2016 NISSAN SENTRA sensor

1. Side BSW/RCTA Indicator Light
2. BSW/RCTA Indicator
BSW SYSTEM OPERATION
The BSW system operates above approximately
20 mph (32 km/h).
If the radar sensors detect a vehicle in the detec-
tion zone, the side BSW/RCTA indicator light (1)
illuminates. If the turn signal is then activated, the
system chimes (twice) and the side BSW/RCTA
indicator light flashes. The BSW indicator light
continues to flash until the detected vehicles
leaves the detection zone.
The side BSW/RCTA indicator light illuminates
for a few seconds when the ignition switch is
placed in the ON position.
The brightness of the side BSW/RCTA indicator
light is adjusted automatically depending 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 BSW/RCTA indicator light flashes and no
chime sounds. For additional information, refer to
“BSW driving situations” in this section.

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the BSW system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
●The BSW system cannot detect all ve-
hicles under all conditions.
● The radar sensors may not be able to
detect and activate BSW when certain
objects are present such as:
– Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low height vehicles, or high ground clear-
ance vehicles.
– 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.
– 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
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect ve-
hicles in an adjacent lane. When driv-
ing in a narrow lane, the radar sen-
sors 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 occasionally be detected. This is
a normal operation condition.
● The following conditions may reduce
the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray – Ice/frost/snow build-up on the
vehicle
– 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.
● Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound, and
it may not be heard.

Illustration 1:The side BSW/RCTA indicator
light illuminates if a vehicle enters the detection
zone from behind in an adjacent lane.
Illustration 2:If the driver activates the turn
signal when another vehicle is in the detection
zone, then the system chimes (twice) and the
side indicator light flashes.
NOTE:
● The radar sensors may not detect vehicles
which are approaching rapidly from behind.
● 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.

Overtaking another vehicle
Illustration 3:The side indicator light illumi-
nates if you overtake a vehicle and that vehicle
stays in the detection zone for approximately
2 seconds. Illustration 4:
If the driver activates the turn
signal while another vehicle is in the detection
zone, then the system chimes (twice) and the
side indicator light flashes.
NOTE:
● When overtaking several vehicles in a row,
the vehicles after the first vehicle may not be
detected if they are traveling close together.
● The radar sensors may not detect slower
moving vehicles if they are passed quickly. ●
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.

Entering from the side
Illustration 5:The side indicator light illumi-
nates if a vehicle enters the detection 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 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. ●
The radar sensors may not detect a vehicle
which is traveling at about the same speed
as your vehicle when it enters the detection
zone.

SYSTEM TEMPORARILY
UNAVAILABLE
When radar blockage is detected, the system will
be deactivated automatically. The “Side Radar
Obstruction” warning message will appear and
the BSW/RCTA indicator (white) will blink
Ain
the vehicle information display.
The system is 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.
NOTE:
If the BSW system stops working, the RCTA
system (if so equipped) will also stop work-
ing.
Action to take:
When the above conditions no longer exist, the
system will resume automatically.

Malfunction
If the BSW system malfunctions, it will turn off
automatically. The system malfunction warning
message with the BSW/RCTA indicator (orange)
will appear in the vehicle information display.
NOTE:
If the BSW system stops working, the RCTA
system (if so equipped) will also stop work-
ing.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the engine off
and restart the engine. If the message continues
to appear, have the system checked. It is recom-
mended that you visit a NISSAN dealer for this
service.
SYSTEM MAINTENANCE
The two radar sensors1for the BSW and
RCTA systems are located near the rear bumper.
Always keep the area near the radar sensors
clean.
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.
Check for and remove objects obstructing the
area around the radar sensors. Do not attach stickers (including transparent ma-
terial) , install accessories or apply additional
paint near the radar sensors.
Do not strike or damage the area around the
radar sensors. It is recommended that you visit a
NISSAN dealer if the area around the radar sen-
sors is damaged due to a collision.
