2014 INFINITI QX60 HYBRID sensor

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.Distance control assist system display

The display is located between the speedometer
and tachometer.

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 Distance
Control Assist system is automatically canceled.
The chime will sound and the Distance Control
Assist (DCA) cancellation message will pop up.

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 at an
INFINITI retailer.
Sensor maintenance
How to handle the sensor:
The sensor for the DCA system is common with
Intelligent Cruise Control and is located behind
the front bumper.
To handle the sensor, see “Intelligent Cruise
Control (ICC) system (Full speed range)” in this
section.The Forward Collision Warning (FCW) system
will warn the driver by a warning light and chime
when your vehicle is getting close to the vehicle
ahead in the traveling lane.
The FCW system will function when your vehicle
is driven at speeds of approximately 10 MPH
(15 km/h) and above.
The FCW system uses the distance sensor
A
located behind the front bumper to measure the
distance to the vehicle ahead. When the system
judges that your vehicle is getting close to the
vehicle ahead in the travel lane, the vehicle ahead
detection indicator light on the instrument panel
blinks and a warning chime sounds.
The FCW system can be turned on/off by push-
ing the warning systems switch. The warning
systems ON indicator light
1on the switch will
illuminate when the system is ON.

PRECAUTIONS ON FCW SYSTEM
WARNING
●The FCW system is intended to warn
you before a collision occurs; it cannot
prevent a collision. It is the driver’s re-
sponsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
●As there is a performance limit, the sys-
tem may not provide a warning in cer-
tain conditions.●The system will not detect the following
objects:
– Pedestrians, animals or obstacles in
the roadway
– Oncoming vehicles in the same lane
●The system will not detect another ve-
hicle under the following conditions:
– When the sensor area gets dirty and
it is impossible to detect the distance
from the vehicle ahead.– When the radar signal is temporarily
interrupted
●The system may not function properly
under the following conditions:
– A preceding vehicle is with a large
amount of ground clearance or pro-
truding freight (including a small ve-
hicle such as motorcycles) .
– When the sensor area of the front
bumper gets dirty or it is impossible
to detect the distance from the ve-
hicle ahead.
– When visibility is low (such as rain,
fog, snow, etc.) .
– When snow or road spray from trav-
eling vehicles is splashed.
– When excessively heavy baggage is
loaded in the rear seat or the luggage
room of your vehicle.
– When abruptly accelerating or
decelerating.
– On a steep downhill slope or on
roads with sharp curves.

– When there is a highly reflective ob-
ject near the vehicle ahead (for ex-
ample, being very close to another
vehicle, signboard, etc.)
– When you are towing a trailer.
●Depending on certain road conditions
(curved or beginning of a curve) , vehicle
conditions (steering position or vehicle
position) , or the preceding vehicle’s
conditions (position in lane, etc.) , the
system may not function properly. The
system may detect highly reflective ob-
jects such as signs and other stationary
objects on the road or near the traveling
lane and provide unnecessary warning.
●The system may not function in offset
conditions.
●The system may not function when the
distance to the vehicle ahead is ex-
tremely close.●The system is designed to automatically
check the sensor’s functionality. If the
sensor area of the front bumper is cov-
ered with ice, a transparent or translu-
cent bag, etc., the system may not de-
tect them. In these instances, the
system may not be able to warn the
driver properly. Be sure to check and
clean the sensor area of the front bum-
per regularly.
●Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
●A sudden appearance of a vehicle in
front (for example, it abruptly cuts in)
may not be detected and the system
may not warn the driver soon enough.
●The system will be cancelled automati-
cally with a beep sound and a message
will pop up under the following
conditions:
– When the sensor area of the front
bumper is dirty
– When the system malfunctionsIf the system cancels and a message pops up
with a beep sound, pull off the road to a safe
location, stop the vehicle and turn the engine off.
Check to see if the sensor area of the front
bumper is blocked. If the sensor area of the front
bumper is blocked, remove the object blocking
and restart the engine.
If the sensor is malfunctioning, have the system
checked by an INFINITI retailer.

The Intelligent Brake Assist (IBA) system warns
the driver by a warning light and chime when
there is a risk of a collision with the vehicle ahead
in the traveling lane and the driver must take
avoidance action immediately. The system helps
reduce the rear-end collision speed by applying
the brakes when the system judges that the col-
lision cannot be prevented.
The IBA system will function when your vehicle is
driven at speeds of approximately 10 MPH
(15 km/h) and above, and when your vehicle is
driven at speeds approximately 10 MPH
(15 km/h) faster than the vehicle ahead.
The IBA system uses a distance sensor
Alo-
cated behind the front bumper to measure the
distance to the vehicle ahead. When the system
judges that your vehicle is getting close to the
vehicle ahead in the traveling lane, the vehicle
ahead detection indicator light on the information
display blinks and a warning chime sounds.
The IBA system can be turned on/off by in the
settings of the vehicle information display, see
“Driving aids” in the “Instrument and controls”
section.PRECAUTIONS ON IBA SYSTEM
WARNING
●The IBA system is not a collision avoid-
ance system. It is the driver’s responsi-
bility to stay alert, drive safely and be in
control of the vehicle at all times.
