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.

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.

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
Page 465 of 610
– 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:
–
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 withnon-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
– When towing a trailer or other ve- hicle
• Excessive noise will interfere with the warning chime sound, and the
beep may not be heard.
• For the ProPILOT Assist system to operate 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 de-
signed 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.
Steering Assist temporary
standby
Automatic standby due to driving opera-
tion:
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)
5-106Starting and driving
Page 466 of 610
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:
• When unusual lane markers appear in thetraveling lane or when the lane marker
cannot be correctly detected for some
time due to certain conditions (for ex-
ample, a snow rut, the reflection of light on
a rainy day, the presence of several un-
clear lane markers)
• When the windshield wiper operates in the high (HI) speed operation (the Steering
Assist is disabled when the wiper oper-
ates for more than approximately
10 seconds)
Action to take:
Turn the ICC system off using the CANCEL
switch. When the conditions listed above
are no longer present, turn the ICC system
on again.
Steering Assist malfunction
When the system malfunctions, it turns off
automatically. The Steering Assist status
warning illuminates (orange). A chime may
sound depending on the situation.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the EV
system off, restart the EV system, resume driv-
ing, and set the Intelligent Cruise Control sys-
tem again. If the warning (orange) continues to
illuminate, the Steering Assist is malfunction-
ing. Although the vehicle is still drivable under
normal conditions, have the system checked.
It is recommended that you visit a NISSAN cer-
tified LEAF dealer for this service.
Steering Assist maintenance
The camera sensor is located above the
inside mirror.
To keep the proper operation of the system
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.

WARNING
• In the conventional (fixed speed) cruise control mode, a warning
chime does not sound to warn you if
you are too close to the vehicle
ahead, as neither the presence of
the vehicle ahead nor the vehicle-to-
vehicle distance is detected.
• Pay special attention to the distance between your vehicle and the ve-
hicle ahead of you or a collision
could occur.
• Always confirm the setting in the ICC system display.
• Do not use the conventional (fixed speed) cruise control mode when
driving under the following condi-
tions:
– When it is not possible to keep thevehicle at a set speed
– In heavy traffic or in traffic that varies in speed
