∙ Do not place reflective materials, suchas 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 mark-
ers.
∙ 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 cam-
era unit is damaged due to an accident,
it is recommended that you visit a
NISSAN dealer.
WARNING
Failure to follow the warnings and in-
structions for proper use of the I-LI sys-
tem could result in serious injury or
death.
∙ The I-LI system will not steer the ve-hicle or 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. ∙ The I-LI system is primarily intended
for use on well-developed freeways or
highways. It may not detect the lane
markers in certain road, weather, or
driving conditions.
The I-LI system must be turned on with the
ProPILOT Assist switch (for vehicles with
ProPILOT Assist) on the steering wheel,
every time the ignition is placed in the ON
position.
The I-LI system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The I-LI system warns the driver when the
vehicle has lef t the center of the traveling
lane with an indicator and a steering wheel
vibration. The system helps assist the
driver to return the vehicle to the center of
the traveling lane by applying the brakes to
the lef t or right wheels individually (for a
short period of time).
The I-LI system monitors the lane markers
on the traveling lane using the camera unit
Alocated above the inside mirror.

I-LI SYSTEM OPERATION
The I-LI system operates above approxi-
mately 37 mph (60 km/h). When the vehicle
approaches either the lef t or the right side
of the traveling lane, the steering wheel will
vibrate and the LDW indicator (orange) on
the instrument panel will blink to alert the
driver. Then, the I-LI system will automati-
cally apply the brakes for a short period of
time to help assist the driver to return the
vehicle to the center of the traveling lane.
To turn on the I-LI system, push the Pro-
PILOT Assist switch (for vehicles with Pro-
PILOT Assist) on the steering wheel af ter
starting the engine/motor. The I-LI indica-
tor on the instrument panel will illuminate.
Push the ProPILOT Assist switch again to
turn off the I-LI system. The I-LI indicator will
turn off.

lane camera unit detection range.
– 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 aim-
ing 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 sig- nal and change the traveling lanes in
the direction of the signal. (The I-LI sys-
tem will be deactivated for approxi-
mately 2 seconds 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

If the radar sensor1detects 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 automatically controls the
throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power)
if necessary.
The detection range of the sensor is ap-
proximately 650 f t (200 m) ahead.

ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, simi-
lar to standard cruise control, as long as no
vehicle is detected in the lane ahead. The
ICC system displays the set speed. Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
NOTE:
∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system.
∙ When the brake operates, a noise may
be heard. This is not a malfunction.
When a vehicle ahead is detected, the ve-
hicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance.
Vehicle ahead not detected
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE LIMITATIONS
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The ICC system is primarily intendedfor use on straight, dry, open roads
with light traffic. It is not advisable to
use the ICC system in city traffic or
congested areas.
∙ The ICC system will not adapt auto- matically to road conditions. This sys-
tem should be used in evenly flowing
traffic. Do not use the system on roads
with sharp curves, or on icy roads, in
heavy rain or in fog. ∙ As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absentminded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the ve-
hicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
∙ If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
∙ Always pay attention to the operation of the vehicle and be ready to manu-
ally control the proper following dis-
tance. The ICC system may not be able
to maintain the selected distance be-
tween vehicles (following distance) or
selected vehicle speed under some
circumstances. ∙ The system may not detect the ve-
hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system under
the following conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance
sensor
–
On steep downhill roads (the vehicle
may go beyond the set vehicle
speed and frequent braking may re-
sult in overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it dif- ficult to keep a proper distance be-
tween vehicles because of fre-
quent acceleration or deceleration
–
Interference by other radar sources

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 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-drivingsystem. 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 proce-
dures and is not designed to correct
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 ve-
hicle 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 responsi-
bility 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
brakes 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 steering 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 auto-
matically cancels the ProPILOT Assist
system.
