ing message continues to be displayed,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
Condition C
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 “Not
Available: Front Radar Blocked” message.
Action to take:
When the above driving conditions no lon-
ger exist, turn the system back on.
NOTE:
If the AEB system stops working, the
I-FCW system will also stop working.
SYSTEM MALFUNCTION
If the AEB system malfunctions, it will be
turned off automatically, a chime will
sound, the AEB warning light (orange) will
illuminate and the warning message [Mal-
function] will appear in the vehicle informa-
tion 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 warn-
ing light continues to illuminate, have the
AEB system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
SYSTEM MAINTENANCE
The sensor1for the AEB is located on the
front of the vehicle.
To keep the system operating properly, be
sure to observe the following:
∙ Always keep the sensor area of the front bumper clean.
∙ Do not strike or damage the areas around the sensor.
∙ Do not cover or attach stickers or simi- lar objects on the front bumper near
the sensor area. This could cause failure
or malfunction.

AEB WITH PEDESTRIAN
DETECTION SYSTEM OPERATION
The AEB system operates at speeds above
approximately 3 mph (5 km/h). For the pe-
destrian detection function, the system
operates at speeds between6–37mph
(10 – 60 km/h).
If a risk of a forward collision is detected,
the AEB with Pedestrian Detection system
will firstly provide the warning to the driver
by flashing the vehicle ahead detection in-
dicator (yellow) in the vehicle information
display and providing an audible alert. If the
driver applies the brakes quickly and force-
fully af ter the warning, and the AEB with
Pedestrian Detection system detects that
there is still the possibility of a forward col-
lision, the system will automatically in-
crease the braking force.
LSD3281
Starting and driving5-139

If the driver does not take action, the AEB
with Pedestrian Detection system issues
the second visual (flashing) (red and white)
and audible warning. If the driver releases
the accelerator pedal, then the system ap-
plies partial braking. If the risk of a collision
becomes imminent, the AEB with Pedes-
trian Detection system applies harder
braking automatically.
While the AEB with Pedestrian Detection
system is operating, you may hear the
sound of brake operation. This is normal
and indicates that the AEB with Pedestrian
Detection system is operating properly.
NOTE:
The vehicle’s brake lights come on when
any braking is performed by the AEB
with Pedestrian Detection system.
Depending on vehicle speed and distance
to the vehicle or pedestrian ahead, as well
as driving and roadway conditions, the sys-
tem may help the driver avoid a forward
collision or may help mitigate the conse-
quences if a collision should be unavoid-
able. If the driver is handling the steering
wheel, accelerating or braking, the AEB with
Pedestrian Detection system will function
later or will not function.The automatic braking will cease under the
following conditions:
∙ When the steering wheel is turned to avoid a collision.
∙ When the accelerator pedal is de- pressed.
∙ When there is no longer a vehicle or a pedestrian detected ahead.
If the AEB with Pedestrian Detection sys-
tem has stopped the vehicle, the vehicle
will remain at a standstill for approximately
2 seconds before the brakes are released.

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 oth- erwise not in a full upright stand-
ing 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 vehi- cle’s path, the AEB with Pedestrian
Detection system will not function
when the vehicle is driven at
speeds over approximately
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 vehicle
ahead is narrow (for example, a
motorcycle).
∙ The AEB with Pedestrian Detection system may not function if the speed
difference between the two vehicles is
too small.
∙ The radar sensor AEB with Pedestrian 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)
5-142Starting and driving

– Driving on a steep downhill slopeor 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 the 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.
– A sudden change in brightness oc- curs. (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 trunk
room 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 covered
by 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 nec-
essary, depress the accelerator pedal
to override the system.
∙ Excessive noise will interfere with the warning chime sound, and the chime
may not be heard.
