2021 INFINITI QX50 light

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 ).

5-56Starting and driving

• The BSI system is typically activated ear-lier than the Lane Departure Prevention
(LDP) system when your vehicle is ap-
proaching a lane marker.
The BSI system turns on when the ProPILOT
Assist switch 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 on the instru-
ment 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.

–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.
Starting and driving5-59

–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, installa-
tion of spare tire, tire chains, non-
standard 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.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.

Entering from the side
Illustration 9: The side indicator light illumi-
nates if a vehicle enters the detection zone
from either side.

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
indicator light will flash but no chime will
sound when another vehicle is detected.Illustration 11: If the BSI system is on and
your vehicle approaches the lane marker
while another vehicle is in the detection zone,
the side indicator light flashes and a chime
will sound three times. 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.
NOTE:
• Illustration 12: The BSI system will not op-
erate 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.
