2022 NISSAN LEAF sensor

–When your vehicle or the vehicle or
pedestrian ahead moves quickly
or significantly such that the sys-
tem cannot detect and react in
time (for example, pedestrian
moving quickly toward the vehicle
at close range, vehicle cutting in,
changing lanes, making a turn,
steering abruptly, sudden accel-
eration or deceleration).
– When the vehicle or pedestrian is
offset from the vehicle’s forward
path.
– If the speed difference between
the two vehicles is small.
– The pedestrian’s profile is partially
obscured or unidentifiable; for ex-
ample, due to transporting lug-
gage, pushing a stroller, wearing
bulky or very loose-fitting cloth-
ing or accessories, or being in a
unique posture (such as raising
hands).
– There is poor contrast of a person
to the background, such as having
clothing color or pattern which is
similar to the background.
– For approximately 15 seconds af-
ter starting the EV system. –
If the vehicle ahead has a unique
or unusual shape, extremely low
or high clearance heights, or un-
usual cargo loading or is narrow
(for example, a motorcycle).
– When the vehicle or pedestrian is
located near a traffic sign, a reflec-
tive area (for example, water on
road), or is in a shadow.
– When multiple pedestrians are
grouped together.
– When the view of the pedestrian is
obscured by a vehicle or other
object.
• The system performance may be de-
graded in the following conditions:
– The vehicle is driven on a slippery
road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is
loaded in the rear seat or the
cargo area of your vehicle.
•
The system is designed to automati-
cally check the sensor (radar and cam-
era)’s functionality, within certain limi-
tations. The system may not detect
some forms of obstruction of the sen-
sor area such as ice, snow or stickers,
for example. In these cases, the system may not be able to warn the
driver properly. Be sure that you check,
clean and clear sensor areas regularly.
•
In some road and traffic conditions,
the AEB with Pedestrian Detection
system may unexpectedly apply par-
tial braking. When acceleration is
necessary, depress the accelerator
pedal to override the system.
• The AEB with Pedestrian Detection
system may operate when a pattern,
object, shadow or lights are detected
that are similar to the outline of ve-
hicles or pedestrians, or if they are
the same size and position as a ve-
hicle or motorcycle’s tail lights.
• The system may keep operating
when the vehicle ahead is turning
right or lef t.
• The system may operate when your
vehicle is approaching and passing a
vehicle ahead.
• Depending on the road shape
(curved road, entrance and exit of the
curve, winding road, lane regulation,
under construction, etc.), the system
may operate temporarily for the on-
coming vehicle in front of your
vehicle.

FCC Notice
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user’s author-
ity to operate the equipment.WARNING
Failure to follow the warnings and in-
structions for proper use of the RAB
system could result in serious injury or
death.
• The RAB system is a supplemental
aid to the driver. It is not a replace-
ment for proper driving procedures.
Always use the side and rear mirrors
and turn and look in the direction you
will move before and while backing
up. Never rely solely on the RAB sys-
tem. It is the driver’s responsibility to
stay alert, drive safely, and be in con-
trol of the vehicle at all times.
• There is a limitation to the RAB sys-
tem capability. The RAB system is not
effective in all situations.
• 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.
The RAB system can assist the driver when
the vehicle is backing up and approaching
objects directly behind the vehicle. The RAB system detects obstacles behind
the vehicle using the parking sensors
O1
located on the rear bumper.
NOTE:
You can temporarily cancel the sonar
function in the vehicle, but the RAB sys-
tem will continue to operate. For addi-
tional information, see “Rear Sonar Sys-
tem (RSS) (P. 5-168).

RAB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the RAB system. Failure to follow the
warnings and instructions for proper
use of the RAB system could result in
serious injury or death.
• When the vehicle approaches an ob-
stacle while the accelerator or brake
pedal is depressed, the function may
not operate or the start of operation
may be delayed. The RAB system
may not operate or may not perform
sufficiently due to vehicle conditions,
driving conditions, the traffic envi-
ronment, the weather, road surface
conditions, etc. Do not wait for the
system to operate. Operate the brake
pedal by yourself as soon as
necessary.
• If it is necessary to override RAB op-
eration, strongly press the accelera-
tor pedal. •
Always check your surroundings and
turn to check what is behind you be-
fore and while backing up. The RAB
system detects stationary objects
behind the vehicle. The RAB system
does not detect the following ob-
jects:
– Moving objects
– Low objects
– Narrow objects
– Wedge-shaped objects
– Objects close to the bumper (less
than approximately 1 f t [30 cm])
– Objects that suddenly appear
– Thin objects such as rope, wire,
chain, etc.
• The RAB system may not operate for
the following obstacles:
– Obstacles located high off the
ground
– Obstacles in a position offset from
your vehicle
– Obstacles, such as spongy materi-
als or snow, that have sof t outer
surfaces and can easily absorb a
sound wave •
The RAB system may not operate in
the following conditions:
– There is rain, snow, ice, dirt, etc.,
attached to the sonar sensors.
– A loud sound is heard in the area
around the vehicle.
– The surface of the obstacle is di-
agonal to the rear of the vehicle.
• The RAB system may unintentionally
operate in the following conditions:
– There is overgrown grass in the
area around the vehicle.
– There is a structure (e.g., a wall, toll
gate equipment, a narrow tunnel,
a parking lot gate) near the side of
the vehicle.
– There are bumps, protrusions, or
manhole covers on the road
surface.
– The vehicle drives through a
draped flag or a curtain.
– There is an accumulation of snow
or ice behind the vehicle.
– An ultrasonic wave source, such as
another vehicle’s sonar, is near
the vehicle.
Starting and driving5-139

•Once the automatic brake control
operates, it does not operate again if
the vehicle approaches the same
obstacle.
• The automatic brake control can only
operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
• In the following situations, the RAB
system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad
weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep
hill.
– The vehicle’s posture is changed
(e.g., when driving over a bump).
– The vehicle is driven on a slippery
road.
– The vehicle is turned sharply by
turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN
recommended are used.
– The brakes are cold at low ambi-
ent temperatures or immediately
af ter driving has started. –
The braking force becomes poor
due to wet brakes af ter driving
through a puddle or washing the
vehicle.
• Turn the RAB system off in the follow-
ing conditions to prevent the occur-
rence of an unexpected accident re-
sulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed
truck.
– The vehicle is on the chassis
dynamometer.
– The vehicle drives on an uneven
road surface.
– The vehicle is towing an object (if
so equipped).
– Suspension parts other than
those designated as Genuine
NISSAN parts are used. (If the ve-
hicle height or the vehicle body in-
clination is changed, the system
may not detect an obstacle
correctly.)
– If the vehicle is using an accessory
like a bike rack, or cargo carrier
that blocks the sensors. •
Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “Mal-
function: See Owner’s Manual” warning
message will appear in the vehicle infor-
mation display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the EV system
off, and restart the EV system. If the warn-
ing light continues to illuminate, have the
RAB system checked. It is recommended
that you visit a NISSAN certified LEAF dealer
for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.
