Assist) on the steering wheel again to turn
the I-LI system back on.
Temporary disabled status at high tem-
perature:
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then the
I-LI system is turned on, the I-LI system
may be deactivated automatically and the
following message will appear on the ve-
hicle information display: “Unavailable: High
Cabin Temperature.” When the interior
temperature is reduced, the system will re-
sume operating automatically.
SYSTEM MALFUNCTION
If the I-LI system malfunctions, it will cancel
automatically. The LDW indicator (orange)
will illuminate in the display. If the LDW indi-
cator (orange) illuminates in the display,
pull off the road to a safe location and stop
the vehicle. Turn the engine/motor off and
restart the engine/motor. If the LDW indica-
tor (orange) continues to illuminate, have
the I-LI system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
SYSTEM MAINTENANCE
The lane camera unit1for the I-LI system
is located above the inside mirror. To keep
the proper operation of the I-LI system 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.
∙ 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.

5-44Starting and driving

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and main-
tain the speed up to the set speed. Pay
attention to the driving operation to main-
tain control of the vehicle as it accelerates
to the set speed.
The vehicle may not maintain the set
speed on winding or hilly roads. If this oc-
curs, you will have to manually control the
vehicle speed.Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is re-
quired for a lane change. Depress the brake
pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when us-
ing the ICC system.VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE SWITCHES
The system is operated by the ICC switch
and four control switches, all mounted on
the steering wheel.
1. CANCEL switch:
Deactivates the system without eras-
ing the set speed.
2. RES+ switch:
Resumes set speed or increases
speed incrementally.

Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle or if another vehicle cuts in, the sys-
tem warns the driver with the chime and
ICC system display. Decelerate by depress-
ing the brake pedal to maintain a safe ve-
hicle distance if:∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in
some cases when there is a short distance
between vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing.
∙ When the vehicle ahead is traveling faster and the distance between ve-
hicles is increasing.
∙ When a vehicle cuts in near your vehicle. The warning chime will not sound when:
∙ The vehicle approaches other vehicles that are parked or moving slowly.
∙ The accelerator pedal is depressed, overriding the system.
NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects objects on the
side of the vehicle or on the side of the
road. This may cause the ICC system to
decelerate or accelerate the vehicle. The
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
entering or exiting a curve. In these
cases you will have to manually control
the proper distance ahead of your ve-
hicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed: ∙ When the vehicle ahead is not detected and your vehicle is traveling below the
speed of 15 mph (24 km/h)
∙ When the system judges the vehicle is at a standstill
∙ When the shif t lever is not in the D (Drive) position, Manual mode or L (Low) range.
∙ When the parking brake system is ap- plied
∙ When the VDC system is turned off
∙ When VDC operates
∙
When distance measurement becomes
impaired due to adhesion of dirt or ob-
struction to the sensor
∙ When a wheel slips
∙ When the radar signal is temporarily in- terrupted
5-78Starting and driving

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
distance away from the vehicle traveling
ahead.

5-82Starting and driving

If it is not possible to set or the indicator
stays on, it may indicate that the system
is malfunctioning. Although the vehicle
is still drivable under normal conditions,
have the vehicle checked. It is recom-
mended that you visit a NISSAN dealer
for this service.WARNING
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-drivingsystem. 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 proce-
dures and is not designed to correct
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 ve-
hicle 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 responsi-
bility 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 steering 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 auto-
matically cancels the ProPILOT Assist
system.

PROPILOT ASSIST SYSTEM
OPERATION
The ProPILOT Assist system has the follow-
ing two functions:1. Intelligent Cruise Control (ICC)
The ICC system can be set to one of
two cruise control modes:
∙ Conventional (fixed speed) cruise
control mode: For cruising at a pre-
set speed
NOTE:
Steering Assist is not available in the
conventional (fixed speed) cruise control
mode.

Starting and driving5-93

∙Vehicle-to-vehicle distance control
mode: The ICC system maintains a
selected distance from the vehicle in
front of you within the speed range of
0 to 90 mph (0 to 144 km/h) up to the
set speed. The set speed can be se-
lected by the driver between 20 to
90 mph (32 to 144 km/h). When the
vehicle ahead slows to a stop, your
vehicle gradually decelerates to a
standstill. When the vehicle is
stopped, the ICC system maintains
braking force to keep your vehicle
stopped.
NOTE:
When your vehicle is stopped for less
than 3 seconds and the vehicle ahead
begins to move, your vehicle will start
moving again automatically. – When your vehicle is at a standstillfor more than 3 seconds and the
vehicle ahead begins to accelerate,
push the RES+ switch or lightly de-
press the accelerator pedal. The ICC
system starts to follow the vehicle
ahead. – When no vehicle is detected ahead
within the driver selected distance,
the vehicle travels at the speed set
by the driver. The speed must be
above 20 mph (32 km/h) to use this
function.
NOTE:
Even if the Automatic Emergency Brak-
ing (AEB) setting is turned off by the
driver using the “Settings” menu in the
vehicle information display, AEB will be
automatically turned on when ICC is
used. 2. Steering Assist
The Steering Assist function controls
the steering system to help keep your
vehicle within the traveling lane.
When there is no vehicle ahead, Steer-
ing Assist is not available at speeds
under 37 mph (60 km/h).
