Warning
When the system is not operating properly,
the chime sounds and the color of the
cruise indicator will change to orange.
Action to take:
If the color of the cruise indicator changes
to orange, park the vehicle in a safe place.
Turn the hybrid system off, restart the
hybrid system, resume driving and then
perform the setting again.
If it is not possible to set 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.

The Distance Control Assist (DCA) system
brakes and moves the accelerator pedal
upward according to the distance from and
the relative speed of the vehicle ahead to
help assist the driver to maintain a
following distance.
WARNING
.Always drive carefully and attentively
when using the DCA system. Read and
understand the Owner’s Manual thor-
oughly before using the DCA system. To
avoid serious injury or death, do not rely
on the system to prevent accidents or to
control the vehicle’s speed in emergency
situations. Do not use the DCA system
except in appropriate road and traffic
conditions.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill with
a warning chime. To prevent the vehicle
from moving, the driver must depress
the brake pedal.
. The DCA system will not apply brake
control while the driver’s foot is on the accelerator pedal.
JVS0235X
PRECAUTIONS ON DCA SYSTEM
The system is intended to assist the driver
to keep a following distance from the
vehicle ahead traveling in the same lane
and direction.
If the radar sensor
*Adetects a slower
moving vehicle ahead, the system will
reduce the vehicle speed to help assist
the driver to maintain a following distance.
The system automatically controls the
throttle and applies the brakes (up to
approximately 40% of vehicle braking
power) if necessary.
The detection range of the sensor is
Starting and driving5-79
DISTANCE CONTROL ASSIST (DCA) SYSTEM
(if so equipped)

5-80Starting and driving
approximately 650 ft (200 m) ahead.
WARNING
.This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. This system will not adapt automatically
to road conditions. Do not use the
system on roads with sharp curves, or
on icy roads, in heavy rain or in fog.
The distance sensor will not detect the
following objects:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
WARNING
. As there is a performance limit to the
distance control function, never rely solely on the DCA system. This system
does not correct careless, inattentive or
absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by
depressing the brake pedal, depending
on the distance to the vehicle ahead and
the surrounding circumstances in order
to maintain a safe distance between
vehicles.
. The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the DCA system under the following
conditions:
—On roads with sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—During bad weather (rain, fog, snow,etc.)
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (frequentbraking may result in overheating
the brakes)
—On repeated uphill and downhillroads .
In some road or traffic conditions, a
vehicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.

JVS0235X
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.
