The BSI system uses a camera1installed be-
hind the windshield to monitor the lane markers of
your traveling lane and radar sensors
2installed
near the rear bumper to detect other vehicles in
an adjacent lane.The BSI system operates above approximately
37 mph (60 km/h). If the system detects a vehicle
in the detection zone and your vehicle is ap-
proaching the lane marker, the BSI system pro-
vides an audible warning (three times) , flashes
the BSW indicator light and slightly applies the
brakes for a short period of time on one side to
help return the vehicle back to the traveling lane.
The BSI system provides an audible warning and
turns on or flashes the BSW indicator light even if
the BSW system is off.

BSI SYSTEM OPERATION
If the radar sensors detect vehicles in the detec-
tion zone, the BSW indicator light located near
the outside mirrors illuminates. If your vehicle is
approaching a lane marker, the system chimes a
sound (three times) and the BSW indicator light
flashes. Then the system applies the brakes on
one side of the vehicle for a moment to help return
the vehicle back to the center of the lane. BSI
operates regardless of turn signal usage.
NOTE:
Warning and brake control will only be ac-
tivated if the BSW 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 warning or brake
control will be activated. For additional in-
formation, refer to “BSI driving situations”
in this section. The BSI system is typically
activated earlier than the Lane Departure
Prevention (LDP) system when your vehicle
is approaching a lane marker.

BSI DRIVING SITUATIONS
Another vehicle approaching from
behind
Illustration 1: The Blind Spot Warning indicator
light illuminates if a vehicle enters the detection
zone from behind in an adjacent lane.
However, if the overtaking vehicle is traveling
much faster than your vehicle, the indicator light
may not illuminate before the detected vehicle is
beside your vehicle. 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.Illustration 2: If the driver activates the turn signal
then the system chimes a sound (twice) and the
Blind Spot Warning indicator light flashes.
NOTE:
If the driver activates the turn signal before
a vehicle enters the detection zone, the
BSW indicator light will flash but no chime
will sound when the other vehicle is de-
tected.Illustration 3: If the BSI system is on and your
vehicle is approaching a lane marker and a ve-
hicle is in the detection zone, the system chimes
a sound (three times) , and the BSW indicator
light flashes. Then the BSI system slightly applies
the brakes on one side to help return the vehicle
back to the center of the driving lane.

NOTE:
●Illustration 12: The BSI system will not oper-
ate if your vehicle is on a lane marker when
another vehicle enters the detection zone. In
this case, only the BSW system operates.
●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 during
BSI system operation.
– When steering quickly.– When the ICC, DCA, FCW or FEB warn-
ings sound.
– When the hazard warning flashers are
operated.
– When driving on a curve at a high speed.
SYSTEM TEMPORARILY
UNAVAILABLE
When any of the following messages appear on
the vehicle information display, a chime will sound
and the BSI system will be turned off automati-
cally.
●“Unavailable Road is slippery”:
When the VDC system (except traction con-
trol system function) or ABS operates.
●“Unavailable VDC OFF”:
When the VDC system is turned off.
●“Unavailable Snow mode active”:
When the drive mode select switch is turned
to the SNOW mode.
●“Unavailable High Cabin Temp.”:
When the camera detects that the interior
temperature is high (over approximately
104°F (40°C)) .
●“Unavailable Side Radar Obstruction”:
When side radar blockage is detected.Turn off the BSI system and turn it on again when
the above conditions no longer exist.
SYSTEM MALFUNCTION
When the BSI system malfunctions, it will be
turned off automatically, a chime will sound and
the BSI system warning light (orange) will illumi-
nate.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the engine off
and restart the engine. If the warning light (or-
ange) continues to illuminate, have the system
checked. It is recommended that you visit an
INFINITI retailer for this service.

SYSTEM MAINTENANCE
The lane camera unit1for the BSI system is
located above the inside mirror. The two radar
sensors
2for the BSI system are located near
the rear bumper. To keep the proper operation of
the BSI system and prevent a system malfunc-
tion, be sure to observe the following:
●Always keep the windshield and the area
near the radar sensors clean.●The radar sensors may be blocked by tem-
porary 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 camera unit or radar
sensors.
●Do not place reflective materials, such as
white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability of
detecting the lane markers.
●Do not strike or damage the area around the
radar sensors. Do not touch the camera lens
or remove the screw located on the camera
unit. It is recommended that you visit an
INFINITI retailer if the camera unit and/or
area around the radar sensors is damaged
due to a collision.

BCI SYSTEM OPERATION
When the shift lever is placed in R (Reverse)
position, the BCI ON appears in the vehicle infor-
mation display.
If the radar detects an approaching vehicle from
the side, the system chimes a sound (single
beep) , the Blind Spot Warning indicator light on
the side of the approaching vehicle flashes and a
yellow rectangular frame appears in display
A.NOTE:
●In the case of several vehicles approaching
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 so-
nar system detects an object behind the
vehicle and the BCI system detects an ap-
proaching vehicle at the same time the fol-
lowing indicators are provided:
– The sonar system chime sounds
– The Blind Spot Warning indicator light on
the side of the approaching vehicle
flashes and– A yellow rectangular frame appears in
display
If an approaching vehicle or object behind the
vehicle is detected when your vehicle is backing
up, a red frame will appear in the display
Aand
the system will chime three times. Then, the
brakes will be applied momentarily. After the au-
tomatic brake application, the driver must de-
press the brake pedal to maintain brake pressure.
If the driver’s foot is on the accelerator pedal, the
system moves the accelerator pedal upward be-
fore the braking is applied. However, if you con-
tinue to accelerate, the system will not engage
the brakes.
The system does not operate if the object is very
close to the bumper.
