air
brakes or a pneumatic drill may af-
fect the function of the system; this
may include reduced performance or
a false activation.
• This function is designed as an aid to
the driver in detecting large station-
ary objects to help avoid damaging
the vehicle.
• The system is not designed to pre-
vent contact with small or moving
objects. Always move slowly. The
system will not detect small objects
below the bumper, and may not de-
tect objects close to the bumper or
on the ground.

The system may not detect objects
at speeds above 3 mph (5 km/h) and
may not detect certain angular or
moving objects.
• Do not attach stickers (including
transparent material), install acces-
sories, or apply anything blocking
the sensors. These conditions may
reduce the ability of the system.
SYSTEM TEMPORARILY
UNAVAILABLE
When sonar blockage is detected, the sys-
tem will be deactivated automatically.
The system is not available until the condi-
tions no longer exist.
The sonar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the sonar
sensors.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
Starting and driving5-171

SYSTEM MAINTENANCE
The sonar sensorsO1are located on the
rear bumper. Always keep the area near
the sonar sensors clean.
The sonar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.
WARNING
• Never rely solely on the hill start as-
sist system to prevent the vehicle
from moving backward on a hill. Al-
ways drive carefully and attentively.
Depress the brake pedal when the
vehicle is stopped on a steep hill. Be
especially careful when stopped on a
hill on frozen or muddy roads. Failure
to prevent the vehicle from rolling
backwards may result in a loss of
control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and
may result in a collision or serious
personal injury.
• The hill start assist may not prevent
the vehicle from rolling backwards
on a hill under all load or road condi-
tions. Always be prepared to depress
the brake pedal to prevent the ve-
hicle from rolling backwards. Failure
to do so may result in a collision or
serious personal injury.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting
it into the key hole or use the remote key-
less entry key fob.
ANTIFREEZE
In the winter when it is possible that the
outside temperature will drop below 32°F
(0°C), check the antifreeze to ensure proper
winter protection. For additional informa-
tion, see “Cooling system” (P. 8-5).
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, see “12-volt battery” (P. 8-9).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system. Refill
before operating the vehicle. For additional
information, see “Cooling system” (P. 8-5).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads, NISSAN
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for the tire type, size,
speed rating and availability information.
For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may
be poorer than that of non-studded
snow tires.
Tire chains may be used. For additional in-
formation, see “Tire chains” (P. 8-33).
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-move ice and snow from the windows
and wiper blades.
• A shovel to dig the vehicle out of snow-drif ts.
• Extra windshield-washer fluid to refill the reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
• Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.
• Whatever the conditions, drive with
caution. Accelerate and slow down
with care. If accelerating too fast, the
drive wheels will lose even more
traction.
