Condition B:
When the sensor area of the front bumper is dirty,
making it impossible to detect a vehicle ahead,
the DCA system is automatically canceled.
The chime sounds and the system warning light
(orange) will come on and the “Sensor Blocked”
indicator will appear.
Action to take:
If the warning light comes on, park the vehicle in a
safe place, turn the hybrid system off. Clean the
sensor area of the bumper and then perform the
settings again.Condition C:
When the DCA system is not operating properly,
the chime sounds and the system warning light
(“DCA” orange) will come on.
Action to take:
If the warning light comes on, park the vehicle in a
safe place. Turn the hybrid system off, restart the
hybrid system, and turn on the DCA system
again.If it is not possible to set the system or the
indicator stays on, it may indicate that the
system is malfunctioning. Although the ve-
hicle is still drivable under normal condi-
tions, have the vehicle checked. It is recom-
mended that you visit an INFINITI retailer
for this service.
SYSTEM MAINTENANCE
The sensor for the DCA system is common with
ICC and is located behind the front bumper.
For additional information, refer to “Intelligent
Cruise Control (ICC)” in this section.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the FEB system
could result in serious injury or death.
●The FEB 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 care-
lessness or dangerous driving
techniques.
● The FEB system does not function in all
driving, traffic, weather and road
conditions.
The FEB system can assist the driver when there
is a risk of a forward collision with the vehicle
ahead in the traveling lane. The FEB system uses a radar sensor
Alocated
behind the lower grille of the front bumper to
measure the distance to the vehicle ahead in the
same lane.

TURNING THE FEB SYSTEM
ON/OFF
When the FEB system is enabled in the vehicle
information display, the system can be turned off
temporarily by pushing the warning systems
switch. For additional information, refer to “Warn-
ing systems switch” in the “Instruments and con-
trols” section of this manual.
Perform the following steps to turn the FEB sys-
tems ON or OFF.1. Press the
button until “Settings” dis-
plays in the vehicle information display and
then press ENTER button. Use the
button to select “Driver Assistance”. Then
press the ENTER button.
2. Select “Emergency Braking” and press the ENTER button.
3. Select “System” and press the ENTER but- ton.
When the FEB system is turned off, the FEB
system warning light illuminates.
NOTE:
● The FEB system will be automatically turned
on when the hybrid system is restarted. ●
The PFCW system (if so equipped) is inte-
grated into the FEB system. There is not a
separate selection in the vehicle information
display for the PFCW system. When the
FEB 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 ve-
hicles 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 ve-
hicle is in the vehicles’s path, the FEB
system will not function when the ve-
hicle is driven at speeds over approxi-
mately 50 mph (80 km/h).
● The radar sensor may not detect a ve-
hicle ahead in the following conditions:
– Dirt, ice, snow or other material cov- ering the radar sensor.
– Interference by other radar sources.
– Snow or road spray from traveling 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 apply
partial braking. When acceleration is
necessary, continue to depress the ac-
celerator pedal to override the system.
● Braking distances increase on slippery
surfaces.

●The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstructions of
the sensor area such as ice, snow, stick-
ers, etc. In these cases, the system may
not be able to worn 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.

SYSTEM TEMPORARILY
UNAVAILABLE
Condition A
When the radar sensor picks up interference
from another radar source, making it impossible
to detect a vehicle ahead, the FEB system is
automatically turned off.
The FEB system warning light (orange) will illu-
minate.
Action to take
When the above conditions no longer exist, the
FEB system will resume automatically.
Condition B
When the sensor area of the front bumper is
covered with dirt or is obstructed, making it im-
possible to detect a vehicle ahead, the FEB sys-
tem is automatically turned off.
The FEB system warning light (orange) will illu-
minate and the “front radar obstruction” warning
message will appear in the vehicle information
display.
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 hybrid system off.Clean the radar cover on the lower grille with a
soft cloth, and restart the hybrid system. If the
warning light continues to illuminate, have the
FEB system checked. It is recommended that you
visit an INFINITI retailer for this service.
NOTE:
If the FEB system stops working, the PFCW
system (if so equipped) will also stop work-
ing.
SYSTEM MALFUNCTION
If the FEB system malfunctions, it will be turned
off automatically, a chime will sound, the FEB
warning light (orange) will illuminate and the
warning message [Malfunction] will appear in the
vehicle information display.
Action to take
If the warning light (orange) comes on, stop the
vehicle in a safe location, turn the hybrid system
off and restart the hybrid system. If the warning
light continues to illuminate, have the FEB sys-
tems checked. It is recommended that you visit
an INFINITI retailer for this service.
SYSTEM MAINTENANCE
The radar sensorAis 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.

hicle ahead in the following conditions:
– Snow or heavy rain
– Dirt, ice, snow or other material cov- ering the radar sensor.
– Interference by other radar sources. – Snow or road spray from traveling
vehicles.
– Driving in a tunnel
– (Illustration B) When the vehicle ahead is being towed.
