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 driving5-83

•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 vehicle height
or the vehicle body inclination is
changed, the system may not de-
tect 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, 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.

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
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 driving,
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.

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 diffi- cult 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 func- tion when the vehicle is driven at
speeds over approximately 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 mate-
rial is covering the radar sensor
area or camera area of windshield.
– If 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,
including 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).
Starting and driving5-89

–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 partially
obscured or unidentifiable; for ex-
ample, due to transporting lug-
gage, pushing a stroller, wearing
bulky or very loose-fitting clothing
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 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.
• 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.
