AEB WITH PEDESTRIAN
DETECTION SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the AEB with Pedestrian Detection
system. Failure to operate the vehicle in
accordance with these system limita-
tions could result in serious injury or
death.
• The AEB with Pedestrian Detection
system cannot detect all vehicles or
pedestrians under all conditions.
• The AEB with Pedestrian Detection
system does not detect the following
objects:
– Small pedestrians (including
small children), animals and
cyclists.
– Pedestrians in wheelchairs or us-
ing mobile transport such as
scooters, child-operated toys, or
skateboards.
– Pedestrians who are seated or
otherwise not in a full upright
standing or walking position.
– Oncoming vehicles
– Crossing vehicles –
Obstacles on the roadside
• The AEB with Pedestrian Detection
system has some performance
limitations.
– If a stationary vehicle is in the ve-
hicle’s path, the AEB with Pedes-
trian Detection system will not
function when the vehicle is
driven at speeds over approxi-
mately 50 mph (80 km/h).
– For pedestrian detection, the AEB
with Pedestrian Detection system
will not function when the vehicle
is driven at speeds over approxi-
mately 37 mph (60 km/h) or below
approximately 6 mph (10 km/h).
• The AEB with Pedestrian Detection
system will not function for pedestri-
ans in darkness or in tunnels, even if
there is street lighting in the area.
• The AEB with Pedestrian Detection
system may not function if the ve-
hicle ahead is narrow (for example, a
motorcycle).
• The AEB with Pedestrian Detection
system may not function if speed dif-
ference between the two vehicles is
too small. •
The radar sensor AEB with Pedes-
trian Detection system may not
function properly or detect a vehicle
ahead in the following conditions:
– Poor visibility (conditions such as
rain, snow, fog, dust storms, sand-
storms, and road spray from other
vehicles)
– Driving on a steep downhill slope
or roads with sharp curves.
– Driving on a bumpy road surface,
such as an uneven dirt road.
– If dirt, ice, snow or other material
is covering the radar sensor area.
– Interference by other radar
sources.
– The camera area of windshield is
fogged up, or covered with dirt,
water drops, ice, snow, etc.
– Strong light (for example, sunlight
or high beams from oncoming ve-
hicles) enters the front camera.
Strong light causes the area
around the pedestrian to be cast
in a shadow, making it difficult to
see.
Starting and driving5-129

–A sudden change in brightness
occurs (for example, when the ve-
hicle enters or exits a tunnel or a
shaded area or lightning flashes).
– The poor contrast of a person to
the background, such as having
clothing color or pattern which is
similar to the background.
– The pedestrian’s profile is partially
obscured or unidentifiable due to
the pedestrian transporting lug-
gage, wearing bulky or very loose
fitting clothing or accessories.
• The system performance may de-
grade 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’s (radar and
camera) functionality, within certain
limitations. The system may not de-
tect blockage of sensor areas cov-
ered by ice, snow or stickers, for ex-
ample. 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.
• Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
• The AEB with Pedestrian Detection
system may react to a person on a
bicycle, detecting as a pedestrian. •
The AEB with Pedestrian Detection
system may operate under the fol-
lowing conditions, detecting the
possibility of a forward collision:
– A vehicle or a person is on the
roadside at the beginning of a
curve.
– A pedestrian approaches the driv-
ing lane in front of the vehicle.

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.
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, please refer to “Rear
Sonar System” in this section.

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.

SYSTEM MAINTENANCE
Observe the following items to ensure
proper operation of the system:
• Always keep the parking sensors
O1
clean.
• If the parking sensors are dirty, wipe them off with a sof t cloth while being careful to
not damage them. • Do not subject the area around the park-
ing sensors
O1to strong impact. Also, do
not remove or disassemble the parking
sensors. If the parking sensors and pe-
ripheral areas are deformed in an acci-
dent, etc., have the sensors checked. It is
recommended that you visit a NISSAN
certified LEAF dealer for this service.
• Do not install any stickers (including transparent stickers) or accessories on
the parking sensors
O1and their sur-
rounding areas. This may cause a mal-
function or improper operation.
WARNING
Failure to follow the warnings and in-
structions for proper use of the I-FCW
system could result in serious injury or
death.
• The I-FCW system can help warn the
driver before a collision occurs but
will not avoid a collision. It is the driv-
er’s responsibility to stay alert, drive
safely and be in control of the vehicle
at all times.
The I-FCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle
ahead in the same lane.
