How to change the set distance
to the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traf-
fic conditions.
Each time the DISTANCE switch
Ais
pushed, the set distance will change to
long, middle, short and back to long again,
in that sequence. Distance Approximate distance
at 60 mph (97 km/h)
[f t (m)]
1. Long 200 (60)
2. Middle 150 (45)
3. Short 90 (30)
• The distance to the vehicle ahead will change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
• The distance setting will remain at the current setting even if the EV system is
restarted.
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 indicatorblinks.
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:
• The vehicle approaches other vehicles that are parked or moving slowly.
• The accelerator pedal is depressed, over- riding the system.
5-66Starting and driving

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
vehicle.
Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the lane)
or traffic or vehicle condition (for ex-
ample, if a vehicle is being driven with
some damage).Acceleration when passing
When the ICC system is engaged above
43 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 the
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 ac-
celerate to the ICC system set speed. If an-
other vehicle is detected ahead, then the
vehicle will accelerate up to the following
speed of that vehicle. If the vehicle is not
steered into the lef t lane to pass, the accel-
eration will stop af ter a short time and re-
gain the set following distance. Accelera-
tion can be stopped at any point by
depressing the brake pedal or the CANCEL
switch on the steering wheel.WARNING
In order to reduce the risk of a collision
that may result in serious injury or
death, please be aware of the follow-
ing:
• This function is only activated with the lef t turn signal and will briefly
accelerate the vehicle even if a lane
change is not initiated. This can in-
clude non-passing situations such
as lef t side exits.
• Ensure that when passing another vehicle, the adjacent lane is clear be-
fore initiating the pass. Sudden
changes in traffic may occur while
passing.
– Always manually steer or brake asneeded
– Never solely rely on the system

Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed:
• When the vehicle ahead is not detectedand 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 or B mode
• When the parking brake system is applied
• When the VDC system is turned off
• When ABS or 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 interrupted
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE LIMITATIONS
WARNING
Listed below are the system limita-
tions for the ICC system. Failure to op-
erate the vehicle in accordance with
these system limitations could result
in serious 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 sys-
tem 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 sys-
tem does not correct careless, inat-
tentive or absentminded driving, or
overcome 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 stand-
still within the limitations of the sys-
tem. The system will cancel once it
judges that the vehicle has come to
a standstill and sound a warning
chime. To prevent the vehicle from
moving, the driver must depress the
brake pedal.
5-68Starting and driving

• 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
distance between vehicles (follow-
ing 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 heavyor 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 decelera-
tion
– 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. Al-
ways stay alert and avoid using the
ICC system where not recom-
mended 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 the cargo area of
your vehicle.
Starting and driving5-69

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.
5-70Starting and driving

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the ICC sen-
sor may detect vehicles in a different lane,
or may temporarily not detect a vehicle
traveling ahead. This may cause the ICC
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.

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 EV
system off. When the radar signal is tempo-
rarily interrupted, clean the sensor area of
the front bumper and restart the EV sys-
tem. If the “Not Available: Front Radar
Blocked” warning message continues to
be displayed, have the system checked. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for this service.• When driving on roads with limited road
structures or bridges (for example, long
bridges, deserts, snowfields, driving next
to long walls), the system may illuminate
the system warning light (orange) 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.
Condition C
When the ICC system is not operating
properly, a chime sounds and the ICC sys-
tem warning light (orange) will come on.
