2017 INFINITI QX60 brake

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
vehicle in front under certain condi-
tions. It is not a collision avoidance sys-
tem. Failure 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
appropriate 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 moving, 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 accelera-
tor pedal upward according to the distance from
and the relative speed of the vehicle ahead to
help assist the driver to maintain a following dis-
tance.
DCA SYSTEM OPERATION
Always pay attention to the operation of the ve-
hicle and be ready to manually decelerate to
maintain the proper following distance. The DCA
system may not be able to decelerate the vehicle
under some circumstances.
The DCA system uses a sensor
Alocated be-
hind 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 sys-
tem may not operate.

DISTANCE CONTROL ASSIST (DCA)
(if so equipped)
5-96Starting 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 direction.
The distance sensor is located behind the front
bumper
A. If the distance sensorAdetects a
slower moving vehicle ahead, the system will
reduce the vehicle speed to help assist the driver
to maintain a following distance.
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 following
objects.
● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane The display is located between the speedometer
and tachometer.
1. DCA system switch indicator: Indicates that the dynamic driver assistance
switch is on. 2. Vehicle ahead detection indicator:
Indicates whether it detects a vehicle in front
of you.
WARNING
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.
DCA Indicators
LSD2068LIC2889
Starting and driving5-97

The DCA system helps assist the driver to keep a
following distance to the vehicle ahead by brak-
ing 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 accelerator
pedal, the system activates the brakes to
decelerate smoothly as necessary. If the ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill within the limita-
tions of the system.
● If the driver’s foot is on the accelerator pedal,
the system moves the accelerator pedal up-
ward to assist the driver to release the ac-
celerator pedal.
When brake operation by driver is required:
The system alerts the driver by a warning chime
and blinking the vehicle ahead detection indica-
tor. If the driver’s foot is on the accelerator pedal
after the warning, the system moves the accel-
erator pedal upward to assist the driver to switch
to the brake pedal. The stoplights 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 indi-
cator 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
accelerator pedal appropriately.
● If the vehicle ahead comes to a stand-
still, the vehicle decelerates to a stand-
still 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 accelerator
pedal even further while the system is mov-
ing the accelerator pedal upward, the DCA
system control of the accelerator pedal is
canceled.
● When the driver’s foot is on the accelerator
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 sys-
tem 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
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, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween 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
detect a vehicle ahead.
● In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You may
need to control the distance from other
vehicles using the accelerator pedal. Al-
ways stay alert and avoid using the DCA
system where not recommended in this
warning section.
5-100Starting and driving

The following are some conditions in which the
sensor cannot detect the signals:● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
detection
● When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the front
bumper area around the distance sensor is cov-
ered with dirt or is obstructed, the system will
automatically cancel. If the front bumper area of
the distance sensor is covered with ice, a trans-
parent or translucent vinyl bag, etc., the DCA
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 distance from the vehicle
ahead. Be sure to check and clean the front
bumper area around the distance sensor regu-
larly. The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as nec-
essary and if the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill. However,
the DCA system can only apply up to 40% of the
vehicle’s total braking power. If a vehicle moves
into the traveling lane ahead or if a vehicle travel-
ing ahead rapidly decelerates, the distance be-
tween vehicles may become closer because the
DCA system cannot decelerate 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 additional information, refer to “Approach
warning” in this section.
This system only brakes and moves the accelera-
tor pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.
The DCA system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead.
Starting and driving5-101

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the sensor may detect ve-
hicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may cause
the system to work inappropriately.
The detection of vehicles may also be affected by
vehicle operation (steering maneuver or traveling
position in the lane, etc.) or vehicle condition.If
this occurs, the 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.Approach warning
If your vehicle comes closer to the vehicle ahead
due to rapid deceleration of that vehicle or if
another vehicle cuts in, the system warns the
driver with the chime and DCA system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection indicator blinks. 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 in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.

1. Vehicle ahead detection indicator
2. FEB with pedestrian detection emergencywarning indicator
3. FEB with pedestrian detection system warn- ing light
SYSTEM OPERATION
The FEB with pedestrian detection system oper-
ates at speeds above approximately 3 mph
(5 km/h). For the pedestrian detection function,
the FEB with pedestrian detection system oper-
ates at speeds between 6 – 37 mph (10 –
60 km/h).
If a risk of a forward collision with a vehicle is
detected, the FEB with pedestrian detection sys-
tem will first provide a warning to the driver by
flashing the vehicle ahead detection indicator
and providing an audible alert. In addition, the
FEB with pedestrian detection system pushes
the accelerator pedal up, and then the system
applies partial braking. If the driver applies the
brakes quickly and forcefully, but the FEB with
pedestrian detection system detects that there is
still the possibility of a forward collision, the sys-
tem will automatically increase the braking force.
If the risk of a collision becomes imminent and the
driver does not take action, the FEB with pedes-
trian detection system issues the second warning
to the driver by flashing the FEB with pedestrian

detection emergency warning indicator (red) ,
providing an audible warning, and then automati-
cally applies harder braking.
If a risk of a forward impact with a pedestrian is
detected, the FEB with pedestrian detection sys-
tem will provide a warning to the driver by flashing
the FEB with pedestrian detection emergency
warning indicator (red) , provides an audible alert
and the system will apply partial baking. If the
driver applies the brakes quickly and forcefully
but the FEB with pedestrian detection system
detects that there is still the possibility of a for-
ward impact with a pedestrian, the system will
automatically increase the braking force. If the
risk of collision becomes imminent and the driver
does not take action, the FEB with pedestrian
detection system automatically applies harder
braking.
NOTE:
The vehicle’s brake lights come on when
any braking is performed by the FEB with
pedestrian detection system.
Depending on vehicle speed and distance to the
vehicle or pedestrian ahead, as well as driving
and roadway conditions, the system may help the
driver avoid a forward collision or may help miti-
gate the consequences if a collision should be
unavoidable. If the driver is handling the steeringwheel, accelerating or braking, the FEB with pe-
destrian detection system will function later or
will not function.
The automatic braking will cease under the fol-
lowing conditions:
● When the steering wheel is turned to avoid a
collision.
● When the accelerator pedal is depressed.
● When there is no longer a vehicle or a pe-
destrian detected ahead.
If the FEB with pedestrian detection system has
stopped the vehicle, the vehicle will remain at a
standstill for approximately 2 seconds before the
brakes are released.
