How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
Each time the DISTANCE switch
is
pushed, the set distance will change to long,
middle, short and back to long again in that
sequence.JVS0082M
. The distance to the vehicle ahead will
change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
. If the hybrid system is stopped, the set
distance becomes “long”. (Each time the
hybrid system is started, the initial
setting becomes “long”.)

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
ICC system display. Decelerate by depres-
sing the brake pedal to maintain a safe
vehicle distance if:
.The chime sounds.
. The vehicle ahead detection and set
distance indicator blink.
The warning chime may not sound in some
cases when there is a short distance be-
tween vehicles. Some examples are:
. 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 vehicles
is increasing
. When a vehicle cuts in near your vehicle
The warning chime will not sound when:
. Your vehicle approaches other vehicles
that are parked or moving slowly.
. The accelerator pedal is depressed, over-
riding the system. NOTE:
The approach warning chime may sound
and the system display may blink when the
radar sensor detects objects on the side of
the vehicle or on the side of the road. This
may cause the ICC 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
A chime sounds under the following condi-
tions and the control is automatically can-
celed.
.
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 (Drive)
or manual shift mode .
When the parking brake is applied
. When the INFINITI Drive Mode Selector
is turned to the SNOW mode
. When the VDC system is turned off
. When ABS or VDC (including the traction
control system) operates
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor
. When a wheel slips
. When the radar signal is temporarily
interrupted
Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The system is primarily intended for
use on straight, dry, open roads with
light traffic. It is not advisable to use
the system in city traffic or con-
gested areas.
. This system will not adapt automati-
cally to road conditions. This system
Starting and driving5-77

5-78Starting and driving
should be used in evenly flowing
traffic. Do not use the system on
roads with sharp curves, or on icy
roads, in heavy rain or in fog.
. As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absent-minded driving, or over-
come 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 surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
. 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 and sound a warning chime.
To prevent the vehicle from moving,
the driver must depress the brake
pedal.
. Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain the selected distance between vehi-
cles (following distance) or selected
vehicle speed under some circum-
stances.
. The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the ICC system
under the following conditions:
— On roads where the traffic is heavy or there are 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 to the system sensor
— On steep downhill roads (the vehicle may go beyond the set
vehicle speed and frequent brak-
ing may result in overheating the
brakes)
— On repeated uphill and downhill roads
— When traffic conditions make it difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration .
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 accel-
erator pedal. Always stay alert and
avoid using the ICC system when it is
not recommended in this section.
The radar sensor will not detect the follow-
ing 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
The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system may
not maintain the selected distance.
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 trunk of
your vehicle

The ICC system is designed to automatically
check the sensor’s operation within the
limitation of the system. When the sensor
is covered with dirt or is obstructed, the
system will automatically be canceled. If the
sensor is covered with ice, a transparent or
translucent vinyl bag, etc., the ICC system
may not detect them. In these instances, the
vehicle-to-vehicle distance control mode
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead. Be sure to check
and clean the sensor regularly.
SSD0252
The detection zone of the ICC sensor is
limited. A vehicle ahead must be in the
detection zone for the vehicle-to-vehicle
distance detection mode to maintain the
selected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are
traveling offset from the centerline of the
lane. A vehicle that is entering the lane ahead
may not be detected until the vehicle has
completely moved into the lane.If this
occurs, the ICC system may warn you by
blinking the system indicator and sounding
the chime. The driver may have to manually control the proper distance away from
vehicle traveling ahead.

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the ICC sensor
may detect vehicles in a different lane, or
may temporarily not detect a vehicle travel-
ing ahead. This may cause the ICC system to
decelerate or accelerate the vehicle.
The detection of vehicles may also be
affected by vehicle operation (steering man-
euver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the ICC
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.
