ESP INFINITI QX60 2023 Service Manual

Before customizing or restoring the front
bumper, it is recommended that you visit an
INFINITI retailer.
The camera sensor is located above the in-
side mirror.
To keep the proper operation of the systems
and prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar-ent material) or install an accessory near
the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit an
INFINITI retailer.STEERING ASSIST
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the Steering Assist
could result in serious injury or death.
• The Steering Assist is not a replacement
for proper driving procedures and is not
designed to correct careless, inattentive
or absent-minded driving. The Steering
Assist will not always steer the vehicle to
keep it in the lane. It is not designed to
prevent loss of control. It is the driver’s
responsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.
• As there is a performance limit to the
Steering Assist’s capability, never rely
solely on the system. The Steering Assist
does not function in all driving, traffic,
weather, and road conditions. Always
drive safely, pay attention to the opera-
tion of the vehicle, and manually control
your vehicle appropriately.
• The Steering Assist is intended for use on
well-developed freeways or highways
with gentle (moderate) curves. To avoid
risk of an accident, do not use this system
on local or non-highway roads. •
The Steering Assist only steers the ve-
hicle to maintain its position in the center
of a lane. The vehicle will not steer to
avoid objects in the road in front of the
vehicle or to avoid a vehicle moving into
your lane.
• It is the driver’s responsibility to stay
alert, drive safely, keep the vehicle in the
traveling lane, and be in control of the
vehicle at all times. Never take your
hands off the steering wheel when driv-
ing. Always keep your hands on the
steering wheel and drive your vehicle
safely.
• Always drive carefully and attentively
when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering As-
sist. To avoid serious injury or death, do
not rely on the system to prevent acci-
dents or to control the vehicle’s speed in
emergency situations. Do not use the
Steering Assist except in appropriate
road and traffic conditions.
Starting and driving5-111

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

CONVENTIONAL (fixed speed)
CRUISE CONTROL MODE
NOTE:
ProPILOT Assist provides no approach
warnings, automatic braking, or steering as-
sist in the conventional (fixed speed) cruise
control mode.
This mode allows driving at a speed between
25 to 90 mph (40 to 144 km/h) without
keeping your foot on the accelerator pedal.
WARNING
• In the conventional (fixed speed) cruise
control mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the pres-
ence of the vehicle ahead nor the vehicle-
to-vehicle distance is detected.
• Pay special attention to the distance be-
tween your vehicle and the vehicle ahead
of you or a collision could occur.
• Always confirm the setting in the ICC
system display.
• Do not use the conventional (fixed
speed) cruise control mode when driving
under the following conditions:
– When it is not possible to keep the
vehicle at a set speed
– In heavy traffic or in traffic that var-
ies in speed
– On winding or hilly roads
–
On slippery roads (rain, snow, ice, etc.)
– In very windy areas
• Doing so could cause a loss of vehicle
control and result in an accident.

• Do not install any stickers (including trans-parent stickers) or accessories on the park-
ing sensors
O1and their surrounding areas.
This may cause a malfunction or improper
operation.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the FEB with Pedes-
trian Detection system could result in seri-
ous injury or death.
• The FEB with Pedestrian Detection sys-
tem is a supplemental aid to the driver. It
is not a replacement for the driver’s at-
tention to traffic conditions or responsi-
bility to drive safely. It cannot prevent
accidents due to carelessness or danger-
ous driving techniques.
• The FEB with Pedestrian Detection sys-
tem does not function in all driving, traf-
fic, weather and road conditions.
The FEB with Pedestrian Detection system
can assist the driver when there is a risk of a
forward collision with the vehicle ahead in the
traveling lane or with a pedestrian ahead in
the traveling lane. The FEB with Pedestrian Detection system
uses a radar sensor located on the front of
the vehicle
OBto measure the distance to the
vehicle ahead in the same lane. For pedestri-
ans, the FEB with Pedestrian Detection sys-
tem uses a camera installed behind the wind-
shield

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DAA system
could result in serious injury or death.
• The DAA system is only a warning to in-
form the driver of a potential lack of
driver attention or drowsiness. It will not
steer the vehicle or prevent loss of
control.
• The DAA system does not detect and
provide an alert of the driver’s lack of
attention or fatigue in every situation.
• It is the driver’s responsibility to:
– stay alert,
– drive safely,
– keep the vehicle in the traveling lane,
– be in control of the vehicle at all times,
– avoid driving when tired,
– avoid distractions (texting, etc.). The DAA system helps alert the driver if the
system detects a lack of attention or driving
fatigue.
The system monitors driving style and steer-
ing behavior over a period of time, and it
detects changes from the normal pattern. If
the system detects that driver attention is
decreasing over a period of time, the system
uses audible and visual warnings to suggest
that the driver take a break.
DRIVER ATTENTION ALERT (DAA)
(if so equipped)
5-156Starting and driving

return to normal. Avoid repeating such steer-
ing wheel operations that could cause the
power steering system to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the electric power steering warning light
illuminates while the engine is running, it may
indicate the power steering system is not
functioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the electric power steering warning
light illuminates with the engine running,
there will be no power assist for the steering,
but you will still have control of the vehicle. At
this time, greater steering effort is required to
operate the steering wheel, especially in
sharp turns and at low speeds.
For additional information, see “Electric
power steering warning light” (P. 2-17).The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle and stopping distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.
WARNING
• While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
• If the engine is not running or is turned
off while driving, the power assist for the
brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result,
your braking distance will be longer and the
vehicle may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or rotors are replaced, in order to
assure the best brake performance.
BRAKE SYSTEM
Starting and driving5-165

Normal operation
The Anti-lock Braking System (ABS) operates
at speeds above3-6mph(5-10km/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 applies and releases hydraulic pres-
sure. 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 prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional 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-
er’s responsibility to stay alert, drive safely
and be in control of the vehicle at all times. • The ABLS system uses automatic braking
to transfer power from a slipping drive
wheel to the wheel on the same axle with
more traction. The ABLS system applies
braking to the slipping wheel, which helps
redirect power to the other wheel.
• The ABLS system is always on. In some conditions, the system may automatically
turn the ABLS system off. If the system is
automatically turned off, normal brake
function will continue. ABLS will function
even when the Vehicle Dynamic Control
system is turned off.
• The ABLS does not operate if both wheels on a drive axle are slipping.
WARNING
• The ABLS system helps provide in-
creased traction, but will not prevent ac-
cidents due to abrupt steering operation
or by careless driving or dangerous driv-
ing practices. Reduce vehicle speed and
be especially careful when driving and
cornering on slippery surfaces. Always
drive carefully.
ACTIVE BRAKE LIMITED SLIP (ABLS)
SYSTEM
Starting and driving5-167

•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.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-168Starting and driving

WARNING
• The VDC system is designed to help the
driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving tech-
niques. Reduce vehicle speed and be es-
pecially careful when driving and corner-
ing on slippery surfaces and always drive
carefully.
• 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
recommended for your vehicle or are ex-
tremely deteriorated, the VDC system
may not operate properly. This could ad-
versely affect vehicle handling perfor-
mance, and the
indicator light may
flash or both theandindicator
lights may illuminate.
• If brake related parts such as brake pads,
rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the VDC system may not operate
properly and both the
and theindicator lights may illuminate. •
If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate.
• When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly
and the
indicator light may flash or
both theandindicator lights
may illuminate. Do not drive on these
types of roads.
• When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may flash
or both theandindicator
lights may illuminate. This is not a mal-
function. Restart the engine after driv-
ing onto a stable surface.
• If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the
indicator light may flash or both
theandindicator lights may
illuminate.
• The VDC system is not a substitute for
winter tires or tire chains on a snow cov-
ered road. The chassis control is an electric control mod-
ule that includes the following functions:
• Active Trace Control
• Active Ride Control (if so equipped)
ACTIVE TRACE CONTROL
This system senses driving based on the driv-
er’s steering and acceleration/braking pat-
terns, and controls brake pressure at indi-
vidual wheels to aid tracing at corners and
help smooth vehicle response.
When the PERSONAL mode is selected, the
Active Trace Control can be set to ON (en-
abled) or OFF (disabled). For additional infor-
mation see “INFINITI Drive Mode Selector”
(P. 5-29).
When the VDC system is turned off, the Ac-
tive Trace Control is also turned off.
Amount of brake control is changed depend-
ing on the mode selected by the INFINITI
Drive Mode Selector.
When the Active Trace Control is not func-
tioning properly, the master warning light il-
luminates, and the warning message “Chassis
Control System Error” will also appear in the
vehicle information display.
