2020 NISSAN ALTIMA sensor

– Interference by other radarsources
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the follow-
ing objects: ∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane
The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system
may not maintain the selected distance. The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly:
∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ 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 sensor’s operation within
the limitations of the system.
When the sensor is covered with dirt or is
obstructed, the system will automatically
be canceled. If the sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them.
In these instances, the vehicle-to-vehicle
distance control mode may not cancel and
may not be able to maintain the selected
following distance from the vehicle ahead.
Be sure to check and clean the sensor
regularly. The detection zone of the radar sensor is
limited. A vehicle ahead must be in the de-
tection zone for the vehicle-to-vehicle dis-
tance detection mode to maintain the se-
lected 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 centerline
of the lane. A vehicle that is entering 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 dis-
tance away from vehicle traveling ahead.

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
distance away from the vehicle traveling
ahead.

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.
Action to take
If the warning message appears, stop the
vehicle in a safe place, place the shif t lever
in the P (Park) position, and turn the engine
off. When the radar signal is temporarily
interrupted, clean the sensor area of the
front bumper and restart the engine. If the
“Not Available: Front Radar Blocked” warn-
ing message continues to be displayed,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.When driving on roads with limited road
structures (for example, long bridges, des-
erts, snow fields, driving next to long walls),
the system may illuminate the system
warning light and display the “Not Available:
Front Radar Blocked” message.
Action to take
When the above driving conditions no lon-
ger exist, turn the system back on.
Condition C
When the ICC system is not operating
properly, a chime sounds and the ICC sys-
tem warning light (orange) will come on.

Action to take
If the warning light comes on, park the ve-
hicle in a safe place. Turn the engine off,
restart the engine, resume driving and set
the ICC system again.
If it is not possible to set the system or
the indicator stays on, it may indicate
that the system is malfunctioning. Al-
though the vehicle is still drivable under
normal conditions, have the vehicle
checked. It is recommended that you
visit a NISSAN dealer for this service.SYSTEM MAINTENANCE
The sensor for the ICC system1is located
on the front of the vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
∙ Always keep the sensor area clean.
∙ Do not strike or damage the areas around the sensor.
∙ Do not attach a sticker (including trans- parent material) or install an accessory
near the sensor. This could cause failure
or malfunction. ∙ Do not attach metallic objects near the
sensor area (brush guard, etc.). This
could cause failure or malfunction.
∙ Do not alter, remove, or paint the front bumper. Before customizing or restor-
ing the front bumper, it is recom-
mended that you visit a NISSAN dealer.

∙ 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.

When passing another vehicle, the set
speed indicator
Aflashes 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 ve-
hicles 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, overriding 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, nar-
row, 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.LSD3234

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
37 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 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 accelerate to the
ICC system set speed. If another vehicle is
detected ahead, then the vehicle will accel-
erate up to the following speed of that ve-
hicle. If the vehicle is not steered into the
lef t lane to pass, the acceleration will stop
af ter a short time and regain the set follow-
ing distance. Acceleration 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 following:
∙ This function is only activated withthe lef t turn signal and will briefly ac-
celerate 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 ve- hicle, the adjacent lane is clear before
initiating the pass. Sudden changes in
traffic may occur while passing- al-
ways manually steer or brake as
needed- never solely rely on the
system.
ICC system limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous 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 sys-
tem should be used in evenly flowing
traffic. Do not use the system on roads
with sharp curves or on icy roads, in
heavy rain or in fog.
∙ As there is a performance limit to the distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absentminded driving or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, de-
pending on the distance to the vehicle
ahead and the surrounding circum-
stances in order to maintain a safe
distance between vehicles.
∙ When the ICC system automatically brings the car to a stop, your vehicle
can automatically accelerate if the ve-
hicle is stopped for less than approxi-
mately 3 seconds. Be prepared to stop
your vehicle if necessary.

∙ Always pay attention to the operationof the vehicle and be ready to manu-
ally control the proper following dis-
tance. The ICC system may not be able
to maintain the selected distance be-
tween vehicles (following distance) or
selected vehicle speed under some
circumstances.
∙ The system may not detect the ve- hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system under
the following conditions:
– On roads with heavy, high-speed traffic or sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance
sensor
– On steep downhill roads (the ve- hicle may go beyond the set ve-
hicle speed and frequent braking
may result in overheating the
brakes) – On repeated uphill and downhill
roads
– When traffic conditions make it dif- ficult to keep a proper distance be-
tween vehicles because of fre-
quent acceleration or deceleration
– Interference by other radar sources.
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The ICC system will not detect the following
objects: ∙ Stationary or slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane The following are some conditions in which
the radar sensor cannot properly detect a
vehicle ahead and the system may not op-
erate properly:
∙ When the sensor detection is reduced (conditions such as rain, snow, fog, dust
storms, sandstorms, and road spray
from other vehicles)
∙ Driving on a steep downhill slope or roads with sharp curves
∙ Driving on a bumpy road surface, such as an uneven dirt road
∙ If dirt, ice, snow or other material is cov- ering 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.
