NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects some reflectors
*A
which are fitted on vehicles in other lanes
or on the side of the road. This may cause
the ICC system to decelerate or accelerate
the vehicle. The ICC sensor may detect
these reflectors when the vehicle is driven
on winding roads, hilly roads or when
entering or exiting a curve. The ICC 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).
Automatic cancellation
A chime sounds under the following con-
ditions and the control is automatically
canceled.
.
When the vehicle ahead is not detected
and your vehicle is traveling below the
speed of 15 MPH (24 km/h)
. When the system judges the vehicle is
at standstill
. When the shift lever is not in the D, DS
or Manual mode
. When the windshield wipers are operat-
ing at low (LO) or high speed (HI). If the
vehicle is equipped with a rain sensing
auto-wiper, the system may cancel
when the wipers are set to intermittent
(INT).
. When the parking brake is applied
. When the SNOW mode switch is turned
ON
. When the VDC system is turned off
. When ABS or VDC (including the trac-
tion control system) operates .
When driving into a strong light (for
example, sunlight)
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor
. When a wheel slips

Sensor maintenance
The sensor for the ICC system*Ais located
below the front bumper.
To keep the ICC system operating properly,
be sure to observe the following:
. Always keep the sensor clean. Wipe
with a soft cloth carefully so as not to
damage the sensor.
. Do not strike or damage the areas
around the sensor. Do not touch or
remove the screw located on the
sensor. Doing so could cause failure
or malfunction. If the sensor is da-
maged due to an accident, contact an

INFINITI retailer.
. Do not attach a sticker (including
transparent material) or install an
accessory near the sensor. This could
cause failure or malfunction.
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 thatvaries 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.

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

PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
The 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 depresses the brake pedal and helps
improve brake response by reducing pedal
free play.
For more details, see
“Brake assist”(P.5-
84).

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 Distance Control Assist
system. Read and understand the Own-
er’s Manual thoroughly 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 Distance Control Assist
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.
SSD0701
PRECAUTIONS ON DISTANCE CON-
TROL ASSIST 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 distance 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
25% of vehicle braking power) if neces-
sary.
