2021 NISSAN LEAF stop start

slower vehicle ahead. The system will de-
celerate the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to 40% of the
vehicle’s total braking power.
This system should only be used when traf-
fic conditions allow vehicle speeds to re-
main fairly constant or when vehicle
speeds change gradually. If a vehicle
moves into the traveling lane ahead or if a
vehicle traveling ahead rapidly decelerates,
the distance between vehicles may be-
come closer because the ICC system can-
not decelerate the vehicle quickly enough.
If this occurs, the ICC system will sound a
warning chime and blink the system dis-
play to notif y the driver to take necessary
action.
The system will cancel and a warning
chime will sound if the speed is below ap-
proximately 15 mph (24 km/h) and a vehicle
is not detected ahead. The system will also
disengage when the vehicle goes above
the maximum set speed.
For additional information, see “Approach
warning” (P. 5-77).The following items are controlled in the
vehicle-to-vehicle distance control mode:
• When there are no vehicles traveling
ahead, the vehicle-to-vehicle distance
control mode maintains the speed set by
the driver. The set speed range is be-
tween approximately 20 and 90 mph (32
and 144 km/h).
• When there is a vehicle traveling ahead, the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by the driver, from the
vehicle ahead. If the vehicle ahead comes
to a stop, the vehicle decelerates to a
standstill within the limitations of the sys-
tem. The system will cancel once it judges
a standstill with a warning chime.
• When the vehicle traveling ahead has moved out from its lane of travel, the
vehicle-to-vehicle distance control mode
accelerates and maintains vehicle speed
up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow-moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traf-
fic congestion. 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.

1. System set display with vehicle ahead
2. System set display without vehicleahead
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.

Starting and driving5-75

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 (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
canceled:
• 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 interrupted

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.

warning message 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 “Forward Driving Aids temporar-
ily disabled. Front Sensor blocked. See
Owner’s Manual” warning message contin-
ues to be displayed, have the system
checked. It is recommended that you visit a
NISSAN certified 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 “Forward Driving Aids tempo-
rarily disabled. Front Sensor blocked. See
Owner’s Manual” 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.

sition. Turn the EV system off, restart the EV
system, resume driving, and then perform
the setting again.
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 certified
LEAF 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-driving
system. 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 pro-
cedures and is not designed to cor-
rect 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
vehicle 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 re-
sponsibility 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
brake 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 steer-
ing 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
automatically cancels the ProPILOT
Assist system.

3. Steering-wheel-mounted control (right)4. ProPILOT Assist switch
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 preset
speed
NOTE:Steering Assist is not available in the
conventional (fixed speed) cruise con-
trol mode.
• 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 ve-
hicle ahead slows to a stop, your ve-
hicle gradually decelerates to a stand-
still. When the vehicle is stopped, the
ICC system maintains braking force to
keep your vehicle stopped.
LSD3658
Starting and driving5-93

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 standstill for more than 3 seconds and the vehicle
ahead begins to accelerate, push the
RES+ switch or lightly depress the accel-
erator 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) with Pedestrian Detection set-
ting is turned off by the driver using the
“Settings” menu in the vehicle informa-
tion display, AEB with Pedestrian Detec-
tion will be automatically turned on
when ICC is used. 2.
Steering Assist
The Steering Assist function controls the
steering system to help keep your ve-
hicle within the traveling lane.
When there is no vehicle ahead, Steering
Assist is not available at speeds under 37
mph (60 km/h).
