The FEB system uses a radar sensorlocated behind the lower grille of the front
bumper to measure the distance to the
vehicle ahead in the traveling lane.

FEB SYSTEM OPERATION
The FEB system operates at speeds above
approximately 3 MPH (5 km/h).
If a risk of a forward collision is detected, the
FEB system will provide the first warning to
the driver by blinking the vehicle ahead
detection indicator in the vehicle information
display and providing an audible warning. In
addition, the FEB system pushes the accel-
erator pedal up. If the driver releases the
accelerator pedal, then the system applies
partial braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB
system detects that there is still the possi-
bility of a forward collision, the system will
automatically increase the braking force.
If a forward collision is imminent and the
driver does not take action, the FEB system
issues the second visual (flashing) and
audible warning and automatically applies
harder braking.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB system.
Depending on vehicle speed and distance to
the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may
help mitigate the consequences of a collisionshould one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB system will
function later or will not function.
The automatic braking will cease under the
following conditions:
.
When the steering wheel is turned as far
as necessary to avoid a collision.
. When the accelerator pedal is depressed.
. When there is no longer a vehicle de-
tected ahead.
If the FEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the brakes
are released.

Perform the following steps to turn the FEB
system on or off.
1. Push the SETTING button
.
2. Touch [Driver Assistance].
3. Touch [Emergency Assist].
4. Touch [Forward emergency braking] to turn the system ON/OFF.
When the FEB system is turned off, the FEB
system warning light (orange)
illuminates.
NOTE:
The FEB system will be automatically
turned ON when the engine is restarted.
The PFCW system is integrated into the
FEB system. There is not a separate selec-
tion in the display for the PFCW system.
When the FEB system is turned off, the
PFCW system is also turned off.

FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the FEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.The FEB system cannot detect all
vehicles under all conditions.
. The radar sensor does not detect the
following objects:
— Pedestrians, animals or obstacles in the roadway
— Oncoming vehicles
— Crossing vehicles
. The radar sensor has some perfor-
mance limitations. If a stationary
vehicle is in the vehicle’s path, the
FEB system will not function when
the vehicle is driven at speeds over
approximately 45 MPH (70 km/h).
. The radar sensor may not detect a
vehicle ahead in the following condi-
tions:
— Dirt, ice, snow or other material covering the radar sensor. — Interference by other radar
sources.
— Snow or road spray from travel- ing vehicles.
— If the vehicle ahead is narrow (e.g. motorcycle)
— When driving on a steep downhill slope or roads with sharp curves.
. In some road or traffic conditions, the
FEB system may unexpectedly push
the accelerator pedal up or apply
partial braking. When acceleration is
necessary, continue to depress the
accelerator pedal to override the
system.
. Braking distances increase on slip-
pery surfaces.
. The system is designed to automati-
cally check the sensor’s functionality,
within certain limitations. The system
may not detect some forms of ob-
struction of the sensor area such as
ice, snow, 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
the sensor area regularly.
. Excessive noise will interfere with the
warning chime sound, and the chime may not be heard.

SSD0253
When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the sensor
may detect vehicles in a different lane, or
may temporarily not detect a vehicle travel-
ing ahead. This may cause the system to
work inappropriately.
The detection of vehicles may also be
affected by vehicle operation (steering man-
euver 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
unexpectedly. You will have to manually
control the proper distance away from the
vehicle traveling ahead.

SYSTEM TEMPORARILY UNA-
VAILABLE
Condition A
When the radar sensor picks up interference
from another radar source, making it im-
possible to detect a vehicle ahead, the FEB
system is automatically turned off. The FEB
system warning light (orange)
will illumi-
nate.
Action to take:
When the above conditions no longer exist,
the FEB system will resume automatically.

Condition B
In the following conditions, the FEB system
is automatically turned off. The FEB system
warning light (orange)
will illuminate and
the “FRONT RADAR OBSTRUCTION”
warning message will appear in the vehicle
information display.
. The sensor area on the front of the
vehicle is covered with dirt or is ob-
structed.
Action to take:
If the warning light (orange)
comes on,
stop the vehicle in a safe place, place the
shift lever in the P (Park) position and turn
the engine off. Clean the radar cover on
lower grille with a soft cloth, and restart the
engine. If the warning light continues to
illuminate, have the FEB system checked. It
is recommended you visit an INFINITI re-
tailer for this service.
. When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next
to long walls).
Action to take:
When the above conditions no longer exist,
the FEB system will resume automatically.
Condition C
When the accelerator pedal actuator detects
that the internal motor temperature is high,
the FEB system is automatically turned off.
The FEB system warning light (orange)
will illuminate.
Action to take:
When the above conditions no longer exist,
the FEB system will resume automatically.
Condition D
When VDC system is OFF, the FEB brake
will not operate. In this case only visible and
audible warning operates. The FEB system
warning light (orange) will illuminate.
Action to take:
When the above conditions no longer exist,
the FEB system will resume automatically.
SYSTEM MALFUNCTION
If the FEB system malfunctions, it will be
turned off automatically, a chime will sound,
the FEB system warning light (orange)
will
illuminate.
Action to take:
If the warning light (orange)
illuminates,
stop the vehicle in a safe location and place
the shift lever in the P (Park) position. Turn
the engine off and restart the engine. If the
warning light continues to illuminate, have the FEB system checked. It is recommended
you visit an INFINITI retailer for this service.

SYSTEM MAINTENANCE
The sensoris located behind the lower
grille of the front bumper.
To keep the system operating properly, be
sure to observe the following:
. Always keep the sensor area of the front
bumper clean.
. Do not strike or damage the areas around
the sensor.
. Do not cover or attach stickers or similar
objects on the front bumper near the
sensor area. This could cause failure or
malfunction.
. Do not attach metallic objects near the
sensor area (brush guard, etc.). This could cause failure or malfunction.
. Do not alter, remove or paint the front
bumper. It is recommended you contact
an INFINITI retailer before customizing
or restoring the front bumper.

safely and be in control of the vehicle
at all times.
The PFCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle ahead
in the same lane.
