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-driving
system. 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 pro-
cedures and is not designed to cor-
rect 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
vehicle 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 re-
sponsibility 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 steer-
ing 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
automatically cancels the ProPILOT
Assist system.

ICC sensor maintenance
The radar sensor is located on the front of
the vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
• Always keep the sensor area of the front
bumper/emblem clean.
• Do not strike or damage the areas around the sensor.
• Do not attach a sticker (including trans- parent material) or install an accessory
near the sensor. This could cause failure
or malfunction.
• Do not attach metallic objects near the sensor area (brush guard, etc.). This could
cause failure or malfunction.
• Do not alter, remove, or paint the front bumper. Before customizing or restoring the front
bumper, it is recommended that you visit a
NISSAN dealer.
The camera sensor is located above the
inside mirror.
To keep the proper operation of the sys-
tems 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.

camera lens or remove the screw located
on the camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit a
