2020 NISSAN ALTIMA lane assist

∙ Do not place reflective materials, suchas white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane mark-
ers.
∙ 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 cam-
era unit is damaged due to an accident,
it is recommended that you visit a
NISSAN dealer.
WARNING
Failure to follow the warnings and in-
structions for proper use of the I-LI sys-
tem could result in serious injury or
death.
∙ The I-LI system will not steer the ve-hicle or prevent loss of control. 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. ∙ The I-LI system is primarily intended
for use on well-developed freeways or
highways. It may not detect the lane
markers in certain road, weather, or
driving conditions.
The I-LI system must be turned on with the
ProPILOT Assist switch (for vehicles with
ProPILOT Assist) on the steering wheel, ev-
ery time the ignition is placed in the ON
position.
The I-LI system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The I-LI system warns the driver when the
vehicle has lef t the center of the traveling
lane with an indicator and a steering wheel
vibration. The system helps assist the
driver to return the vehicle to the center of
the traveling lane by applying the brakes to
the lef t or right wheels individually (for a
short period of time).
The I-LI system monitors the lane markers
on the traveling lane using the camera unit
Alocated above the inside mirror.

I-LI SYSTEM OPERATION
The I-LI system operates above approxi-
mately 37 mph (60 km/h). When the vehicle
approaches either the lef t or the right side
of the traveling lane, the steering wheel will
vibrate and the LDW indicator (orange) on
the instrument panel will blink to alert the
driver. Then, the I-LI system will automati-
cally apply the brakes for a short period of
time to help assist the driver to return the
vehicle to the center of the traveling lane.
To turn on the I-LI system, push the ProPI-
LOT Assist switch (for vehicles with ProPI-
LOT Assist) on the steering wheel af ter
starting the engine/motor. The I-LI indica-
tor on the instrument panel will illuminate.
Push the ProPILOT Assist switch again to
turn off the I-LI system. The I-LI indicator will
turn off.

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSW system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The BSW system cannot detect all ve- hicles under all conditions.
∙ The radar sensors may not be able to detect and activate BSW when certain
objects are present such as:
– Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low height vehicles, or high ground
clearance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detec- tion zone when you accelerate
from a stop.
– A vehicle merging into an adjacent lane at a speed approximately the
same as your vehicle.
– A vehicle approaching rapidly from behind. – A vehicle which your vehicle over-
takes rapidly.
– A vehicle that passes through the detection zone quickly.
– When overtaking several vehicles in a row, the vehicles af ter the first
vehicle may not be detected if they
are traveling close together.
∙ The radar sensors’ detection zone is designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect ve-
hicles in an adjacent lane. When driv-
ing in a narrow lane, the radar sensors
may detect vehicles driving two lanes
away.
∙ The radar sensors are designed to ig- nore most stationary objects; how-
ever, objects such as guardrails, walls,
foliage and parked vehicles may oc-
casionally be detected. This is a nor-
mal operation condition.
∙ The following conditions may reduce the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
5-48Starting and driving

If it is not possible to set or the indicator
stays on, it may indicate that the system
is malfunctioning. Although the vehicle
is still drivable under normal conditions,
have the vehicle checked. It is recom-
mended that you visit a NISSAN dealer
for this service.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-drivingsystem. Within the limits of its capa-
bilities, as described in this manual, it
helps the driver with certain driving
activities.
∙ The ProPILOT Assist system is not a replacement for proper driving proce-
dures and is not designed to correct
careless, inattentive or absent-
minded driving. ProPILOT Assist will
not always steer the vehicle to keep it
in the lane. The ProPILOT Assist sys-
tem is not designed to prevent loss of
control. It is the driver’s responsibility
to stay alert, drive safely, keep the ve-
hicle in the traveling lane, and be in
control of the vehicle 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 responsi-
bility to stay alert, drive safely, keep
the vehicle in the traveling lane, and
be in control of the vehicle at all times.
∙ The ProPILOT Assist system is only an aid to assist the driver and is not a
collision warning or avoidance device.
∙ The ProPILOT Assist system is for highway use only and is not intended
for city driving. Failure to apply the
brakes or steer the vehicle when nec-
essary may result in a serious
accident.
∙ Always observe posted speed limits and do not set the speed over them.
∙ Never take your hands off the steering 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 auto-
matically cancels the ProPILOT Assist
system.
PROPILOT ASSIST (if so equipped)
5-90Starting and driving

∙ The ProPILOT Assist system does notreact to stationary and slow moving
vehicles.
∙ Always drive carefully and attentively when using the ProPILOT Assist sys-
tem. Read and understand the Own-
er’s Manual thoroughly before using
the ProPILOT Assist system. 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 Pro-
PILOT Assist system except in appro-
priate road and traffic 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
Ainstalled behind
the windshield and a radar sensor located
on the front of the vehicle
Bto measure
the distance to the vehicle ahead in the
same lane and to monitor the lane mark-
ers. If the vehicle detects a slower moving
vehicle ahead, the system will reduce 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.

∙Vehicle-to-vehicle distance control
mode: The ICC system maintains a
selected 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 se-
lected 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 standstillfor more than 3 seconds and the
vehicle ahead begins to accelerate,
push the RES+ switch or lightly de-
press 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 Brak-
ing (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, Steer-
ing Assist is not available at speeds
under 37 mph (60 km/h).
