BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 MPH (32 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.
NOTE:
.The side indicator lights illuminate for a
few seconds when the ignition switch is
placed in the ON position.
. The brightness of the side indicator
lights is adjusted automatically depend-
ing on the brightness of the ambient
light.
. If a vehicle comes into the detection zone
after the driver activates the turn
signal, then only the side indicator light
flashes and no chime sounds. (See “BSW
driving situations” (P.5-43).)

Vehicle information display
SYSTEM TEMPORARILY UNA-
VAILABLE
When radar blockage is detected, the BSW
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 system is not available until the condi-
tions no longer exist.
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 “side radar obstruction” warning
message continues to appear, have the
system checked. It is recommended you visit
an INFINITI retailer for this service.
SYSTEM MALFUNCTION
When the BSW system malfunctions, it will
be turned off automatically, a chime will
sound, and the system “malfunction” warn-
ing message 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
BSW system checked. It is recommended
you visit an INFINITI retailer for this service.

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.5-53).)

TURNING THE BSI SYSTEM ON/
OFF
To turn on the BSI system, push the dynamic
driver assistance switchon the steering
wheel after starting the engine. The driver
assist system blind spot indicator (green)
in the vehicle information display will illumi-
nate.
Push the dynamic driver assistance switch
again to turn off the BSI system. The driver
assist system blind spot indicatorwill turn
off.
The dynamic driver assistance switch
is
used for Active Lane Control, Blind Spot
Intervention (BSI), Lane Departure Preven-
tion (LDP) and Distance Control Assist
(DCA) systems. When the dynamic driver
assistance switch
is pushed, Active Lane
Control, LDP and DCA systems will also turn
on or off simultaneously. The BSI system can
be individually set to on or off on the lower
display
.
If the system is set to off, the system will not
turn on even if the dynamic driver assistance
switch
is pushed to on. To set the system
to on or off on the lower display, see “How
to enable/disable the BSI system” (P.5-51).

BSI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations

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.
Starting and driving5-51

5-52Starting and driving
.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,
foliage and parked vehicles may oc-
casionally be detected. This is a
normal operation condition.
. The camera may not detect lane
markers in the following situations
and the BSI system may not operate
properly.
— On roads where there are multi- ple parallel lane markers; lane
markers that are faded or not
painted clearly; yellow painted
lane markers; nonstandard lane
markers; lane markers covered
with water, dirt, snow, etc.
— On roads where discontinued lane markers are still detectable.
— On roads where there are sharp curves.
— On roads where there are sharply contrasting objects, such as sha-
dows, 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 di-
rection does not align with the
lane markers.
— When traveling close to the ve- hicle in front of you, which ob-
structs 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 camera unit. (For example: light
directly shines on the front of the
vehicle at sunrise or sunset.)
— When a sudden change in bright- ness occurs. (For example: when
the vehicle enters or exits a tunnel
or under a bridge.)
. Do not use the BSI system under the
following conditions because the sys-
tem may not function properly.
— During bad weather. (For exam- ple: rain, fog, snow, etc.)
— When driving on slippery roads, such as on ice or snow, etc.

— When driving on winding or un-even roads.
— When there is a lane closure due to road repairs.
— When driving in a makeshift or temporary lane.
— When driving on roads where the lane width is too narrow.
— 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 steering 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.BSI DRIVING SITUATIONS
