BCI SYSTEM OPERATION
When the shift lever is in the R (Reverse)
position and the vehicle speed is less than
approximately 5 MPH (8 km/h), the BCI
system operates.
If the radar detects a vehicle approaching
from the side or the sonar detects close
stationary objects behind the vehicle, the
system gives visual and audible warnings. If
the driver does not apply the brakes, the
system automatically applies the brake for a
moment when the vehicle is moving back-
wards. After the automatic brake applica-
tion, the driver must depress the brake pedal
to maintain brake pressure. If the driver’s
foot is on the accelerator pedal, the system

NOTE:
.In the case of several vehicles approach-
ing in a row (illustration 1) or from 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 chimes
(once) indicating an approaching vehi-
cle. If the sonar system detects an object
behind the vehicle and the BCI system
detects an approaching vehicle at the
same time, the following indications 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.

If an approaching vehicle or object behind
the vehicle is detected when your vehicle is
backing up, a red frame
will appear on the
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.

WARNING
Failure to follow the warnings and
instructions for proper use of the ICC
system could result in serious injury or
death.
.ICC is not a collision avoidance or
warning device. For highway use only
and it is not intended for congested
areas or city driving. Failure to apply
the brakes could result in an accident.
. Always observe posted speed limits
and do not set the speed over them.
. Always drive carefully and atten-
tively when using either cruise con-
trol mode. Read and understand the
Owner’s Manual thoroughly before
using the cruise control. 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
cruise control except in appropriate
road and traffic conditions.
. In the conventional (fixed speed)
cruise control mode, a warning chime
will not sound to warn you if you are
too close to the vehicle ahead. Pay
special attention to the distance
between your vehicle and the vehicle ahead of you or a collision could
occur.
The ICC system maintains a selected dis-
tance from the vehicle in front of you within
the speed range of 0 to 90 MPH (0 to 144
km/h) up to the set speed. The set speed can
be selected by the driver between 20 to 90
MPH (32 to 144 km/h).
The vehicle travels at a set speed when the
road ahead is clear.
The ICC system can be set to one of two
cruise control modes.
. Vehicle-to-vehicle distance control
mode:
For maintaining a selected distance
between your vehicle and the vehicle in
front of you up to the preset speed.
. Conventional (fixed speed) cruise control
mode:
For cruising at a preset speed.

INTELLIGENT CRUISE CONTROL
(ICC) (if so equipped)

5-70Starting and driving
JVS0462X
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.5-78). 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.

The driver sets the desired vehicle speed
based on the road conditions. The ICC
system maintains the set vehicle speed,
similar to standard cruise control, as long
as no vehicle is detected in the lane ahead.
The ICC system displays the set speed.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by
controlling the throttle and applying the
brakes to match the speed of a slower
vehicle ahead. The system then controls the vehicle speed based on the speed of the
vehicle ahead to maintain the driver selected
distance.
NOTE:
.
The stop lights of the vehicle come on
when braking is performed by the ICC
system.
. When the brake operates, a noise may be
heard. This is not a malfunction.
When a vehicle ahead is detected, the
vehicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance. Vehicle ahead not detected:
When a vehicle is no longer detected ahead,
the ICC system gradually accelerates your
vehicle to resume the previously set vehicle
speed. The ICC system then maintains the
set speed.
When a vehicle is no longer detected the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system
controls the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the
system will be canceled.

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
