Under the following conditions, the Dis-
tance Control Assist system will not oper-
ate and the Distance Control Assist (DCA)
system switch indicator light will blink:
.When the SNOW mode switch is ON (To
use the DCA system, turn off the SNOW
mode switch, then push the dynamic
driver assistance switch.)
For details about the SNOW mode
switch, see “SNOW mode switch” in
the “2. Instruments and controls” sec-
tion.
. 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) sys-
tem”
later in this section.
. When ABS or VDC (including the trac-
tion control system) is operating
. When driving into a strong light (i.e.,
sunlight)
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
control mode off, then push the dynamic
driver assistance switch.)
For details about the Conventional (fixed
speed) cruise control mode, see “Intelli-
gent Cruise Control (ICC) system (FULL
SPEED RANGE)” earlier in this section.
When the engine is turned off, the system
is automatically turned off.

System operationGUID-C6A46949-EB7A-4EF4-863E-108F23B571A5
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:

5-68Starting and driving
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)).

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).

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

5-72Starting and driving
SSD1156
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 indicator light
*1on the
switch will illuminate when the system
turns on.
PRECAUTIONS ON FCW SYSTEMGUID-E6CD8DCD-7100-4AD2-9117-4702A2FEFF68
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 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.

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.
