2020 INFINITI QX50 brakes

∙ The system may not detect the vehicle infront 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. ∙ In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert and
avoid using the ICC system where not
recommended in this warning section.
The radar sensor will not detect the following
objects: ∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane
The sensor generally detects the signals re-
turned from the vehicle ahead. Therefore, if
the sensor cannot detect the reflection from
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which the
sensor cannot properly detect a vehicle ahead
and the system may not operate properly:
∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ When your vehicle is towing a trailer, etc.
∙ When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle. The ICC system is designed to automatically
check the sensor’s operation within the limi-
tations of the system.
When the sensor is covered with dirt or is
obstructed, the system will automatically be
canceled. If the sensor is covered with ice, a
transparent or translucent vinyl bag, etc., the
ICC system may not detect them. In these
instances, the vehicle-to-vehicle distance
control mode may not cancel and may not be
able to maintain the selected following dis-
tance from the vehicle ahead. Be sure to
check and clean the sensor regularly.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the detec-
tion zone for the vehicle-to-vehicle distance
detection mode to maintain the selected dis-
tance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are
traveling offset from the centerline of the
lane. A vehicle that is entering the lane ahead
may not be detected until the vehicle has
completely moved into the lane.
If this occurs, the ICC system may warn you
by blinking the system indicator and sound-
ing the chime. The driver may have to manu-
ally control the proper distance away from
vehicle traveling ahead.

If it is not possible to set or the indicator
stays on, it may indicate that the system is
malfunctioning. Although the vehicle is still
drivable under normal conditions, have the
vehicle checked. It is recommended that you
visit an INFINITI retailer for this service.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.
∙ Never unfasten your safety belt when us- ing ProPILOT Assist. Doing so automati-
cally cancels the ProPILOT Assist
system.
∙ The ProPILOT Assist system does not re- act to stationary and slow moving
vehicles.

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
outline
).
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 can-
cels.

∙ Always pay attention to the operation ofthe 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 with heavy, high-speed traf- fic 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 – 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.
∙ In some road or traffic conditions, a ve- hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert and
avoid using the ICC system where not
recommended in this warning section.
The ICC system will not detect the following
objects: ∙ Stationary or slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane The following are some conditions in which
the radar sensor cannot properly detect a
vehicle ahead and the system may not oper-
ate properly:
∙ When the sensor detection is reduced (conditions such as rain, snow, fog, dust
storms, sandstorms, and road spray from
other vehicles)
∙ Driving on a steep downhill slope or roads with sharp curves
∙ Driving on a bumpy road surface, such as an uneven dirt road
∙ If dirt, ice, snow or other material is cov- ering the radar sensor area
∙ A complicated-shaped vehicle such as a car carrier trailer or flatbed truck/trailer is
near the vehicle ahead.
∙ Interference by other radar sources
∙ When your vehicle is towing a trailer, etc.
∙ When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle.
The ICC system is designed to automatically
check the radar sensor’s operation within the
limitations of the system.

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.

∙ As there is a performance limit to the dis-tance control function, never rely solely
on the DCA 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.
∙ Always pay attention to the operation of the vehicle and be ready to manually de-
celerate to maintain the proper following
distance. The DCA system may not be
able to decelerate the vehicle under some
circumstances.
∙ This system only brakes and moves the accelerator pedal upward to help assist
the driver to maintain a following dis-
tance from the vehicle ahead. Accelera-
tion should be operated by the driver.
∙ The DCA system does not control the ve- hicle speed or warn you when you ap-
proach stationary and slow moving ve-
hicles. You must pay attention to vehicle
operation to maintain proper distance
from vehicles ahead. ∙ The DCA system automatically deceler-
ates your vehicle to help assist the driver
to maintain a following distance from the
vehicle ahead. Manually brake when de-
celeration is required to maintain a safe
distance upon sudden braking by the ve-
hicle ahead or when a vehicle suddenly
appears in front of you. Always stay alert
when using the DCA system.
∙ If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill within
the limitations of the system. The system
will cancel with a warning chime once it
judges that the vehicle has come to a
standstill. To prevent the vehicle from
moving, the driver must depress the
brake pedal.
The DCA system is intended to assist the
driver in keeping a following distance from
the vehicle ahead traveling in the same lane
and direction.
If the radar sensor detects a slower moving
vehicle ahead, the system will reduce the ve-
hicle speed to help assist the driver to main-
tain a following 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 (200m) ahead.
5-134Starting and driving

The DCA system brakes and moves the ac-
celerator pedal upward according to the dis-
tance from and the relative speed of the ve-
hicle ahead to help assist the driver in
maintaining a following distance. The system
will decelerate as necessary and if the vehicle
ahead comes to a stop, the vehicle deceler-
ates to a standstill. However, the DCA sys-
tem can only apply up to approximately 40%
of the vehicle’s total braking power. If a ve-
hicle moves into the traveling lane ahead or if
a vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the DCA system cannot de-
celerate the vehicle quickly enough. If this
occurs, the DCA system will sound a warning
chime and blink the system display to notify
the driver to take necessary action. For addi-
tional information, refer to “Approach warn-
ing” in this section.The DCA system helps assist the driver to
keep a following distance to the vehicle
ahead by braking and moving the accelerator
pedal upward in the normal driving condition.
When a vehicle is detected ahead:
The vehicle ahead detection indicator comes
on.When vehicle approaches a vehicle ahead:
∙ If the driver’s foot is not on the accelera- tor pedal, the system activates the brakes
to decelerate smoothly as necessary. If
the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system.
∙ If the driver’s foot is on the accelerator pedal, the system moves the accelerator
pedal upward to assist the driver to re-
lease the accelerator pedal.
When brake operation by driver is required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead detec-
tion indicator. If the driver’s foot is on the
accelerator pedal after the warning, the sys-
tem moves the accelerator pedal upward to
assist the driver to switch to the brake pedal.
NOTE: ∙ The stop lights of the vehicle come on
when braking is performed by the DCA
system.
∙ When the brake operates, a noise may be
heard. This is not a malfunction.
