2023 INFINITI QX60 check engine

• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire wear
and lowers fuel economy.
• Keep all the wheels in correct alignment. Improper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, see “Engine oil
and oil filter recommendations” (P. 10-6).
If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.
If the AWD error warning message is dis-
played, there may be a malfunction in the
Intelligent AWD system. Reduce vehicle
speed and have your vehicle checked as soon
as possible. It is recommended that you visit
an INFINITI retailer for this service. The AWD high temperature message may be
displayed when the oil temperature of the
powertrain parts increases due to the differ-
ence in rotation between the front and rear
wheels is large (wheel slip), such as when
driving on rough roads, driving through sand
or mud, or feeling a stuck vehicle. If this
warning is displayed, stop the vehicle with the
engine idling, as soon as it is safe to do so. In
these cases, the AWD changes to 2WD to
protect the powertrain parts. Then if the
warning turns off, you can continue AWD
driving.

The tire size message may be displayed if
there is a large difference between the diam-
eters of front and rear wheels and tires. Pull
off the road in a safe area, with the engine
idling. Check that all tire sizes, brand, con-
struction and tread pattern are the same, that
the tire pressures are correct and that the
tires are not excessively worn. If you have any
problems, change tires or adjust tire pres-
sures correctly. Do not select the SNOW
mode with the INFINITI Drive Mode Selector
and do not drive fast.If any warning messages continue to be dis-
played, have your vehicle checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.
WARNING
• Do not drive beyond the performance ca-
pability of the tires. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control, even
with Intelligent AWD engaged.
• For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any drive or
reverse position with the engine running.
Doing so may result in drivetrain damage
or unexpected vehicle movement which
could result in serious personal injury or
vehicle damage. •
Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious personal in-
jury or vehicle damage.
CAUTION
• Do not operate the engine on a free roller
when any of the wheels are raised.
• If you use the free roller, rotate four
wheels with the same speed without
raising any wheels.
• If an AWD warning message is displayed
while driving there may be a malfunction
in the AWD system. Reduce the vehicle
speed immediately and have your vehicle
checked as soon as possible. It is recom-
mended that you visit an INFINITI re-
tailer for this service.

•The powertrain may be damaged if you
continue driving with AWD error
warning on.
• If the AWD high temperature message is
displayed while you are driving, pull off
the road in a safe area, and idle the en-
gine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning message
turns off, you can drive again.
• If the tire size incorrect message is dis-
played while you are driving, pull off the
road in a safe area with the engine idling.
Check that all tire sizes are the same,
that the tire pressure is correct and that
the tires are not excessively worn.
• If a warning message continues to be dis-
played after the above operations, have
your vehicle checked as soon as possible.
It is recommended that you visit an
INFINITI retailer for this service.
When the vehicle is in the P (Park) position,
the operation noise may be heard from the
lower part of the vehicle. This is not a
malfunction.
WARNING
• Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
• Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park). Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shift
lever has been pushed as far forward as it
can go and cannot be moved without de-
pressing the foot brake pedal. •
Never leave the engine running while the
vehicle is unattended.
• Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or make the
vehicle move. Unattended children could
become involved in serious accidents.

•To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm day
can quickly become high enough to cause
a significant risk of injury or death to
people and pets.
1. Firmly apply the parking brake.
2. Push the park button to engage the P (Park) position.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, it is
a good practice to turn the wheels as
illustrated.
• HEADED DOWNHILL WITH CURB
OA:
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
• HEADED UPHILL WITH CURB
OB:
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb. •
HEADED UPHILL OR DOWNHILL, NO
CURB
OC:
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Place the ignition switch in the LOCK position.WARNING
• If the engine is not running or is turned
off while driving, the power assist for the
steering will not work. Steering will be
harder to operate.
• When the electric power steering
warning light illuminates with the engine
running, there will be no power assist for
the steering. You will still have control of
the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged.
While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will

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.

This procedure is described in the INFINITI
Service Manual. It is recommended that you
visit an INFINITI retailer for this service.
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

• If the sonar sensors are dirty, wipe them offwith a soft cloth while being careful to not
damage them.
• The sonar sensors may be blocked by tem- porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the sonar sen-
sors. Check for and remove objects ob-
structing the area around the sonar
sensors.
• Do not subject the area around the sonar sensors to strong impact. Also, do not re-
move or disassemble the sonar sensors. If
the sonar sensors and peripheral areas are
deformed in an accident, etc., have the so-
nar sensors checked by an INFINITI retailer.
• Do not attach stickers (including transpar- ent material), install accessories or apply
additional paint on the sonar sensors and
their surrounding areas. This may cause a
malfunction or improper operation.
• When washing the vehicle using a high- pressure washer, do not apply direct
washer pressure on the sonar sensors. This
may cause a malfunction of the sonar
sensors. The Idling Stop System activates to prevent
unnecessary fuel consumption, exhaust
emissions and noise.
• When you stop the vehicle, the engine is
turned off automatically.
• When you release the brake pedal to begin moving again, the engine is turned on
automatically.
WARNING
The engine restarts if the vehicle moves at
approximately 1 mph (2 km/h) or more (on
a downhill grade, etc.) while the engine is
turned off by the Idling Stop System. De-
press the brake pedal immediately to stop
the vehicle to prevent an accident.
CAUTION
At the end of the journey the engine must
be stopped and ignition switch be pushed
off. Lock the vehicle as normal. Pushing the
ignition switch off will shut down all elec-
trical systems. Failure to do this may result
in a discharged battery.
NOTE:
The Idling Stop System will not activate un-
der the following conditions:
• When the engine is kept idling without the
vehicle being driven after the engine is
turned on.
• When the engine coolant temperature is
low.
• When the battery capacity is low.
• When the battery temperature is low.
• When the vehicle is moving.
• When a negative pressure booster
decreases.
• When the engine hood is opened with the
engine running.
• When the engine is turned on with the en-
gine hood open.
• When the driver’s seat belt is not fastened.
• When the driver’s door is open.
• When the steering wheel is operated.
• When the Idling Stop System indicator
blinks at a low speed.
•
When the fan speed control is in any position
other than “OFF,” (0) while the air flow con-
trol is in the front defogger position.
• When the front defroster switch is on.
IDLING STOP SYSTEM

•When the temperature inside the vehicle is
higher than approximately 86°F (30°C),
unless the Air Conditioning ECO custom-
ize option is selected, and the ECO driving
mode is on. (When the air conditioner is
off, the Idling Stop System will operate.)
• When the front defroster is turned on.
• When more than 3 minutes have elapsed
since the Idling Stop System was active.
• When the accelerator pedal is depressed.
• When the steering wheel is operated. (The
steering wheel operation may become
heavy, but this is not a malfunction.)
• When the battery capacity is low.
• When the power consumption is high.
• When the shift lever is any range other
than D (Drive).
• When the Idling Stop OFF switch is
pushed.
• When the negative pressure of the brake
system is not sufficiently applied by de-
pressing the brake pedal several times.
NOTE:
The Idling Stop System may not active when
the Intelligent Key is not in the vehicle and
you open/close any door.
NOTE:
The following condition will prevent the
Idling Stop System from automatically re-
starting the engine. Starting the engine with
the ignition switch operation is then
necessary:
• The hood is open.
Use this system while waiting at a stop light,
etc. When the vehicle is stopped for long
periods of time, turn off the engine.
When the engine is stopped by the Idling Stop
System, heating, cooling and dehumidifying
functions will be deactivated. To avoid the air
conditioning functions from being deacti-
vated, turn off the Idling Stop System by
pushing the Idling Stop OFF switch.
RETROGRADE MOVEMENT
CONTROL FUNCTION
This system is designed to reduce the retro-
grade movement that occurs while the driv-
er’s foot changes from depressing the brake
pedal to the accelerator pedal when moving
the vehicle while the Idling Stop System is
active on a hilly road.
IDLING STOP SYSTEM DISPLAY
The status of the Idling Stop System can be
checked in the vehicle information display.
