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 intended
for 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
system 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
vehicle speed by depressing the
brake pedal, depending on the dis-
tance to the vehicle ahead and the
surrounding circumstances in order
to maintain 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 opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The ICC system may not
be able to maintain the selected dis-
tance between 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 un-
der 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
difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or
deceleration
– Interference by other radar
sources.
Starting and driving5-79

•In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Al-
ways stay alert and avoid using the
ICC system 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 excessively heavy baggage is loaded in the rear seat or the 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 center
line 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 the vehicle traveling
ahead.

properly a chime sounds and the ICC sys-
tem warning light (orange) will come on.
5-84Starting and driving

Action to take
If the warning light comes on, park the ve-
hicle in a safe place. Turn the EV system off,
restart the EV system, resume driving and
set the ICC system again.
If it is not possible to set the system or
the indicator stays on, it may indicate
that the system is malfunctioning. Al-
though the vehicle is still drivable under
normal conditions, have the vehicle
checked. It is recommended that you
visit a NISSAN certified LEAF dealer for
this service.
NOTE:
If the ICC system is temporarily unavail-
able, the conventional cruise control
mode may still be used. For additional
information, please see “Conventional
(fixed speed) cruise control mode”
(P. 5-87).
SYSTEM MAINTENANCE
The sensor for the ICC systemOAis 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.

5-86Starting and driving

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 unit
OAinstalled be-
hind the windshield and a radar sensor lo-
cated on the front of the vehicle
OBto
measure the distance to the vehicle ahead
in the same lane and to monitor the lane
markers. If the vehicle detects a slower
moving vehicle ahead, the system will re-
duce 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.
LSD3009
Starting and driving5-93

When passing another vehicle, the set
speed indicator
OBflashes when the ve-
hicle speed exceeds the set speed. The ve-
hicle ahead detection indicator turns off
when the area ahead of the vehicle is open.
When the pedal is released, the vehicle re-
turns to the previously set speed. Even
though your vehicle speed is set in the ICC
system, you can depress the accelerator
pedal when it is necessary to accelerate
your vehicle rapidly.
Cut-in detection
If a vehicle moves into your traveling lane
near your vehicle, the ICC system may in-
form the driver by flashing the vehicle
ahead detection indicator.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle 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 and set distance indicator blink.
• You judge it necessary to maintain a safe distance.
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 vehicles is
increasing. • When a vehicle cuts in near your vehicle.
The warning chime will not sound when:
• Your vehicle approaches other vehicles
that are parked or moving slowly.
• The accelerator pedal is depressed, over- riding the system.NOTE:
The approach warning chime may sound
and the system display may flash when
the radar 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
radar sensor may detect these objects
when the vehicle is driven on winding,
narrow, or hilly roads or when the vehicle
is entering or exiting a curve. In these
cases, you will have to manually control
the proper distance ahead of your
vehicle.
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).

•Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The ICC system may not
be able to maintain the selected dis-
tance between 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 un-
der 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 frequent
acceleration or deceleration
– Interference by other radar
sources
• In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Al-
ways stay alert and avoid using the
ICC system 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 cover- ing 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 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.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the de-
tection zone for the ICC system to maintain
the selected 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
center line of the lane. A vehicle that is en-
tering the lane ahead may not be detected
until the vehicle has completely moved into
the lane.
