System operation
WARNING
The Distance Control Assist system auto-
matically decelerates your vehicle to help
assist the driver to maintain a following
distance from the vehicle ahead. Manually
brake when deceleration is required to
maintain a safe distance upon sudden
braking by the vehicle ahead or when a vehicle suddenly appears in front of you.
Always stay alert when using the DCA
system.
The Distance Control Assist (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
accelerator 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 accelera-
tor pedal upward to assist the driver to
release the accelerator pedal.
When brake operation by driver is re-
quired:
The system alerts the driver by a warning
chime and blinking the vehicle ahead
detection 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.
The stoplights of the vehicle come on and
the brake pedal depresses when braking is
performed by the DCA system.
When the brake operates, a noise may be
heard. This is not a malfunction.

WARNING
.When the vehicle ahead detection in-
dicator light is not illuminated, system
will not control 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
accelerator pedal appropriately.
. If the vehicle ahead comes to a stand-
still, the vehicle decelerates to a stand-
still within the limitations of the system.
The system will release brake control
with a warning chime once it judges the
vehicle is at a standstill. To prevent the
vehicle from moving, the driver must
depress the brake pedal. (The system
will resume control automatically once
the system reaches 3 MPH (5 km/h)).
Overriding the system:
The following driver’s operation overrides
the system operation. .
When the driver depresses the accel-
erator pedal even further while the
system is moving the accelerator pedal
upward, the DCA system control of the
accelerator 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
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
depressing 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
between 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 vehi-
cles 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.

SSD0284A
NOTE:
The approach warning chime may sound
and the system display may blink when
the sensor detects some reflectors
*Awhich are fitted on vehicles in other lanes
or on the side of the road. This may cause
the DCA system to operate inappropriately.
The sensor may detect these reflectors
when the vehicle is driven on winding
roads, hilly roads or when entering or
exiting a curve. The sensor may also detect
reflectors on narrow roads or in road
construction zones. 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).

Warning systems switch
The FCW system uses the distance sensor
*Alocated below the front bumper to
measure the distance to the vehicle ahead.
When the system judges that your vehicle
is getting close to the vehicle ahead in the
travel lane, the vehicle ahead detection
indicator light on the instrument panel
blinks and a warning chime sounds.
The FCW system will be turned on/off by
pushing the warning systems switch. The
warning systems ON indicator light

the switch will illuminate when the system
turns on.
PRECAUTIONS ON FCW SYSTEM
WARNING
. The FCW system is intended to warn you
before a collision but will not avoid a
collision. It is the driver’s responsibility
to stay alert, drive safely and be in
control of the vehicle at all times.
. As there is a performance limit, the
system may not provide a warning in
certain conditions.
. The system will not detect the following
objects:
—Pedestrians, animals or obstacles in
the roadway
—Oncoming vehicles in the same lane
. The system will not detect another
vehicle under the following conditions:
—When the sensor gets dirty and it is
impossible to detect the distance
from the vehicle ahead.
—When driving into a strong light (forexample, sunlight)
. The sensor generally detects the signals
returned from the reflectors on a vehicle ahead. Therefore, the system may not
function properly under the following
conditions:
—When the reflectors of the vehicle
ahead are positioned high or close to
each other (including a small vehicle
such as motorcycles).
—When the sensor gets dirty or it isimpossible to detect the distance
from the vehicle ahead.
—When the reflectors on the vehicleahead are missing, damaged or
covered.
—When the reflectors of the vehicle
ahead are covered with dirt, snow or
road spray.
—When visibility is low (such as rain,fog, snow, etc.).
—When snow or road spray fromtraveling vehicles is splashed.
—When dense exhaust or other smoke (black smoke) from vehicles reduces
the visibility of the sensor.
—When excessively heavy baggage isloaded in the rear seat or the
luggage room of your vehicle.

—When abruptly accelerating or de-celerating.
—On a steep downhill slope or onroads with sharp curves.
—When there is a highly reflectiveobject near the vehicle ahead (for
example, being very close to another
vehicle, signboard, etc.)
—When you are towing a trailer.
. Depending on certain road conditions
(curved or beginning of a curve), vehicle
conditions (steering position or vehicle
position), or the preceding vehicle’ s
conditions (position in lane, etc.), the
system may not function properly. The
system may detect highly reflective
objects such as reflectors, signs, white
markers, and other stationary objects on
the road or near the traveling lane and
provide unnecessary warning.
. The system may not function in offset
conditions.
. The system may not function when the
distance to the vehicle ahead is extre-
mely close.
. The system is designed to automatically
check the sensor’s functionality. If the sensor is covered with ice, a transparent
or translucent plastic bag, etc., the
system may not detect them. In these
instances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor regularly.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
. A sudden appearance of a vehicle in
front (for example, it abruptly cuts in)
may not be detected and the system may
not warn the driver soon enough.
. The system will be cancelled automati-
cally with a beep sound and the IBA OFF
indicator light will illuminate under the
following conditions:
—When the sensor window is dirty
—When the system malfunctions
SSD0748
If the IBA OFF indicator light*Ailluminates
with a beep sound, pull off the road to a
safe location, stop the vehicle and turn the
engine off. Check to see if the sensor
window is dirty. If the sensor window is
dirty, clean it with a soft cloth and restart
the engine. If the sensor window is not
dirty, restart the engine. If the IBA OFF
indicator light continues to illuminate even
if the IBA system is turned on with the IBA
OFF switch
*B, have the system checked
by an INFINITI retailer.
To turn on the IBA system, see “Intelligent
Brake Assist (IBA) system” (P.5-70).

When the warning systems switch is
pushed, the LDW system will also turn on
or off simultaneously. See
“Lane Departure
Warning (LDW) system/Lane Departure
Prevention (LDP) system” (P.5-21).
In the manual setting mode, you need to
push the warning systems switch to turn
on the system after the ignition switch is
pushed to the ON position.
The setting mode can be changed using
the warning systems switch. To change the
setting mode, push and hold the warning
systems switch for more than 4 seconds
when the warning systems ON indicator is
off. When the mode is changed, a chime
sounds and the lane departure warning
light (orange) flashes.
For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system (FULL
SPEED RANGE)” (P.5-32). The Intelligent Brake Assist (IBA) system
warns the driver by a warning light and
chime when there is a risk of a collision
with the vehicle ahead in the traveling lane
and the driver must take avoidance action
immediately. The system helps reduce the
rear-end collision speed by applying the
brakes when the system judges that the
collision cannot be prevented.
The IBA system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) and above, and
when your vehicle is driven at speeds
approximately 10 MPH (15 km/h) faster
than the vehicle ahead.
