tem warning indicator
2Steering-wheel-mounted controls (lef t
side)
3Center display
When the shif t lever is in the R (Reverse)
position and the vehicle speed is less than
approximately 9 mph (15 km/h), the RAB
system operates.
If a risk of a collision with an obstacle is
detected when your vehicle is backing up,
the RAB system warning indicator will flash
in the vehicle information display, a red
frame will appear in the center display (for
vehicles with the Intelligent Around View
Monitor system), and the system will chime
three times. The system will then auto-
matically apply the brakes. Af ter the auto-
matic brake application, the driver must
depress the brake pedal to maintain brake
pressure.

•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 ve-
hicle height or the vehicle body in-
clination is changed, the system
may not detect 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.
Starting and driving5-133

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 system
may help the driver avoid a forward collision
or may help mitigate the consequences if a
collision should be unavoidable. 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 toavoid a collision.
• When the accelerator pedal is depressed.
• 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:
– 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.

WARNING
Failure to follow the warnings and in-
structions for proper use of the I-DA
system could result in serious injury or
death.
• The I–DA system is only a warning to
inform the driver of a potential lack
of driver attention or drowsiness. It
will not steer the vehicle or prevent
loss of control.
• The I–DA system does not detect and
provide an alert of the driver’s lack of
attention or fatigue in every
situation.
• It is the driver’s responsibility to:
– stay alert,
– drive safely,
– keep the vehicle in the traveling lane,
– be in control of the vehicle at all times,
– avoid driving when tired,
– avoid distractions (texting, etc.). The I–DA system helps alert the driver if the
system detects a lack of attention or driv-
ing fatigue.
The system monitors driving style and
steering behavior over a period of time,
and it detects changes from the normal
pattern. If the system detects that driver
attention is decreasing over a period of
time, the system uses audible and visual
warnings to suggest that the driver take a
break.

If the system detects driver fatigue or that
driver attention is decreasing, the mes-
sage “Take a break?” appears in the vehicle
information display and a chime sounds
when the vehicle is driven at speeds above
37 mph (60 km/h).
The system continuously monitors driver
attention and can provide multiple warn-
ings per trip.The system resets and starts reassessing
driving style and steering behavior when
the ignition switch is cycled from the ON to
the OFF position and back to the ON
position.

The AWD high temperature message may
be displayed while trying to free a stuck
vehicle due to increased oil temperature.
The driving mode may change to 2-wheel
drive. If this message is displayed, stop the
vehicle with the engine idling, as soon as it
is safe to do so. Then if the message turns
off, you can continue driving.The tire size message may be displayed if
there is a large difference between the di-
ameters of front and rear wheels. Pull off
the road in a safe area, with the engine
idling. Check that all tire sizes are the same,
that the tire pressure is correct and that
the tires are not excessively worn.
If any warning messages continue to be
displayed, have your vehicle checked. It is
recommended that you visit a NISSAN
dealer as soon as possible.
WARNING
• Do not drive beyond the perfor-
mance capability of the tires. Acceler-
ating quickly, sharp steering maneu-
vers or sudden braking may cause
loss of control, even with AWD
engaged.
• For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious personal injury or vehicle
damage.
