∙ The following conditions may reduce the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on the vehicle
∙ Do not attach stickers (including transparent material), install accesso-
ries or apply additional paint near the
radar sensors. These conditions may
reduce the ability of the radar to de-
tect other vehicles.
∙ Excessive noise (e.g., audio system volume, open vehicle window) will in-
terfere with the chime sound, and it
may not be heard. NOTE:
In the case of several vehicles approach-
ing in a row (Illustration 1) or in the oppo-
site direction (Illustration 2), a chime may
not be sounded by the RCTA system af-
ter the first vehicle passes the sensors.

– Interference by other radarsources
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the follow-
ing objects: ∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane
The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system
may not maintain the selected distance. The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly:
∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ When your vehicle is towing a trailer, etc.
∙ When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle.
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system.
When the sensor is covered with dirt or is
obstructed, the system will automatically
be canceled. If the sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them.
In these instances, the vehicle-to-vehicle
distance control mode may not cancel and
may not be able to maintain the selected
following distance from the vehicle ahead.
Be sure to check and clean the sensor
regularly. The detection zone of the radar sensor is
limited. A vehicle ahead must be in the de-
tection zone for the vehicle-to-vehicle dis-
tance detection mode to maintain the se-
lected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the centerline
of the lane. A vehicle that is entering the
lane ahead may not be detected until the
vehicle has completely moved into the
lane.
If this occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime. The driver may
have to manually control the proper dis-
tance away from vehicle traveling ahead.

∙ The ProPILOT Assist system does notreact to stationary and slow moving
vehicles.
∙ Always drive carefully and attentively when using the ProPILOT Assist sys-
tem. Read and understand the Own-
er’s Manual thoroughly before using
the ProPILOT Assist system. To avoid
serious injury or death, do not rely on
the system to prevent accidents or to
control the vehicle’s speed in emer-
gency situations. Do not use the Pro-
PILOT Assist system except in appro-
priate road and traffic conditions.
The ProPILOT Assist system is intended to
enhance the operation of the vehicle when
following a vehicle traveling in the same
lane and direction.
The ProPILOT Assist system uses a multi-
sensing front camera
Ainstalled behind
the windshield and a radar sensor located
on the front of the vehicle
Bto measure
the distance to the vehicle ahead in the
same lane and to monitor the lane mark-
ers. If the vehicle detects a slower moving
vehicle ahead, the system will reduce the
vehicle speed so that your vehicle follows
the vehicle in front at the selected distance. The system will also help keep the vehicle
centered in the traveling lane when clear
lane markings are detected.

Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the lane)
or traffic or vehicle conditions (for ex-
ample, if a vehicle is being driven with
some damage).
Acceleration when passing
When the ICC system is engaged above
37 mph and following a slower vehicle (be-
low ICC set speed), and the turn signal is
activated to the lef t, the ICC system will
automatically start to accelerate the ve-
hicle to help initiate passing on the lef t and
will begin to reduce the distance to vehicle
directly ahead. Only the lef t side turn signal
operates this feature. As the driver steers
the vehicle and moves into the passing
lane, if no vehicle is detected ahead the ICC
system will continue to accelerate to the
ICC system set speed. If another vehicle is
detected ahead, then the vehicle will accel-
erate up to the following speed of that ve-
hicle. If the vehicle is not steered into the
lef t lane to pass, the acceleration will stop
af ter a short time and regain the set follow-
ing distance. Acceleration can be stopped
at any point by depressing the brake pedal
or the CANCEL switch on the steering
wheel.

∙ Always pay attention to the operationof 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 with heavy, high-speed traffic or 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 ve- hicle may go beyond the set ve-
hicle speed and frequent braking
may result 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.
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The ICC system will not detect the following
objects: ∙ Stationary or slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane The following are some conditions in which
the radar sensor cannot properly detect a
vehicle ahead and the system may not op-
erate properly:
∙ When the sensor detection is reduced (conditions such as rain, snow, fog, dust
storms, sandstorms, and road spray
from other vehicles)
∙ Driving on a steep downhill slope or roads with sharp curves
∙ Driving on a bumpy road surface, such as an uneven dirt road
∙ If dirt, ice, snow or other material is cov- ering the radar sensor area
∙ A complicated-shaped vehicle such as a car carrier trailer or flatbed
truck/trailer is near the vehicle ahead.
∙ Interference by other radar sources
∙ When your vehicle is towing a trailer, etc.
∙ When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle.
The ICC system is designed to automati-
cally check the radar sensor’s operation
within the limitations of the 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 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 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 camera unit is damaged due to an
accident, it is recommended that you visit a
NISSAN dealer.
STEERING ASSIST

WARNING
Steering Assist is not a system for
hands-free driving. Always keep your
hands on the steering wheel and drive
your vehicle safely. Failure to do so
could cause a collision resulting in seri-
ous personal injury or death.
NOTE:
If the driver lightly touches (instead of
firmly grips) the steering wheel, the
steering torque sensor may not detect
the driver’s hand(s) on the wheel and a
sequence of warnings may occur. When
the driver holds and operates the steer-
ing wheel again, the warnings turn off.
Steering Assist limitations

WARNING
Failure to follow the warnings and in-
structions for proper use of the AEB
system could result in serious injury or
death.
∙ The AEB system is a supplemental aidto the driver. It is not a replacement
for the driver’s attention to traffic
conditions or responsibility to drive
safely. It cannot prevent accidents
due to carelessness or dangerous
driving techniques.
∙ The AEB system does not function in all driving, traffic, weather and road
conditions.
The AEB system can assist the driver when
there is a risk of a forward collision with the
vehicle ahead in the traveling lane. The AEB system uses a radar sensor
1
located on the front of the vehicle to mea-
sure the distance to the vehicle ahead in
the same lane.
