LDW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the LDW system. Failure to follow
the warnings and instructions for
proper use of the LDW system could re-
sult in serious injury or death.
• The system will not operate at
speeds below approximately 37 mph
(60 km/h) or if it cannot detect lane
markers.
• Do not use the LDW 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, 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 re-
pairs. (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

SYSTEM TEMPORARILY
UNAVAILABLE
If the vehicle is parked in direct sunlight
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” or “Not available High cabin
temperature”.
When the interior temperature is reduced,
the LDW system will resume operating
automatically.
The LDW system is not designed to warn
under the following conditions:
• When you operate the lane change signaland change traveling lanes in the direc-
tion of the signal. (The LDW system will
become operable again approximately 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 LDW functions will resume.
SYSTEM MALFUNCTION
If the LDW system malfunctions, it will can-
cel automatically and “Not Available Sys-
tem Malfunction” or “System fault” will ap-
pear in the vehicle information display. If
“Not Available System Malfunction” or “Sys-
tem fault” appears in the vehicle informa-
tion display, pull off the road to a safe loca-
tion and stop the vehicle. Place the shif t
lever in the P (Park) position and the ignition
switch in the OFF position and restart the
engine/motor. If “Not Available System Mal-
function” or “System fault” continues to ap-
pear in the vehicle information display,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
SYSTEM MAINTENANCE
The lane camera unitO1for the LDW sys-
tem is located above the inside mirror. To
keep the proper operation of the LDW sys-
tem 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.
LSD3484
Starting and driving5-39

• Do not place reflective materials, such aswhite 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 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, ev-
ery 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
OAlocated above the inside mirror.

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.
