2023 INFINITI QX60 fuel filter

• 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.

When performing any inspection or maintenance
work on your vehicle, always take care to pre-
vent serious accidental injury to yourself or dam-
age to the vehicle. The following are general
precautions which should be closely observed.
WARNING
• Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Push the park button to engage the
P (Park) position.
• Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
• It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
• Always wear eye protection whenever
you work on your vehicle.
• Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
• If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
• Never get under the vehicle while it is
supported only by a jack. If it is necessary
to work under the vehicle, support it
with safety stands.
•
Keep smoking materials, flame and sparks
away from the fuel tank and battery.
• Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
• Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
• Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid. •
Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
• Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, see
“Owner’s Manual/Service Manual order in-
formation” (P. 10-36).
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

WARNING
• Operating the engine with the air cleaner
filter off can cause you or others to be
burned. The air cleaner filter not only
cleans the intake air, it also stops the
flame if the engine backfires. If the air
cleaner is not installed and the engine
backfires, you could be burned. Never
drive with the air cleaner filter off. Be
cautious working on the engine when the
air cleaner is off. •
Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result in
serious injury.
To remove the filter from the air cleaner, push
the tabs
OAand pull the cover upward.
The dry paper type filter element may be
cleaned and reused. Replace the air filter ac-
cording to the maintenance log shown in the
“Maintenance and schedules” section of this
manual.
When replacing the air filter, wipe the inside
of the air cleaner housing and the cover with
a damp cloth.
NOTE:
After installing a new air cleaner filter,
make sure the air cleaner cover is seated in
the housing and latch the clips
OA.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry of
airborne dust and pollen particles and re-
duces some objectionable outside odors. The
filter is located behind the glove box. See the
"Maintenance and schedules" section of this
manual for change intervals.
If replacement is required, it is recommended
that you visit an INFINITI retailer for this
service.
