and the side indicator light flashes.

Illustration 6 – Overtaking another vehicle
Illustration 6: If the BSI system is on and your
vehicle approaches a lane marker while
another vehicle is in the detection zone, the
system chimes (three times) and the side
indicator light flashes. Then, the BSI system
slightly applies the brakes on the appropriate
side to help return the vehicle back to the
center of the driving lane.
NOTE:
. When overtaking several vehicles in a
row, the vehicles after the first vehicle
may not be detected if they are travel-
ing close together.
. The radar sensors may not detect slower
moving vehicles if they are passed quickly.
. If the driver activates the turn signal
before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the other
vehicle is detected.

from either side.
NOTE:
The radar sensors may not detect a vehicle
which is traveling at about the same speed
as your vehicle when it enters the detection
zone.

Illustration 10: The BSI system will not
operate if your vehicle is on a lane marker
when another vehicle enters the detection
zone. In this case only the BSW system
operates.
NOTE:
. The radar sensors may not detect a
vehicle which is traveling at about the
same speed as your vehicle when it
enters the detection zone.
. If the driver activates the turn signal
before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the other
vehicle is detected. .
BSI braking will not operate or will stop
operating and only a warning chime will
sound under the following conditions.
— When the brake pedal is depressed.
— When the vehicle is accelerated dur-
ing BSI system operation.
— When steering quickly
— When the ICC, DCA, PFCW or FEB
warnings sound.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.

Operation is subject to the following two
conditions:
1. This device may not cause harmfulinterference.
2. This device must accept any interference received, including interference that may
cause undesired operation.
Frequency of operation: 24.05GHz —
24.25GHz
Field Strength: Not greater than 2.5V/m
peak (0.25V/m average) at a distance of 3 m
The manufacturer is not responsible for any
radio or TV interference caused by un-
authorized modifications to this equipment.
Such modifications could void the user’s
authority to operate the equipment.
WARNING
Failure to follow the warnings and
instructions for proper use of the BCI
system could result in serious injury or
death.
. The BCI system is not a replacement
for proper driving procedure, is not
designed to prevent contact with
vehicles or objects and does not
provide full brake power. When back-
ing out of parking spaces, always use
the inside and rear mirrors and turn
and look in the direction you will
move. Never rely solely on the BCI
system.
. There is a limitation to the detection
capability of the radar or the sonar.
Using the BCI system under some
road, ground, traffic or weather con-
ditions could lead to improper system
operation. Always rely on your own
operation to avoid accidents.
The BCI system can help alert the driver of
an approaching vehicle or objects behind the
vehicle when the driver is backing out of a
parking space.
JVS0735X
The BCI system uses radar sensorsinstalled on both sides near the rear bumper
to detect an approaching vehicle and sonar
sensors
to detect objects in the rear.

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

pushes the accelerator upward before ap-
plying the brake. If you continue to accel-
erate, the system will not engage the brake.

BCI ON indicatorWhen the shift lever is placed in the R
(Reverse) position, the indicator on the BCI
system key
illuminates on the display and
the BCI ON indicator appears in the vehicle
information display.

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.
JVS0307X
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.

— 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.

SYSTEM TEMPORARILY UNA-
VAILABLE
Under the following conditions, a chime will
sound and “BCI NOT AVAILABLE” warning
will appear in the vehicle information display
, and the BCI system will be turned off
automatically.
. If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F (40°C)).
. When side radar blockage is detected.
Turn off the BCI system and turn it on again
when the above conditions no longer exist.
