2023 NISSAN ALTIMA sensor

Action to take:
If the warning message appears, stop the ve-
hicle 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 “Forward Driving Aids
temporarily disabled Front Sensor blocked
See Owner’s Manual” warning message con-
tinues to be displayed, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
Condition D
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snowfields, driving next to
long walls), the system may illuminate the
system warning light and display the “For-
ward Driving Aids Temporarily Disabled
Front Sensor Blocked See Owner’s Manual”
message.
Action to take:
When the above driving conditions no lon-
ger exist, turn the system back on.
NOTE:
If the AEB with Pedestrian Detection
system stops working, the I-FCW sys-
tem will also stop working.
SYSTEM MALFUNCTION
If the AEB with Pedestrian Detection sys-
tem malfunctions, it will be turned off auto-
matically, a chime will sound, the AEB with
Pedestrian Detection system warning light
(orange) will illuminate and the warning
message [Malfunction] will appear in the
vehicle information display.Action to take
If the warning light (orange) comes on, stop
the vehicle in a safe location, turn the en-
gine off and restart the engine. If the
warning light continues to illuminate, have
the AEB with Pedestrian Detection system
checked. It is recommended that you visit a
NISSAN dealer for this service.

SYSTEM MAINTENANCE
The radar sensor is located on the front of
the vehicle
OB. The camera is located on
the upper side of the windshield
OA.
To keep the AEB with Pedestrian Detection
system operating properly, be sure to ob-
serve the following:
• Always keep the sensor areas of the front bumper and windshield clean.
• Do not strike or damage the areas around the sensors (e.g., bumper,
windshield). • Do not cover or attach stickers, or install
any accessory near the sensors. This
could block sensor signals and/or cause
failure or malfunction.
• Do not attach metallic objects near the radar sensor (brush guard, etc.). This
could cause failure or malfunction.
• Do not place reflective materials, such as white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit's
detection capability.
• Do not alter, remove or paint the front bumper. Before customizing or restoring
the front bumper, it is recommended that
you visit a NISSAN dealer.

FCC Notice
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user’s authority
to operate the equipment.WARNING
Failure to follow the warnings and in-
structions for proper use of the I-FCW
system could result in serious injury or
death.
• The I-FCW system can help warn the
driver before a collision occurs but
will not avoid a collision. It is the driv-
er’s responsibility to stay alert, drive
safely and be in control of the vehicle
at all times.
The I-FCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle
ahead in the same lane. The I-FCW system uses a radar sensor
O1
located on the front of the vehicle to mea-
sure the distance to the vehicle ahead in
the same lane.

WARNING (I-FCW)
Starting and driving5-147

WARNING
Listed below are the system limitations
for the I-FCW system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
• The I-FCW system cannot detect all
vehicles under all conditions. •
The radar sensor does not detect the
following objects:
– Pedestrians, animals or obstacles
in the roadway
– Oncoming vehicles
– Crossing vehicles
• (Illustration A) The I-FCW system
does not function when a vehicle
ahead is a narrow vehicle, such as a
motorcycle. •
The radar sensor may not detect a
vehicle ahead in the following
conditions:
– Snow or heavy rain
– Dirt, ice, snow or other material
covering the radar sensor.
– Interference by other radar
sources.
– Snow or road spray from traveling
vehicles.
– Driving in a tunnel
– (Illustration B) When the vehicle
ahead is being towed.

–(Illustration C) When the distance
to the vehicle ahead is too close,
the beam of the radar sensor is
obstructed.
– (Illustration D) When driving on a
steep downhill slope or roads with
sharp curves.
• The system is designed to automati-
cally check the sensor’s functionality,
within certain limitations. The sys-
tem may not detect some forms of
obstruction of the sensor area such
as ice, snow, stickers, etc. In these
cases, the system may not be able to
warn the driver properly. Be sure that
you check, clean and clear the sensor
area regularly.
• Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

SYSTEM TEMPORARILY
UNAVAILABLE
Condition A
When the radar sensor picks up interfer-
ence from another radar source, making it
impossible to detect a vehicle ahead, the
I-FCW system is automatically turned off.

warning light (orange) will illuminate.
Action to take
When the above conditions no longer exist,
the I-FCW system will resume
automatically.
Condition B
When there is inclement weather (rain, fog,
snow, etc.) blocking the front radar sensor,
the I-FCW system will automatically be
canceled, the chime will sound and the
“Forward Driving Aids temporarily disabled
