DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
of the DCA system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.This system will not adapt automati-
cally to road conditions. Do not use
the system on roads with sharp
curves, or on icy roads, in heavy rain
or in fog.
.The DCA system will not apply brake
control while the driver’s foot is on
the accelerator pedal.
.As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive or absent-minded driving, or
overcome poor visibility in rain, fog,
or other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles..The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the DCA system
under the following conditions:
— On roads with sharp curves
— On slippery road surfaces such as
on ice or snow, etc.
— During bad weather (rain, fog,
snow, etc.)
— When rain, snow or dirt adhere to
the system sensor
— On steep downhill roads (fre-
quent braking may result in over-
heating the brakes)
— On repeated uphill and downhill
roads
.In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You
may need to control the distance
from other vehicles using the accel-
erator pedal. Always stay alert and
avoid using the DCA system when it
is not recommended in this section.The radar sensor will not detect the follow-
ing objects:
.Stationary and slow moving vehicles
.Pedestrians or objects in the roadway
.Oncoming vehicles in the same lane
.Motorcycles traveling offset in the travel
lane
The following are some conditions in which
the sensor cannot detect the signals:
.When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
.When excessively heavy baggage is
loaded in the rear seat or the trunk of
your vehicle

The detection zone of the sensor is limited. A
vehicle ahead must be in the detection zone
for the system to operate.
A vehicle ahead may move outside of the
detection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are
traveling offset from the centerline of the
lane. A vehicle that is entering the lane ahead
may not be detected until the vehicle has
completely moved into the lane.If this
occurs, the system may warn you by blink-
ing the system indicator and sounding the
chime. The driver may have to manually
control the proper distance away from
vehicle traveling ahead.

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 system
indicator and sounding the chime unexpect-
edly. You will have to manually control the
proper distance away from the vehicle
traveling ahead.

the DCA system will resume automatically.SYSTEM MALFUNCTION
When the DCA system is not operating
properly, the chime sounds, the driver assist
system forward indicator (orange) and the
system “malfunction” warning message will
appear in the vehicle information display.Action to take:
If the driver assist system forward indicator
(orange) and the warning message appear,
stop the vehicle in a safe place and place the
shift lever in the P (Park) position. 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
vehicle is still driveable under normal con-
ditions, have the vehicle checked. It is
recommended you visit an INFINITI retailer
for this service.
SYSTEM MAINTENANCE
The sensor for the DCA system is common
with the Intelligent Cruise Control (ICC)
system and is located behind the grille of
the front bumper.

WARNING
Failure to follow the warnings and
instructions for proper use of the FEB
with pedestrian detection system could
result in serious personal injury or death.
.The FEB with pedestrian detection
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
carelessness or dangerous driving
techniques.
.The FEB with pedestrian detection
system does not function in all driv-
ing, traffic, weather and road condi-
tions.
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.
JVS0865X
The FEB with pedestrian detection system
uses a radar sensorlocated behind the
grille of the front bumper to measure the
distance to the vehicle ahead in the same
lane.
For pedestrians, the FEB with pedestrian
detection system uses a camera
installed
behind the windshield in addition to the
radar sensor.

FEB WITH PEDESTRIAN DETEC-
TION SYSTEM OPERATION
The FEB with pedestrian detection system
operates at speeds above approximately 3
MPH (5 km/h). For the pedestrian detection
function, the system operates at speeds
between 6 – 37 MPH (10 – 60 km/h).
If a risk of a forward collision is detected, the
FEB with pedestrian detection system will
provide the first warning to the driver by
flashing the driver assist system forward
indicator (orange)
and the vehicle ahead
detection indicator (orange), and provid-
ing an audible warning. In addition, the FEB
with pedestrian detection system pushes the
accelerator pedal up, and then the system
applies partial braking. If the driver applies
the brakes quickly and forcefully, but the
FEB with pedestrian detection system de-
tects that there is still the possibility of a
forward collision, the system will automati-
cally increase the braking force.
If the risk of a collision becomes imminent
and the driver does not take action, the FEB
with pedestrian detection system issues the
second warning to the driver by flashing the
FEB system emergency warning indicator
(red)
, providing an audible warning, and
then automatically applies harder braking.
If a risk of a forward impact with a
pedestrian is detected, the FEB with pedes-
Page 327 of 492

trian detection system will provide a warning
to the driver by flashing the FEB system
emergency warning indicator (red)
, pro-
vides an audible alert and the system will
apply partial braking. If the driver applies the
brakes quickly and forcefully but the FEB
with pedestrian detection system detects
that there is still the possibility of a forward
impact with a pedestrian, the system will
automatically increase the braking force. If
the risk of collision becomes imminent and
the driver does not take action, the FEB with
pedestrian detection system automatically
applies harder braking.
NOTE:
The vehicle’s stop lights come on when any
braking is performed by the FEB with
pedestrian detection system.
Depending on vehicle speed and distance to
the vehicle or pedestrian 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
collision should one be unavoidable. If the
driver is handling the steering wheel, accel-
erating or braking, the FEB with pedestrian
detection system will function later or will
not function.
The automatic braking will cease under the
following conditions:.When the steering wheel is turned to
avoid a collision.
.When the accelerator pedal is depressed.
.When there is no longer a vehicle or a
pedestrian detected ahead.
If the FEB with pedestrian detection system
has stopped the vehicle, the vehicle will
remain at a standstill for approximately 2
seconds before the brakes are released.
