2019 NISSAN ALTIMA steering wheel

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
sounding the chime unexpectedly. You will
have to manually control the proper dis-
tance away from the vehicle traveling
ahead.
Automatic cancellation
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
Under the following conditions, the ICC system
is automatically canceled. A chime will sound
and the system will not be able to be set:
∙ Any door is open.
∙ The driver’s seat belt is not fastened.
∙ The vehicle ahead is not detected and
your vehicle is traveling below the
speed of 15 mph (24 km/h).
∙ Your vehicle has been stopped by the ICC system for approximately 3 minutes
or longer.
∙ The shif t lever is not in the D (Drive) po- sition or manual shif t mode.
∙ The electronic parking brake is applied.
∙ The VDC system is turned off.
∙ The AEB applies harder braking.
∙ VDC (including the traction control sys- tem) operates.
∙ A wheel slips.
∙ When distance measurement be- comes impaired due to adhesion of dirt
or obstruction to the sensor.
∙ When the radar signal is temporarily in- terrupted.

5-112Starting and driving

∙ The Steering Assist only steers the ve-hicle 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 attentively when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering
Assist. To avoid serious injury or
death, do not rely on the system to
prevent accidents or to control the ve-
hicle’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, refer to “Intelligent Cruise Con-
trol (ICC) (for vehicles with ProPILOT Assist)”
in this section.
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]).
∙ The driver grips the steering wheel.
∙ The vehicle is driven at the center of the lane.
∙ The turn signals are not operated.
∙ The windshield wiper is not operated in the high (HI) speed operation (the
Steering Assist function is disabled
af ter the wiper operates for approxi-
mately 10 seconds).

Hands on detection
When the Steering Assist is activated, it
monitors the driver’s steering wheel opera-
tion.
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
1
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, nonstandard 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 objects,
such as shadows, snow, water,
wheel ruts, seams, or lines remain-
ing 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
accident.
– 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
– When the lens of the camera unit is foggy
– When strong light (for example, sunlight or high beams from on-
coming vehicles) shines on the
camera
– When the headlights are not bright due to dirt on the lens or the head-
lights are off in tunnels or darkness
– When a sudden change in bright- ness occurs (for example, when the
vehicle enters or exits a tunnel or is
under a bridge)
5-118Starting and driving

– When driving on roads where thetraveling lane merges or separates
or where there are temporary lane
markers because of road
construction
– When there is a lane closure due to road repairs
– When driving on a bumpy road sur- face, such as an uneven dirt road
– When driving on sharp curves or winding roads
– When driving on repeated uphill and downhill roads
∙ Do not use the Steering Assist under the following conditions because the
system will not operate properly:
– When driving with a tire that is not within normal tire conditions (for
example, tire wear, abnormal tire
pressure, installation of a spare
tire, tire chains, nonstandard
wheels)
– When the vehicle is equipped with non-original brake or suspension
parts – When an object such as a sticker or
cargo obstructs the camera
– When excessively heavy baggage is loaded in the rear seat or lug-
gage area of your vehicle
– When the vehicle load capacity is exceeded
– When towing a trailer or other vehicle
∙ Excessive noise will interfere with the warning chime sound, and the beep
may not be heard.
∙ For the ProPILOT Assist system to op- erate properly, the windshield in front
of the camera must be clean. Replace
worn wiper blades. The correct size
wiper blades must be used to help
make sure the windshield is kept
clean. Only use Genuine NISSAN wiper
blades, or equivalent wiper blades,
that are specifically designed for use
on your vehicle model and model
year. It is recommended that you visit
a NISSAN dealer for the correct parts
for your vehicle.Steering Assist temporary
standby
Automatic standby due to driving opera-
tion:
When the driver activates the turn signal,
the Steering Assist is temporarily placed in
a standby mode. (The Steering Assist re-
starts automatically when the operating
conditions are met again.)
Automatic standby:
In the following cases, a warning message
is displayed along with the chime, and the
Steering Assist is placed in a temporary
standby mode. (The Steering Assist re-
starts automatically when the operating
conditions are met again.)
∙ When lane markers on both sides are no longer detected
∙ When a vehicle ahead is no longer de- tected under approximately 37 mph
(60 km/h)

RAB SYSTEM OPERATION
When the shif t lever is in the R (Reverse)
position and the vehicle speed is less than
approximately 9 mph (15 km/h), the RAB
system operates.
If a risk of a collision with an obstacle is de-
tected when your vehicle is backing up, the
RAB system warning indicator will flash in
the vehicle information display, a red frame
will appear in the center display (for vehicles
with the Intelligent Around View Monitor sys-
tem), and the system will chime three times.
The system will then automatically apply the
brakes. Af ter the automatic brake applica-
tion, the driver must depress the brake pedal
to maintain brake pressure.
NOTE:
∙ The brake lights of the vehicle come
on when braking is performed by the
RAB system.
∙ When the brakes operate, a noise may
be heard. This is not a malfunction.

5-126Starting and driving

∙ Once the automatic brake controloperates, it does not operate again if
the vehicle approaches the same
obstacle.
∙ The automatic brake control can only operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
∙ In the following situations, the RAB system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep hill.
– The vehicle’s posture is changed (e.g., when driving over a bump).
– The vehicle is driven on a slippery road.
– The vehicle is turned sharply by turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN recommended are used. – The brakes are cold at low ambient
temperatures or immediately af ter
driving has started.
– The braking force becomes poor due to wet brakes af ter driving
through a puddle or washing the
vehicle.
∙ Turn the RAB system off in the follow- ing conditions to prevent the occur-
rence of an unexpected accident
resulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed truck.
– The vehicle is on the chassis dynamometer.
– The vehicle drives on an uneven road surface.
– Suspension parts other than those designated as Genuine NISSAN
parts are used. (If the vehicle
height or the vehicle body inclina-
tion is changed, the system may
not detect an obstacle correctly.) ∙ Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “Sys-
tem fault” warning message will appear in
the vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.

NOTE:
The vehicle’s brake lights come on when
braking is performed by the AEB system.
Depending on vehicle speed and distance
to the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may
help mitigate the consequences of a colli-
sion, should one be unavoidable. If the
driver is handling the steering wheel, accel-
erating or braking, the AEB system will
function later or will not function.
The automatic braking will cease under the
following conditions:∙ When the steering wheel is turned as far as necessary to avoid a collision.
∙ When the accelerator pedal is de- pressed.
∙ When there is no longer a vehicle de- tected ahead. If the AEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the
brakes are released.
