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:
– Pedestrians that are small (for ex- ample, children), in a sitting posi-
tion, operating toys/skateboards,
on scooters or in wheelchairs, or
not in an upright standing or
walking position.
– Animals of any size.
–
Obstacles (for example, cargo or
debris) on the roadway or roadside.
– Oncoming or crossing vehicles.
–Vehicles where the tires are difficult
to see or the shape of the rear of the
vehicle is unclear or obstructed.
– Parked vehicles. •
The AEB with Pedestrian Detection
system has some performance limi-
tations.
– If a stationary vehicle is in the ve-
hicle’s path, the system will not
function when the vehicle ap-
proaches the stationary vehicle at
speeds over approximately 50
mph (80 km/h).
– Pedestrian detection will not
function when the vehicle is
driven at speeds over approxi-
mately 37 mph (60 km/h) or below
approximately 6 mph (10km/h).
• For pedestrians, the AEB with Pedes-
trian Detection system will not issue
the first warning.
• The AEB with Pedestrian Detection
system may not function properly or
detect a vehicle or pedestrians
ahead in the following conditions:
– In poor visibility conditions (such
as rain, snow, fog, dust storms,
sand storms, smoke, and road
spray from other vehicles).
– If dirt, ice, snow, fog or other ma-
terial is covering the radar sensor
area or camera area of
windshield. –
If a strong light (for example, sun-
light or high beams) enters the
front camera or a sudden change
in brightness occurs (for example,
entering a tunnel or driving in
lightning).
– In dark or dimly lit conditions,
such as at night or in tunnels, in-
cluding cases where your vehi-
cle’s headlights are off or dim, or
the tail lights of the vehicle ahead
are off.
– When the direction of the camera
is misaligned.
– When driving on a steep downhill
slope, on roads with sharp curves,
and/or bumpy or dirt roads.
– If there is interference by other ra-
dar sources.
– When your vehicle’s position or
movement is changed quickly or
significantly (for example, lane
change, turning vehicle, abrupt
steering, sudden acceleration or
deceleration).
5-140Starting and driving

–When your vehicle or the vehicle
or pedestrian ahead moves
quickly or significantly such that
the system cannot detect and re-
act in time (for example, pedes-
trian moving quickly toward the
vehicle at close range, vehicle cut-
ting in, changing lanes, making a
turn, steering abruptly, sudden
acceleration 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 par-
tially obscured or unidentifiable;
for example, due to transporting
luggage, pushing a stroller, wear-
ing bulky or very loose-fitting
clothing or accessories, or being
in a unique posture (such as rais-
ing 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 engine. –
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.
– While towing a trailer or other
vehicle.
• 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’s (radar and
camera) functionality, within certain
limitations. The system may not de-
tect some forms of obstruction of the
sensor 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 oncoming
vehicle in front of your vehicle.

SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
In the following conditions, the AEB with
Pedestrian Detection system warning light
blinks and the system will be turned off
automatically:
• The radar sensor picks up interferencefrom another radar source.
• The camera area of the windshield is misted or frozen.
• Strong light is shining from the front.
• The cabin temperature is over approxi- mately 104°F (40°C) in direct sunlight.
• The camera area of the windshield glass is continuously covered with dirt, etc.
Action to take
When the above conditions no longer exist,
the AEB with Pedestrian Detection system
will resume automatically.
NOTE:
When the inside of the windshield on the
camera area is misted or frozen, it will
take a period of time to remove it af ter
the A/C turns on. If dirt appears on this
area, it is recommended that you visit a
NISSAN dealer.

Starting and driving5-143

Action to take:
If the warning message appears, stop the ve-
hicle in a safe place, place the shif t lever in the
P (Park) position, and turn the engine off. When
the radar signal is temporarily interrupted,
clean the sensor area of the front bumper and
restart the engine. If the “Forward Driving Aids
temporarily disabled Front Sensor blocked
See Owner’s Manual” warning message con-
tinues to be displayed, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
Condition D
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snowfields, driving next to
long walls), the system may illuminate the
system warning light and display the “For-
ward Driving Aids Temporarily Disabled
Front Sensor Blocked See Owner’s Manual”
message.
Action to take:
When the above driving conditions no lon-
ger exist, turn the system back on.
NOTE:
If the AEB with Pedestrian Detection
system stops working, the I-FCW sys-
tem will also stop working.
SYSTEM MALFUNCTION
If the AEB with Pedestrian Detection sys-
tem malfunctions, it will be turned off auto-
matically, a chime will sound, the AEB with
Pedestrian Detection system warning light
(orange) will illuminate and the warning
message [Malfunction] will appear in the
vehicle information display.Action to take
If the warning light (orange) comes on, stop
the vehicle in a safe location, turn the en-
gine off and restart the engine. If the
warning light continues to illuminate, have
the AEB with Pedestrian Detection system
checked. It is recommended that you visit a
NISSAN dealer for this service.

SYSTEM MAINTENANCE
The radar sensor is located on the front of
the vehicle
OB. The camera is located on
the upper side of the windshield
OA.
To keep the AEB with Pedestrian Detection
system operating properly, be sure to ob-
serve the following:
• Always keep the sensor areas of the front bumper and windshield clean.
• Do not strike or damage the areas around the sensors (e.g., bumper,
windshield). • Do not cover or attach stickers, or install
any accessory near the sensors. This
could block sensor signals and/or cause
failure or malfunction.
• Do not attach metallic objects near the radar sensor (brush guard, etc.). This
could cause failure or malfunction.
• Do not place reflective materials, such as white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit's
detection capability.
• Do not alter, remove or paint the front bumper. Before customizing or restoring
the front bumper, it is recommended that
you visit a NISSAN dealer.
