The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelera-
tor pedal upward in the normal driving
condition.
When a vehicle ahead is detected:
The vehicle ahead detection indicator ap-
pears.When the vehicle approaches a vehicle
ahead:
.If the driver’s foot is not on the accel-
erator pedal, the system activates the
brakes to decelerate smoothly as neces-
sary. If the vehicle ahead comes to a
stop, the vehicle decelerates to a stand-
still within the limitations of the system.
.If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward to assist the driver to
release the accelerator pedal.
When brake operation by the driver is
required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead detec-tion indicator. If the driver’s foot is on the
accelerator pedal after the warning, the
system moves the accelerator pedal upward
to assist the driver to switch to the brake
pedal.
NOTE:
.The stop lights of the vehicle come on
when braking is performed by the DCA
system.
.When the brake operates, a noise may be
heard. This is not a malfunction.
Overriding the system:
The following driver’s operation overrides
the system operation.
.When the driver depresses the accelera-
tor pedal even further while the system is
moving the accelerator pedal upward,
the DCA system control of the accel-
erator pedal is canceled.
.When the driver’s foot is on the accel-
erator pedal, the brake control by the
system is not operated.
.When the driver’s foot is on the brake
pedal, neither the brake control nor the
alert by the system operates.
.When the Intelligent Cruise Control (ICC)
system is set, the DCA system will be
inactive.

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 depres-
sing the brake pedal to maintain a safe
vehicle distance if:
.The chime sounds.
.The vehicle ahead detection indicator
blinks.
.The driver assist system forward indica-
tor (orange) blinks.
The warning chime may not sound in some
cases when there is a short distance be-
tween 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 increasing
.When a vehicle cuts in near your vehicle
The driver assist system forward indicator
(orange) blinks and the warning chime will
not sound when your vehicle approaches
vehicles that are parked or moving slowly.
NOTE:
The approach warning chime may soundand the driver assist system forward in-
dicator (orange) may blink when the radar
sensor detects objects on the side of the
vehicle or on the side of the road. This may
cause the DCA system to decelerate or
accelerate the vehicle. The radar sensor
may detect these objects when the vehicle
is driven on winding 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).

To turn on the DCA system, push the
dynamic driver assistance switchon the
steering wheel after starting the engine. The
driver assistance switch indicator
in the
vehicle information display will appear. Push
the dynamic driver assistance switch
again
to turn off the DCA system. The driver
assistance switch indicator
will turn off.
The system will start to operate after the
vehicle speed is above approximately 3 MPH
(5 km/h).
The dynamic driver assistance switch
is
used for the DCA, Active Lane Control (if so
equipped), Lane Departure Prevention (LDP)
and Blind Spot Intervention
®(BSI) systems.
When the dynamic driver assistance switch
is pushed, Active Lane Control, LDP and
BSI systems will also turn on or off simulta-
neously. The DCA system can be individually
set to on or off on the lower display
. If the
system is set to off, the system will not turn
on even if the dynamic driver assistance
switch
is pushed to on. To set the system
to on or off on the display, see “How to
enable/disable the DCA system” (P.5-98).
When the conventional (fixed speed) cruise
control mode is operating, the DCA system
will not operate. (To use the DCA system,
turn the conventional (fixed speed) cruise

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.

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.

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.

pedestrian is detected, the FEB with pedes-
