Illustration 3: 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. The BSI system
activates to help return the vehicle back to
the center of the driving lane.
NOTE:
. The radar sensors may not detect vehi-
cles which are approaching rapidly from
behind.
. 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.

. 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 will not operate or will stop operat-
ing and only a warning chime will sound
under the following conditions.
— When the brake pedal is depressed.
(models without Direct Adaptive
Steering)
— 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.

Action to take:
When the above conditions no longer exist,
push the dynamic driver assistance switch
again to turn the BSI system back on.
When radar blockage is detected, the BSI
system will be turned off automatically, a
chime will sound and the “side radar ob-
struction” warning message will appear in
the vehicle information display
.
The BSI system is not available until the
conditions no longer exist. For additional
information, see “System maintenance”
(P.5-60).
Action to take:
When the above conditions no longer exist,
turn the BSI system on again. If the “side
radar obstruction” warning message ap-
pears even after the BSI system is turned
on again, stop the vehicle in a safe location,
place the shift lever in the P (Park) position
and turn the engine off. Check for and
remove objects obscuring the radar sensors
on the rear bumper, and restart the engine.
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F (40°C)) and then the
BSI system is turned on, the BSI system may
be deactivated automatically. The “high

Action to take:
When the interior temperature is reduced,
push the dynamic driver assistance switch
again to turn the BSI system back on.
SYSTEM MALFUNCTION
When the BSI system malfunctions, it will be
turned off automatically, a chime will sound,
and the system “malfunction” warning mes-
sage with the driver assist system blind spot
indicator (orange) will appear in the vehicle
information display.
Action to take:
Stop the vehicle in a safe location and place
the shift lever in the P (Park) position. Turn
the engine off and restart the engine. If the
system “malfunction” warning message with
the driver assist system blind spot indicator
(orange) continues to be displayed, 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.

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
Starting and driving5-63

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

Illustration 2 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.

— 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.
