2014 INFINITI Q50 Owner's Manual

5-42Starting and driving
.The radar sensors may not be able to
detect and activate BSI/BSW when
certain objects are present such as:
— Pedestrians, bicycles, animals
— Several types of vehicles such as
motorcycles
— Oncoming vehicles
— Vehicles remaining in the detection
zone when you accelerate from a
stop
— A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle
— A vehicle approaching rapidly from
behind.
— A vehicle which your vehicle over-
takes rapidly.
See also “BSW/BSI driving situations”
(P.5-43) for the situations in which the
radar sensors may not be able to detect
vehicle(s).
. Severe weather or road spray condi-
tions may reduce the ability of the
radar to detect other vehicles.
. The radar sensors’ 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 occa-
sionally be detected. This is a normal
operating condition.
. The camera may not detect lane mar-
kers 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 mar-
kers 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 direc-
tion 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
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.)

BSW/BSI DRIVING SITUATIONS
Another vehicle approaching from
behind
The side 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 side 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.
SSD1031
If the driver activates the turn signal, 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 the other vehicle is
detected.
SSD1044
If the BSI system is on and your vehicle is
approaching a lane marker, the side
indicator light flashes and a chime will
sound three times. Then the BSI system
slightly applies the steering to help return
the vehicle back to the center of the driving
lane.

NOTE:
If you accelerate from a stop with a vehicle
in the detection zone, the other vehicle
may not be detected.
SSD1033
Overtaking other vehicles
The side indicator light illuminates if you
overtake a vehicle and that vehicle stays in
the detection zone for approximately 3
seconds.
The radar sensors may not detect slower
moving vehicles if they are passed quickly.
SSD1034
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.

SSD1093
If the BSI system is on and your vehicle
approaches a 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 steering to help return
the vehicle back to the center of the driving
lane.
SSD1036
NOTE:
When overtaking several vehicles in a row,
the vehicles after the first vehicle may not
be detected if they are traveling close
together.

Entering from the side
The side indicator light illuminates if a
vehicle enters the detection zone from
either side.
NOTE:
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.
SSD1038
If the driver activates the turn signal, 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.
SSD1094
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 steering to help return
the vehicle back to the center of the driving
lane.

SSD1040
NOTE:
.The BSI system will not operate if your
vehicle is on a lane marker when
another vehicle enters the detection
zone. In this case only the BSW system
operates.
. BSI steering assist will not operate or
will stop operating and only a warning
chime will sound under the following
conditions.
— When the accelerator pedal is de-
pressed while steering control as-
sist is provided.
— When steering quickly —
When the ICC, DCA, predictive for-
ward collision warning or forward
emergency braking warnings sound.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
BSW/BSI temporarily not available
Condition A:
. Under the following conditions, the BSI
system will be turned off automatically,
a beep will sound and the “currently
unavailable” warning message will
appear in the vehicle information dis-
play. The BSW system is still available,
but the BSI system will not be available
until the conditions no longer exist.
— When the VDC system (except TCS
function) or ABS operates.
— When the VDC system is turned off.
— When the INFINITI Drive Mode Se-
lector is turned to the SNOW mode.
Action to take:
When the above conditions no longer exist,
push the dynamic driver assistance switch
again to turn the BSI system back on. Condition B:
BSW system: When radar blockage is
detected, the BSW system will be deacti-
vated automatically, the “side radar ob-
struction” warning message will appear
and the driver assist system blind spot
indicator (white) will blink in the vehicle
information display.
BSI system: When radar blockage is
detected, the BSI system will be turned
off automatically, a beep will sound and
the “side radar obstruction” warning mes-
sage will appear in the vehicle information
display.
The BSW and BSI systems are not available
until the conditions 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 BSW system will resume automatically.
For the BSI system, turn it on again. If the
driver assist system blind spot indicator
(white) continues to blink and/or the “side

pears even after the BSI system is turned
on again, stop the vehicle in a safe location
and turn the engine off. Check for and
remove objects obscuring the radar sen-
sors on the rear bumper, and restart the
engine.
Condition C:
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 1048F (408C)) and then the
BSI system is turned on, the BSI system
may be deactivated automatically. The
“high cabin temperature” warning mes-
sage will appear in the vehicle information
display.
Action to take:
When the above conditions no longer exist,
push the dynamic driver assistance switch
again to turn the BSI system back on.
BSW/BSI malfunction
When the BSW/BSI systems malfunction,
they will be turned off automatically, a
beep will sound, the and the system
“malfunction” warning message with the
driver assist system blind spot indicator
(orange) will appear in the vehicle informa-
tion display. Action to take:
Stop the vehicle in a safe location, 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 dis-
played, have the BSW/BSI systems
checked by an INFINITI retailer.
BACK-UP COLLISION INTERVENTION
(BCI) SYSTEM
The Back-up Collision Intervention (BCI)
system can help alert the driver of
approaching vehicles or rear objects when
the driver is backing out of a parking
space.
When the shift lever is in the R (Reverse)
position and the vehicle speed is less than
approximately 5 MPH (8 km/h), the BCI
system operates.JVS0233X
JVS0173X

JVS0234X
The BCI system uses radar sensors*1installed on both sides near the rear
bumper to detect an approaching vehicle
and sonar sensors
*2to detect objects in
the rear.
The radar sensors
*1detect the approach-
ing vehicle from up to approximately 49 ft
(15 m) away. The sonar sensors
*2detect
a rear obstacle at up to approximately 4.9
ft (1.5 m) from the bumper. Refer to the
illustration for approximate zone coverage
areas
*3.
If the radar detects a vehicle approaching
from the side or the sonar detects close
objects in the rear, the system gives visual and audible warnings, and then applies
the brake for a moment when the vehicle is
moving backwards. After the automatic
brake application, the driver must depress
the brake pedal to maintain brake pres-
sure. If the driver’s foot is on the accel-
erator pedal, the system pushes the
accelerator upward before applying the
brake. If you continue to press the accel-
erator, the system will not engage the
brake.
WARNING
.
The BCI system is not a replacement for
proper driving procedure and is not
designed to prevent contact with vehi-
cles or objects. When backing out of
parking space, always use the inside
and outside mirrors and turn and look in
the direction you will move. Never rely
solely on the BCI system.
. There is a limitation to the detection
capability of the radar and the sonar.
Using the BCI system under some road,
ground, lane marker, traffic or weather
conditions could lead to improper sys-
tem operation. Always rely on your own operation to avoid accidents.
