ESP NISSAN ALTIMA 2023 Service Manual

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

lease the RES+ switch. The vehicle will re-
sume the last set cruising speed when the
vehicle speed is over 25 mph (40 km/h).WARNING
Failure to follow the warnings and in-
structions for proper use of the RAB
system could result in serious injury or
death.
• The RAB system is a supplemental
aid to the driver. It is not a replace-
ment for proper driving procedures.
Always use the side and rear mirrors
and turn and look in the direction you
will move before and while backing
up. Never rely solely on the RAB sys-
tem. It is the driver’s responsibility to
stay alert, drive safely, and be in con-
trol of the vehicle at all times.
• There is a limitation to the RAB sys-
tem capability. The RAB system is not
effective in all situations.
• Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may af-
fect the function of the system; this
may include reduced performance or
a false activation.
The RAB system can assist the driver when
the vehicle is backing up and approaching
objects directly behind the vehicle. The RAB system detects obstacles behind
the vehicle using the parking sensors
O1
located on the rear bumper.
NOTE:
You can temporarily cancel the sonar
function in the vehicle, but the RAB sys-
tem will continue to operate. For addi-
tional information, please see “Rear So-
nar System (RSS)” (P. 5-179).

WARNING
Failure to follow the warnings and in-
structions for proper use of the I-DA
system could result in serious injury or
death.
• The I–DA system is only a warning to
inform the driver of a potential lack
of driver attention or drowsiness. It
will not steer the vehicle or prevent
loss of control.
• The I–DA system does not detect and
provide an alert of the driver’s lack of
attention or fatigue in every
situation.
• It is the driver’s responsibility to:
– stay alert,
– drive safely,
– keep the vehicle in the traveling lane,
– be in control of the vehicle at all times,
– avoid driving when tired,
– avoid distractions (texting, etc.). The I–DA system helps alert the driver if the
system detects a lack of attention or driv-
ing fatigue.
The system monitors driving style and
steering behavior over a period of time,
and it detects changes from the normal
pattern. If the system detects that driver
attention is decreasing over a period of
time, the system uses audible and visual
warnings to suggest that the driver take a
break.

CURB
OC:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the ignition switch in the LOCK position.
WARNING
• If the engine is not running or is
turned off while driving, the power
assist for the steering will not work.
Steering will be harder to operate.
• When the power steering warning
light illuminates with the engine run-
ning, there will be no power assist for
the steering. You will still have control
of the vehicle, but the steering will be
much harder to operate. Have the
power steering system checked. It is
recommended that you visit a
NISSAN dealer for this service.
The power steering system is designed to
provide power assistance while driving to
operate the steering wheel with light force.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and protect it from getting
damaged. While the power assist is re-
duced, steering wheel operation will be-
come heavy. If the steering wheel opera-
tion is still performed, the power steering
may stop and the power steering warning
light will illuminate. In a safe location, stop the engine and place the ignition switch in
the OFF position. The temperature of the
power steering system will go down af ter a
period of time and the power assist level
will return to normal af ter starting the en-
gine. The power steering warning light will
go off. Avoid repeating such steering wheel
operations that could cause the power
steering system to overheat.
You may hear a noise from the front of the
vehicle when the steering wheel is oper-
ated. This is a normal operational noise
and is not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering system is not
functioning properly and may need servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the power steering warning light illu-
minates with the engine running, the
power assist for the steering will cease op-
eration but you will still have control of the
vehicle. At this time, greater steering efforts
are required to operate the steering wheel,
especially in sharp turns and at low speeds.
POWER STEERING
5-172Starting and driving

The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance will
be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
WARNING
• While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshif ting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an
accident.
• If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be lon-
ger and the vehicle may pull to one side
during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking
performance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if
you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
