Esu NISSAN ALTIMA 2023 Repair Manual

• 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.

WARNING
Failure to follow the warnings and in-
structions for proper use of the BSW
system could result in serious injury or
death.
• The BSW system is not a replacement
for proper driving procedures and is
not designed to prevent contact with
vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the di-
rection your vehicle will move to en-
sure it is safe to change lanes. Never
rely solely on the BSW system.
The BSW system helps alert the driver of
other vehicles in adjacent lanes when
changing lanes. The BSW system uses radar sensors
O1
installed near the rear bumper to detect
other vehicles in an adjacent lane.
The radar sensors can detect vehicles on
either side of your vehicle within the detec-
tion zone shown as illustrated. This detec-
tion zone starts from the outside mirror of
your vehicle and extends approximately 10
f t (3.0 m) behind the rear bumper, and ap-
proximately 10 f t (3.0 m) sideways.

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSW system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
• The BSW system cannot detect all ve-
hicles under all conditions.
• The radar sensors may not be able to
detect and activate BSW when cer-
tain objects are present such as:
– Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low
height vehicles, or high ground
clearance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detec-
tion zone when you accelerate
from a stop.
– A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle.
– A vehicle approaching rapidly
from behind.
– A vehicle which your vehicle over-
takes rapidly. –
A vehicle that passes through the
detection zone quickly.
– When overtaking several vehicles
in a row, the vehicles af ter the first
vehicle may not be detected if
they are traveling close together.
• The radar sensors’ detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect ve-
hicles in an adjacent lane. When driv-
ing in a narrow lane, the radar sen-
sors may detect vehicles driving two
lanes away.
• The radar sensors are designed to ig-
nore most stationary objects; how-
ever, objects such as guardrails,
walls, foliage and parked vehicles
may occasionally be detected. This is
a normal operation condition.
• The following conditions may reduce
the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on
the vehicle •
Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar to
detect other vehicles.
• Excessive noise (for example, audio
system volume, open vehicle win-
dow) will interfere with the chime
sound, and it may not be heard.

WARNING
Failure to follow the warnings and in-
structions for proper use of the RCTA
could result in serious injury or death.
• The RCTA system is not a replace-
ment for proper driving procedures
and is not designed to prevent con-
tact with vehicles or objects. When
backing out of a parking space, al-
ways use the side and rear mirrors
and turn and look in the direction
your vehicle will move. Never rely
solely on the RCTA system.
The RCTA system will assist you when
backing out from a parking space. When
the vehicle is in reverse, the system is de-
signed to detect other vehicles approach-
ing from the right or lef t of the vehicle. If the
system detects cross traffic, it will alert you.
