fuel filter INFINITI QX30 2018 Owners Manual

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage 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. Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the
engine is hot. Always turn off the engine
and wait until it cools down.
•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 any jewelry, such as
rings, watches, etc. before working on
your vehicle.
•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 by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•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.
•Always wear eye protection whenever
you work on your vehicle.
•Never leave the engine or the transmis-
sion related component harness connec-
tor disconnected while the ignition
switch is in the ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

Replace the spark plugs according to the
maintenance schedule shown in a separate
maintenance booklet.
If replacement is required, it is recommended
that you visit an INFINITI retailer.
Always replace spark plugs with recom-
mended or equivalent ones.
WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
•Be sure to use the correct socket to re-
move the spark plugs. An incorrect
socket can cause damage to the spark
plugs. It is recommended that you visit an INFINITI
retailer if checking or replacement is required.
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.
CLEANING
If the windshield or rear window is not clear
after using the window washer or if a wiper
blade chatters when running, wax or other
material may be on the blade or windshield.
Clean the outside of the windshield or rear
window with a washer solution or a mild
detergent. The windshield or rear window is
clean if beads do not form when rinsing with
clear water.
Clean the blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water. If
the windshield or rear window is still not clear
after cleaning the blades and using the wiper,
replace the blades.
CAUTION
Worn windshield wiper blades can damage
the windshield and impair driver vision.

RECOMMENDED FLUIDS/
LUBRICANTS AND CAPACITIES
10-2Technical information

Fuel containing MMT
MMT, or methylcyclopentadienyl manganese
tricarbonyl, is an octane boosting additive.
INFINITI does not recommend the use of fuel
containing MMT. Such fuel may adversely
affect vehicle performance, including the
emissions control system. Note that while
some fuel pumps label MMT content, not all
do, so you may have to consult your gasoline
retailer for more details.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel in-
jector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold com-
mercially. Many of these additives intended
for gum, varnish or deposit removal may con-
tain active solvent or similar ingredients that
can be harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rat-
ing lower than recommended above can
cause persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If severe,
this can lead to engine damage. If you detect
a persistent heavy spark knock even when
using gasoline of the stated octane rating, or
if you hear steady spark knock while holding
a steady speed on level roads, it is recom-mended you have an INFINITI retailer cor-
rect the condition. Failure to correct the con-
dition is misuse of the vehicle, for which
INFINITI is not responsible.
Incorrect ignition timing will result in knock-
ing, after-run and/or overheating. This in turn
may cause excessive fuel consumption or
damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended you visit an
INFINITI retailer.
However, now and then you may notice light
spark knock for a short time while accelerat-
ing or driving up hills. This is no cause for
concern, because you get the greatest fuel
benefit when there is light spark knock for a
short time under heavy engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure sat-
isfactory engine life and performance. For
additional information, refer to "Recom-
mended fluids/lubricants and capacities"
earlier in this section.
Select only engine oils that meet the
MB229.5 specification and SAE viscosity
standard. These oils have the MB229.5
specification label on the container. Oils
which do not have the specified quality label
should not be used as they could cause en-
gine damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant that the engine oil viscosity be selected
