2021 NISSAN LEAF sensor

WARNING
Failure to follow the warnings and in-
structions for proper use of the I-BSI
system could result in serious injury or
death.
• The I-BSI system is not a replace-
ment for proper driving procedure
and is not designed to prevent con-
tact with vehicles or objects. When
changing lanes, always use the side
and rear mirrors and turn and look in
the direction you will move to ensure
it is safe to change lanes. Never rely
solely on the I-BSI system.
• There is a limitation to the detection
capability of the radar or the sonar.
Not every moving object or vehicle
will be detected. Using the I-BSI sys-
tem under some road, ground, lane
marker, traffic or weather conditions
could lead to improper system op-
eration. Always rely on your own op-
eration to avoid accidents.
The I-BSI system helps alert the driver of
other vehicles in adjacent lanes when
changing lanes, and helps assist the driver
to return the vehicle to the center of the
traveling lane. The I-BSI system uses radar sensors
O1
installed near the rear bumper to detect
other vehicles in an adjacent lane. In addi-
tion to the radar sensors, the I-BSI system
uses a camera
O2installed behind the
windshield to monitor the lane markers of
your traveling lane. The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion zone shown as illustrated.
The detection zone starts from the outside
mirror of your vehicle and extends approxi-
mately 10f t (3.0m) behind the rear bumper,
and approximately 10f t (3.0 m) sideways.

I-BSI SYSTEM OPERATION
The I-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 sys-
tem chimes (twice) and the side indicator
light flashes. The side indicator light contin-
ues to flash until the detected vehicle
leaves the detection zone. The brightness
of the side indicator light is adjusted auto-
matically depending on the brightness of
the ambient light.
If the I-BSI system is ON and your vehicle
approaches a lane marker while another
vehicle is in the detection zone, the system
chimes (three times) and the side indicator
light flashes. The I-BSI system activates to
help return the vehicle back to the center of
the driving lane. The I-BSI system operates
regardless of turn signal usage.

I-BSI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the I-BSI system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
• The I-BSI system cannot detect all
vehicles under all conditions.
• The radar sensors may not be able to
detect and activate I-BSI when cer-
tain objects are present such as:
– Pedestrians, bicycles, or animals.
– Vehicles such as motorcycles, low
height vehicles, or high ground
clearance vehicles.
– Vehicles remaining in the detec-
tion zone when you accelerate
from a stop. For additional infor-
mation, see “BSI driving situa-
tions” (P. 5-50).
– Oncoming vehicles.
– 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.
• 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 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 camera may not detect lane
markers in the following situations
and the I-BSI system may not oper-
ate properly.
– On roads where there are multiple
parallel lane markers; lane mark-
ers that are faded or not painted
clearly; yellow painted lane mark-
ers; non-standard lane markers;
lane markers covered with water,
dirt, snow, etc.

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 4: The side indicator light illumi-
nates if you overtake a vehicle and that

NOTE:
• When overtaking several vehicles in arow, 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 7: The side indicator light illumi-
nates if a vehicle enters the detection zone

SYSTEM MAINTENANCE
The two radar sensorsO1for the I-BSI sys-
tem are located near the rear bumper. Al-
ways keep the area near the radar 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 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 you visit a NISSAN cer-
tified LEAF dealer if the area around the
radar sensors is damaged due to a
collision.
The lane camera unit
O2for I-BSI system is
located above the inside mirror. To keep
the proper operation of I-BSI and prevent a
system malfunction, be sure to observe
the following:
• Always keep the windshield clean.
• Do not attach a sticker (including trans- parent material) or install an accessory
near the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.
