Illustration 5:The side BSW/RCTA indicator
light illuminates if a vehicle enters the detec-
tion zone from either side. Illustration 6:
If the driver activates the turn
signal while another vehicle is in the detection
zone, then the system chimes (twice) and the
side BSW/RCTA indicator light flashes.
NOTE:
• If the driver activates the turn signal be- fore a vehicle enters the detection zone,
the side BSW/RCTA 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 detec-
tion zone.
SYSTEM TEMPORARILY
UNAVAILABLE
When radar blockage is detected, the system
will be deactivated automatically. The “Un-
available: Side Radar Obstruction” warning
message will appear in the vehicle informa-
tion display.

The BSI system uses radar sensorsO2in-
stalled near the rear bumper to detect other
vehicles in an adjacent lane. In addition to the
radar sensors, the BSI system uses a camera
O1installed behind the windshield to monitor
the lane markers of your traveling lane.
The radar sensors can detect vehicles on ei-
ther side of your vehicle within the detection
zone shown as illustrated. This detection
zone starts from the outside mirror of your
vehicle and extends approximately 10 ft (3.0
m) sideways.

BSI SYSTEM OPERATION
1. Side indicator light
2. BSW indicator3. BSI ON indicator
4. ProPILOT Assist switchThe 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 another ve-
hicle comes into the detection zone after
your vehicle has crossed a lane marker, no
BSI warning or system application will be
activated. For additional information, see
“BSI driving situations” (P. 5-60 ).

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 de-
tect and activate BSI when certain ob-
jects are present such as:
– Pedestrians, bicycles, or animals.
– Vehicles such as motorcycles, low
height vehicles, or high ground clear-
ance vehicles.
LSD3936
5-58Starting and driving

–Oncoming vehicles.
– Vehicles remaining in the detection
zone when you accelerate from a
stop. For additional information, see
“BSI driving situations” (P. 5-60).
– A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle. For additional
information, see “BSI driving situa-
tions” (P. 5-60).
– A vehicle approaching rapidly from
behind. For additional information,
see “BSI driving situations” (P. 5-60).
– A vehicle which your vehicle over-
takes rapidly. For additional infor-
mation, see “BSI driving situations”
(P. 5-60).
– A vehicle that passes through the de-
tection zone quickly.
– When overtaking several vehicles in a
row, the vehicles after the first ve-
hicle may not be detected if they are
traveling close together. •
The radar sensors’ detection zone is de-
signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an ad-
jacent lane. When driving in a narrow
lane, the radar sensors may detect ve-
hicles driving two lanes away.
• The radar sensors are designed to ignore
most stationary objects; however, ob-
jects such as guardrails, walls, foliage
and parked vehicles may occasionally be
detected. This is a normal driving
condition.
• The following conditions may reduce the
ability of the radar to detect other ve-
hicles:
– Severe weather
– Road spray
– Ice/frost/dirt build-up on the vehicle
• Do not attach stickers (including trans-
parent material), install accessories or
apply additional paint near the radar
sensors. These conditions may reduce
the ability of the radar to detect other
vehicles.
• The camera may not detect lane markers
in the following situations and the BSI
system may not operate properly: –
On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-
standard 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 shad-
ows, 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 cam-
era unit.
– When the headlights are not bright
due to dirt on the lens or if aiming is
not adjusted properly.

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.Illustration 6: If the driver activates the turn
signal while another vehicle is in the detection
zone, then the system chimes a sound (twice)
and the side indicator light flashes.
Illustration 7: If the BSI system is on and your
vehicle approaches a lane marker while an-
other vehicle is in the detection zone the sys-
tem chimes a sound (three times) and the side
indicator light flashes. Then, the BSI system
slightly applies the brakes on the appropriate
side to help return the vehicle back to the
center of the driving lane.

• The radar sensors may be blocked by tem-porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the radar sen-
sors. Check for and remove objects ob-
structing the area around the radar
sensors.
• Do not attach stickers (including transpar- ent material), install accessories or apply
additional 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
