2021 NISSAN LEAF sensor

WARNING
Failure to follow the warnings and in-
structions for proper use of the BSW
system could result in serious injury or
death.
• The BSW system is not a replacement
for proper driving procedures and is
not designed to prevent contact with
vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the di-
rection your vehicle will move to en-
sure it is safe to change lanes. Never
rely solely on the BSW system.
The BSW system helps alert the driver of
other vehicles in adjacent lanes when
changing lanes. The BSW system uses radar sensors
O1
installed near the rear bumper to detect
other vehicles in an adjacent lane.
The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion zone shown as illustrated. This detec-
tion zone starts from the outside mirror of
your vehicle and extends approximately
10 f t (3.0 m) behind the rear bumper, and
approximately 10 f t (3.0 m) sideways.

BSW SYSTEM OPERATION
1. Side Indicator Light
2. BSW IndicatorThe 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 (1)
illuminates. If the turn signal is then acti-
vated, the system chimes (twice), the side
indicator light flashes, and the BSW indica-
tor (2) illuminates (yellow) in the vehicle in-
formation display. The side indicator light
continues to flash until the detected ve-
hicle leaves the detection zone.
The side indicator light illuminates for a few
seconds when the power switch is placed
in the ON position.
The brightness of the side indicator light is
adjusted automatically depending on the
brightness of the ambient light.
If a vehicle comes into the detection zone
af ter the driver activates the turn signal,
then only the side indicator light flashes
and no chime sounds. For additional infor-
mation, see “BSW driving situations”
(P. 5-40).
The BSW system automatically turns on
every time the EV system is started, as long
as it is activated using the settings menu
on the vehicle information display.

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 seri-
ous 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 cer-
tain objects are present such as:
– Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low
height vehicles, or high ground
clearance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detec-
tion 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
detection zone quickly.
– When overtaking several vehicles
in a row, the vehicles af ter the first
vehicle may not be detected if
they are traveling close together.
• 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 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 ig-
nore 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/dirt/snow build-up on
the vehicle •
Do not attach stickers (including
transparent material), install acces-
sories 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 win-
dow) will interfere with the chime
sound, and it may not be heard.

nates if a vehicle enters the detection zone
from behind in an adjacent lane.

Another vehicle approaching
from behind
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 ve- hicles 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 illu-
minates if you overtake a vehicle and that
vehicle stays in the detection zone for ap-
proximately 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 af ter the first vehicle
may not be detected if they are travel-
ing 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 illu-
minates 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 ve-
hicle which is traveling at about the
same speed as your vehicle when it en-
ters the detection zone.

SYSTEM TEMPORARILY
UNAVAILABLEWhen radar blockage is detected, the sys-
tem will be deactivated automatically. The
BSW indicator
O1will blink (yellow) in the
vehicle information display. The indicator next to “Blind spot” in the “Driving Aids”
menu
O2will also blink (yellow).
The system is not available until the condi-
tions no longer exist.
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
sensors.
NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
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 BSW indicator will il-
luminate (yellow) in the vehicle information
display. The indicator next to “Blind spot” in
the “Driving Aids” menu will also illuminate
(yellow).

Starting and driving5-43

NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the EV
system off and restart the EV system. If the
indicators continue to appear, have the
system checked. It is recommended that
you visit a NISSAN certified LEAF dealer for
this service.
SYSTEM MAINTENANCE
The two radar sensorsO1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the ra-
dar sensors clean.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors. Do not attach stickers (including transpar-
ent material), 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 certified LEAF dealer if
the area around the radar sensors is dam-
aged due to a collision.
