2019 INFINITI QX50 Brakes

If the radar sensorBdetects a slower mov-
ing vehicle ahead, the system will reduce the
vehicle speed so that your vehicle follows the
vehicle in front at the selected distance.
The system automatically controls the
throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.

1System set display with vehicle ahead
2System set display without vehicle 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 system then controls the vehicle
speed based on the speed of the vehicle
ahead to maintain the driver selected dis-
tance.
NOTE:
∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system.
∙ When the brake operates, a noise may be
heard. This is not a malfunction.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and
selected distance.
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.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.

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 foruse 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 dis-
tance control function, never rely solely
on the ICC system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain a safe distance between vehicles.
∙ If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill within
the limitations of the system. The system
will cancel once it judges that the vehicle
has come to a standstill and sound a
warning chime. To prevent the vehicle
from moving, the driver must depress the
brake pedal.
∙ Always pay attention to the operation of the vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(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
conditions:
– On roads where the traffic is heavy or there are 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
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the ProPILOT Assist
system could result in serious injury or
death.
∙ ProPILOT Assist is not a self-driving sys-tem. Within the limits of its capabilities,
as described in this manual, it helps the
driver with certain driving activities.
∙ The ProPILOT Assist system is not a re- placement for proper driving procedures
and is not designed to correct careless,
inattentive or absent-minded driving.
ProPILOT Assist will not always steer
the vehicle to keep it in the lane. The Pro-
PILOT Assist system 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.
∙ There are limitations to the ProPILOT Assist system capability. The ProPILOT
Assist system does not function in all
driving, traffic, weather, and road condi-
tions. 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 ProPILOT Assist system is only an
aid to assist the driver and is not a colli-
sion warning or avoidance device.
∙ The ProPILOT Assist system is for high- way use only and is not intended for city
driving. Failure to apply the brakes or
steer the vehicle when necessary may re-
sult in a serious accident.
∙ Always observe posted speed limits and do not set the speed over them.
∙ Never take your hands off the steering wheel when driving. Always keep your
hands on the steering wheel and drive
your vehicle safely.
∙ The ProPILOT Assist system does not re- act to stationary and slow moving
vehicles.
∙ Always drive carefully and attentively when using the ProPILOT Assist system.
Read and understand the Owner’s
Manual thoroughly before using the Pro-
PILOT Assist system. To avoid serious in-
jury or death, do not rely on the system to
prevent accidents or to control the vehi-
cle’s speed in emergency situations. Do
not use the ProPILOT Assist system ex-
cept in appropriate road and traffic
conditions. The ProPILOT Assist system is intended to
enhance the operation of the vehicle when
following a vehicle traveling in the same lane
and direction.
The ProPILOT Assist system uses a multi-
sensing front camera
Ainstalled behind the
windshield and a radar sensor located on the
front of the vehicle
Bto measure the dis-
tance to the vehicle ahead in the same lane
and to monitor the lane markers. If the vehicle
detects a slower moving vehicle ahead, the
system will reduce the vehicle speed so that
your vehicle follows the vehicle in front at the
selected distance. The system will also help
keep the vehicle centered in the traveling lane
when clear lane markings are detected.

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 dis-
tance.
NOTE:∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system. ∙
When the brake is applied by the system,
a noise may be heard. This is not a mal-
function.
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
