2019 INFINITI QX60 brakes

If the sonar system detects an object be-
hind the vehicle and the BCI system de-
tects an approaching vehicle at the same
time the following indicators are pro-
vided:– The sonar system chime sounds
– The side BSW/RCTA indicator light
on the side of the approaching vehicle
flashes and
– A yellow rectangular frame appears
in the display If an approaching vehicle or object behind the
vehicle is detected when your vehicle is back-
ing up, a red frame will appear in the display
Aand the system will chime three times.
Then, the brakes will be applied momentarily.
After the automatic brake application, the
driver must depress the brake pedal to main-
tain brake pressure.
If the driver’s foot is on the accelerator pedal,
the system moves the accelerator pedal up-
ward before the braking is applied. However,
if you continue to accelerate, the system will
not engage the brakes.
The system does not operate if the object is
very close to the bumper.

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 its sud-
den braking or if a vehicle cuts in. Always stay
alert when using the ICC system.
ICC (Vehicle-to-vehicle distance
control) mode
In the vehicle-to-vehicle distance control
mode, the ICC system automatically main-
tains a selected distance from the vehicle
traveling in front of you according to that
vehicle’s speed (up to the set speed), or at the
set speed when the road ahead is clear.
The system is intended to enhance the opera-
tion of the vehicle when following a vehicle
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 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 approximately 650 ft (200 m) ahead.Preview Function
The ICC system with the Preview Function
identifies the need to apply emergency brak-
ing by sensing a vehicle ahead in the same
lane, and the distance and relative speed
from it. The system applies the brake pre-
pressure before the driver depresses the
brake pedal and helps improve brake re-
sponse by reducing pedal free play.
∙ This system will not operate when the vehicle is moving at approximately
20 mph (32 km/h) or less.
∙ The pre-pressure function ceases when the following conditions are met:
– When the driver depresses the accel- erator pedal or the brake pedal.
– If the driver does not operate the ac- celerator or brake pedal within ap-
proximately 1 second. ∙ The sensor will not detect:
– Pedestrians or objects in the roadway
– Oncoming vehicles in the same lane
– Motorcycles traveling offset in thetravel lane as illustrated
WARNING
∙ This system is only an aid to assist brak-ing operation and is not a collision warn-
ing or avoidance device. It is the driver’s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.

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.

∙ 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 adheres 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 following are some conditions in which
the sensor cannot properly detect a vehicle
ahead and the system may not operate prop-
erly: ∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ When excessively heavy baggage is loaded in the rear seat or the cargo area
of your vehicle.
The ICC system is designed to automatically
check the sensor’s operation within the limi-
tations of the system. The detection zone of the ICC sensor is lim-
ited. A vehicle ahead must be in the detection
zone for the vehicle-to-vehicle distance de-
tection 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
the vehicle traveling ahead.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious injury or death.
∙ DCA helps maintain a distance to the ve-hicle in front under certain conditions. It
is not a collision avoidance system. Fail-
ure to apply the brakes could result in an
accident.
∙ Always drive carefully and attentively when using the DCA system. Read and
understand the Owner’s Manual thor-
oughly before using the DCA system. Do
not use the DCA system except in appro-
priate road and traffic conditions.
∙ 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 with a warning
chime. To prevent the vehicle from mov-
ing, the driver must depress the brake
pedal.
∙ The DCA system will not apply brake control while the driver’s foot is on the
accelerator pedal. 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 to
maintain a following distance.
DCA SYSTEM OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually decelerate
to maintain the proper following distance.
The DCA system may not be able to deceler-
ate the vehicle under some circumstances.
The DCA system uses a sensor
Alocated
behind the front bumper of the vehicle to
detect vehicles traveling ahead. The sensor
generally detects the signals returned from
the vehicle ahead. Therefore, if the sensor
cannot detect the reflection from the vehicle
ahead, the DCA system may not operate.

DISTANCE CONTROL ASSIST (DCA)
(if so equipped)
5-98Starting and driving

The system is intended to assist the driver to
keep a following distance from the vehicle
ahead traveling in the same lane and direc-
tion.
The distance sensor is located behind the
front bumper
A. If the distance sensorA
detects a slower moving vehicle ahead, the
system will reduce the vehicle speed to help
assist the driver to maintain a following dis-
tance.
The system automatically controls the
throttle and applies the brakes (up to 40% of
vehicle braking power) if necessary.
The detection range of the sensor is approxi-
mately 490 ft (150 m) ahead.
The distance sensor will not detect the fol-
lowing objects:∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane The display is located between the speedom-
eter and tachometer.

WARNING
The DCA system automatically decelerates
your vehicle to help assist the driver to
maintain a following distance from the ve-
hicle ahead. Manually brake when decel-
eration is required to maintain a safe dis-
tance upon sudden braking by the vehicle
ahead or when a vehicle suddenly appears
in front of you. Always stay alert when us-
ing the DCA system.
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.
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.
WARNING
∙ When the vehicle ahead detection indica- tor light is not illuminated, the system
will not control or warn the driver.
∙ Depending on the position of the accel- erator pedal, the system may not be able
to assist the driver to release the accel-
erator pedal appropriately. ∙ If the vehicle ahead comes to a standstill,
the vehicle decelerates to a standstill
within the limitations of the system. The
system will release brake control with a
warning chime once it judges the vehicle
is at a standstill. To prevent the vehicle
from moving, the driver must depress the
brake pedal. (The system will resume
control automatically once the system
reaches 3 mph [5 km/h]).
Overriding the system:
The following driver’s operations override the
system operation. ∙ When the driver depresses the accelera- tor pedal even further while the system is
moving the accelerator pedal upward,
the DCA system control of the accelera-
tor pedal is canceled.
∙ When the driver’s foot is on the accelera- tor pedal, the brake control by the system
is not operated.
∙ When the driver’s foot is on the brake pedal, neither the brake control nor the
alert by the system operates.
∙ When the ICC system is set, the DCA system will be canceled.

DCA SYSTEM LIMITATIONS
WARNING
∙ This system is only an aid to assist the driver and is not a collision warning or
avoidance device. It is the driver’s re-
sponsibility to stay alert, drive safely and
be in control of the vehicle at all times.
∙ This system will not adapt automatically to road conditions.
∙ 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.
∙ The system may not detect the vehicle in front of you in certain road or weather
conditions. To avoid accidents, never use
the DCA system under the following
conditions:
– On roads with 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 sensor area of the front bumper
– On steep downhill roads (frequent braking may result in overheating the
brakes)
– On repeated uphill and downhill roads
∙ Do not use the DCA system if you are towing a trailer. The system may not de-
tect 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. You may need to con-
trol the distance from other vehicles us-
ing the accelerator pedal. Always stay
alert and avoid using the DCA system
where not recommended in this warning
section.
