2021 INFINITI QX50 brake

Normally when controlling the distance to a
vehicle ahead, the system automatically ac-
celerates or decelerates your vehicle accord-
ing to the speed of the vehicle ahead.
Depress the accelerator to properly acceler-
ate your vehicle when acceleration is required
for a lane change. Depress the brake pedal
when deceleration is required to maintain a
safe distance to the vehicle ahead due to
sudden braking or if a vehicle cuts in. Always
stay alert when using the ICC system.
No vehicle detected ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, similar to
standard cruise control, as long as no vehicle
is detected in the lane ahead. The ICC system
displays the set speed.
Vehicle detected ahead
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by
controlling the throttle and applying the
brakes to match the speed of a slower vehicle
ahead. The ICC system then controls the ve-
hicle speed based on the speed of the vehicle
ahead to maintain the driver selected
distance.
NOTE:
• The stop lights of the vehicle come onwhen braking is performed by the ICC
system.

• When the brake is applied by the system, anoise may be heard. This is not a
malfunction.
When the ICC system detects a vehicle
ahead, the vehicle ahead detection indicator
and the speed control status indicator (dis-
tance control mode) illuminates (solid green
).
Vehicle ahead stops
When the vehicle ahead decelerates to stop,
your vehicle decelerates to a standstill within
the system capability. Once your vehicle
stops, the ICC system automatically applies
the brakes to keep the vehicle stopped. When
your vehicle is at a standstill, the “(RES+)
Press to start” message is displayed on the
vehicle information display.
NOTE:
When your vehicle stops for less than 3 sec-
onds, your vehicle will automatically follow
the vehicle as it accelerates from a stop.
Vehicle ahead accelerates
When your vehicle is stopped and the vehicle
ahead begins to accelerate, push the RES+
switch or lightly depress the accelerator
pedal. The ICC system starts to follow the
vehicle ahead.
Vehicle ahead not detected
When a vehicle is no longer detected ahead,
the ICC system gradually accelerates your
vehicle to resume the previously set vehicle
speed. The ICC system then maintains the set
speed.
When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off
and speed control status indicator (maintain
speed control mode) illuminates (green out-
line
).
The ICC system gradually accelerates to the
set speed, but you can depress the accelera-
tor pedal to quickly accelerate. When a ve-
hicle is no longer detected and your vehicle is
traveling under approximately 15 mph (25
km/h), the ICC system automatically cancels. When passing another vehicle, the set speed
indicator
OBflashes when the vehicle speed
exceeds the set speed. The vehicle ahead
detection indicator turns off when the area
ahead of the vehicle is open. When the pedal
is released, the vehicle returns to the previ-
ously set speed. Even though your vehicle
speed is set in the ICC system, you can de-
press the accelerator pedal when it is neces-
sary to accelerate your vehicle rapidly.

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.

WARNING
In order to reduce the risk of a collision that
may result in serious injury or death, please
be aware of the following:
• This function is only activated with the
left turn signal and will briefly accelerate
the vehicle even if a lane change is not
initiated. This can include non-passing
situations such as left side exits.
• Ensure that when passing another ve-
hicle, the adjacent lane is clear before ini-
tiating the pass. Sudden changes in traf-
fic may occur while passing- always
manually steer or brake as needed- never
solely rely on the system.
ICC system limitations
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious 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 automati-
cally 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 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
vehicles.
• When the ICC system automatically
brings the car to a stop, your vehicle can
automatically accelerate if the vehicle is
stopped for less than approximately 3
seconds. Be prepared to stop your ve-
hicle if necessary. •
Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance.
The ICC system may not be able to main-
tain the selected distance between ve-
hicles (following distance) or selected
vehicle speed under some circumstances.
• The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the ICC system under the following con-
ditions:
– On roads with heavy, high-speed
traffic or sharp curves
– On slippery road surfaces such as on
ice or snow, etc.
– During bad weather (rain, fog, snow,
etc.)
– When rain, snow or dirt adhere to the
bumper around the distance sensor
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
5-92Starting and driving

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.

Action to take:
When the conditions listed above are no lon-
ger present, turn the system off using the
ProPILOT Assist switch. Turn the ProPILOT
Assist system back on to use the system.
NOTE:
When the ICC system is canceled under
the following conditions at a standstill,
the electronic parking brake is automati-
cally activated:
• Any door is open.
• The driver’s seat belt is not fastened.
• Your vehicle has been stopped by the ICCsystem for approximately 3 minutes or
longer.
• The shift lever is not in the D (Drive) posi- tion or manual shift mode.
• The VDC system is turned off.
• When distance measurement becomes im- paired due to adhesion of dirt or obstruc-
tion to the sensor.
• When the radar signal is temporarily interrupted.
Condition B
When the radar sensor of the front bumper is
covered with dirt or is obstructed, the ICC
system will automatically be canceled. The chime will sound and the “Unavailable:
Front Radar Blocked” warning message will
appear in the vehicle information display.
Action to take:
If the warning message appears, stop the
vehicle in a safe place, press the Park button
to place the vehicle in the P (Park) position,
and turn the engine off. When the radar sig-
nal is temporarily interrupted, clean the sen-
sor area of the front bumper and restart the
engine. If the “Unavailable: Front Radar
Blocked” warning message continues to be
displayed, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
Condition C
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next to
long walls), the system may illuminate the
system warning light and display the “Un-
available: Front Radar Blocked” message.
Action to take:
When the above driving conditions no longer
exist, turn the system back on.
ICC system malfunction
If the ICC system malfunctions, it will be
turned off automatically, a chime will sound,
and the speed control status warning (or-
ange) will illuminate.
Action to take:
If the warning light comes on, stop the vehicle
in a safe place. Turn the engine off, restart
the engine and set the ICC system again. If it
is not possible to set the ICC system or the
indicator stays on, it may be a malfunction.
Although the normal driving can be contin-
ued, the ICC system should be inspected. It is
recommended that you visit an INFINITI re-
tailer for this service.
ICC sensor maintenance
The radar sensor is located on the front of the
vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
• Always keep the sensor area clean.
• Do not strike or damage the areas around
the sensor.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the sensor. This could cause failure or
malfunction.

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.
– When driving on roads with discon-
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.
– 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 an-
other object adheres to the camera
unit
– When the lens of the camera unit is
foggy
– When strong light (for example, sun-
light or high beams from oncoming
vehicles) shines on the camera
