I-FCW SYSTEM LIMITATIONS
WARNING
Listed below are the system limita-
tions for the I-FCW system. Failure to
operate the vehicle in accordance
with these system limitations could
result in serious injury or death.
.The I-FCW system cannot detect
all vehicles under all conditions.
. The radar sensor does not detect
the following objects: — Pedestrians, animals or obsta-
cles in the roadway
— Oncoming vehicles
— Crossing vehicles
. (Illustration A) The I-FCW system
does not function when a vehicle
ahead is a narrow vehicle, such as
a motorcycle.
. The radar sensor may not detect
a vehicle ahead in the following
conditions:
— Snow or heavy rain — Dirt, ice, snow or other materi-
al covering the radar sensor
— Interference by other radar sources
— Snow or road spray from tra- velling vehicles.
— Driving in a tunnel
— Towing a trailer
. (Illustration B) When the vehicle
ahead is being towed.
. (Illustration C) When the distance
to the vehicle ahead is too close,
the beam of the radar sensor is
obstructed.
. (Illustration D) When driving on a
steep downhill slope or roads
with sharp curves.
. The system is designed to auto-
matically check the sensor’s func-
tionality, within certain
limitations. The system may not
detect some forms of obstruction
of the sensor area such as ice,
snow, stickers, for example. In
these cases, the system may not
be able to warn the driver prop-
erly. Be sure that you check, clean
and clear the sensor area regu-
larly.

When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
radar sensor may detect vehicles in a
different lane, or may temporarily not
detect a vehicle traveling ahead. This
may cause the I-FCW system to work
inappropriately.
The detection of vehicles may also be
affected by vehicle operation (steering
maneuver or traveling position in the
lane, etc.) or vehicle condition. If this
occurs, the system may warn you by
blinking the vehicle ahead detection
indicator and sounding the chime un-
expectedly. You will have to manually
control the proper distance away from the vehicle traveling ahead.
SYSTEM TEMPORARILY UNAVAIL-
ABLE
Condition A
When the radar sensor picks up interfer-
ence from another radar source, making
it impossible to detect a vehicle ahead,

RAB SYSTEM LIMITATIONS
WARNING
Listed below are the system limita-
tions 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
obstacle while the accelerator or
brake pedal is depressed, the
function may not operate or the
start of the operation may be
delayed. The RAB system may
not operate or may not perform
sufficiently due to vehicle condi-
tions, driving conditions, the traf-
fic environment, the weather,
road surface conditions, etc. Do
not wait for the system to oper-
ate. Operate the brake pedal by
yourself as soon as necessary.
. If it is necessary to override RAB
operation, strongly press the ac-
celerator pedal.
. Always check your surroundings
and turn to check what is behind
you before and while backing up.
The RAB system detects station- ary objects behind the vehicle.
The RAB system does not detect
the following objects:
— Moving objects
— Low objects
— Narrow objects
— Wedge-shaped objects
— Complex-shaped objects
— Multiple object in close
— Objects close to the bumper
(less than approximately 1 ft
[30 cm])
— Objects that suddenly appear
— Thin objects such as rope, wire, chain, etc.
. The RAB system may not operate
for pedestrians or animals.
. 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 materials or snow, that have
soft 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 diagonal to the rear of the

SYSTEM MAINTENANCE
The sonar sensorsare located on the
rear bumper. Observe the following items
to ensure proper operation of the system:
. Always keep the sonar sensors clean.
. If the sonar sensors are dirty, wipe
them off with a soft cloth while being
careful to not damage them.
. The sonar sensors may be blocked by
temporary ambient conditions such
as splashing water, mist or fog. The
blocked condition may also be caused
by objects such as ice, frost or dirt
obstructing the sonar sensors. Check
for and remove objects obstructing
the area around the sonar sensors. .
Do not subject the area around the
sonar sensors to strong impact. Also,
do not remove or disassemble the
sonar sensors. If the sonar sensors
and peripheral areas are deformed in
an accident, etc., have the sonar
sensors checked. It is recommended
that you visit a NISSAN dealer for this
service.
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint on
the sonar sensors and their surround-
ing areas. This may cause a malfunc-
tion or improper operation.
. When washing the vehicle using a
high-pressure washer, do not apply
direct washer pressure on the sonar
sensors. This may cause a malfunction
of the sonar sensors.

mance or a false activation.
. The sonar system is designed as
an aid to the driver in detecting
large stationary objects to help
avoid damaging the vehicle.
. The sonar system is not designed
to prevent contact with small or
moving objects. Always move
slowly. The system will not detect
small objects below the bumper,
and may not detect objects close
to the bumper or on the ground.
. The sonar system may not detect
the following objects: fluffy ob-
jects such as snow, cloth, cotton,
glass-wool, etc.; thin objects such
as rope, wire and chain, etc.; or
wedge-shaped objects.
CAUTION
.Excessive noise (such as audio
system volume or an open vehi-
cle window) will interfere with the
tone and it may not be heard.
. The front and rear sonar detect
the distance between the vehicle
and the obstacle by detecting the
sound wave reflected from the
surface of an obstacle. When there is a sound such as horn, or
an ultrasonic source (such as
sonar of other vehicles) around
the vehicle, the sonar may not
detect objects properly.
. Keep the sonar (located on the
bumper fascia) free from snow,
ice and large accumulations of
dirt. Do not clean the sonar with
sharp objects. If the sensors are
covered, the accuracy of the so-
nar function will be diminished.
SYSTEM OPERATION
The system informs with a visual and
audible signal of front obstacles when the
shift lever is in the D (Drive) position and
both front and rear obstacles when the
shift lever is in the R (Reverse) position.
Sonar Operation TableWAF0775X
The system is deactivated at speeds
above 6 MPH (10 km/h). It is reactivated
at lower speeds.
The intermittent tone will stop after 3
seconds when an obstacle is detected by
only the corner sensor and the distance
does not change. The tone will stop when
the obstacle get away from the vehicle.
When the object is detected, the indicator
(green) appears and blinks and the tone
sounds intermittently. When the vehicle
moves closer to the object, the color of
the indicator turns yellow and the rate of
the blinking increases. When the vehicle is
very close to the object, the indicator
stops blinking and turns red, and the tone
