2. Push and hold the COAST/SET switch.Release the switch when the vehicle
slows down to the desired speed.
3. Push, then quickly release the COAST/ SET switch. Each time you do this, the
set speed will decrease by about 1 MPH
(1.6 km/h).
To resume the preset speed, push and
release the ACCELERATE/RESUME switch.
The vehicle will resume the last set
cruising speed when the vehicle speed is
over 25 MPH (40 km/h).
Automatic cancellation
A chime sounds under the following con-
ditions and the control is automatically
canceled.
. When the vehicle slows down more
than 8 MPH (13 km/h) below the set
speed
. When the shift lever is shifted to the N
(Neutral) position
. When the parking brake is applied
. When the VDC (including the traction
control system) operates.
. When a wheel slips

Warning light
When the system is not operating properly,
the chime sounds and the system warning
light (orange) will come on.
Action to take:
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, 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.
PREVIEW FUNCTION (for Intelligent
Cruise Control (ICC) system
equipped model)
The Intelligent Cruise Control (ICC) system
with the preview function identifies the
need to apply emergency braking by
sensing the vehicle ahead in the same
lane and the distance to the vehicle ahead
and relative speed from it, it applies the
brake pre-pressure before the driver de-
presses the brake pedal and helps improve
brake response by reducing pedal free
play.
For more details, see
“Brake assist”later in
this section.

The detection range of the sensor is
approximately 390 ft (120 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 Distance Control Assist
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. The system may not function properly
under the following conditions. To avoid
accidents, never use the Distance Con-
trol Assist system under the following
conditions:
—On roads with sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—On off-road surfaces such as onsand or rock, etc.
—During bad weather (rain, fog, snow,etc.)
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (frequent
braking may result in overheating
the brakes)
—On repeated uphill and downhillroads
—When towing a trailer or othervehicle
. 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.

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.

Operating Distance Control Assist
(DCA) system
The DCA system turns on when the
dynamic driver assistance switch on the
steering wheel is pushed when“Distance
Control Assist” is enabled in the settings
menu in the center display. The DCA
system switch indicator on the dot matrix
liquid crystal display will illuminate.
The system will start to operate after the
vehicle speed becomes above approxi-
mately 3 MPH (5 km/h).
WARNING
When the DCA system is not necessary, be
sure to turn off the dynamic driver assis-
tance switch. Using the system when it is
not necessary may result in an accident.

tance Control Assist system will not oper-
ate and the Distance Control Assist (DCA)

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
when braking is performed by the DCA
system.
When the brake operates, a noise may be
heard and/or vibration may be felt. This is
not a malfunction.

example, sunlight)
Action to take:
When the conditions listed above are no
longer present, turn the system off with the
dynamic driver assistance switch. Turn the
DCA system back on to use the system.

Condition B:
When the sensor window is dirty, making it
impossible to detect a vehicle ahead, the
DCA system is automatically canceled.
The chime sounds and the system warning
light (orange) will come on and the “CLEAN

Action to take:
If the warning light comes on, park the
vehicle in a safe place, turn the engine off.
Clean the sensor window with a soft cloth
and then perform the settings again.
