2020 NISSAN LEAF warning

A warning chime will sound and a message
will pop up:
• When the VDC system is off (To use theICC system, turn on the VDC system. Push
the ICC switch to turn off the ICC system
and reset the ICC switch by pushing the
ICC switch again.)
For additional information about the
VDC system, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
• When VDC is operating
• When a wheel is slipping (To use the ICC system, make sure the wheels are no lon-
ger slipping.)
1. System set display with vehicle ahead
2.
System set display without vehicle 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.
When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 mph (24 km/h), the sys-
tem will be canceled.

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
OAis
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 in-
creasing.
• 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.

5-78Starting 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
example, 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 (below
ICC set speed), and the turn signal is acti-
vated to the lef t, the ICC system will auto-
matically start to accelerate the vehicle 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 signaloperates 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 accelerate to the
ICC system set speed. If another vehicle is
detected ahead, then the vehicle will accel-
erate up to the following speed of that ve-
hicle. If the vehicle is not steered into the
lef t lane to pass, the acceleration will stop
af ter a short time and regain the set follow-
ing distance. Acceleration 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 following:
• This function is only activated with
the lef t turn signal and will briefly ac-
celerate 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 as
needed
– 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 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 or B mode
• When the parking brake system is applied
• 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

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.
5-80Starting and driving

•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 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 your vehicle is towing a trailer, etc.
• 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.
Starting and driving5-81

Action to take
When the conditions listed above are no
longer present, turn the system off using
the ICC switch. Turn the ICC system back on
to use the system.
Condition B
• When the radar sensor area of the frontbumper is covered with dirt or is ob-
structed, the ICC system will automati-
cally 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 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.

Starting and driving5-85

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.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 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 certified LEAF dealer.
