2019 NISSAN LEAF steering

When passing another vehicle, the set
speed indicator
Bflashes when the ve-
hicle speed exceeds the set speed. The ve-
hicle ahead detection indicator turns off
when the area ahead of the vehicle is open.
When the pedal is released, the vehicle re-
turns to the previously set speed. Even
though your vehicle speed is set in the ICC
system, you can depress the accelerator
pedal when it is necessary to accelerate
your vehicle rapidly.
Cut-in detection
If a vehicle moves into your traveling lane
near your vehicle, the ICC system may in-
form the driver by flashing the vehicle
ahead detection indicator.
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 indicator and set distance indicator blink.
• You judge it necessary to maintain a safe distance.
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
increasing. • When a vehicle cuts in near your vehicle.
The warning chime will not sound when:
• Your vehicle approaches other vehicles
that are parked or moving slowly.
• The accelerator pedal is depressed, over- riding the system.NOTE:
The approach warning chime may sound
and the system display may flash when
the radar 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
radar sensor may detect these objects
when the vehicle is driven on winding,
narrow, or hilly roads or when the vehicle
is 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 conditions (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 (be-
low ICC set speed), and the turn signal is
activated to the lef t, the ICC system will
automatically start to accelerate the ve-
hicle 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 signal operates 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 ac-
celerate to the ICC system set speed. If an-
other vehicle is detected ahead, then the
vehicle will accelerate up to the following
speed of that vehicle. If the vehicle is not
steered into the lef t lane to pass, the accel-
eration will stop af ter a short time and re-
gain the set following distance. Accelera-
tion 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 follow-
ing:
• This function is only activated with the lef t turn signal and will briefly
accelerate 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 asneeded
– Never solely rely on the system
ICC system limitations
WARNING
Listed below are the system limita-
tions for the ICC system. Failure to op-
erate the vehicle in accordance with
these system limitations could result
in serious 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 sys-
tem on roads with sharp curves or
on icy roads, in heavy rain or in fog.
5-96Starting 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.

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
Starting and driving5-105

– When a sudden change in bright-ness occurs (for example, when
the vehicle enters or exits a tunnel
or is under a bridge)
– When driving on roads where the traveling lane merges or sepa-
rates or where there are tempo-
rary lane markers because of road
construction
– When there is a lane closure due to road repairs
–
When driving on a bumpy road sur-
face,suchasanunevendirtroad
– When driving on sharp curves or winding roads
– When driving on repeated uphill and downhill roads
• Do not use the Steering Assist under the following conditions because
the system will not operate properly:
–
