2020 NISSAN ALTIMA maintenance

Malfunction
If the BSW system malfunctions, it will turn
off automatically. The system malfunction
warning message with the BSW indicator
(orange) will appear in the vehicle informa-
tion display.
NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the mes-
sage continues to appear, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
SYSTEM MAINTENANCE
The two radar sensors1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the ra-
dar sensors clean.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the radar sensors.
Do not strike or damage the area around
the radar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the radar sensors is damaged due to a
collision.

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.

ICC sensor maintenance
The radar sensor is 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 restoring the front
bumper, it is recommended that you visit a
NISSAN dealer.
The camera sensor is located above the
inside mirror. To keep the proper operation of the sys-
tems 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 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 camera unit is damaged due to an
accident, it is recommended that you visit a
NISSAN dealer.
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 al-
ways steer the vehicle to keep it in the
lane. It is not designed to prevent loss
of control. It is the driver’s responsibil-
ity to stay alert, drive safely, keep the
vehicle in the traveling lane, and be in
control of the vehicle at all times.
∙ As there is a performance limit to the Steering Assist’s capability, never rely
solely on the system. The Steering As-
sist does not function in all driving,
traffic, weather, and road conditions.
Always drive safely, pay attention to
the operation of the vehicle, and
manually control your vehicle
appropriately.
∙ The Steering Assist is intended for use on well-developed freeways or high-
ways with gentle (moderate) curves.
To avoid risk of an accident, do not use
this system on local or non-highway
roads.

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 the traveling lane or when the lane
marker cannot be correctly detected
for some time due to certain conditions
(for example, a snow rut, the reflection
of light on a rainy day, the presence of
several unclear lane markers)
∙ When the windshield wiper operates in the high (HI) speed operation (the Steer-
ing Assist is disabled when the wiper
operates 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 en-
gine off, restart the engine, resume driving,
and set the Intelligent Cruise Control sys-
tem again. If the warning (orange) contin-
ues to illuminate, the Steering Assist is mal-
functioning. Although the vehicle is still
drivable under normal conditions, have the
system checked. It is recommended that
you visit a NISSAN dealer for this service.
