–When rain, snow or dirt adheres to
the windshield in front of the lane
camera unit.
– When the headlights are not
bright due to dirt on the lens or if
the aiming is not adjusted
properly.
– When strong light enters the lane
camera unit (for example, the light
directly shines on the front of the
vehicle at sunrise or sunset).
– When a sudden change in bright-
ness occurs (for example, when
the vehicle enters or exits a tunnel
or under a bridge).
While the I-LI system is operating, you may
hear a sound of brake operation. This is
normal and indicates that the I-LI system is
operating properly.SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the I-LI
system are not designed to work under the
following conditions:
• When you operate the lane change signal and change the traveling lanes in the di-
rection of the signal. (The I-LI system will
be deactivated for approximately 2 sec-
onds af ter the lane change signal is
turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the warning and assist func-
tions will resume.
Condition B:
The assist function of the I-LI system is not
designed to work under the following con-
ditions (warning is still functional):
• When the brake pedal is depressed.
• When the steering wheel is turned as far as necessary for the vehicle to change
lanes.
• When the vehicle is accelerated during I-LI system operation. • When the Intelligent Cruise Control (ICC)
approach warning occurs.
• When the hazard warning flashers are operated.
• When driving on a curve at high speed.
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the I-LI system application of
the brakes will resume.
Condition C:
If the following messages appear in the
vehicle information display, a chime will
sound and the I-LI system will be turned off
automatically.
• “Not Available - Poor Road Conditions”: When the Vehicle Dynamic Control (VDC)
system (except Traction Control System
[TCS] function) or ABS operates.
• “Currently not available”: When the VDC system is turned off.
Action to take:
When the above conditions no longer exist,
turn off the I-LI system. Push the ProPILOT
Assist switch (models with ProPILOT Assist)
or dynamic driver assistance switch (mod-
els without ProPILOT Assist) to turn the I-LI
system back on.

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.

Starting and driving5-47

NOTE:
• I-BSI warning and system applicationwill only be activated if the side indica-
tor light is already illuminated when
your vehicle approaches a lane marker.
If another vehicle comes into the de-
tection zone af ter your vehicle has
crossed a lane marker, no I-BSI warn-
ing or system application will be acti-
vated. (For additional information, see
“I-BSI driving situations” (P. 5-50).).
• The I-BSI system is typically activated earlier than the Intelligent Lane Inter-
vention (I-LI) system when your vehicle
is approaching a lane marker.
To turn on the I-BSI system, push the ProPI-
LOT Assist switch on the steering wheel
(models with ProPILOT Assist) or the dy-
namic driver assistance switch (models
without ProPILOT Assist) af ter starting the
EV system. The I-BSI indicator will illumi-
nate. Push the ProPILOT Assist switch or
the dynamic driver assistance switch
again to turn off the I-BSI system. The I-BSI
indicator will turn off.
HOW TO ENABLE/DISABLE THE
I-BSI SYSTEMPerform the following steps to enable or
disable the I-BSI system:

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.
Starting and driving5-49

• When the parking brake is applied
• When the VDC operates (including thetraction control system)
• When a wheel slips
When the system is not operating properly,
the chime sounds and the color of the
cruise indicator will change to orange.
Action to take
If the color of the cruise indicator changes
to orange, stop the vehicle in a safe place
and place the shif t lever in the P (Park) po-
sition. Turn the EV system off, restart the EV
system, resume driving, and then perform
the setting again.
If it is not possible to set or the indicator
stays on, it may indicate that the system
is malfunctioning. Although the vehicle
is still drivable under normal conditions,
have the vehicle checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service.WARNING
Failure to follow the warnings and in-
structions for proper use of the ProPI-
LOT Assist system could result in seri-
ous injury or death.
• ProPILOT Assist is not a self-driving
system. Within the limits of its capa-
bilities, as described in this manual, it
helps the driver with certain driving
activities.
• The ProPILOT Assist system is not a
replacement for proper driving pro-
cedures and is not designed to cor-
rect careless, inattentive or absent-
minded driving. ProPILOT Assist will
not always steer the vehicle to keep it
in the lane. The ProPILOT Assist sys-
tem is not designed to prevent loss of
control. It is the driver’s responsibility
to stay alert, drive safely, keep the
vehicle in the traveling lane, and be in
control of the vehicle at all times. •
There are limitations to the ProPILOT
Assist system capability. The ProPI-
LOT Assist system does not function
in all driving, traffic, weather, and
road conditions. It is the driver’s re-
sponsibility to stay alert, drive safely,
keep the vehicle in the traveling lane,
and be in control of the vehicle at all
times.
• The ProPILOT Assist system is only an
aid to assist the driver and is not a
collision warning or avoidance
device.
• The ProPILOT Assist system is for
highway use only and is not intended
for city driving. Failure to apply the
brake or steer the vehicle when nec-
essary may result in a serious
accident.
• Always observe posted speed limits
and do not set the speed over them.
• Never take your hands off the steer-
ing wheel when driving. Always keep
your hands on the steering wheel
and drive your vehicle safely.
• Never unfasten your safety belt
when using ProPILOT Assist. Doing so
automatically cancels the ProPILOT
Assist system.

•The ProPILOT Assist system does not
react to stationary and slow-moving
vehicles.
• Always drive carefully and atten-
tively when using the ProPILOT Assist
system. Read and understand the
Owner’s Manual thoroughly before
using the ProPILOT Assist system. To
avoid serious injury or death, do not
rely on the system to prevent acci-
dents or to control the vehicle’s
speed in emergency situations. Do
not use the ProPILOT Assist system
except in appropriate road and traffic
conditions.
The ProPILOT Assist system is intended to
enhance the operation of the vehicle when
following a vehicle traveling in the same
lane and direction.
The ProPILOT Assist system uses a multi-
sensing front camera unit
OAinstalled be-
hind the windshield and a radar sensor lo-
cated on the front of the vehicle
OBto
measure the distance to the vehicle ahead
in the same lane and to monitor the lane
markers. If the vehicle detects a slower
moving vehicle ahead, the system will re-
duce the vehicle speed so that your vehicle
follows the vehicle in front at the selected
distance. The system will also help keep the vehicle centered in the traveling lane when
clear lane markings are detected.
