SYSTEM MAINTENANCE
The TSR system uses the same multi-
sensing front camera unit that is used by
the Lane Departure Warning (LDW) system,
located in front of the interior rearview mir-
ror. For additional information, refer to ”Sys-
tem maintenance” in the “Lane Departure
Warning (LDW)” section.
WARNING
Failure to follow the warnings and in-
structions for proper use of the LDW
system could result in serious injury or
death.
∙ This system is only a warning deviceto inform the driver of a potential un-
intended lane departure. It will not
steer the vehicle or 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. The LDW 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 LDW system monitors the lane mark-
ers on the traveling lane using the camera
unit
Alocated above the inside mirror.
The LDW system warns the driver that the
vehicle is beginning to leave the driving
lane with an indicator and a steering wheel
vibration. For additional information, refer
to “LDW system operation” in this section.

low tire pressure, installation of
spare tire, tire chains, nonstandard
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 water,
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 vehicle
in front of you, which obstructs the
lane camera unit detection 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 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

the LDW system will resume operating au-
tomatically.
The LDW system is not designed to warn
under the following conditions:∙ When you operate the lane change sig- nal and change traveling lanes in the
direction of the signal. (The LDW system
will become operable again 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 LDW functions will resume.
SYSTEM MALFUNCTION
If the LDW system malfunctions, it will can-
cel automatically and “Not Available Sys-
tem Malfunction” will appear in the vehicle
information display. If “Not Available Sys-
tem Malfunction” appears in the vehicle in-
formation display, pull off the road to a safe
location and stop the vehicle. Place the
shif t lever in the P (Park) position and the
ignition switch in the OFF position and re-
start the engine/motor. If “Not Available
System Malfunction” continues to appear in the vehicle information display, have the

∙ 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, 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
Alocated above the inside mirror.

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 youchange 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 corrective
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.
