INFINITI QX60 2015 Owner's Manual

Warning light
When the system is not operating properly, the
chime sounds and the system warning light (or-
ange) will come on.
Action to take:
If the warning light comes on, park the vehicle in a
safe place. Turn the engine off, restart the engine,
resume driving and then perform the setting
again.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
driveable under normal conditions, have
the vehicle checked at an INFINITI retailer.
PREVIEW FUNCTION (for ICC
system equipped models)
The ICC system with the Preview Function iden-
tifies the need to apply emergency braking by
sensing the vehicle ahead in the same lane and
the distance to the vehicle ahead and relative
speed from it. It applies the brake pre-pressure
before the driver depresses the brake pedal and
helps improve brake response by reducing pedal
free play.
For additional information, refer to “Brake assist”
in this section.
The (DCA) system brakes and moves the accel-
erator pedal upward according to the distance
from and the relative speed of the vehicle ahead
to help assist the driver to maintain a following
distance.
WARNING
●
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.

PRECAUTIONS ON DCA SYSTEM
The system is intended to assist the driver to
maintain an appropriate 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 an appropriate 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.
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.
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
● Motorcycles traveling offset in the travel lane
WARNING
●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
LSD2098
Starting and driving5-73

– On steep downhill roads (frequentbraking 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.
DCA 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. 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,
LSD2098
5-74Starting and driving

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.The detection zone of the sensor is limited. A
vehicle ahead must be in the detection zone for
the system to operate.
A vehicle ahead may move outside of the detec-
tion 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 enter-
ing the lane ahead may not be detected until the
vehicle has completely moved into the lane.
If
this occurs, the system may warn you by
blinking the system indicator and sounding
the chime. The driver may have to manually control the proper distance away from ve-
hicle traveling ahead.
DCA Detection Zone

Starting and driving5-75

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.DCA system display and indicators
The display is located between the speedometer
and tachometer.

System operation
WARNING
The Distance Control Assist system auto-
matically decelerates your vehicle to help
assist the driver to maintain a following
distance from the vehicle ahead. Manually
brake when deceleration is required to
maintain a safe distance upon sudden brak-
ing by the vehicle ahead or when a vehicle
suddenly appears in front of you. Always
stay alert when using the DCA system.
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.
LSD2126
5-78Starting and driving

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 cancelled.
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.

NOTE:
The approach warning chime may sound
and the system display may blink when ICC
sensor detects vehicles in other lanes
Aor
objects on the side of the road
A. This may
cause the DCA system to operate inappro-
priately. The ICC sensor may detect these
objects when the vehicle is driven on wind-
ing roads, narrow roads, hilly roads or when
entering or exiting a curve. In these cases
you will have to manually control 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 vehicle condition
(for example, if a vehicle is being driven with some
damage) .
Automatic cancellation
Condition A:
Under the following conditions, the DCA system
is automatically canceled. The chime will sound
and the DCA cancellation message will display.
●When the VDC system is turned off
● When the VDC or ABS (including the TCS)
operates
● When the SNOW mode switch is turned
ON
