2015 INFINITI QX60 sensor

●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 malfunctions
If the system cancels and a message appears
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.
FCW SYSTEM OPERATION
The FCW system is active at speeds of approxi-
mately 10 MPH (15 km/h) and above, when the
system turns on.
The warning systems switch is used to turn on
and off the FCW system when it is activated
using the settings menu on the information dis-
play. For additional information, refer to “How to
enable/disable the FCW system” using the set-
tings menu in this section.

– To turn on the system, use the ENTER button to check box for “Assistance
(DCA)” 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.
INTELLIGENT BRAKE ASSIST (IBA)
SYSTEM (if so equipped)
Starting and driving5-85

The IBA system uses a distance sensorAlo-
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. For
additional information, refer to “Driving aids” in
the “Instrument and controls” section of this
manual.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.
● As there is a performance limit, the sys-
tem may not provide a warning or brak-
ing in certain conditions.
● The system will not detect the following
objects:
– Pedestrians, animals or obstacles in the roadway – Oncoming vehicles in the same lane
● The sensor generally detects the sig-
nals returned from the vehicle ahead.
Therefore, the system may not function
properly under the following
conditions:
– When the sensor area of the front bumper gets dirty and it is impos-
sible to detect the distance from the
vehicle ahead.
– When radar signal is temporarily interrupted.
– 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.

5-86Starting and driving

– 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 objects 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.
WARNING
●In extreme conditions, detection of
these objects may cause the system to
function. ●
The system is designed to automatically
check the sensor’s functionality. When
the sensor detects an obstruction of the
radar signals due to dirt, adhesive ma-
terial, or similar objects to the front
bumper, the system will automatically
cancel. However, sensor may not detect
all obstructive material. In these in-
stances the system may not be able to
warn the driver properly. Be sure to
check and clean the sensor area of the
front bumper 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 the IBA
warning light will illuminate under the
following conditions:
– When the sensor area of the front bumper is dirty
– When the system malfunctions

If the IBA OFF indicator light illuminates 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 dirty.
If the sensor area of the front bumper is dirty,
clean it with a soft cloth and restart the engine. If
the sensor area of the front bumper is not dirty,
restart the engine. If the IBA OFF indicator light
continues to illuminate even if the IBA system is
turned on, have the system checked by an
INFINITI retailer.
IBA SYSTEM OPERATION
The IBA system will function when your vehicle is
driven at speeds of approximately 10 MPH
(15 km/h) or above, and when the vehicle’s
speed is approximately 10 MPH (15 km/h) faster
than that of the vehicle ahead.
To turn the system on/off:1. Push the

state it was left in until it is changed in the vehicle
information display. For additional information,
refer to “Driver Assistance” in the “Instrument and
controls” section of this manual.
Illumination of the IBA OFF indicator light without
the warning chime sound is an indication that the
IBA system is temporarily unavailable. It will occur
under the following conditions:
When the radar signal is temporarily interrupted.
The IBA OFF indicator light will turn off when the
system returns to its normal operating conditions.
For the sensor maintenance, refer to “Intelligent
Cruise Control (ICC) system (Full speed range)”
in this section.
CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle. Failure to follow these rec-
ommendations may result in shortened
engine life and reduced engine
performance.
● Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 RPM.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 mi
(805 km) . Your engine, axle or other parts
could be damaged.
BREAK-IN SCHEDULE
5-88Starting and driving

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h). The speed varies according to road
conditions.When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. it is the driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
PREVIEW FUNCTION (Intelligent
Cruise Control system equipped
models)
When the Preview Function identifies the need to
apply emergency braking by sensing a vehicle
ahead in the same lane and the distance and
relative speed from it, it applies the brake pre-
pressure before the driver depresses the brake
pedal and helps improve brake response by re-
ducing pedal free play.
● This system will not operate when the ve-
hicle is moving at approximately 32 km/h
(20 MPH) or less.
● The pre-pressure function ceases when the
following conditions are met:
1. When the driver depresses the accelerator pedal or the brake pedal.
2. If the driver does not operate the accelerator or brake pedal within approximately 1 sec-
ond.
5-96Starting and driving

●The sensor will not detect:
1. Pedestrians or objects in the roadway
2. Oncoming vehicles in the same lane
3. Motorcycles traveling offset in the travel lane as illustrated
WARNING
●This system is only an aid to assist brak-
ing operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times. ●
As there is a performance limit to the
Preview Function, never rely solely on
this system. This system does not cor-
rect careless inattentive or absent-
minded driving, or overcome poor vis-
ibility in rain, fog, or other bad weather.
Reduce vehicle speed by depressing the
brake pedal, in order to maintain a safe
distance between vehicles.
● The system may not detect the vehicle
in front of you in certain road or weather
conditions. The Preview Function may
not operate properly under the follow-
ing conditions. The vehicle is still drive-
able under normal conditions and the
Brake Assist will operate.
– When rain, snow or dirt adhere to the system sensor
– When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle
– Winding or hilly roads may cause the sensor to temporarily not detect a
vehicle in the same lane or may de-
tect objects or vehicles in other
lanes. – Vehicle position in the lane may
cause the sensor to temporarily not
detect a vehicle in the same lane or
may detect objects or vehicles in
other lanes.

Warning light and display
When the Preview Function is not operating
properly, the chime sounds and the system warn-
ing light (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 resume driving.
If the indicator stays on, it may indicate that
the Preview Function is malfunctioning
(the brake is operative) . Although the ve-
hicle is still driveable under normal condi-tions, have the vehicle checked at an
INFINITI retailer.
How to handle the sensor
The sensor for the Preview Function is common
with the ICC and is located below the front
bumper.
To keep the Preview Function operating properly,
be sure to observe the following:
● Always keep the area around the sensor
clean.
● Do not strike or damage the areas around
the sensor.
● Do not touch or remove the screw located
on the sensor. Doing so could cause failure
or malfunction. If the sensor is damaged due
to an accident, contact an INFINITI retailer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion. The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving conditions,
the VDC System helps to perform the following
functions:
● Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.
When the VDC system operates, the
indi-
cator in the instrument panel flashes to note the
following:
