2019 NISSAN LEAF sensor

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 be-
fore a vehicle enters the detection zone,
the side indicator light will flash but no
chime will sound when the other vehicle
is detected.

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 be-
fore 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 sys-
tem will be deactivated automatically. The
BSW indicator
1will blink (yellow) in the
vehicle information display. The indicator
next to “Blind spot” in the “Driving Aids”
menu
2will 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 sen-
sors.
NOTE:
If the BSW system stops working, the
RCTA system (if so equipped) will also
stop working.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
5-44Starting and driving

Malfunction
If the BSW system malfunctions, it will turn
off automatically. The BSW indicator will
blink (yellow) in the vehicle information dis-
play. The indicator next to “Blind spot” in the
“Driving Aids” menu will also blink (yellow).
NOTE:
If the BSW system stops working, the
RCTA system (if so equipped) 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 sensors1for 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.

The RCTA system uses radar sensors1
installed on both sides near the rear bum-
per to detect an approaching vehicle.
The radar sensors
1can detect an ap-
proaching vehicle from up to approxi-
mately 66 f t (20 m) away.

RCTA SYSTEM LIMITATIONS
WARNING
Listed below are the system limita-
tions for the RCTA system. Failure to
operate the vehicle in accordance with
these system limitations could result
in serious injury or death.
• Always check surroundings and turn to check what is behind you before
backing up. The radar sensors de-
tect approaching (moving) vehicles.
The radar sensors cannot detect ev-
ery object such as:
– Pedestrians, bicycles, motor-cycles, animals or child-operated
toy vehicles
– A vehicle that is passing at speeds greater than approximately
19 mph (30 km/h)
– A vehicle that is passing at speeds lower than approximately 5 mph
(8 km/h)
• The radar sensors may not detect approaching vehicles in certain situ-
ations:
– Illustration a: When a vehicleparked next to you obstructs the
beam of the radar sensor.
5-50Starting and driving

– Illustration b: When the vehicle isparked in an angled parking
space.
– Illustration c: When the vehicle is parked on inclined ground.
– Illustration d: When an approach- ing vehicle turns into your vehi-
cle’s parking lot aisle.
– Illustration e: When the angle formed by your vehicle and ap-
proaching vehicle is small.
• The following conditions may re- duce the ability of the radar to de-
tect other vehicles:
– Severe weather
– Road spray
– Ice/frost/dirt/snow build-up onthe 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 (e.g., audio system volume, open vehicle window) will
interfere with the chime sound, and
it may not be heard.
NOTE:
In the case of several vehicles approach-
ing in a row (Illustration 1) or in the oppo-
site direction (Illustration 2), a chime may
not be sounded by the RCTA system af-
ter the first vehicle passes the sensors. Illustration 1
