even roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshif t or
temporary lane.
– When driving on roads where the
lane width is too narrow.
– When driving without normal tire
conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, nonstan-
dard wheels).
– When the vehicle is equipped with
non-original brake parts or sus-
pension parts.
– When you are towing a trailer or
other vehicle. •
The system may not function prop-
erly under the following conditions:
– 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;
or lane markers covered with wa-
ter, dirt, snow, etc.
– On roads where the discontinued
lane markers are still detectable.
– On roads where there are sharp
curves.
– On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs. (The LDW system
could detect these items as lane
markers.)
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
marker.
– When traveling close to the ve-
hicle in front of you, which ob-
structs the lane camera unit de-
tection range. –
When rain, snow, dirt or an object
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).
SYSTEM TEMPORARILY
UNAVAILABLE

under high temperature conditions (over
approximately 104°F [40°C]) and then
started, the LDW system may be deacti-
vated automatically and the following
message will appear in the vehicle infor-
mation display: “Unavailable: High Cabin
Temperature.”
When the interior temperature is reduced,
the LDW system will resume operating au-
tomatically

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.

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, refer to “BSI driving situa-
tions” in this section.
– 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. –
On roads where discontinued lane
markers are still detectable.
– On roads where there are sharp
curves.
– On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs.
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
markers.
– When traveling close to the ve-
hicle in front of you, which ob-
structs the lane camera unit de-
tection range.
– When rain, snow or dirt adheres to
the windshield in front of a lane
camera unit.
– When the headlights are not
bright due to dirt on the lens or if
aiming is not adjusted properly.
– When strong light enters a lane
camera unit. (For example: light
directly shines on the front of the
vehicle at sunrise or sunset.)

7. Cargo light
8. License plate light
9. Fog light (if so equipped)
Fog may temporarily form inside the lens
of the exterior lights in the rain or in a car
wash. A temperature difference between
the inside and the outside of the lens
causes the fog. This is not a malfunction. If
large drops of water collect inside the lens,
it is recommended that you visit a NISSAN
certified LEAF dealer for this service.
HEADLIGHTS
If headlight bulb replacement is required, it
is recommended that you visit a NISSAN
certified LEAF dealer for this service.
Replacing the LED headlight bulb
(if so equipped)
If LED headlight bulb replacement is neces-
sary, it is recommended that you visit a
NISSAN certified LEAF dealer for this ser-
vice.
Replacing the halogen headlight
bulb (if so equipped)
The headlight is a semi-sealed beam type
that uses a headlight (halogen) bulb. If bulb
replacement is required, it is recom-
mended that you visit a NISSAN certified
LEAF dealer.
CAUTION
• Do not leave the bulb out of the head-
light reflector for a long period of
time. Dust, moisture, smoke, etc. en-
tering the headlight body may affect
bulb performance
• High-pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped. •
Only touch the base when handling
the bulb. Never touch the glass enve-
lope. Touching the glass envelope
could significantly affect bulb life
and/or headlight performance.
• Aiming is not necessary af ter replac-
ing the bulb. When aiming adjust-
ment is necessary, it is recom-
mended that you visit a NISSAN
certified LEAF dealer for this service.
• Fog may temporarily form inside the
lens of the exterior lights in the rain
or in a car wash. A temperature dif-
ference between the inside and the
outside of the lens causes the fog. If
large drops of water collect inside
the lens, it is recommended that you
visit a NISSAN certified LEAF dealer.
Use the same number and wattage as
originally installed as shown in the chart.
