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
1
illuminates.
If the turn signal is then activated, the system
chimes (twice) and the side indicator light
flashes. The side indicator light continues to
flash until the detected vehicle leaves the
detection zone.
If the BSI system is on and your vehicle ap-
proaches 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 re-
turn the vehicle back to the center of the
driving lane. The BSI system operates regard-
less 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 an-
other vehicle comes into the detection
zone after your vehicle has crossed a lane
marker, no BSI warning or system appli-
cation will be activated. For additional
information, refer to “BSI driving situa-
tions” in this section.
∙ The BSI system is typically activated
earlier than the Lane Departure Preven-
tion (LDP) system when your vehicle is
approaching a lane marker.
The BSI system turns on when the dynamic
driver assistance switch (for models without
ProPILOT Assist) or the ProPILOT Assist
switch (for models with ProPILOT Assist) on
the steering wheel is pushed when the “Blind
Spot Intervention” is enabled in the “Driver
Assistance” menu in the lower display. The
BSI ON indicator light on the instrument
panel illuminates when the BSI system is
turned on. The BSI system provides a chime and turns on
or flashes the side indicator light even if the
BSW system is off.

– On roads where there are sharply con-trasting objects, such as shadows,
snow, water, wheel ruts, seams or
lines remaining after road repairs.
– On roads where the traveling lane merges or separates.
– When the vehicle’s traveling direction does not align with the lane markers.
– When traveling close to the vehicle in front of you, which obstructs the lane
camera unit detection range.
– When rain, snow or dirt adheres to the windshield in front of a lane camera
unit.
– When the headlights are not bright due to dirt on the lens or if aiming is
not adjusted properly.
– When strong light enters a lane cam- era unit (e.g., light directly shines on
the front of the vehicle at sunrise or
sunset).
– When a sudden change in brightness occurs (e.g., when the vehicle enters or
exits a tunnel or under a bridge). ∙ Do not use the BSI system under the fol-
lowing conditions because the system
may not function properly:
– During bad weather (e.g., rain, fog, snow, etc.).
– When driving on slippery roads, such as on ice or snow, etc.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift lane.
– When driving on roads where the lane width is too narrow.
– When driving with a tire that is not within normal tire conditions (e.g., tire
wear, low tire pressure, installation of
spare tire, tire chains, nonstandard
wheels).
– When the vehicle is equipped with non-original brake parts or suspen-
sion parts.
∙ Do not use the BSI system when towing a trailer. ∙ Excessive noise (e.g., audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.

BSI DRIVING SITUATIONS
Another vehicle approaching from
behind
Illustration 1: The side indicator light illumi-
nates 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 side indicator light flashes.
NOTE:
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 3: If the BSI system is on and your
vehicle is approaching a lane marker and a
vehicle is in the detection zone, the system
chimes a sound (three times), and the side
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 4: If you accelerate from a stop
with a vehicle in the detection zone, the
other vehicle may not be detected.Overtaking another vehicle
Illustration 5: The side indicator light illumi-
nates if you overtake a vehicle and that ve-
hicle stays in the detection zone for approxi-
mately 3 seconds.
The radar sensors may not detect slower
moving vehicles if they are passed quickly.

which is traveling at about the same speed as
your vehicle when it enters the detection
zone.

Illustration 10: If the driver activates the turn
signal while another vehicle is in the detection
zone, then the side indicator light flashes and
a chime will sound twice.
NOTE:
If the driver activates the turn signal before
a vehicle enters the detection zone, the side

NOTE:
∙ Illustration 12: The BSI system will not
operate if your vehicle is on a lane marker
when another vehicle enters the detec-
tion zone. In this case, only the BSW sys-
tem 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 dur-
ing BSI system operation.

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 automatically.
∙ “Not Available Poor Road Conditions”: When the VDC system (except traction
control system function) or ABS oper-
ates.
∙ “Currently Not Available”: When the VDC system is turned off.
∙ “Not Available: High Camera Temp”: When the camera detects that the inte-
rior temperature is high (over approxi-
mately 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
illuminate.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the warning
light (orange) 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 ra-
dar sensors
2for the BSI system are located
near the rear bumper. To keep the proper
operation of the BSI system and prevent a
system malfunction, be sure to observe the
following:
∙ Always keep the windshield and the area near the radar sensors clean.
