brake NISSAN LEAF 2021 Owner´s Manual

•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
difficult to keep a proper distance
between vehicles because of fre-
quent 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.
5-108Starting and driving

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a ve-
hicle traveling ahead. This may cause the
radar 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 sound-
ing the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.
Automatic cancellation
The following are conditions in which the
ICC system may be temporarily unavail-
able. In these instances, the ICC system
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.Condition A
Under the following conditions, the ICC sys-
tem is automatically canceled. A chime will
sound and the system will not be able to be
set:
• Any door is open.
• The driver’s seat belt is not fastened.
• The vehicle ahead is not detected and
your vehicle is traveling below the speed
of 15 mph (24 km/h).
• Your vehicle has been stopped by the ICC system for approximately 3 minutes or
longer.
• The shif t lever is not in the D (Drive) posi- tion or B mode.
• The electronic parking brake is applied.
• The Vehicle Dynamic Control (VDC) sys- tem is turned off.
• The Automatic Emergency Braking with Pedestrian Detection applies harder
braking.
• VDC (including the traction control sys- tem) operates.
• A wheel slips.
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor.

tinues to be displayed, have the system
checked. It is recommended that you visit a
NISSAN certified LEAF dealer for this
service.
Condition C
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snowfields, driving next to
long walls), the system may illuminate the system warning light and display the "For-
ward Driving Aids temporarily 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.
ICC system malfunction
If the ICC system malfunctions, it will be
turned off automatically, a chime will
sound, and the speed control status warn-
ing (orange) will illuminate.
Action to take:
If the warning light comes on, stop the ve-
hicle in a safe place. Turn the EV system off,
restart the EV system and set the ICC sys-
tem again. If it is not possible to set the ICC
system or the indicator stays on, it may be
a malfunction. Although the normal driving
can be continued, the ICC system should
be inspected. It is recommended that you
visit a NISSAN certified LEAF dealer for this
service.

marker indicator (3) on the vehicle informa-
tion display turn green. A chime sounds
when the Steering Assist initially activates. When the Steering Assist deactivates, the
Steering Assist status indicator (1), the
Steering Assist indicator (2), and the lane
marker indicator (3) on the vehicle informa-
tion display turn gray and a chime sounds
twice.
Intelligent Lane Intervention (I-LI)
When a curve or strong cross wind exceeds
the capabilities of the Steering Assist and
your vehicle approaches either the lef t or
the right side of the traveling lane, a warn-
ing chime sounds and the I-LI indicator
light (orange) on the instrument panel
flashes to alert the driver. Then, the I-LI sys-
tem automatically applies the brakes for a
short period of time to help assist the
driver to return the vehicle to the center of
the traveling lane. This action is in addition
to any Steering Assist actions.
5-114Starting and driving

Hands on detectionWhen the Steering Assist is activated, it
monitors the driver’s steering wheel
operation.If the steering wheel is not operated or the
driver takes his/her hands off the steering
wheel for a period of time, the warning
O1
appears in the vehicle information display.
If the driver does not operate the steering
wheel af ter the warning has been dis-
played, an audible alert sounds and the
warning flashes in the vehicle information
display, followed by a quick brake applica-
tion to request the driver to take control of
the vehicle again.
If the driver still does not respond, the Pro-
PILOT Assist turns on the hazard flasher
and slows the vehicle to a complete stop.
The driver can cancel the deceleration at
any time by steering, braking, accelerating,
or operating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for
hands-free driving. Always keep your
hands on the steering wheel and drive
your vehicle safely. Failure to do so
could cause a collision resulting in seri-
ous personal injury or death.

•Do not use the Steering Assist under
the following conditions because the
system will not operate properly:
– When driving with a tire that is not
within normal tire conditions (for
example, tire wear, abnormal tire
pressure, installation of a spare
tire, tire chains, nonstandard
wheels)
– When the vehicle is equipped with
non-original brake or suspension
parts
– When an object such as a sticker
or cargo obstructs the camera
– When excessively heavy baggage
is loaded in the rear seat or lug-
gage area of your vehicle
– When the vehicle load capacity is
exceeded
• Excessive noise will interfere with the
warning chime sound, and the beep
may not be heard. •
For the ProPILOT Assist system to op-
erate properly, the windshield in
front of the camera must be clean.
Replace worn wiper blades. The cor-
rect size wiper blades must be used
to help make sure the windshield is
kept clean. Only use Genuine NISSAN
wiper blades, or equivalent wiper
blades, that are specifically designed
for use on your vehicle model and
model year. It is recommended that
you visit a NISSAN certified LEAF
dealer for the correct parts for your
vehicle.

operation:
When the driver activates the turn signal,
the Steering Assist is temporarily placed in
a standby mode. (The Steering Assist re-
starts automatically when the operating
conditions are met again.)
Automatic standby:
In the following cases, a warning message
is displayed along with the chime, and the
Steering Assist is placed in a temporary
standby mode. (The Steering Assist re- starts automatically when the operating
conditions are met again.)
• When lane markers on both sides are no
longer detected
• When a vehicle ahead is no longer de- tected under approximately 37 mph (60
km/h)
Steering Assist cancel
Under the following conditions, the Steer-
ing Assist cancels, and the Steering Assist
status indicator and the Steering Assist in-
dicator turn off, and the “Not Available Bad
Weather” warning message will appear:
• When unusual lane markers appear inthe traveling lane or when the lane
marker cannot be correctly detected for
some time due to certain conditions (for
example, a snow rut, the reflection of light
on a rainy day, the presence of several
unclear lane markers)
• When the windshield wiper operates in the high (HI) speed operation (the Steer-
ing Assist is disabled when the wiper op-
erates for more than approximately 10
seconds)

To set cruising speed, accelerate your ve-
hicle to the desired speed, push the SET- ©
switch and release it. (The color of the
cruise indicator changes to green and set
vehicle speed indicator comes on.) Take
your foot off the accelerator pedal. Your
vehicle will maintain the set speed.
• To pass another vehicle, depress the ac-celerator pedal. When you release the
pedal, the vehicle will return to the previ-
ously set speed.
• The vehicle may not maintain the set speed when going up or down steep hills.
If this happens, manually maintain ve-
hicle speed. To cancel the preset speed, use any of the
following methods:
1. Push the CANCEL switch. The vehicle
speed indicator will turn off.
2. Tap the brake pedal. The vehicle speed indicator will turn off.
3. Turn the ProPILOT Assist switch off. Both the cruise indicator and vehicle speed
indicator will turn off.
To reset at a faster cruising speed, use one
of the following three methods:
1. Depress the accelerator pedal. When the vehicle attains the desired speed, push
and release the SET- switch.
2. Push and hold the RES+ switch. When the vehicle attains the desired speed,
release the switch.
3. Push, then quickly release the RES+ switch. Each time you do this, the set
speed will increase by about 1 mph (1.6
km/h).
To reset at a slower cruising speed, use one
of the following three methods:
1. Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the SET- switch and release it. 2. Push and hold the SET- switch. Release
the switch when the vehicle slows down
to the desired speed.
3. Push, then quickly release the SET- switch. Each time you do this, the set
speed will decrease by about 1 mph (1.6
km/h).
To resume the preset speed, push and re-
lease the RES+ switch. The vehicle will re-
sume the last set cruising speed when the
vehicle speed is over 25 mph (40 km/h).

AEB WITH PEDESTRIAN
DETECTION SYSTEM OPERATION1. Vehicle ahead detection indicator
2. AEB with Pedestrian Detection emer-gency warning indicator 3. AEB with Pedestrian Detection system
warning light
The AEB with Pedestrian Detection system
operates at speeds above approximately 3
mph (5 km/h). For the pedestrian detection
function, the AEB with Pedestrian Detec-
tion system operates at speeds between 6
– 37 mph (10 – 60 km/h).
If a risk of a forward collision with a vehicle
is detected, the AEB with Pedestrian Detec-
tion system will first provide a warning to
the driver by flashing the vehicle ahead de-
tection indicator and providing an audible
alert. In addition, the AEB with Pedestrian
Detection system applies partial braking. If
the driver applies the brakes quickly and
forcefully, but the AEB with Pedestrian De-
tection system detects that there is still the
possibility of a forward collision, the system
will automatically increase the braking
force.
If the risk of a collision becomes imminent
and the driver does not take action, the AEB
with Pedestrian Detection system issues
the second warning to the driver by flash-
ing the AEB with Pedestrian Detection
emergency warning indicator (red), provid-
ing an audible warning, and then automati-
cally applies harder braking.
LSD4076
5-124Starting and driving

If a risk of a forward impact with a pedes-
trian is detected, the AEB with Pedestrian
Detection system will provide a warning to
the driver by flashing the AEB with Pedes-
trian Detection emergency warning indica-
tor (red), provides an audible alert and the
system will apply partial braking. If the
driver applies the brakes quickly and force-
fully but the AEB with Pedestrian Detection
system detects that there is still the possi-
bility of a forward impact with a pedestrian,
the system will automatically increase the
braking force. If the risk of collision be-
comes imminent and the driver does not
take action, the AEB with Pedestrian Detec-
tion system automatically applies harder
braking.
NOTE:
The vehicle’s brake lights come on when
any braking is performed by the AEB
with Pedestrian Detection system.
Depending on vehicle speed and distance
to the vehicle or pedestrian ahead, as well
as driving and roadway conditions, the sys-
tem may help the driver avoid a forward
collision or may help mitigate the conse-
quences if a collision should be unavoid-
able. If the driver is handling the steering
wheel, accelerating or braking, the AEB withPedestrian Detection system will function
later or will not function.
The automatic braking will cease under the
following conditions:
• When the steering wheel is turned to
avoid a collision.
• When the accelerator pedal is depressed.
• When there is no longer a vehicle or a pedestrian detected ahead.
If the AEB with Pedestrian Detection sys-
tem has stopped the vehicle, the vehicle
will remain at a standstill for approximately
2 seconds before the brakes are released.
