SYSTEM MAINTENANCE
The two radar sensorsfor the BSW
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.

WARNING
Failure to follow the warnings and
instructions for proper use of the BSI
system could result in serious injury or
death.
.The BSI system is not a replacement
for proper driving procedures and is
not designed to prevent contact with
vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the
direction your vehicle will move to
ensure it is safe to change lanes.
Never rely solely on the BSI system.
. There is a limitation to the detection
capability of the radar. Not every
moving object or vehicle will be
detected. Using the BSI system under
some road, ground, lane marker,
traffic or weather conditions could
lead to improper system operation.
Always rely on your own operation to
avoid accidents.
The BSI system helps alert the driver of other
vehicles in adjacent lanes when changing
lanes, and helps assist the driver to return
the vehicle to the center of the traveling
lane.
JVS1125X
The BSI system uses radar sensorsinstalled near the rear bumper to detect
other vehicles in an adjacent lane. In addition
to the radar sensors, the BSI system uses a
camera
installed behind the windshield to
monitor the lane markers of your traveling
lane.

Detection zone
The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion zone shown as illustrated.
This detection zone starts from the outside
mirror of your vehicle and extends approxi-
mately 10 ft (3.0 m) behind the rear bumper,
and approximately 10 ft (3.0 m) sideways.

BSI SYSTEM OPERATION
The BSI system operates above approxi-
mately 37 MPH (60 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
illuminates.
If the turn signal is then activated, the
system chimes (twice) and the side indicator
light flashes. The side indicator light con-
tinues to flash until the detected vehicle
leaves the detection zone.
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. The BSI system operates
regardless of turn signal usage.
NOTE:
.BSI warning and system application will
only be activated if the side indicator
light is already illuminated when your
vehicle approaches a lane marker. If
another vehicle comes into the detection
zone after your vehicle has crossed a
lane marker, no BSI warning or system
application will be activated. (For addi-
tional information, see “BSI driving
situations” (P.5-55).)

3. Touch [Blind Spot Intervention] to en- able or disable the system.
Setting the side indicator light
brightness
The brightness of the side indicator lights
can be changed using the following steps:
1. Push the MENU button
and touch
[Driver Assistance] on the lower display.
2. Touch [Blind Spot Assist].
3. Touch [+] or [-] in [Side Indicator Bright- ness] to select [Bright], [Standard] or
[Dark].
When the brightness setting is changed, the
side indicator lights illuminate for a few
seconds.
BSI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSI system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The BSI system cannot detect all
vehicles under all conditions.
. The radar sensors may not be able to
detect and activate BSI when certain
objects are present such as: — Pedestrians, bicycles, animals.
— Vehicles such as motorcycles, low
height vehicles, or high ground
clearance vehicles.
— Vehicles remaining in the detec- tion zone when you accelerate
from a stop.
— Oncoming vehicles.
— A vehicle merging into an adja- cent lane at a speed approxi-
mately the same as your vehicle.
— A vehicle approaching rapidly from behind.
— A vehicle which your vehicle over- takes rapidly.
— A vehicle that passes through the detection zone quickly.
. The radar sensor’s detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect
vehicles in an adjacent lane. When
driving in a narrow lane, the radar
sensors may detect vehicles driving
two lanes away.
. The radar sensors are designed to
ignore most stationary objects, how-
ever objects such as guardrails, walls,

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.

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. .

before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the other
vehicle is detected.

. 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.
