NOTE:
.In the case of several vehicles approach-
ing in a row (Illustration 1) or in the
opposite direction (Illustration 2), a
chime may not be sounded by the BCI
system after the first vehicle passes the
sensors.
. The sonar system chime indicating there
is an object behind the vehicle has a
higher priority than the BCI chime
(single beep) indicating an approaching
vehicle. If the sonar system detects an
object behind the vehicle and the BCI
system detects an approaching vehicle
at the same time, the following indica-
tions are provided:
— The sonar system chime sounds
— The side indicator light on the side of
the approaching vehicle flashes, and
— A yellow rectangular frame appears
in the display.

Upper display
If an approaching vehicle or object behind
the vehicle is detected when your vehicle is
backing up, a red frame
will appear on the
upper display and the system will chime
three times. Then, the brakes will be applied
momentarily. After the automatic brake
application, the driver must depress the
brake pedal to maintain brake pressure.
If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward before the braking is applied.
However, if you continue to accelerate, the
system will not engage the brakes.
The BCI system does not operate if the
object is very close to the bumper.

BCI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BCI system. Failure to operatethe vehicle in accordance with these
system limitations could result in serious
injury or death.
.
Always check your surroundings and
turn to check what is behind you
before backing up. .
The radar sensors detect approach-
ing (moving) vehicles. The radar sen-
sors cannot detect every object such
as:
— Pedestrians, bicycles, animals or child operated toy vehicles
— A vehicle that is passing at speeds greater than approximately 15
MPH (24 km/h)
. The radar sensors may not detect
approaching vehicles in certain situa-
tions:
— Illustration a. When a vehicle parked next to you obstructs the
beam of the radar sensor.
— Illustration b. When the vehicle is parked in an angled parking space.
— Illustration c. When the vehicle is parked on inclined ground.
— Illustration d. When an approach- ing vehicle turns into your vehi-
cle’s parking lot aisle.
— Illustration e. When the angle formed by your vehicle and ap-
proaching vehicle is small.
. The following conditions may reduce
the ability of the radar sensors to
detect other vehicles:

— Severe weather
— Road spray
— Ice/frost/dirt build up on thevehicle
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar
sensors to detect other vehicles.
. The sonar sensors detect stationary
objects behind the vehicle. The sonar
sensor may not detect:
— Small or moving objects
— Wedge-shaped objects
— Object close to the bumper (less than approximately 1 ft (30 cm))
— Thin objects such as rope, wire and chain, etc.
. The brake engagement by the BCI
system is not as effective on a slope
as it is on flat ground. When on a
steep slope the system may not
function properly.
. Do not use the BCI system under the
following conditions because the sys-
tem may not function properly. — When driving with a tire that is
not within normal tire conditions
(for example, tire wear, low tire
pressure, installation of spare tire,
tire chains, non-standard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.

The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the radar sensor
detects a slower
moving vehicle ahead, the system will reduce
the vehicle speed so that your vehicle
follows the vehicle in front at the selected
distance.
The system automatically controls the throt-
tle and applies the brakes (up to approxi-
mately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.
Vehicle-to-vehicle distance control
mode operation
The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match the
slower vehicle ahead; the system will de-
celerate the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to approximately
40% of the vehicle’s total braking power.
This system should only be used when traffic
conditions allow vehicle speeds to remain
fairly constant or when vehicle speeds
change gradually. 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 ICC system cannot
decelerate the vehicle quickly enough. If this
occurs, the ICC system will sound a warning
chime and blink the system display to notify
the driver to take necessary action.
The system will cancel and a warning chime
will sound if the speed is below approxi-
mately 15 MPH (24 km/h) and a vehicle is
not detected ahead. The system will also
disengage when the vehicle goes above the
maximum set speed.
See “Approach warning” (P.5-81). The following items are controlled in the
vehicle-to-vehicle distance control mode:
.
When there are no vehicles traveling
ahead, the vehicle-to-vehicle distance
control mode maintains the speed set
by the driver. The set speed range is
between approximately 20 and 90 MPH
(32 and 144 km/h).
. When there is a vehicle traveling ahead,
the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by driver, from the
vehicle ahead. The adjusting speed range
is up to the set speed. 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 a standstill with
a warning chime.
. When the vehicle traveling ahead has
moved out from its lane of travel, the
vehicle-to-vehicle distance control mode
accelerates and maintains vehicle speed
up to the set speed.
The ICC 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 when approaching toll gates or traffic
congestion.

JVS0250M
.The distance to the vehicle ahead will
change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
. If the engine is stopped, the set distance
becomes “long”. (Each time the engine 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 indicator 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
Starting and driving5-81

5-82Starting and driving
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
position or Manual 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
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:
