2023 NISSAN ALTIMA Owners Manual

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 distance
away from the vehicle traveling ahead.
The ICC system (with ProPILOT Assist) uses
a multi-sensing front camera. The follow-
ing are some conditions in which the cam-
era may not properly detect a vehicle and
detection of a vehicle ahead may be de-
layed:
• Poor visibility (conditions such as rain,snow, fog, dust storms, sandstorms, and
road spray from other vehicles)
• The camera area of the windshield is fogged up or covered with dirt, water
drops, ice, snow, etc.
• Strong light (for example, sunlight or high beams from oncoming vehicles) enters
the front camera
• A sudden change in brightness occurs (for example, when the vehicle enters or
exits a tunnel or shaded area or lightning
flashes)

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 sound-
ing 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 not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.Condition A

a malfunction. Although the normal driving
can be continued, the ICC system shouldbe inspected. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the ICC system is temporarily unavail-
able, the conventional cruise control
mode may still be used. For additional
information, please see “Conventional
(fixed speed) cruise control mode”
(P. 5-123).
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 of the front
bumper/emblem 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 markers.
• 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
always steer the vehicle to keep it in
the lane. It is not designed to prevent
loss of control. It is the driver’s re-
sponsibility 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 Steer-
ing Assist does not function in all
driving, traffic, weather, and road
conditions. Always drive safely, pay
attention to the operation of the ve-
hicle, and manually control your ve-
hicle appropriately. •
The Steering Assist is intended for
use on well-developed freeways or
highways with gentle (moderate)
curves. To avoid risk of an accident,
do not use this system on local or
non-highway roads.
• The Steering Assist only steers the
vehicle to maintain its position in the
center of a lane. The vehicle will not
steer to avoid objects in the road in
front of the vehicle or to avoid a ve-
hicle moving into your lane.
• 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. Never take
your hands off the steering wheel
when driving. Always keep your
hands on the steering wheel and
drive your vehicle safely. •
Always drive carefully and atten-
tively when using the Steering Assist.
Read and understand the Owner’s
Manual thoroughly before using the
Steering Assist. To avoid serious in-
jury or death, do not rely on the sys-
tem to prevent accidents or to con-
trol the vehicle’s speed in emergency
situations. Do not use the Steering
Assist except in appropriate road and
traffic conditions.
Steering Assist operation
The Steering Assist controls the steering
system to help keep your vehicle near the
center of the lane when driving. The Steer-
ing Assist is combined with the Intelligent
Cruise Control (ICC) system. For additional
information, see “Intelligent Cruise Control
(ICC) (for vehicles with ProPILOT Assist)”
(P. 5-106).
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearly detected.
• A vehicle ahead is detected (when the vehicle is driven at speeds under 37 mph
[60 km/h]).
Starting and driving5-117

• The driver grips the steering wheel.
• The vehicle is driven at the center of thelane.
• The turn signals are not operated.
• The windshield wiper is not operated in the high (HI) speed operation (the Steer-
ing Assist function is disabled af ter the
wiper operates for approximately 10
seconds).

Intelligent Lane Intervention (I-LI)
When a curve or strong cross wind exceeds
the capabilities of the Steering Assist and
your vehicle approaches either the lef t or
the right side of the traveling lane, the I-LI
indicator (orange) on the instrument panel
flashes to alert the driver. Then, the I-LI sys-
tem automatically applies the brakes for a
short period of time to help assist the
driver to return the vehicle to the center of
the traveling lane. This action is in addition
to any Steering Assist actions.
Hands on detectionWhen the Steering Assist is activated, it
monitors the driver’s steering wheel
operation.
LSD3236
Starting and driving5-119

If the steering wheel is not operated or the
driver takes his/her hands off the steering
wheel for a period of time, the warning
O1
appears in the vehicle information display.
If the driver does not operate the steering
wheel af ter the warning has been dis-
played, an audible alert sounds and the
warning flashes in the vehicle information
display, followed by a quick brake applica-
tion to request the driver to take control of
the vehicle again.
If the driver still does not respond, the Pro-
PILOT Assist turns on the hazard flasher
and slows the vehicle to a complete stop.
The driver can cancel the deceleration at
any time by steering, braking, accelerating,
or operating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for
hands-free driving. Always keep your
hands on the steering wheel and drive
your vehicle safely. Failure to do so
could cause a collision resulting in seri-
ous personal injury or death.
NOTE:
If the driver lightly touches (instead of
firmly grips) the steering wheel, the
steering torque sensor may not detect
the driver’s hand(s) on the wheel and a
sequence of warnings may occur. When
the driver holds and operates the steer-
ing wheel again, the warnings turn off.
Steering Assist limitations
WARNING
• In the following situations, the cam-
era may not detect lane markers cor-
rectly or may detect lane markers in-
correctly and the Steering Assist may
not operate properly:
– When driving on roads where
there are multiple parallel lane
markers, lane markers that are
faded or not painted clearly, non-
standard lane markers, or lane
markers covered with water, dirt,
snow, etc.
– When driving on roads with dis-
continued lane markers
– When driving on roads with a wid-
ening or narrowing lane width –
When driving on roads where
there are multiple lanes or unclear
lane markers due to road
construction
– When driving on roads where
there are sharply contrasting ob-
jects, such as shadows, snow, wa-
ter, wheel ruts, seams, or lines re-
maining af ter road repairs (the
Steering Assist could detect these
items as lane markers)
– When driving on roads where the
traveling lane merges or
separates
• Do not use the Steering Assist under
the following conditions because the
system may not properly detect lane
markers. Doing so could cause a loss
of vehicle control and result in an ac-
cident.
– During bad weather (rain, fog,
snow, dust, etc.)
– When rain, snow, sand, etc., is
thrown up by the wheels of other
vehicles
– When dirt, oil, ice, snow, water, or
another object adheres to the
camera unit
