lane assist NISSAN LEAF 2019 Owner´s Manual

• The ProPILOT Assist system does notreact to stationary and slow moving
vehicles.
• Always drive carefully and atten- tively when using the ProPILOT As-
sist system. Read and understand
the Owner’s Manual thoroughly be-
fore using the ProPILOT Assist sys-
tem. To avoid serious injury or death,
do not rely on the system to prevent
accidents or to control the vehicle’s
speed in emergency situations. Do
not use the ProPILOT Assist system
except in appropriate road and traf-
fic conditions. The ProPILOT Assist system is intended to
enhance the operation of the vehicle when
following a vehicle traveling in the same
lane and direction.
The ProPILOT Assist system uses a multi-
sensing front camera unit
Ainstalled be-
hind the windshield and a radar sensor lo-
cated on the front of the vehicle
Bto
measure the distance to the vehicle ahead
in the same lane and to monitor the lane
markers. If the vehicle detects a slower
moving vehicle ahead, the system will re-
duce the vehicle speed so that your vehicle
follows the vehicle in front at the selected distance. The system will also help keep the
vehicle centered in the traveling lane when
clear lane markings are detected.
Starting and driving5-81

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 se-
lected 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 selected
by the driver between 20 to 90 mph
(32 to 144 km/h). When the vehicle
ahead slows to a stop, your vehicle
gradually decelerates to a standstill.
When the vehicle is stopped, the ICC
system maintains braking force to keep
your vehicle stopped.
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
accelerator 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
Braking (AEB) setting is turned off by
the driver using the “Settings” menu in
the vehicle information display, AEB
will be automatically turned on when
ICC is used.
2. Steering Assist
The Steering Assist function controls

INTELLIGENT CRUISE CONTROL
(ICC) (FOR VEHICLES WITH
PROPILOT ASSIST)
WARNING
Failure to follow the warnings and in-
structions for proper use of the ICC
system could result in serious injury or
death.
• The ICC system is only an aid to as- sist the driver and is not a collision
warning or avoidance device. It is
recommended for highway use only
and it is not intended for city driving.
It is the driver’s responsibility to stay
alert, drive safely, and be in control
of the vehicle at all times.
• There are limitations to the ICC sys- tem capability. The ICC system does
not function in all driving, traffic,
weather, and road conditions. 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.
• Always observe posted speed limits and do not set the speed over them.
Starting and driving5-91

• 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)

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

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
