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
cancelled.
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 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 warning chime will not sound when your
vehicle approaches vehicles that are parked
or moving slowly.
NOTE:
The approach warning chime may sound
and the system display 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).

For details about the conventional (fixed
speed) cruise control mode, see “Intelligent
Cruise Control (ICC)” (P.5-67).
When the engine is turned off, the system is
automatically turned off.

DCA SYSTEM DISPLAY AND IN-
DICATORS
The display is located between the speed-
ometer and tachometer.
1. DCA system switch indicator:
Indicates that the dynamic driver assis-
tance switch is ON.
2. Vehicle ahead detection indicator:
Indicates whether it detects a vehicle in
front of you.
3. DCA system warning light (orange):
The light comes on if there is a malfunc-
tion in the DCA system.

SYSTEM TEMPORARILY UNA-
VAILABLE
Condition A:
Under the following conditions, the DCA
system is automatically canceled. The chime
will sound and the DCA system switch
indicator will blink. The system will not be
able to be set.
.When the VDC system is off (To use the
DCA system, turn on the VDC, then push
the dynamic driver assistance switch.)
For details about the VDC system, see
“Vehicle Dynamic Control (VDC) system”
(P.5-123).

.When the VDC or ABS (including the
traction control system) operates
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode (To use the
DCA system, turn the INFINITI Drive
Mode Selector to a mode other than the
SNOW mode, then turn on the dynamic
driver assistance switch
.)
For details about the INFINITI Drive
Mode Selector, see “INFINITI Drive
Mode Selector” (P.5-20).
. When the radar signal is temporarily
interrupted
Action to take:
When the conditions listed above are no
longer present, turn the system off with the
dynamic driver assistance switch
. Turn the
DCA system back on to use the system.
JVS0482X
Condition B:
The chime sounds and the DCA system
warning light (orange) will come on and the
“FRONT RADAR OBSTRUCTION” warning
will appear.
. 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 can-
celed.
Action to take:
If the warning light comes on, park the
vehicle in a safe place, place the shift lever in
the P (Park) position and turn the engine off.
When the radar signal is temporarily inter-
rupted, clean the sensor area and restart the engine. If the “FRONT RADAR OBSTRUC-
TION” warning continues to be displayed,
have the DCA system checked. It is recom-
mended you visit an 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 DCA system warning light (orange)
and display the “FRONT RADAR OB-
STRUCTION” warning.
Action to take:
When the conditions listed above are no
longer present, turn the DCA system back on
to use the system.

SYSTEM MALFUNCTION
Condition:
When the DCA system is not operating
properly, the chime sounds and the system
warning light (“CRUISE” orange) will come
on.
Action to take:
If the warning light comes on, park the
vehicle in a safe place. 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 systemis located
behind the lower 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:

The FEB system uses a radar sensorlocated behind the lower grille of the front
bumper to measure the distance to the
vehicle ahead in the traveling lane.

FEB SYSTEM OPERATION
The FEB system operates at speeds above
approximately 3 MPH (5 km/h).
If a risk of a forward collision is detected, the
FEB system will provide the first warning to
the driver by blinking the vehicle ahead
detection indicator in the vehicle information
display and providing an audible warning. In
addition, the FEB system pushes the accel-
erator pedal up. If the driver releases the
accelerator pedal, then the system applies
partial braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB
system detects that there is still the possi-
bility of a forward collision, the system will
automatically increase the braking force.
If a forward collision is imminent and the
driver does not take action, the FEB system
issues the second visual (flashing) and
audible warning and automatically applies
harder braking.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB system.
Depending on vehicle speed and distance to
the vehicle 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 collisionshould one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the FEB 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 de-
tected ahead.
If the FEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the brakes
are released.
