WARNING
Failure to follow the warnings and instruc-
tions for proper use of the RAB system
could result in serious injury or death.
• The RAB system is a supplemental aid to
the driver. It is not a replacement for
proper driving procedures. Always use
the side and rear mirrors and turn and
look in the direction you will move before
and while backing up. Never rely solely
on the RAB system. It is the driver’s
responsibility to stay alert, drive safely,
and be in control of the vehicle at all
times.
• Inclement weather or ultrasonic sources
such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
• There is a limitation to the RAB system
capability. The RAB system is not effec-
tive in all situations.
The RAB system can assist the driver when
the vehicle is backing up and approaching
objects directly behind the vehicle. The RAB system detects obstacles behind
the vehicle using the parking sensors
O1lo-
cated on the rear bumper.
NOTE:
You can temporarily cancel the sonar func-
tion in the vehicle, but the RAB system will
continue to operate. For additional infor-
mation, see “Front and rear sonar system”
(P. 5-147).

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 in-
jury 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 oper-
ate or may not perform sufficiently due
to vehicle conditions, driving conditions,
the traffic environment, 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 opera-
tion, strongly press the accelerator pedal.
• Always check your surroundings and
turn to check what is behind you before
and while backing up. The RAB system
detects stationary objects behind the
vehicle. The RAB system does not detect
the following objects:
– Moving objects
– Low objects –
Narrow objects
– Wedge-shaped objects
– 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 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., at-
tached to the sonar sensors.
– A loud sound is heard in the area
around the vehicle.
– The surface of the obstacle is diago-
nal to the rear of the vehicle.
• The RAB system may unintentionally op-
erate 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.
• Once the automatic brake control oper-
ates, it does not operate again if the ve-
hicle approaches the same obstacle.
• The automatic brake control can only
operate for a short period of time. There-
fore, the driver must depress the brake
pedal.
• In the following situations, the RAB sys-
tem 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).
Starting and driving5-107

–The vehicle is driven on a slippery
road.
– The vehicle is turned sharply by turn-
ing the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than INFINITI
recommended are used.
– The brakes are cold at low ambient
temperatures or immediately after
driving has started.
– The braking force becomes poor due
to wet brakes after driving through a
puddle or washing the vehicle.
• Turn the RAB system off in the following
conditions to prevent the occurrence of
an unexpected accident resulting from
sudden system operation:
– The vehicle is towed.
–
The vehicle is carried on a flatbed truck.
– The vehicle is on the chassis dyna-
mometer.
– The vehicle drives on an uneven road
surface.
– Suspension parts other than those
designated as Genuine INFINITI
parts are used. (If the vehicle height
or the vehicle body inclination is
changed, the system may not detect
an obstacle correctly.) –
The vehicle is towing an object (if so
equipped).
– If a vehicle is using an accessory like a
bike rack, or cargo carrier that blocks
the sensors.
• Excessive noise (e.g., audio system vol-
ume, an open vehicle window) will inter-
fere with the chime sound, and it may not
be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “System
fault” warning message will appear in the
vehicle 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 system
checked. It is recommended that you visit an
INFINITI retailer for this service.
NOTE:
If the RAB system cannot be operated tempo-
rarily, the RAB system warning light blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure proper
operation of the system:
• Always keep the parking sensors
O1clean.
• If the parking sensors are dirty, wipe them off with a soft cloth while being careful to
not damage them.
• Do not subject the area around the parking sensors
O1to strong impact. Also, do not
remove or disassemble the parking sensors.

If the parking sensors and peripheral areas
are deformed in an accident, etc., have the
sensors checked. It is recommended that
you visit an INFINITI retailer for this service.
• Do not install any stickers (including trans- parent stickers) or accessories on the park-
ing sensors
O1and their surrounding areas.
This may cause a malfunction or improper
operation.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the FEB with Pedes-
trian Detection system could result in seri-
ous injury or death.
• The FEB with Pedestrian Detection sys-
tem is a supplemental aid to the driver. It
is not a replacement for the driver’s at-
tention to traffic conditions or responsi-
bility to drive safely. It cannot prevent
accidents due to carelessness or danger-
ous driving techniques.
• The FEB with Pedestrian Detection sys-
tem does not function in all driving, traf-
fic, weather and road conditions.
The FEB 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 FEB with Pedestrian Detection system
uses a radar sensor
OAlocated on the front of
the vehicle to measure the distance to the
vehicle ahead in the same lane. For pedestri-
ans, the FEB with Pedestrian Detection sys-
tem uses a camera
OBinstalled behind the
windshield in addition to the radar sensor.

upright standing or walking position.
– Animals of any size.
– Obstacles (for examples, cargo or de- bris) 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 FEB with Pedestrian Detection sys-
tem has some performance limitations.
– If a stationary vehicle is in the vehi- cle’s path, the FEB with Pedestrian
Detection system will not function
when the vehicle approaches the sta-
tionary vehicle at speeds over ap-
proximately 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 FEB with Pedes-
trian Detection system will not issue the
first warning.
• The FEB with Pedestrian Detection sys-
tem may not function properly or detect
a vehicle or pedestrian ahead in the fol-
lowing 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 material is covering the radar sensor area or
camera area of windshield. – If strong light (for example, sunlight
or high beams) enters the front cam-
era or a sudden change in brightness
occurs (for example, entering a tun-
nel or driving in lightning).
– In dark or dimly lit conditions, such as at night or in tunnels, including cases
where your vehicle’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 radar sources.
– When your vehicle’s position or movement is changed quickly or sig-
nificantly (for example, lane change,
turning vehicle, abrupt steering, sud-
den acceleration or deceleration).
Starting and driving5-113

– When your vehicle or the vehicle orpedestrian ahead moves quickly or
significantly such that the system
cannot detect and react in time (for
example, pedestrian moving quickly
toward the vehicle at close range, ve-
hicle cutting in, changing lanes, mak-
ing a turn, steering abruptly, sudden
acceleration or deceleration).
– When the vehicle or pedestrian is off-
set 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 luggage,
pushing a stroller, wearing bulky or
very loose-fitting clothing or acces-
sories, 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 after
starting the engine.
– If the vehicle ahead has a unique or unusual shape, extremely low or high
clearance heights, or unusual cargo
loading or is narrow (for example, a
motorcycle). – When the vehicle or pedestrian is lo-
cated near a traffic sign, a reflective
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 automatically
check the sensor’s (radar and camera)
functionality, within certain limitations.
The system may not detect 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
FEB with Pedestrian Detection system
may unexpectedly apply partial braking.
When acceleration is necessary, depress
the accelerator pedal to override the
system.
• The FEB with Pedestrian Detection sys-
tem may operate when a pattern, object,
shadow or lights are detected that are
similar to the outline of vehicles or pe-
destrians, or if they are the same size and
position as a vehicle or motorcycle’s tail
lights.
• The system may keep operating when
the vehicle ahead is turning right or left.
• The system may operate when your ve-
hicle 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.
