CONVENTIONAL (fixed speed)
CRUISE CONTROL MODE
This mode allows driving at a speed
between 25 to 90 MPH (40 to 144 km/h)
without keeping your foot on the accel-
erator pedal.
WARNING
. In the conventional (fixed speed) cruise
control mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the pre-
sence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected.
. Pay special attention to the distance
between your vehicle and the vehicle
ahead of you or a collision could occur.
. Always confirm the setting in the In-
telligent Cruise Control system display.

.Do not use the conventional (fixed
speed) cruise control mode when driving
under the following conditions:
—when it is not possible to keep the
vehicle at a set speed
—in heavy traffic or in traffic that
varies in speed
—on winding or hilly roads
—on slippery roads (rain, snow, ice,etc.)
—in very windy areas
. Doing so could cause a loss of vehicle
control and result in an accident.JVS0222X

DCA SYSTEM OPERATION
Always pay attention to the operation of
the vehicle and be ready to manually
decelerate to maintain the proper following
distance. The Distance Control Assist (DCA)
system may not be able to decelerate the
vehicle under some circumstances.
The DCA system uses a sensor
*Alocated
behind the lower grille of the front bumper
to detect vehicles traveling ahead.
The following are some conditions in which
the sensor cannot detect the signals:
. When the snow or road spray from
traveling vehicles reduces the sensor’s visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
room of your vehicle
The DCA system is designed to automati-
cally check the sensor’s operation. When
the sensor area of the front bumper is
covered with dirt or is obstructed, the
system will automatically be canceled. If
the sensor area 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 area
regularly.
The DCA system is designed to help assist
the driver to maintain a following distance
from the vehicle ahead. The system will
decelerate as necessary and if the vehicle
ahead comes to a stop, the vehicle
decelerates to a standstill. However, the
DCA system can only apply up to approxi-
mately 40% of the vehicles total braking
power. If a vehicle 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 decelerate 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.
See
“Approach warning” (P.5-86).
This system only brakes and moves the
accelerator pedal upward to help assist the
driver to maintain a following distance
from the vehicle ahead. Acceleration
should be operated by the driver.
The DCA system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead.
Starting and driving5-81

SSD0253
When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
sensor may detect vehicles in a different
lane, or may temporarily not detect a
vehicle traveling ahead. This may cause
the system to work inappropriately.
The detection of vehicles may also be
affected by vehicle operation (steering
maneuver or traveling position in the lane,
etc.) or vehicle condition.If this occurs, the
system may warn you by blinking the
system indicator and sounding the chime
unexpectedly. You will have to manually
control the proper distance away from the vehicle traveling ahead.

System operation
WARNING
The Distance Control Assist (DCA) system
automatically decelerates your vehicle to
help assist the driver to maintain a follow-
ing distance from the vehicle ahead. Manu- ally 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.
Starting and driving5-85

5-86Starting and driving
When a vehicle ahead is detected:
The vehicle ahead detection indicator
comes on.
When the 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
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 is not illuminated, system will
not control or warn the driver.
. 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 (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
depressing the brake pedal to maintain a
safe vehicle distance if:
. The chime sounds.
. The vehicle ahead detection indicator
blinks.

.The driver assist system forward indi-
cator (orange) blinks.
. 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 driver assist system forward indicator
(orange) blinks and 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 driver assist system forward
indicator (orange) may blink when the
radar sensor detects objects on the side of
the vehicle
*Aor on the side of the road
*A. 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).
Automatic cancellation
Condition A:
Under the following conditions, the Dis-
tance Control Assist (DCA) system is
automatically canceled. The chime will
sound and the
“currently unavailable”
warning message will appear in the vehicle
information display. The system will not be
able to be set.
. When the VDC system is turned off
. When the VDC or ABS (including the
traction control system) operates
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode
. When the radar signal is temporarily
interrupted.
Action to take:
When the conditions listed above are no
longer present, turn the DCA system back
on to use the system.
Condition B:
When the radar sensor area of the front
bumper is covered with dirt or is ob-
Starting and driving5-87

structed, making it impossible to detect a
vehicle ahead, the DCA system is auto-
matically canceled.
The chime will sound, the driver assist
system forward indicator (orange) and the
“front radar obstruction”warning message
will appear in the vehicle information
display.
Action to take:
If the driver assist system forward indicator
(orange) and the warning message appear,
park the vehicle in a safe place, turn the
hybrid system off. When the radar signal is
temporarily interrupted, clean the sensor
area of the front bumper and restart the
hybrid system. If the warning message
continues to be displayed, have the DCA
system checked by an INFINITI retailer.
Condition C:
When the DCA system is not operating
properly, the chime sounds, the driver
assist system forward indicator (orange)
and the system “malfunction” warning
message will appear in the vehicle infor-
mation display. Action to take:
If the driver assist system forward indicator
(orange) and the warning message appear,
park the vehicle in a safe place. Turn the
hybrid system off, restart the hybrid
system, 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
conditions, have the vehicle checked at
an INFINITI retailer.
