sensor INFINITI QX60 2015 Repair Manual

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
button to enter the “Set-
tings” menu in the vehicle information dis-
play, then select using the ENTER button.
2. Use the
buttons to select “Driver As-
sistance”, then press the ENTER button.
3. Use the
buttons to select “Intelligent
Brake Assist”, using the ENTER button the
system can be turned on or off. The IBA system will remain in the last ON or OFF
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:

WARNING
●Always turn and look back before back-
ing up. The rear sonar system is not a
substitute for proper backing
procedures.
● Always look around before proceeding.
The front sonar system is not a substi-
tute for proper driving procedures. ●
Read and understand the limitations of
the front and rear sonar system as con-
tained in this section. Inclement
weather may affect the function of the
sonar system, this may include reduced
performance or a false activation.
● This system is not designed to prevent
contact with small or moving objects. ●
The system is designed as an aid to the
driver in detecting large stationary ob-
jects to help avoid damaging the ve-
hicle. The system will not detect small
objects below the bumper, and may not
detect objects close to the bumper or
on the ground.
● If your vehicle sustains damage to the
front bumper fascia or the rear bumper
fascia, leaving it misaligned or bent, the
sensing zone may be altered causing
inaccurate measurement of obstacles
or false alarms.
The Rear Sonar System sounds a tone to warn
the driver of obstacles near the rear bumper. The
Rear Sonar System automatically turns on when
the shift lever is placed in R (Reverse) and the
ignition is ON. The system may not detect objects
at speeds above 3 MPH (5 km/h) and may not
detect certain angular or moving objects.
The Rear Sonar System detects obstacles up to
5.9 feet (1.8 meters) from the rear bumper with a
decreased coverage area at the outer corners of
the bumper, (refer to the illustration for approxi-
mate zone coverage areas) . As you move closer
to the obstacle, the rate of the tone increases.
When the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound continuously.

than 10 inches (25.0 cm) from the side of the
vehicle, the tone will sound for only 3 seconds.
Once the system detects an object approaching,
the tone will sound again.
The Front Sonar System sounds a tone to warn
the driver of obstacles near the front bumper. The
front sonar system automatically turns on when
the shift lever is placed in a forward gear and the
ignition switch is in the ON position. The system
may not detect objects at speeds above 3 MPH
(5 km/h) and may not detect certain angular or
moving objects.
The Front Sonar System detects obstacles up to
3 feet (1.0 m) from the front bumper with a
decreased coverage area at the outer corners of
the bumper, (refer to the illustration for approxi-
mate zone coverage areas) . As you move closer
to the obstacle, the rate of the tone increases.
When the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound continuously.
If it detects a stationary or receding object further
than 10 inches (25.0 cm) from the side of the
vehicle, the tone will sound for only 3 seconds.
Once the system detects an object approaching,
the tone will sound again.The front and rear sonar system OFF switch on
the instrument panel allows the driver to turn the
sonar system on and off. To turn the system off,
the ignition must be ON, and the shift lever in R
(Reverse) or D (Drive) . An indicator light on the
switch will illuminate when the system is turned
off. If the indicator light illuminates when the
system is not turned off, it may indicate a failure in
the sonar system.
Keep the front and rear sonar sensors (located on
the bumper fascia) free from snow, ice and large
accumulations of dirt (do not clean the sensors
with sharp objects) . If the sensors are covered, it
will affect the accuracy of the sonar system.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever is in
the D (Drive) position and both front and rear
obstacles when the shift lever is in the R (Re-
verse) position.

The system is deactivated at speeds above
6 MPH (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after 3 seconds
when an obstacle is detected by only the corner
sensor and the distance does not change. The
tone will stop when the obstacle get away from
the vehicle.
When the object is detected, the indicator
(green) appears and blinks and the tone sounds
intermittently. When the vehicle moves closer to
the object, the color of the indicator turns yellow
and the rate of the blinking increase. When the
vehicle is very close to the object, the indicator
stops blinking and turns red, and the tone sounds
continuously.
Starting and driving5-103

To shut off the engine in an emergency situation
while driving, perform the following procedure:
– Rapidly push the push-button ignition switchthree consecutive times in less than 1.5 sec-
onds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It monitors
tire pressure of all tires except the spare. When
the low tire pressure warning light is lit, and the
“Tire Pressure Low - Add Air” warning appears in
the vehicle information display, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will acti-
vate and warn you of it by the low tire pressure
warning light. This system will activate only when
the vehicle is driven at speeds above 16 mph
(25 km/h). For additional information, refer to
“Warning/indicator lights and audible reminders”
in the “Instruments and controls” section and
“Tire Pressure Monitoring System (TPMS)” in the
“Starting and driving” section of this manual.
WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use. ●
If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal in-
jury. Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible.
● When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon
as possible for tire replacement and/or
system resetting.
EMERGENCY ENGINE SHUT OFF FLAT TIRE
In case of emergency6-3

●Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
WARNING
●Make sure the parking brake is securely
applied and the CVT is shifted into P
(Park) .
● Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.
A. Blocks
B. Flat tire
Blocking wheels
Place suitable blocks at both the front and back
of the wheel diagonally opposite the flat tire to
prevent the vehicle from moving when it is jacked
up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.

6-4In case of emergency

Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft bristled brush. Wipe the vinyl and
leather surfaces with a clean, soft cloth damp-
ened in mild soap solution, then wipe clean with a
dry, soft cloth.
Regular care and cleaning is required in order to
maintain the appearance of the leather.
Before using any fabric protector, read the manu-
facturer’s recommendations. Some fabric pro-
tectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water to clean
the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification
sensor. This can also affect the operation
of the air bag system and result in serious
personal injury.
CAUTION
●Never use benzine, thinner or any simi-
lar material. ●
Small dirt particles can be abrasive and
damaging to leather surfaces and
should be removed promptly. Do not
use saddle soap, car waxes, polishes,
oils, cleaning fluids, solvents, deter-
gents or ammonia-based cleaners as
they may damage the leather’s natural
finish.
● Never use fabric protectors unless rec-
ommended by the manufacturer.
● Do not use glass or plastic cleaner on
meter or gauge lens covers. It may dam-
age the lens cover.
AIR FRESHENERS
Most air fresheners use a solvent that could affect
the vehicle interior. If you use an air freshener,
take the following precautions:
● Hanging-type air fresheners can cause per-
manent discoloration when they contact ve-
hicle interior surfaces. Place the air fresh-
ener in a location that allows it to hang free
and not contact an interior surface.
● Liquid-type air fresheners typically clip on
the vents. These products can cause imme-
diate damage and discoloration when
spilled on interior surfaces. Carefully read and follow the manufacturer’s in-
structions before using the air fresheners.
POWER MOONROOF
The moonroof is made from a suede material.
CAUTION
To help prevent damaging the moonroof
while cleaning:
●
Do not rub the material with a cloth.
Doing so can damage the surface of the
material or cause a stain to spread.
● Never use benzine, thinner or any simi-
lar chemical to clean the suede. This
may discolor the moonroof and damage
the surface.
● Clean water based stains by patting the
surface with a clean soft cloth damp-
ened in warm water. Press a clean dry
cloth onto the surface to remove as
much dampness as possible and then
let air dry.
● Clean oil based stains by patting the
surface with a clean soft cloth damp-
ened in warm water. Press a clean dry
cloth onto the surface to remove as
much dampness as possible and then
let air dry.
