2019 NISSAN LEAF Owner´s Manual

• Driving on a steep downhill slope or roadswith 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 your vehicle is towing a trailer, etc.
• 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.
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 distance
away from the vehicle traveling ahead.
The ICC system (with ProPILOT Assist) uses
a multi-sensing front camera. The follow-
ing are some conditions in which the cam-
era may not properly detect a vehicle and
detection of a vehicle ahead may be de-
layed:
• Poor visibility (conditions such as rain,
snow, fog, dust storms, sandstorms, and
road spray from other vehicles)
• The camera area of the windshield is fogged up or covered with dirt, water
drops, ice, snow, etc.
• Strong light (for example, sunlight or high beams from oncoming vehicles) enters
the front camera
• A sudden change in brightness occurs (for example, when the vehicle enters or exits
a tunnel or shaded area or lightning
flashes)
5-98Starting 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
sounding the chime unexpectedly. You will
have to manually control the proper dis-
tance 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.
Starting and driving5-99

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 andyour 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 ap- plies 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. • When the radar signal is temporarily
interrupted.
Action to take:
When the conditions listed above are no lon-
ger present, turn the system off using the
ProPILOT Assist switch. Turn the ProPILOT
Assist system back on to use the system.
NOTE:
When the ICC system is canceled un-
der the following conditions at a
standstill, the electronic parking brake
is automatically activated:
• Any door is open.
• The driver’s seat belt is not fastened.
• 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) po-
sition or B mode.
• The VDC system is turned off.
• When distance measurement becomes
impaired due to adhesion of dirt or ob-
struction to the sensor.
• When the radar signal is temporarily in-
terrupted. Condition B
When the radar sensor of the front bumper
is covered with dirt or is obstructed, the ICC
system will automatically 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.
5-100Starting and driving

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 “Not
Available: Front Radar Blocked” 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 system
again. If it is not possible to set the ICC sys-
tem 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.
ICC sensor maintenance
The radar sensor is 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 aroundthe 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.
The camera sensor is located above the
inside mirror. To keep the proper operation of the sys-
tems and prevent a system malfunction,
be sure to observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including trans-
parent material) or install an accessory
near the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit a
NISSAN certified LEAF dealer.

STEERING ASSIST
WARNING
Failure to follow the warnings and in-
structions for proper use of the Steer-
ing Assist could result in serious injury
or death.
• The Steering Assist is not a replace- ment for proper driving procedures
and is not designed to correct care-
less, inattentive or absent-minded
driving. The Steering Assist will not
always steer the vehicle to keep it in
the lane. It is not designed to prevent
loss of control. It is the driver’s re-
sponsibility to stay alert, drive
safely, keep the vehicle in the travel-
ing lane, and be in control of the ve-
hicle at all times.
• As there is a performance limit to the Steering Assist’s capability, never
rely solely on the system. The Steer-
ing Assist does not function in all
driving, traffic, weather, and road
conditions. Always drive safely, pay
attention to the operation of the ve-
hicle, and manually control your ve-
hicle appropriately. • The Steering Assist is intended for
use on well-developed freeways or
highways with gentle (moderate)
curves. To avoid risk of an accident,
do not use this system on local or
non-highway roads.
• The Steering Assist only steers the vehicle to maintain its position in the
center of a lane. The vehicle will not
steer to avoid objects in the road in
front of the vehicle or to avoid a ve-
hicle moving into your lane.
• 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. Never take
your hands off the steering wheel
when driving. Always keep your
hands on the steering wheel and
drive your vehicle safely.
• Always drive carefully and atten- tively when using the Steering As-
sist. Read and understand the Own-
er’s Manual thoroughly before using
the Steering Assist. To avoid serious
injury or death, do not rely on the
system to prevent accidents or to
control the vehicle’s speed in emer-
gency situations. Do not use the
Steering Assist except in appropri-
ate road and traffic conditions.
Steering Assist operation
The Steering Assist controls the steering
system to help keep your vehicle near the
center of the lane when driving. The Steer-
ing Assist is combined with the Intelligent
Cruise Control (ICC) system. For additional
information, refer to “Intelligent Cruise Con-
trol (ICC) (with ProPILOT Assist)” in this sec-
tion.
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearly
detected.
• A vehicle ahead is detected (when the ve- hicle is driven at speeds under 37 mph
[60 km/h]).
• The driver grips the steering wheel.
• The vehicle is driven at the center of the lane.
• The turn signals are not operated.
• The windshield wiper is not operated in the high (HI) speed operation (the steering
assist function is disabled af ter the wiper
operates for approximately 10 seconds).

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.
Starting and driving5-103

Hands on detection
When the Steering Assist is activated, it
monitors the driver’s steering wheel opera-
tion.
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
1
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.
5-104Starting and driving

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 se-
rious personal injury or death.
NOTE:
If the driver lightly touches (instead of
firmly grips) the steering wheel, the
steering torque sensor may not detect
the driver’s hand(s) on the wheel and a
sequence of warnings may occur.
When the driver holds and operates
the steering wheel again, the warn-
ings turn off.
Steering Assist limitations
WARNING
• In the following situations, the cam- era may not detect lane markers
correctly or may detect lane mark-
ers incorrectly and the Steering As-
sist may not operate properly:
– When driving on roads wherethere are multiple parallel lane
markers, lane markers that are
faded or not painted clearly, non-
standard lane markers, or lane
markers covered with water, dirt,
snow, etc.
– When driving on roads with dis- continued lane markers
– When driving on roads with a wid- ening or narrowing lane width
– When driving on roads where there are multiple lanes or unclear
lane markers due to road con-
struction
– When driving on roads where there are sharply contrasting ob-
jects, such as shadows, snow,
water, wheel ruts, seams, or lines
remaining af ter road repairs (the Steering Assist could detect these
items as lane markers)
– When driving on roads where the traveling lane merges or sepa-
rates
• Do not use the Steering Assist under the following conditions because
the system may not properly detect
lane markers. Doing so could cause a
loss of vehicle control and result in
an accident.
– During bad weather (rain, fog,snow, dust, etc.)
– When rain, snow, sand, etc., is thrown up by the wheels of other
vehicles
– When dirt, oil, ice, snow, water, or another object adheres to the
camera unit
– When the lens of the camera unit is foggy
– When strong light (for example, sunlight or high beams from on-
coming vehicles) shines on the
camera
– When the headlights are not bright due to dirt on the lens or
the headlights are off in tunnels or
in darkness
