2023 NISSAN ALTIMA steering wheel

The LDW system provides a lane departure
warning function when the vehicle is driven
at speeds of approximately 37 mph (60
km/h) and above and the lane markings
are clear. When the vehicle approaches ei-
ther the lef t or the right side of the traveling
lane, the steering wheel will vibrate and the
LDW indicator on the instrument panel will
blink to alert the driver.
The warning function will stop when the
vehicle returns inside of the lane markers.

• Do not place reflective materials, such aswhite 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 recom-
mended 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
OAlocated above the inside mirror.

I-LI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the I-LI system. Failure to follow the
warnings and instructions for proper
use of the I-LI system could result in
serious injury or death.
• The I-LI system may activate if you
change lanes without first activating
your turn signal or, for example, if a
construction zone directs traffic to
cross an existing lane marker. If this
occurs you may need to apply correc-
tive steering to complete your lane
change.
• Because the I-LI may not activate un-
der the road, weather, and lane
marker conditions described in this
section, it may not activate every
time your vehicle begins to leave its
lane and you will need to apply cor-
rective steering.
• When the I-LI system is operating,
avoid excessive or sudden steering
maneuvers. Otherwise, you could
lose control of the vehicle. •
The I-LI system will not operate at
speeds below approximately 37 mph
(60 km/h) or if it cannot detect lane
markers.
• Do not use the I-LI system under the
following conditions as it may not
function properly:
– During bad weather (rain, fog,
snow, etc.).
– When driving on slippery roads,
such as on ice or snow.
– When driving on winding or un-
even roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshif t or
temporary lane.
– When driving on roads where the
lane width is too narrow.
– When driving without normal tire
conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-
standard wheels).
– When the vehicle is equipped with
nonoriginal brake parts or sus-
pension parts.
– When you are towing a trailer or
other vehicle. –
On roads where there are multiple
parallel lane markers; lane mark-
ers that are faded or not painted
clearly; yellow painted lane mark-
ers; non-standard lane markers;
or lane markers covered with wa-
ter, dirt, snow, etc.
– On roads where discontinued lane
markers are still detectable.
– On roads where there are sharp
curves.
– On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs. (The I-LI system
could detect these items as lane
markers.)
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
marker.
– When traveling close to the ve-
hicle in front of you, which ob-
structs the lane camera unit de-
tection range.
Starting and driving5-43

–When rain, snow or dirt adheres to
the windshield in front of the lane
camera unit.
– When the headlights are not
bright due to dirt on the lens or if
the aiming is not adjusted
properly.
– When strong light enters the lane
camera unit. (For example, the
light directly shines on the front of
the vehicle at sunrise or sunset.)
– When a sudden change in bright-
ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
While the I-LI system is operating, you may
hear a sound of brake operation. This is
normal and indicates that the I-LI system is
operating properly.SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the I-LI
system are not designed to work under the
following conditions:
• When you operate the lane change signal and change the traveling lanes in the di-
rection of the signal. (The I-LI system will
be deactivated for approximately 2 sec-
onds af ter the lane change signal is
turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the warning and assist func-
tions will resume.
Condition B:
The assist function of the I-LI system is not
designed to work under the following con-
ditions (warning is still functional):
• When the brake pedal is depressed.
• When the steering wheel is turned as far as necessary for the vehicle to change
lanes.
• When the vehicle is accelerated during I-LI system operation. • When the Intelligent Cruise Control (ICC)
approach warning occurs.
• When the hazard warning flashers are operated.
• When driving on a curve at high speed.
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the I-LI system application of
the brakes will resume.
Condition C:
If the following messages appear in the
vehicle information display, the I-LI system
will be turned off automatically.
• “Not Available Poor Road Conditions”: When the VDC system (except Traction
Control System [TCS] function) or ABS
operates.
• “Currently not available”: When the VDC system is turned off.
Action to take:
When the above conditions no longer exist,
turn off the I-LI system. Push the ProPILOT
Assist switch (for vehicles with ProPILOT
Assist) on the steering wheel again to turn
the I-LI system back on.
5-44Starting and driving

The vehicle may not maintain the set
speed on winding or hilly roads. If this oc-
curs, you will have to manually control the
vehicle speed.
Normally when controlling the distance to
a vehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is re-
quired for a lane change. Depress the brake
pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when us-
ing the ICC system.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE SWITCHES
The system is operated by the ICC switch
and four control switches, all mounted on
the steering wheel.
1.CANCEL switch:
Deactivates the system without erasing
the set speed.
2. RES+ switch:
Resumes set speed or increases speed
incrementally. 3.
DISTANCE
switch:
Changes the vehicle’s following
distance: • Long
• Middle
• Short
4. ICC switch:
Master switch to activate the system.
5. SET- switch:
Sets desired cruise speed or reduces
speed incrementally.

5-76Starting and driving

NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC 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
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
entering or exiting a curve. In these
cases you will have to manually control
the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed:
• When the vehicle ahead is not detectedand your vehicle is traveling below the
speed of 15 mph (25 km/h)
• When the system judges the vehicle is at a standstill • When the shif t lever is not in the D (Drive)
position, Manual mode or L (Low) range.
• When the parking brake system is applied
• When the VDC system is turned off
• When VDC operates
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
• When a wheel slips
• When the radar signal is temporarily interrupted
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE 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
system 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 over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the
brake pedal, depending on the dis-
tance to the vehicle ahead and the
surrounding circumstances in order
to maintain a safe distance between
vehicles.
• If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
5-82Starting and driving

• When the parking brake is applied
• When the VDC operates (including thetraction control system)
• When a wheel slips
When the system is not operating properly,
the chime sounds and the color of the
cruise indicator will change to orange.
Action to take
If the color of the cruise indicator changes
to orange, stop the vehicle in a safe place
and place the shif t lever in the P (Park) po-
sition. Turn the engine off, restart the en-
gine, resume driving, and then perform the
setting again.
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-driving
system. 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 pro-
cedures and is not designed to cor-
rect 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
vehicle 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 re-
sponsibility 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 steer-
ing 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
automatically cancels the ProPILOT
Assist system.
