duce the vehicle speed so that your vehicle
follows the vehicle in front at the selected
distance.
The system automatically controls the
throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power)
if necessary.
The detection range of the sensor is ap-
proximately 650 f t (200 m) ahead.

The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, simi-
lar to standard cruise control, as long as no
vehicle is detected in the lane ahead. The
ICC system displays the set speed. Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
NOTE:
∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system.
∙ When the brake operates, a noise may
be heard. This is not a malfunction.
When a vehicle ahead is detected, the ve-
hicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance.
Vehicle ahead not detected
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE LIMITATIONS
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The ICC system is primarily intendedfor use on straight, dry, open roads
with light traffic. It is not advisable to
use the ICC system in city traffic or
congested areas.
∙ The ICC system will not adapt auto- matically to road conditions. This sys-
tem should be used in evenly flowing
traffic. Do not use the system on roads
with sharp curves, or on icy roads, in
heavy rain or in fog. ∙ As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absentminded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the ve-
hicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
∙ If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
∙ Always pay attention to the operation of 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 where the traffic is heavy or there are 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
5-78Starting 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.

Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The ICC system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.NOTE:
∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system.
∙ When the brake is applied by the sys-
tem, a noise may be heard. This is not
a malfunction.
When the ICC system detects a vehicle
ahead, the vehicle ahead detection indica-
tor and the speed control status indicator
(distance control mode) illuminates (solid
green
).
Vehicle ahead stops
When the vehicle ahead decelerates to
stop, your vehicle decelerates to a stand-
still. Once your vehicle stops, the ICC sys-
tem automatically applies the brakes to
keep the vehicle stopped. When your ve-
hicle is at a standstill, the “(RES+) Press to
start” message is displayed on the vehicle
information display.
NOTE:
When your vehicle stops for less than
3 seconds, your vehicle will automati-
cally follow the vehicle as it accelerates
from a stop. Vehicle ahead accelerates
When your vehicle is stopped and the ve-
hicle ahead begins to accelerate, push the
RES+ switch or lightly depress the accelera-
tor pedal. The ICC system starts to follow
the vehicle ahead.
Vehicle ahead not detected
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.
When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off
and speed control status indicator (main-
tain speed control mode) illuminates
(green outline
).
The ICC system gradually accelerates to
the set speed, but you can depress the
accelerator pedal to quickly accelerate.
When a vehicle is no longer detected and
your vehicle is traveling under approxi-
mately 15 mph (24 km/h), the ICC system
automatically cancels.

∙ 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.
