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

SSD0252
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.

. 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 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.

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.

TION SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the FEB with pedestrian detection
system. Failure to operate the vehicle in
accordance with these system limita-
tions could result in serious injury or
death.
.The FEB with pedestrian detection
system cannot detect all vehicles or
pedestrian under all conditions.
. The radar sensor FEB with pedes-
trian detection system does not de-
tect the following objects:
— Small pedestrians (including small children), animals and cyclists.
— Pedestrians in wheelchairs or using mobile transport such as
scooters, child-operated toys, or
skateboards.
— Pedestrians who are seated or otherwise not in a full upright
standing or walking position.
— Oncoming vehicles — Crossing vehicles
— Obstacles on the roadside
. The FEB with pedestrian detection
system has some performance limita-
tions.
— If a stationary vehicle is in the vehicle’s path, the FEB with pe-
destrian detection system will not
function when the vehicle is driven
at speeds over approximately 50
MPH (80 km/h).
— For pedestrian detection, the FEB with pedestrian detection
system will not function when
the vehicle is driven at speeds
over approximately 37 MPH (60
km/h) or below approximately 6
MPH (10km/h).
. The FEB with pedestrian detection
system will not function for pedes-
trians in darkness or in tunnels, even
if there is street lighting in the area.
. For pedestrians, the FEB with pedes-
trian detection system will not issue
the first warning and will not push
the accelerator pedal up.
. The FEB with pedestrian detection
system may not function if the vehi-
cle ahead is narrow (for example a motorcycle).
. The FEB with pedestrian detection
system may not function if speed
difference between the two vehicles
is too small.
. The radar sensor FEB with pedes-
trian detection system may not func-
tion properly or detect a vehicle
ahead in the following conditions:
— Poor visibility (conditions such as rain, snow, fog, dust storms,
sandstorms, and road spray from
other vehicles)
— Driving on a steep downhill slope or roads with sharp curves.
— Driving on a bumpy road surface, such as an uneven dirt road.
— If dirt, ice, snow or other material is covering the radar sensor area.
— Interference by other radar sources.
— The camera area of windshield is fogged up, or covered with dirt,
water drops, ice, snow, etc.
— Strong light (for example, sun- light or high beams from oncom-
ing vehicles) enters the front
camera. Strong light causes the
area around the pedestrian to be

cast in a shadow, making it diffi-
cult to see.
— A sudden change in brightness occurs. (For example, when the
vehicle enters or exits a tunnel or a
shaded area or lightning flashes.)
— The poor contrast of a person to the background, such as having
clothing color or pattern which is
similar to the background.
— The pedestrian’s profile is par- tially obscured or unidentifiable
due to the pedestrian transport-
ing luggage, wearing bulky or very
loose-fitting clothing or acces-
sories.
. The system performance may de-
grade in the following conditions:
— The vehicle is driven on a slippery road.
— The vehicle is driven on a slope.
— Excessively heavy baggage is loaded in the rear seat or the
trunk of your vehicle.
. The system is designed to automati-
cally check the sensor (radar and
camera)’s functionality, within cer-
tain limitations. The system may not
detect blockage of sensor areas cov- ered by ice, snow or 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 sensor areas regularly.
. In some road and traffic conditions,
the FEB with pedestrian detection
system may unexpectedly apply par-
tial braking. When acceleration is
necessary, depress the accelerator
pedal to override the system.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
