INFINITI retailer.
Sensor maintenance
How to handle the sensor:
The sensor for the DCA system is common
with Intelligent Cruise Control and is
located below the front bumper.
To handle the sensor, see“Intelligent
Cruise Control (ICC) system” earlier in this
section. The Forward Collision Warning (FCW) sys-
tem will warn the driver by the vehicle
ahead detection indicator light and chime
when your vehicle is getting close to the
vehicle ahead in the traveling lane.
The FCW system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) and above.

FORWARD COLLISION WARNING (FCW)
SYSTEM (if so equipped)

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.
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(i.e., 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 vehicle
ahead are missing, damaged or
covered.
—When the reflectors of the vehicleahead are covered with dirt, snow or
road spray.
—When visibility is low (such as rain,fog, snow, etc.).
—When snow or road spray from
traveling vehicles is splashed.
—When dense exhaust or other smoke (black smoke) from vehicles reduces
the visibility of the sensor.
—When excessively heavy baggage is
loaded 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 (i.e.,
being very close to another vehicle,
signboard, etc.)
. 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 (i.e., 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
SSD1000
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 ”later in this
section.

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.
