NOTE:
.In the case of several vehicles ap-
proaching in a row or from the opposite
direction, a chime may not be output to
the BCI system after the first vehicle
passes the sensors.
. When the parking sensor of the Around
View Monitor sounds a tone, the BCI
system does not chime a sound (single
beep).
If the detected vehicle approaches closer
and your vehicle is backing up toward the
detected vehicle, the system chimes a
sound (three times) and a red rectangular
frame
*Aappears on the center display.
The system applies the brake for a
moment. After the automatic brake appli-
cation, the driver must depress the brake
pedal to maintain brake pressure.
If the driver’s foot is on the accelerator
pedal, the system pushes the accelerator
pedal upward before applying the brake. If
you continue to press the accelerator
pedal, the system will not engage the
brake. A close object behind the vehicle:
If the sonar detects a close object behind
the vehicle when your vehicle is backing
up, the system chimes a sound (three
times) and a red rectangular frame

PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the distance sensor
*Adetects 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
throttle and applies the brakes (up to
25% of vehicle braking power) if neces- sary.
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.
. 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 congested areas.
. This system will not adapt automatically
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.
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 Intelligent Cruise Control
(ICC) system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Decelerate the vehicle speed by depres-
sing the brake pedal, depending on the
distance to the vehicle ahead and the
surrounding circumstances in order to
maintain a safe distance between vehi-
cles.
. 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.
. The system may not function properly

under the following conditions. To avoid
accidents, never use the ICC system
under the following conditions:
—On roads where the traffic is heavyor there are 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 the windshield wipers areoperating at high speed. The system
may cancel when the wipers are set
to the AUTO position.
—When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (the vehi-cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
—On repeated uphill and downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
—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 ICC system
when it is not recommended in this
section.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance. The
vehicle-to-vehicle distance control mode of
the Intelligent Cruise Control (ICC) system
may not be able to maintain the selected
distance between vehicles (following dis-
tance) or selected vehicle speed under
some circumstances.
The vehicle-to-vehicle distance control
mode uses a sensor
*Alocated on the
front of the vehicle to detect vehicles
Starting and driving5-59

5-60Starting and driving
traveling ahead. The sensor generally
detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if
the sensor cannot detect the reflector on
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 reflector of the vehicle ahead
is positioned high on the vehicle
(trailer, etc.)
. When the reflector on the vehicle ahead
is missing, damaged or covered
. When the reflector of the vehicle ahead
is covered with dirt, snow and road
spray
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When dense exhaust or other smoke
(black smoke) from vehicles reduces
the sensor’s visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
area of your vehicle
. When your vehicle is towing a trailer,
etc.
The ICC system is designed to automati- cally check the sensor’s operation within
the limitation of the system. When the
sensor is covered with dirt or obstructs, the
system will automatically be canceled. If
the sensor is covered with ice, a transpar-
ent 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.
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
decelerate the vehicle as necessary, and if
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill. How-
ever, the ICC system can only apply up to
25% of the vehicles 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 decele-
rates, the distance between vehicles may
become closer because the ICC system
cannot decelerate the vehicle quickly en-
ough. 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 falls below
approximately 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” later in this
section.
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 with-

in the limitations of the system. The
system will cancel once it judges that
the vehicle has come to 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 vehi-
cle 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.
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
winding, 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 traveling 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
maneuver 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.
SSD0254
When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the
speed to maintain the distance, selected
by the driver, from the vehicle ahead. If the
vehicle ahead changes lanes or exits the
freeway, the ICC system will accelerate and
maintain the speed up to the set speed.
Pay attention to the driving operation to
maintain control of the vehicle as it
accelerates to the set speed.
The vehicle may not maintain the set speed
on winding or hilly roads. If this occurs,
you will have to manually control the
vehicle speed.
