Starting and driving5-111

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a ve-
hicle traveling ahead. This may cause the
radar system to decelerate or accelerate
the vehicle.
The detection of vehicles may also be af-
fected by vehicle operation (steering ma-
neuver or traveling position in the lane, etc.)
or vehicle condition.If this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime unexpectedly. You will
have to manually control the proper dis-
tance away from the vehicle traveling
ahead.
Automatic cancellation
The following are conditions in which the
ICC system may be temporarily unavail-
able. In these instances, the ICC system
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.Condition A
Under the following conditions, the ICC system
is automatically canceled. A chime will sound
and the system will not be able to be set:
∙ Any door is open.
∙ The driver’s seat belt is not fastened.
∙ The vehicle ahead is not detected and
your vehicle is traveling below the
speed of 15 mph (24 km/h).
∙ Your vehicle has been stopped by the ICC system for approximately 3 minutes
or longer.
∙ The shif t lever is not in the D (Drive) po- sition or manual shif t mode.
∙ The electronic parking brake is applied.
∙ The VDC system is turned off.
∙ The AEB applies harder braking.
∙ VDC (including the traction control sys- tem) operates.
∙ A wheel slips.
∙ When distance measurement be- comes impaired due to adhesion of dirt
or obstruction to the sensor.
∙ When the radar signal is temporarily in- terrupted.

Action to take:
When the conditions listed above are no
longer present, turn the system off using
the ProPILOT Assist switch. Turn the Pro-
PILOT Assist system back on to use the
system.
NOTE:
When the ICC system is canceled under
the following conditions at a standstill,
the electronic parking brake is auto-
matically activated:∙ Any door is open.
∙ The driver’s seat belt is not fastened.
∙ Your vehicle has been stopped by the
ICC system for approximately 3 min-
utes or longer.
∙ The shif t lever is not in the D (Drive)
position or manual shif t mode.
∙ The VDC system is turned off.
∙ When distance measurement be-
comes impaired due to adhesion of
dirt or obstruction to the sensor.
∙ When the radar signal is temporarily
interrupted. Condition B
When the radar sensor of the front bumper
is covered with dirt or is obstructed, the ICC
system will automatically be canceled.
The chime will sound and the “Not Avail-
able: Front Radar Blocked” warning mes-
sage will appear in the vehicle information
display.
Action to take:
If the warning message appears, stop the
vehicle in a safe place, place the shif t lever
in the P (Park) position, and turn the engine
off. When the radar signal is temporarily
interrupted, clean the sensor area of the
front bumper and restart the engine. If the
“Not Available: Front Radar Blocked” warn-
ing message continues to be displayed,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
Condition C
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next to
long walls), the system may illuminate the
system warning light and display the “Not
Available: Front Radar Blocked” message. Action to take:
When the above driving conditions no lon-
ger exist, turn the system back on.
ICC system malfunction
If the ICC system malfunctions, it will be
turned off automatically, a chime will
sound, and the speed control status warn-
ing (orange) will illuminate.
Action to take:
If the warning light comes on, stop the ve-
hicle in a safe place. Turn the engine off,
restart the engine and set the ICC system
again. If it is not possible to set the ICC
system or the indicator stays on, it may be
a malfunction. Although the normal driving
can be continued, the ICC system should
be inspected. It is recommended that you
visit a NISSAN dealer for this service.
ICC sensor maintenance
The radar sensor is located on the front of
the vehicle.
Starting and driving5-113

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
Failure to follow the warnings and in-
structions for proper use of the Steer-
ing Assist could result in serious injury
or death. ∙ The Steering Assist is not a replace-
ment for proper driving procedures
and is not designed to correct care-
less, inattentive or absent-minded
driving. The Steering Assist will not al-
ways steer the vehicle to keep it in the
lane. It is not designed to prevent loss
of control. It is the driver’s responsibil-
ity to stay alert, drive safely, keep the
vehicle in the traveling lane, and be in
control of the vehicle at all times.
∙ As there is a performance limit to the Steering Assist’s capability, never rely
solely on the system. The Steering
Assist does not function in all driving,
traffic, weather, and road conditions.
Always drive safely, pay attention
to the operation of the vehicle, and
manually control your vehicle
appropriately.
∙ The Steering Assist is intended for use on well-developed freeways or high-
ways with gentle (moderate) curves.
To avoid risk of an accident, do not use
this system on local or non-highway
roads.
5-114Starting and driving

∙ The Steering Assist only steers the ve-hicle to maintain its position in the
center of a lane. The vehicle will not
steer to avoid objects in the road in
front of the vehicle or to avoid a ve-
hicle moving into your lane.
∙ 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. Never take
your hands off the steering wheel
when driving. Always keep your hands
on the steering wheel and drive your
vehicle safely.
∙ Always drive carefully and attentively when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering
Assist. To avoid serious injury or
death, do not rely on the system to
prevent accidents or to control the ve-
hicle’s speed in emergency situations.
Do not use the Steering Assist except
in appropriate road and traffic
conditions.Steering Assist operation
The Steering Assist controls the steering
system to help keep your vehicle near the
center of the lane when driving. The Steer-
ing Assist is combined with the Intelligent
Cruise Control (ICC) system. For additional
information, refer to “Intelligent Cruise Con-
trol (ICC) (for vehicles with ProPILOT Assist)”
in this section.
The Steering Assist can be activated when
the following conditions are met:
∙ The ICC system is activated.
∙ Lane markers on both sides are clearly detected.
∙ A vehicle ahead is detected (when the vehicle is driven at speeds under
37 mph [60 km/h]).
∙ The driver grips the steering wheel.
∙ The vehicle is driven at the center of the lane.
∙ The turn signals are not operated.
∙ The windshield wiper is not operated in the high (HI) speed operation (the
Steering Assist function is disabled
af ter the wiper operates for approxi-
mately 10 seconds).

mation display turn gray and a chime
sounds twice.
Intelligent Lane Intervention (I-LI)
When a curve or strong cross wind exceeds
the capabilities of the Steering Assist and
your vehicle approaches either the lef t or
the right side of the traveling lane, the I-LI
indicator (orange) on the instrument panel
flashes to alert the driver. Then, the I-LI sys-
tem automatically applies the brakes for a
short period of time to help assist the
driver to return the vehicle to the center of
the traveling lane. This action is in addition
to any Steering Assist actions.
5-116Starting and driving

Hands on detection
When the Steering Assist is activated, it
monitors the driver’s steering wheel opera-
tion.
If the steering wheel is not operated or the
driver takes his/her hands off the steering
wheel for a period of time, the warning
1
appears in the vehicle information display.
If the driver does not operate the steering
wheel af ter the warning has been dis-
played, an audible alert sounds and the
warning flashes in the vehicle information
display, followed by a quick brake applica-
tion to request the driver to take control of
the vehicle again.
If the driver still does not respond, the Pro-
PILOT Assist turns on the hazard flasher
and slows the vehicle to a complete stop.
The driver can cancel the deceleration at
any time by steering, braking, accelerating,
or operating the ProPILOT Assist switch.

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
∙ In the following situations, the cam- era may not detect lane markers cor-
rectly or may detect lane markers in-
correctly and the Steering Assist may
not operate properly: – When driving on roads where there
are multiple parallel lane markers,
lane markers that are faded or not
painted clearly, nonstandard lane
markers, or lane markers covered
with water, dirt, snow, etc.
– When driving on roads with dis- continued lane markers
– When driving on roads with a wid- ening or narrowing lane width
– When driving on roads where there are multiple lanes or unclear lane
markers due to road construction
– When driving on roads where there are sharply contrasting objects,
such as shadows, snow, water,
wheel ruts, seams, or lines remain-
ing af ter road repairs (the Steering
Assist could detect these items as
lane markers)
– When driving on roads where the traveling lane merges or separates ∙ Do not use the Steering Assist under
the following conditions because the
system may not properly detect lane
markers. Doing so could cause a loss
of vehicle control and result in an
accident.
– During bad weather (rain, fog, snow, dust, etc.)
– When rain, snow, sand, etc., is thrown up by the wheels of other
vehicles
– When dirt, oil, ice, snow, water, or another object adheres to the
camera unit
– When the lens of the camera unit is foggy
– When strong light (for example, sunlight or high beams from on-
coming vehicles) shines on the
camera
– When the headlights are not bright due to dirt on the lens or the head-
lights are off in tunnels or darkness
– When a sudden change in bright- ness occurs (for example, when the
vehicle enters or exits a tunnel or is
under a bridge)
