I-LI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the I-LI system. Failure to follow the
warnings and instructions for proper
use of the I-LI system could result in
serious injury or death.
• The I-LI system may activate if you
change lanes without first activating
your turn signal or, for example, if a
construction zone directs traffic to
cross an existing lane marker. If this
occurs you may need to apply correc-
tive steering to complete your lane
change.
• Because the I-LI may not activate un-
der the road, weather, and lane
marker conditions described in this
section, it may not activate every
time your vehicle begins to leave its
lane and you will need to apply cor-
rective steering.
• When the I-LI system is operating,
avoid excessive or sudden steering
maneuvers. Otherwise, you could
lose control of the vehicle. •
The I-LI system will not operate at
speeds below approximately 37 mph
(60 km/h) or if it cannot detect lane
markers.
• Do not use the I-LI system under the
following conditions as it may not
function properly:
– During bad weather (rain, fog,
snow, etc.).
– When driving on slippery roads,
such as on ice or snow.
– When driving on winding or un-
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, non-
standard wheels).
– When the vehicle is equipped with
nonoriginal brake parts or sus-
pension parts.
– When you are towing a trailer or
other vehicle. –
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 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 I-LI 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.
Starting and driving5-43

–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, the I-LI system
will be turned off automatically.
• “Not Available Poor Road Conditions”: When the 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 (for vehicles with ProPILOT
Assist) on the steering wheel again to turn
the I-LI system back on.
5-44Starting and driving

Temporary disabled status at high
temperature:
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then the
I-LI system is turned on, the I-LI system
may be deactivated automatically and the
following message will appear on the ve-
hicle information display: “Unavailable: High
Cabin Temperature.” When the interior
temperature is reduced, the system will re-
sume operating automatically.
SYSTEM MALFUNCTION
If the I-LI system malfunctions, it will cancel
automatically. The LDW indicator (orange)
will illuminate in the display. If the LDW indi-
cator (orange) illuminates in the display,
pull off the road to a safe location and stop
the vehicle. Turn the engine/motor off and
restart the engine/motor. If the LDW indica-
tor (orange) continues to illuminate, have
the I-LI system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
SYSTEM MAINTENANCE
The lane camera unitO1for the I-LI system
is located above the inside mirror. To keep
the proper operation of the I-LI system 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.
• Do not strike or damage the areas around the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit. If the camera unit is
damaged due to an accident, it is recom-
mended that you visit a NISSAN dealer.

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 replacement
for proper driving procedures and is
not designed to prevent contact with
vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the di-
rection your vehicle will move to en-
sure 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
O1
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 ap-
proximately 10 f t (3.0 m) sideways.

2. BSW indicator
BSW SYSTEM OPERATION
The BSW system operates above approxi-
mately 20 mph (32 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side BSW/RCTA indica-
tor light (1) illuminates. If the turn signal is
then activated, the system chimes (twice),
the side BSW/RCTA indicator light flashes
and the BSW indicator illuminates (yellow)
in the vehicle information display. The side
BSW/RCTA indicator light continues to
flash until the detected vehicle leaves the
detection zone.
The side BSW/RCTA indicator light illumi-
nates for a few seconds when the ignition
switch is placed in the ON position.
If a vehicle comes into the detection zone
af ter the driver activates the turn signal,
then only the side BSW/RCTA indicator light
flashes and no chime sounds. For addi-
tional information, see “BSW driving situa-
tions” (P. 5-52).
The BSW system automatically turns on
every time the engine is started, as long as
it is activated using the settings menu on
the vehicle information display.
