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, and the RAB sys-
tem warning light will illuminate in the ve-
hicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.

• 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
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 AEB
with Pedestrian Detection system
could result in serious injury or death.
• The AEB with Pedestrian Detection
system is a supplemental aid to the
driver. It is not a replacement for the
driver’s attention to traffic condi-
tions or responsibility to drive safely.
It cannot prevent accidents due to
carelessness or dangerous driving
techniques.
• The AEB with Pedestrian Detection
system does not function in all driv-
ing, traffic, weather and road
conditions.
The AEB with Pedestrian Detection system
can assist the driver when there is a risk of
a forward collision with the vehicle ahead in
the traveling lane or with a pedestrian
ahead in the traveling lane. The AEB with Pedestrian Detection system
uses a radar sensor located on the front of
the vehicle
OBto measure the distance to
the vehicle ahead in the same lane. For
pedestrians, the AEB with Pedestrian De-
tection system uses a camera installed be-
hind the windshield
OAin addition to the
radar sensor.

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 the speed
difference 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 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
occurs. (For example, when the
vehicle 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.

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 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
