Infiniti QX50/EX (2017 year). Manual — part 30
(475,1)
Model: 2017MY INFINITI QX50(J50) OM17E00J50U0 ]
To help ensure smooth, safe and economic-
al driving, INFINITI provides two mainte-
nance schedules that may be used,
depending upon the conditions in which
you usually drive. These schedules contain
both distance and time intervals, up to
120,000 miles (192,000 km)/144 months.
For most people, the odometer reading will
indicate when service is needed. However,
if you drive very little, your vehicle should
be serviced at the regular time intervals
shown in the schedule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the
same mileage/time intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING CONDI-
TIONS
Additional maintenance items for severe
operating conditions; should be performed
on vehicles that are driven under especially
demanding conditions. Additional mainte-
nance items should be performed if you
primarily operate your vehicle under the
following conditions:
.
Repeated short trips of less than 5
miles (8 km).
.
Repeated short trips of less than 10
miles (16 km) with outside tempera-
tures remaining below freezing.
.
Operating in hot weather in stop-and-go
“rush hour” traffic.
.
Extensive idling and/or low speed driv-
ing for long distances, such as police,
taxi or door-to-door delivery use.
.
Driving in dusty conditions.
.
Driving on rough, muddy or salt spread
roads.
.
Using a car-top carrier.
NOTE:
For vehicles operated in Canada, both
standard and severe maintenance items
should be performed at every interval.
The following tables show the standard
maintenance schedule. Depending upon
weather and atmospheric conditions, vary-
ing road surfaces, individual driving habits
and vehicle usage, additional or more
frequent maintenance may be required.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the
same mileage/time intervals.

NOTE:
(1) After 40,000 miles (64,000 km) or 48
months, inspect every 10,000 miles
(16,000 km) or 12 months. Replace the
drive belts if found damaged.
(2) If operating mainly in dusty conditions,
more frequent maintenance may be re-
quired.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000
miles (168,000 km) or 84 months. After
first replacement, replace every 75,000
miles (120,000 km) or 60 months.
(5) Use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. Mixing any other type of coolant or
the use of non-distilled water may reduce
the life expectancy of the factory fill
coolant.
(6) Replace spark plug when the plug gap
exceeds 0.055 in (1.4 mm) even if within
specified replacement mileage.
(7) Periodic maintenance is not required.
However, if valve noise increases, inspect
valve clearance.
*: Maintenance items and intervals with
“*” are recommended by INFINITI for
reliable vehicle operation. The owner does
not need to perform such maintenance in
order to maintain the emission warranty or
manufacturer recall liability. Other main-
tenance items and intervals are required.

FUEL INFORMATION
Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number
96).
If unleaded premium gasoline is not avail-
able, unleaded regular gasoline with an
octane rating of at least 87 AKI number
(Research octane number 91) may be
temporarily used, but only under the
following precautions:
.
Have the fuel tank filled only partially
with unleaded regular gasoline, and fill
up with unleaded premium gasoline as
soon as possible.
.
Avoid full throttle driving and abrupt
acceleration.
Use unleaded premium gasoline for max-
imum vehicle performance.
CAUTION
.
Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
warranty coverage.
.
Under no circumstances should a leaded
gasoline be used, because this will
damage the three-way catalyst.
.
Do not use E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed to
run on E-15 or E-85 fuel. Using E-15 or E-
85 fuel in a vehicle not specifically
designed for E-15 or E-85 fuel can
adversely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the INFINITI new vehicle
limited warranty.
.
Do not use fuel that contains the octane
booster methylcyclopentadienyl manga-
nese tricarbonyl (MMT). Using fuel con-
taining MMT may adversely affect
vehicle performance and vehicle emis-
sions. Not all fuel dispensers are labeled
to indicate MMT content, so you may
have to consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of MMT
in reformulated gasoline.
.
U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter (WWFC)
specifications where it is available. Many
of the automobile manufacturers devel-
oped this specification to improve emis-
sion system and vehicle performance. Ask
your service station manager if the gaso-
line meets the World-Wide Fuel Charter
(WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing
reformulated gasolines. These gasolines
are specially designed to reduce vehicle
emissions. INFINITI supports efforts to-
wards cleaner air and suggests that you
use reformulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. INFINITI does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your INFINITI
cannot be readily determined. If in doubt,
ask your service station manager.
If you use oxygenate-blend gasoline,

Technical and consumer information
please take the following precautions as
the usage of such fuels may cause vehicle
performance problems and/or fuel system
damage.
.
The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
.
If an oxygenate-blend, excepting a
methanol blend, is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
.
E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and should
not be used. Damage caused by such
fuel is not covered by the INFINITI new
vehicle limited warranty.
.
If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in INFINITI
vehicles.
If any undesirable driveability problems
such as engine stalling or hard hot starting
are experienced after using oxygenate-
blend fuels, immediately change to a non-
oxygenate fuel or a fuel with a low blend of
MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.
E-15 fuel
E-15 fuel is a mixture of approximately
15% fuel ethanol and 85% unleaded
gasoline. E-15 can only be used in vehicles
designed to run on E-15 fuel. Do not use E-
15 in your vehicle. U.S. government reg-
ulations require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
E-85 fuel
E-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded
gasoline. E-85 can only be used in a
Flexible Fuel Vehicle (FFV). Do not use E-
85 fuel in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting
additive. INFINITI does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding 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 injector cleaner, octane booster, in-
take valve deposit removers, etc.) which
are sold commercially. Many of these
additives intended for gum, varnish or
deposit removal may contain active solvent
or similar ingredients that can be harmful
to the fuel system and engine.

Octane rating tips
Using unleaded gasoline with an octane
rating 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 recommended you have
an INFINITI retailer correct the condition.
Failure to correct the condition is misuse of
the vehicle, for which INFINITI is not
responsible.
Incorrect ignition timing will result in
knocking, after-run 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 vehicle checked. It is recommended
you visit an INFINITI retailer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating 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 RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see “Capacities and recommended fluids/
lubricants” (P.10-2). INFINITI recommends
the use of an energy conserving oil in order
to improve fuel economy.
Select only engine oils that meet the
American Petroleum Institute (API) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification mark
on the front of the container. Oils which do
not have the specified quality label should
not be used as they could cause engine
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.

Technical and consumer information
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 important that the engine oil viscosity
be selected based on the temperatures at
which the vehicle will be operated before
the next oil change. Choosing an oil
viscosity other than that recommended
could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, use the genuine oil filter or its
equivalent for the reason described in
change intervals.
Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Oil and
filter other than the specified quality, or oil
and filter change intervals longer than
recommended could reduce engine life.
Damage to engines caused by improper
maintenance or use of incorrect oil and
filter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warran-
ties.
Your engine was filled with a high quality
engine oil when it was built. You do not
have to change the oil before the first
recommended change interval.
AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
The air conditioning system in your
INFINITI vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN A/C system oil Type S
or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant
may cause severe damage to the air
conditioning system and may require the
replacement of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
governmental regulations require the re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.
It is recommended you visit an INFINITI
retailer when servicing your air condition-
ing system.
