When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the sensor may detect ve-
hicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may cause
the 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 system indicator and sounding
the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.Approach warning
If your vehicle comes closer to the vehicle ahead
due to rapid deceleration of that vehicle or if
another vehicle cuts in, the system warns the
driver with the chime and DCA system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection indicator blinks. The warning chime may not sound in some cases
when there is a short distance between vehicles.
Some examples are:
● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.

NOTE:
The approach warning chime may sound
and the system display may blink when ICC
sensor detects vehicles in other lanes
Aor
objects on the side of the road
A. This may
cause the DCA system to operate inappro-
priately. The ICC sensor may detect these
objects when the vehicle is driven on wind-
ing roads, narrow roads, hilly roads or when
entering or exiting a curve. In these cases
you will have to manually control the
proper distance ahead of your vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condition
(for example, if a vehicle is being driven with some
damage) .
SYSTEM TEMPORARILY

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.

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)
Starting and driving5-107
Page 486 of 651
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
5-108Starting and driving
Page 487 of 651
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.

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.
