sensor INFINITI QX60 2016 Repair Manual

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 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.
Starting and driving5-99

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.
5-100Starting and driving

DCA DRIVING SITUATIONS
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 the
vehicle traveling ahead.
DCA Detection Zone

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.

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) .
SYSTEM TEMPORARILY
UNAVAILABLE
Under the following conditions, the DCA system
will not operate and the DCA cancellation mes-
sage will pop up:
● When the SNOW mode switch is ON (To
use the DCA system, turn off the SNOW
mode switch, then turn on the dynamic driver
assistance switch.)

Condition B:
When the sensor area of the front bumper is dirty,
making it impossible to detect a vehicle ahead,
the DCA system is automatically canceled.
The chime sounds and the system warning light
(orange) will come on and the “Sensor Blocked”
indicator will appear.
Action to take:
If the warning light comes on, park the vehicle in a
safe place, turn the engine off. Clean the sensor
area of the bumper and then perform the settings
again.Condition C:
When the DCA system is not operating properly,
the chime sounds and the system warning light
(“DCA” orange) 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,
and turn on the DCA system again.If it is not possible to set the system or the
indicator stays on, it may indicate that the
system is malfunctioning. Although the ve-
hicle is still driveable under normal condi-
tions, have the vehicle checked. It is recom-
mended that you visit an INFINITI retailer
for this service.
SYSTEM MAINTENANCE
The sensor for the DCA system is common with
ICC and is located behind the front bumper.
