DCA SYSTEM OPERATION
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious personal injury or
death.
∙ When the vehicle ahead detection indica- tor light is not illuminated, the system
will not control the vehicle or warn the
driver.
∙ Never place your foot under the brake pedal. Your foot may be caught when the
system controls the brake.
∙ Depending on the position of the accel- erator pedal, the system may not be able
to assist the driver to release the accel-
erator pedal appropriately.

The DCA system brakes and moves the ac-
celerator pedal upward according to the dis-
tance from and the relative speed of the ve-
hicle ahead to help assist the driver in
maintaining a following distance. The system
will decelerate as necessary and if the vehicle
ahead comes to a stop, the vehicle deceler-
ates to a standstill. However, the DCA sys-
tem can only apply up to approximately 40%
of the vehicle’s total braking power. If a ve-
hicle moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the DCA system cannot de-
celerate the vehicle quickly enough. If this
occurs, the DCA system will sound a warning
chime and blink the system display to notify
the driver to take necessary action. For addi-
tional information, refer to “Approach warn-
ing” in this section.The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelerator
pedal upward in the normal driving condition.
When a vehicle is detected ahead:
The vehicle ahead detection indicator comes
on.When vehicle approaches a vehicle ahead:
∙ If the driver’s foot is not on the accelera- tor pedal, the system activates the brakes
to decelerate smoothly as necessary. If
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill 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 re-
lease the accelerator pedal.
When brake operation by 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 sys-
tem 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.

∙ When the radar signal is temporarily in- terrupted
Action to take:
When the conditions listed above are no lon-
ger present, turn the system off with the
dynamic driver assistance switch (for models
without ProPILOT Assist) or the ProPILOT
Assist switch (for models with ProPILOT As-
sist) on the steering wheel. Turn the DCA
system back on to use the system. Condition B:
When the radar sensor area is covered with
dirt or is obstructed, making it impossible to
detect a vehicle ahead, the DCA system is
automatically canceled.
The chime sounds and the DCA system
warning light (orange) will come on and the
“Unavailable: Front Radar Blocked” warning
will appear.Action to take:
If the warning light comes on, park the vehicle
in a safe place, press the park button to place
the vehicle in the P (Park) position and turn
the engine off. When the radar signal is tem-
porarily interrupted, clean the sensor area
and restart the engine. If the “Unavailable:
Front Radar Blocked” warning continues to
be displayed, have the DCA system checked.
It is recommended you visit and INFINITI
retailer for this service.
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next to
long walls) the system may illuminate the sys-
tem warning light (orange) and display the
“Unavailable Front Radar Blocked” message.
Action to take:
When the above conditions no longer exist,
the DCA system will resume automatically.
Condition C:
When the DCA system is not operating prop-
erly, the chime sounds, the DCA system
warning light (orange) and the system “Mal-
function” warning message will appear in the
vehicle information display.

Action to take:
If the DCA system warning light (orange) and
the warning message appear, stop the ve-
hicle in a safe place and place the vehicle in
the P (Park) position. Turn the engine off,
restart the engine, and turn on the DCA sys-
tem 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 conditions,

1. Vehicle ahead detection indicator
2. FEB with Pedestrian Detection emer-gency warning indicator
3. FEB with Pedestrian Detection system warning light
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 operates 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 first provide a warning to the
driver by flashing the vehicle ahead detection
indicator and providing an audible alert. 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 force-
fully, but the FEB with Pedestrian Detection
system detects that there is still the possibility
of a forward collision, the system will auto-
matically increase the braking force.
LSD3573
Starting and driving5-151

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 with Pedestrian Detection 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 Pedestrian Detec-
tion system will provide a warning to the
driver by flashing the FEB with Pedestrian
Detection emergency warning indicator (red),
provides an audible alert and the system will
apply partial baking. 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 au-
tomatically 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 brake lights come on when any
braking is performed by the FEB with Pedes-
trian 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 if a
collision should be unavoidable. If the driver is
handling the steering wheel, accelerating 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 re-
main at a standstill for approximately 2 sec-
onds before the brakes are released.
