steering wheel INFINITI QX50 2021 Workshop Manual

Cut-in detection
If a vehicle moves into your traveling lane
near your vehicle, the ICC system may inform
the driver by flashing the vehicle ahead de-
tection indicator.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and ICC sys-
tem display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
• The chime sounds.
• The vehicle ahead detection indicator andset distance indicator blink.
• You judge it necessary to maintain a safe distance.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are:
• When the vehicles are traveling at the same speed and the distance between vehicles is
not changing. • When the vehicle ahead is traveling faster
and the distance between vehicles is
increasing.
• When a vehicle cuts in near your vehicle.
The warning chime will not sound when:
• Your vehicle approaches other vehicles that are parked or moving slowly.
• The accelerator pedal is depressed, over- riding the system.
NOTE:
The approach warning chime may sound and
the system display may flash when the radar
sensor detects objects on the side of the ve-
hicle or on the side of the road. This may
cause the ICC system to decelerate or accel-
erate the vehicle. The radar sensor may de-
tect these objects when the vehicle is driven
on winding, narrow, or hilly roads or when
the vehicle is entering or exiting a curve. In
these cases, you will have to manually con-
trol 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 conditions (for example, if a vehicle is
being driven with some damage).
Acceleration when passing
When the ICC system is engaged above 44
mph and following a slower vehicle (below
ICC set speed), and the turn signal is acti-
vated to the left, the ICC system will auto-
matically start to accelerate the vehicle to
help initiate passing on the left and will begin
to reduce the distance to vehicle directly
ahead. Only the left side turn signal operates
this feature. As the driver steers the vehicle
and moves into the passing lane, if no vehicle
is detected ahead the ICC system will con-
tinue to accelerate to the ICC system set
speed. If another vehicle is detected ahead,
then the vehicle will accelerate up to the fol-
lowing speed of that vehicle. If the vehicle is
not steered into the left lane to pass, the
acceleration will stop after a short time and
regain the set following distance. Accelera-
tion can be stopped at any point by depress-
ing the brake pedal or the CANCEL switch on
the steering wheel.
Starting and driving5-91

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar sen-
sor may detect vehicles in a different lane, or
may temporarily not detect a vehicle 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 maneu-
ver 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 distance away
from the vehicle traveling ahead.
Automatic cancellation
The following are conditions in which the ICC
system may be temporarily unavailable. In
these instances, the ICC system may not can-
cel and may not be able to maintain the se-
lected following distance from the vehicle
ahead.Condition A
Under the following conditions, the ICC sys-
tem 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 (25 km/h).
• Your vehicle has been stopped by the ICC system for approximately 3 minutes or
longer.
• The shift lever is not in the D (Drive) position or manual shift mode.
• The electronic parking brake is applied.
• The VDC system is turned off.
• The Forward Emergency Braking with Pe- destrian Detection applies harder braking.
• VDC (including the traction control system) operates.
• A wheel slips.
• When distance measurement becomes im- paired due to adhesion of dirt or obstruc-
tion to the sensor.
• When the radar signal is temporarily interrupted.

• Do not attach metallic objects near thesensor 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 an
INFINITI retailer.
The camera sensor is located above the in-
side mirror.
To keep the proper operation of the systems
and prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely 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 an
INFINITI retailer.
STEERING ASSIST
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the Steering Assist
could result in serious injury or death.
• The Steering Assist is not a replacement
for proper driving procedures and is not
designed to correct careless, 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
responsibility 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 Steering Assist
does not function in all driving, traffic,
weather, and road conditions. Always
drive safely, pay attention to the opera-
tion of the vehicle, and manually control
your vehicle 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 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 vehicle 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 driv-
ing. 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 As-
sist. To avoid serious injury or death, do
not rely on the system to prevent acci-
dents or to control 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 sys-
tem to help keep your vehicle near the center
of the lane when driving. The Steering Assist
is combined with the Intelligent Cruise Con-
trol (ICC) system. For additional information,
see “Intelligent Cruise Control (ICC) (for ve-
hicles with ProPILOT Assist)” (P. 5-87).
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearlydetected.
• A vehicle ahead is detected (when the ve- hicle 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 as-
sist function is disabled after the wiper op-
erates for approximately 10 seconds).

Lane Departure Prevention (LDP)
When a curve or strong cross wind exceeds
the capabilities of the Steering Assist and
your vehicle approaches either the left or the
right side of the traveling lane, a warning
chime sounds and the LDP indicator light
(orange) on the instrument panel flashes to
alert the driver. Then, the LDP system auto-
matically 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.
LSD2972
Starting and driving5-99

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 after the warning has been displayed,
an audible alert sounds and the warning
flashes in the vehicle information display, fol-
lowed by a quick brake application to request
the driver to take control of the vehicle again.
If the driver still does not respond, the ProPI-
LOT 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 op-
erating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for a hands-
free driving. Always keep your hands on
the steering wheel and drive your vehicle
safely. Failure to do so could cause a colli-
sion resulting in serious 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 steering wheel and a sequence
of warnings may occur. When the driver
holds and operates the steering wheel again,
the warnings turn off.
Steering Assist limitations
WARNING
• In the following situations, the camera
may not detect lane markers correctly or
may detect lane markers incorrectly 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.

tinued lane markers
– When driving on roads with a widen-
ing 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 remaining after road
repairs (the Steering Assist could de-
tect 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.

DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations of
the DCA system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
• This system will not adapt automatically
to road conditions. Do not use the sys-
tem on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
• The DCA system will not apply brake
control while the driver’s foot is on the
accelerator pedal.
• As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This system
does not correct careless, inattentive or
absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by
depressing the brake pedal, depending
on the distance to the vehicle ahead and
the surrounding circumstances in order
to maintain a safe distance between
