2023 INFINITI QX60 brake sensor

•Always check surroundings before re-
starting the vehicle.
• Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance.
The ICC system may not be able to main-
tain the selected distance between ve-
hicles (following distance) or selected
vehicle speed under some circumstances.
• The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the ICC system under the following con-
ditions:
– On roads with heavy, high-speed
traffic or 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
bumper around the distance sensor
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads –
When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources.
• Do not use the ICC system if you are
towing a trailer. The system may not de-
tect a vehicle ahead.
• In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert
and avoid using the ICC system where
not recommended in this warning
section.
The ICC system will not detect the following
objects:
• Stationary or slow moving vehicles
• Pedestrians or objects in the roadway
• Oncoming vehicles in the same lane
• Motorcycles traveling offset in the travel lane
The following are some conditions in which
the radar sensor cannot properly detect a
vehicle ahead and the system may not oper-
ate properly: • When the sensor detection is reduced (con-
ditions such as rain, snow, fog, dust storms,
sandstorms, and road spray from other
vehicles)
• Driving on a steep downhill slope or roads with sharp curves
• Driving on a bumpy road surface, such as an uneven dirt road
• If dirt, ice, snow or other material is cover- ing the radar sensor area
• A complicated-shaped vehicle such as a car carrier trailer or flatbed truck/trailer is near
the vehicle ahead.
• Interference by other radar sources
• When your vehicle is towing a trailer, etc.
• When excessively heavy baggage is loaded in the rear seat or cargo area of your
vehicle.
The ICC system is designed to automatically
check the radar sensor’s operation within the
limitations of the system.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the detec-
tion zone for the ICC system to maintain the
selected distance from the vehicle ahead. A
vehicle ahead may move outside of the de-
tection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are

Starting and driving5-109

If the driver does not operate the steering
wheel after the warning has been displayed,
an audible alert sounds and the warning
flashes in the vehicle information display, fol-
lowed by a quick brake application to request
the driver to take control of the vehicle again.
If the driver still does not respond, the ProPI-
LOT Assist turns on the hazard flasher and
slows the vehicle to a complete stop.
The driver can cancel the deceleration at any
time by steering, braking, accelerating, or op-
erating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for hands-
free driving. Always keep your hands on
the steering wheel and drive your vehicle
safely. Failure to do so could cause a colli-
sion resulting in serious personal injury or
death.
NOTE:
If the driver lightly touches (instead of firmly
grips) the steering wheel, the steering
torque sensor may not detect the driver’s
hand(s) on the wheel and a sequence of
warnings may occur. When the driver holds
and operates the steering wheel again, the
warnings turn off.
Steering Assist limitations
WARNING
• In the following situations, the camera
may not detect lane markers correctly or
may detect lane markers incorrectly and
the Steering Assist may not operate
properly:
– When driving on roads where there
are multiple parallel lane markers,
lane markers that are faded or not
painted clearly, nonstandard lane
markers, or lane markers covered
with water, dirt, snow, etc.
– When driving on roads with discon-
tinued lane markers
– When driving on roads with a widen-
ing or narrowing lane width
– When driving on roads where there
are multiple lanes or unclear lane
markers due to road construction
– When driving on roads where there
are sharply contrasting objects, such
as shadows, snow, water, wheel ruts,
seams, or lines remaining after road
repairs (the Steering Assist could de-
tect these items as lane markers)
– When driving on roads where the
traveling lane merges or separates •
Do not use the Steering Assist under the
following conditions because the system
may not properly detect lane markers.
Doing so could cause a loss of vehicle
control and result in an accident.
– During bad weather (rain, fog, snow,
dust, etc.)
– When rain, snow, sand, etc., is thrown
up by the wheels of other vehicles
– When dirt, oil, ice, snow, water, or an-
other object adheres to the camera
unit
– When the lens of the camera unit is
foggy
– When strong light (for example, sun-
light or high beams from oncoming
vehicles) shines on the camera
– When the headlights are not bright
due to dirt on the lens or the head-
lights are off in tunnels or darkness
– When a sudden change in brightness
occurs (for example, when the vehicle
enters or exits a tunnel or is under a
bridge)
–
When driving on roads where the trav- eling lane merges or separates or
where there are temporary lane mark-
ers because of road construction

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the RAB system
could result in serious injury or death.
• The RAB system is a supplemental aid to
the driver. It is not a replacement for
proper driving procedures. Always use
the side and rear mirrors and turn and
look in the direction you will move before
and while backing up. Never rely solely
on the RAB system. It is the driver’s re-
sponsibility to stay alert, drive safely,
and be in control of the vehicle at all
times.
• There is a limitation to the RAB system
capability. The RAB system is not effec-
tive in all situations.
• Inclement weather or ultrasonic sources
such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
The RAB system can assist the driver when
the vehicle is backing up and approaching
objects directly behind the vehicle. The RAB system detects obstacles behind
the vehicle using the parking sensors
O1lo-
cated on the rear bumper.
NOTE:
You can temporarily cancel the sonar func-
tion and the RAB system in the vehicle. For
additional information, see “Front and Rear
Sonar System” (P. 5-172).

–Low objects
– Narrow objects
– Wedge-shaped objects
– Objects close to the bumper (less than
approximately 1 ft [30 cm])
– Objects that suddenly appear
– Thin objects such as rope, wire, chain,
etc.
• The RAB system may not operate for the
following obstacles:
– Obstacles located high off the ground
– Obstacles in a position offset from
your vehicle
– Obstacles, such as spongy materials
or snow, that have soft outer sur-
faces and can easily absorb a sound
wave
• The RAB system may not operate in the
following conditions:
– There is rain, snow, ice, dirt, etc., at-
tached to the sonar sensors.
– A loud sound is heard in the area
around the vehicle.
– The surface of the obstacle is diago-
nal to the rear of the vehicle. •
The RAB system may unintentionally op-
erate in the following conditions:
– There is overgrown grass in the area
around the vehicle.
– There is a structure (e.g., a wall, toll
gate equipment, a narrow tunnel, a
parking lot gate) near the side of the
vehicle.
– There are bumps, protrusions, or
manhole covers on the road surface.
– The vehicle drives through a draped
flag or a curtain.
– There is an accumulation of snow or
ice behind the vehicle.
– An ultrasonic wave source, such as
another vehicle’s sonar, is near the
vehicle.
• Once the automatic brake control oper-
ates, it does not operate again if the ve-
hicle approaches the same obstacle.
• The automatic brake control can only
operate for a short period of time. There-
fore, the driver must depress the brake
pedal.
• In the following situations, the RAB sys-
tem may not operate properly or may not
function sufficiently:
– The vehicle is driven in bad weather
(rain, fog, snow, etc.). –
The vehicle is driven on a steep hill.
– The vehicle’s posture is changed (e.g.,
when driving over a bump).
– The vehicle is driven on a slippery
road.
– The vehicle is turned sharply by turn-
ing the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than INFINITI
recommended are used.
– The brakes are cold at low ambient
temperatures or immediately after
driving has started.
– The braking force becomes poor due
to wet brakes after driving through a
puddle or washing the vehicle.
• Turn the RAB system off in the following
conditions to prevent the occurrence of
an unexpected activatioin resulting from
sudden system operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed
truck.
– The vehicle is on the chassis
dynamometer.
– The

vehicle drives on an uneven road
surface.

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
• The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always main-
tain a safe distance from the vehicle in
front of you. Ultimately, the driver is re-
sponsible for safety.
• Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels. –
When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, see “Tire and Loading In-
formation label” (P. 8-30).
– For additional information, see
“Wheels and tires” (P. 8-28).
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking
on slippery surfaces. The system detects the
rotation speed at each wheel and varies the
brake fluid pressure to prevent each wheel
from locking and sliding. By preventing each
wheel from locking, the system helps the
driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to pre-
vent the wheels from locking up. Steer the
vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The Anti-lock Braking System (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 malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then op-
erates normally but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the vehicle
checked. It is recommended that you visit an
INFINITI retailer for this service.
5-166Starting and driving

•Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
approved for your vehicle or are ex-
tremely deteriorated, the ABLS system
may not operate properly. This could ad-
versely affect vehicle handling perfor-
mance, and the slip indicator light may
illuminate.
• If brake related parts such as brake pads,
rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the ABLS system may not operate
properly and the slip indicator light may
illuminate.
• If wheels or tires other than the INFINITI
recommended ones are used, the ABLS
system may not operate properly and
the slip indicator light may illuminate. The VDC system uses various sensors to
monitor driver inputs and vehicle motion. Un-
der certain driving conditions, the VDC sys-
tem 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 fol-
lowing conditions:– 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 main-
tain control of the vehicle, but it cannot prevent
loss of vehicle control in all driving situations.
When the VDC system operates, theindicator light in the instrument panel flashes
to note the following:
• The road may be slippery or the system may determine some action is required to help
keep the vehicle on the steered path. • You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
• Adjust your speed and driving to the road conditions.
For additional information, see “Slip indicator
light” (P. 2-20) and ”Vehicle Dynamic Control
(VDC) OFF indicator light” (P. 2-20).
If a malfunction occurs in the system, the
andindicator lights come on in the
instrument panel. The VDC system automati-
cally turns off when these indicator lights are
on.
The vehicle information display is used to turn
off the VDC system. The
indicator light
and the FEB with Pedestrian Detection sys-
tem warning light illuminate to indicate the
VDC system is off.
When the vehicle information display is used
to turn off the system, the VDC system still
operates to prevent one drive wheel from
slipping by transferring power to a non-
slipping drive wheel. The
indicator light
flashes if this occurs. All other VDC functions
are off and the
indicator light will not
flash.
