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.

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.
SYSTEM TEMPORARILY UNA-
VAILABLE
. If the following messages appear in the
vehicle information display, a chime will
sound and the BSI system will be turned
off automatically.
— “Not available: Poor Road Condi- tions”:
When the VDC system (except TCS
function) or ABS operates.
— “Currently unavailable”: When the VDC system is turned off.
When the SNOW mode is selected.
When the 4WD shift switch is in the
4H or 4L position. (4WD models) Action to take:
Turn off the BSI system and turn it on again
when the above conditions no longer exist.
.
If the following messages appear in the
vehicle information display, a chime will
sound and the BSI system will be turned
off automatically. The BSI system is not
available until the conditions no longer
exist.
— “Not available: High Camera Temp”:
When the camera detects that the
interior temperature is high (over
approximately 104°F (40°C)).
— “Unavailable: Side Radar Obstruc- tion”:
When radar blockage is detected.
The radar sensors may be blocked by
temporary ambient conditions such as
splashing water, mist or fog. The blocked
condition may also be caused by objects
such as ice, frost or dirt obstructing the radar
sensors.
Action to take:
When the above conditions no longer exist,
the system will resume automatically. If the
“Unavailable: Side Radar Obstruction” warn-
ing message continues to appear, have the
system checked. It is recommended you visit
an INFINITI retailer for this service.
SYSTEM MALFUNCTION
When the BSI system malfunctions, it will be
turned off automatically, a chime will sound
and “Malfunction” warning message and
BSW indicator (orange) will appear in the
vehicle information display.
Action to take:
Stop the vehicle in a safe location, place the
shift lever in the P (Park) position, turn the
engine off and restart the engine.
If the message and BSW indicator (orange)
continue to appear, have the BSI system
checked. It is recommended you visit an
INFINITI retailer for this service.

SYSTEM MAINTENANCE
The two radar sensorsfor the BSI system
are located near the rear bumper. Always
keep the area near the radar sensors clean.
The radar sensors may be blocked by
temporary ambient conditions such as
splashing water, mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing
the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors.
Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors. Do not strike or damage the area around the
radar sensors.
It is recommended you visit an INFINITI
retailer if the area around the radar sensors
is damaged due to a collision.
The lane camera unit
for BSI system is
located above the inside mirror. To keep the
proper operation of BSI and prevent a
system malfunction, be sure to observe the
following:
. Always keep the windshield clean.
. Do not attach a sticker (including trans-
parent material) or install an accessory
near the camera unit.
. Do not place reflective materials, such as
white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.
. Do not strike or damage the areas around
the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit. It is recommended
you contact an INFINITI retailer if the
camera unit is damaged due to an
accident.

Radiofrequency radiation exposure informa-
tion:
This equipment complies with radiation ex-
posure limits set forth for an uncontrolled
environment. This equipment should be in-
stalled and operated with minimum distance
of 20 cm between the radiator and your
body.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.
JVS1152X
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.

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 issued to 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 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 upper display.
