Nissan Leaf (2019 year). Instruction - part 26

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the ICC sen-
sor may detect vehicles in a different lane,
or may temporarily not detect a vehicle
traveling ahead. This may cause the ICC
system to decelerate or accelerate the ve-
hicle.

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
distance away from the vehicle traveling
ahead.

SYSTEM TEMPORARILY
UNAVAILABLE

The following are conditions in which the
ICC system may be temporarily unavail-
able. In these instances, the ICC system
may cancel and may not be able to main-
tain 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:

• When the VDC system is turned off

• When ABS or VDC is operating

• When a vehicle ahead is not detected and

your vehicle is traveling below the speed
of 15 mph (24 km/h)

• When the system judges the vehicle is at a

standstill

• When the shift lever is not in D (Drive) or B

mode

• When the parking brake is applied

• When a wheel slips

• When the radar signal is temporarily

interrupted

Action to take

When the conditions listed above are no
longer present, turn the system off using
the ICC switch. Turn the ICC system back on
to use the system.

Condition B

When the radar sensor area of the front
bumper is covered with dirt or is ob-
structed, 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.

When driving on roads with limited road
structures or bridges (for example, long
bridges, deserts, snowfields, driving next to
long walls), the system may illuminate the
system warning light (orange) and display
the “Not Available: Front Radar Blocked”
message.

Action to take

If the warning message appears, stop the
vehicle in a safe place, place the shift 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.

Condition C

When the ICC system is not operating
properly, a chime sounds and the ICC sys-
tem warning light (orange) will come on.

5-72

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 the

vehicle at a set speed

– In heavy traffic or in traffic that

varies in speed

WARNING

Failure to follow the warnings and in-
structions for proper use of the ProPI-
LOT Assist system could result in seri-
ous injury or death.
• ProPILOT Assist is not a self-driving

system. Within the limits of its capa-
bilities, as described in this manual,
it helps the driver with certain driv-
ing activities.

• The ProPILOT Assist system is not a

replacement for proper driving pro-
cedures and is not designed to cor-
rect careless, inattentive or absent-
minded driving. ProPILOT Assist will
not always steer the vehicle to keep
it in the lane. The ProPILOT Assist
system is not designed to prevent
loss of control. It is the driver’s re-
sponsibility

stay

alert,

drive

safely, keep the vehicle in the travel-
ing lane, and be in control of the ve-
hicle at all times.

• There are limitations to the ProPILOT

Assist system capability. The ProPI-
LOT Assist system does not function
in all driving, traffic, weather, and
road conditions. It is the driver’s re-
sponsibility

stay

alert,

drive

safely, keep the vehicle in the travel-
ing lane, and be in control of the ve-
hicle at all times.

• The ProPILOT Assist system is only

an aid to assist the driver and is not a
collision warning or avoidance de-
vice.

• The ProPILOT Assist system is for

highway use only and is not in-
tended for city driving. Failure to ap-
ply the brake or steer the vehicle
when necessary may result in a seri-
ous accident.

• Always observe posted speed limits

and do not set the speed over them.

• Never take your hands off the steer-

ing wheel when driving. Always keep
your hands on the steering wheel
and drive your vehicle safely.

• Never unfasten your safety belt

when using ProPILOT Assist. Doing
so automatically cancels the ProPI-
LOT Assist system.

PROPILOT ASSIST (IF SO EQUIPPED)

Starting and driving

5-79

• The ProPILOT Assist system does not

react 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

䊊

installed be-

hind the windshield and a radar sensor lo-
cated on the front of the vehicle

䊊

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.

3. Steering-wheel-mounted control (right)

4. ProPILOT Assist switch

The ProPILOT Assist system has the follow-
ing two functions:

1. Intelligent Cruise Control (ICC)

The ICC system can be set to one of two
cruise control modes:

• Conventional (fixed speed) cruise con-

trol mode: For cruising at a preset speed

Starting and driving

5-81

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 ac-
celerator 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
the steering system to help keep your
vehicle within the traveling lane.

When there is no vehicle ahead, Steering
Assist is not available at speeds under
37 mph (60 km/h).
