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.
— On off-road surfaces such as on sand or rock, 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
— When towing a trailer or other vehicle
. 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
Starting and driving5-89

5-90Starting and driving
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 luggage
room 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.SYSTEM TEMPORARILY UNA-
VAILABLE

SENSOR MAINTENANCE
The sensor for the DCA systemis located
behind the grille of the front bumper.
The DCA system is designed to automati-
cally check the sensor’s operation. When the
sensor is covered with dirt or is obstructed,
the system will automatically be canceled. If
the sensor is covered with ice, a transparent
or translucent vinyl bag, etc., the DCA
system may not detect them. In these
instances, the DCA system may not be able
to decelerate the vehicle properly. Be sure to
check and clean the sensor regularly.
To keep the DCA 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.
. Do not attach metallic objects near the
sensor area (brush guard, etc.). This
could cause failure or malfunction.
. Do not alter, remove or paint the front
bumper. Before customizing or restoring
the front bumper, it is recommended you
contact an INFINITI retailer.

WARNING
Failure to follow the warnings and
instructions for proper use of the FEB
with pedestrian detection system could
result in serious 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.

FORWARD EMERGENCY BRAKING
(FEB) WITH PEDESTRIAN DETECTION

5-94Starting and driving
JVS1158X
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 system uses a
camera
installed behind the windshield in
addition to the radar sensor.WAF0320X

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
FEB with pedestrian detection system oper-
ates at speeds between 6 – 37 MPH (10 –
60 km/h).
If a risk of a forward collision with a vehicle is
detected, the FEB with pedestrian detection
system will firstly provide the warning to the
driver by blinking the vehicle ahead detection
indicator in the vehicle information display
and providing an audible alert. In addition,
the FEB with pedestrian detection system
pushes the accelerator pedal up. If the driver
releases the accelerator pedal, then the
system applies 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 collision, the system will automati-
cally increase the braking force.
If the risk of a forward collision becomes
imminent and the driver does not take
action, the FEB with pedestrian detection
system issues the second visual (flashing)
and audible alert, and then automatically
applies harder braking.If a risk of a forward impact with a
pedestrian is detected, the FEB with pedes-
trian detection system issues the second
visual (flashing) and 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 brak-
ing 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
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,
accelerating or braking, the FEB with pe-
destrian detection system will function later
or will not function.
The automatic braking will cease under the
following 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 or
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.
