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 replace- ment for proper driving procedures
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 your vehicle will move
to ensure 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
1
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. Detection zone

BSW SYSTEM OPERATION1. 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 information, re-
fer to “BSW driving situations” in this section
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 limita-
tions for the BSW system. Failure to op-
erate the vehicle in accordance with
these system limitations could result
in serious injury or death.
• The BSW system cannot detect all vehicles 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, lowheight 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 adja- cent lane at a speed approxi-
mately 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
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;
however, objects such as guardrails,
walls, foliage and parked vehicles
may occasionally be detected. This
is a normal operation condition.
• 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 (for example, audio system volume, open vehicle win-
dow) will interfere with the chime
sound, and it may not be heard.

NOTE:
• The radar sensors may not detect ve-
hicles which are approaching rapidly
from behind.
• 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.

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.

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.
Starting and driving5-45

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.
