DCA system, turn on the VDC, then push the
dynamic driver assistance switch.)
For additional information about the VDC
system, refer to “Vehicle Dynamic Control
(VDC) system” in this section.
● When ABS or VDC (including the TCS) is

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 engine 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 engine off, restart the engine,
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 driveable 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.

FORWARD EMERGENCY BRAKING
(FEB) (if so equipped)
5-106Starting and driving
Page 460 of 607
1. Vehicle ahead detection indicator
2. FEB system warning light
FEB SYSTEM OPERATION
The FEB system will function when your vehicle is
driven at speeds above approximately 3 mph
(5 km/h).
If a risk of a forward collision is detected, the FEB
system will provide an initial warning to the driver
by both a visual and audible alert.
If the driver applies the brakes quickly and force-
fully after the warning, and the FEB system de-
tects that there is still the possibility of a forward
collision, the system will automatically increase
the braking force. If the driver does not take
action, the FEB system issues the second visual
warning (red) and audible warning and also ap-
plies partial braking.
If the risk of a collision becomes imminent, the
FEB system applies harder braking automatically.
NOTE:
The vehicle’s brake lights come on when
braking is performed by the forward emer-
gency braking system.
LSD2612
Starting and driving5-107
Page 461 of 607
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 conse-
quences of a collision, should one be unavoid-
able. If the driver is handling the steering wheel,
accelerating or braking, the FEB system will func-
tion later or will not function.
The automatic braking will cease under the fol-
lowing 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 detected
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.

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 engine 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.
Starting and driving5-109
Page 463 of 607
●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 engine off. Clean
the radar cover on the 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 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 engine off and
restart the engine. If the warning light continues
to illuminate, have the FEB systems 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.
