2018 INFINITI QX30 service

Many of the automobile manufacturers de-
veloped this specification to improve emis-
sion system and vehicle performance. Ask
your service station manager if the gasoline
meets the World-Wide Fuel Charter
(WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
INFINITI supports efforts towards cleaner air
and suggests that you use reformulated
gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
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, 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 recom-
mended for unleaded gasoline.
•If an oxygenate-blend, other than 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% oxygen-
ate. E-15 fuel will adversely affect the emis-
sion control devices and systems of the ve-
hicle 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 suit-
able amount of appropriate cosolvents and
corrosion inhibitors. If not properly formu-
lated with appropriate cosolvents and cor-
rosion inhibitors, such methanol blends may
cause fuel system damage and/or vehicle
performance problems.
At this time, sufficient data is not avail-
able to ensure that all methanol blends
are suitable for use in INFINITI vehicles.
If any driveability problems such as engine
stalling and difficult hot-starting are experi-
enced after using oxygenate-blend fuels, im-
mediately change to a nonoxygenate fuel or a
fuel with a low blend of MTBE.
Take care not to spill gasoline during refuel-
ing. 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 regulations require
fuel ethanol dispensing pumps to be identi-
fied with small, square, orange and black la-
bel with the common abbreviation or the ap-
propriate 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 Ve-
hicle (FFV). Do not use E-85 fuel in your
vehicle. U.S. government regulations require
fuel ethanol dispensing pumps to be identi-
fied by a small, square, orange and black label
with the common abbreviation or the appro-
priate percentage for that region.
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 af-
fect vehicle performance, including the emis-
sions 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.
10-4Technical information

Selecting the correct oil filter
Your new vehicle is equipped with a high—
quality genuine INFINITI oil filter. When re-
placing, it is recommended you use the genu-
ine 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. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals 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
New Vehicle Limited Warranty.
Your engine was filled with a high quality en-
gine oil when it was built. You do not have to
change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle.Operation under the following conditions may
require more frequent oil and filter changes:
•Repeated short distance driving at cold
outside temperatures
•Driving in dusty conditions
•Extensive idling
•Stop and go “rush hour” traffic
Refer to the “INFINITI Service and Mainte-
nance Guide” for the maintenance schedule.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system of your vehicle
must be charged with the refrigerant HFC-
134a and the lubricant INFINITI A/C System
Oil Type S or the exact equivalents.
CAUTION
The use of any other refrigerant or oil may
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFC-134a in your vehicle will
not harm the Earth’s ozone layer. However, it
may contribute in a small part to the global
warming effect.
Certain government regulations require the re-
covery and recycling of any refrigerant during
automotive air conditioner system service. An
INFINITI retailer has the trained technicians and
equipment needed to recover and recycle your
air conditioner system refrigerant.
It is recommended that you visit an INFINITI
retailer when servicing your air conditioner
system.
10-6Technical information

DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must con-
form to federal safety requirements in addi-
tion to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one and
one-half (1 1/2) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon ac-
tual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
TRACTION AA, A, B AND C
The traction grades, from highest to lowest,
are AA, A, B and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of as-
phalt and concrete. A tire marked C may have
poor traction performance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dissi-
pate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levels
of performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
build-up and possible tire failure.

10-16Technical information

This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems
performed. The EDR is designed to record
data related to vehicle dynamics and safety
systems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
•How various systems in your vehicle were
operating.
•Whether or not the driver and passenger
safety belts were buckled/fastened.
•How far (if at all) the driver was depressing
the accelerator and/or brake pedal.
•How fast the vehicle was traveling.
•Sounds are not recorded.
This data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.
NOTE: EDR data are recorded by your ve-
hicle only if a nontrivial crash situation occurs;
no data are recorded by the EDR under nor-
mal driving conditions and no personal data
(e.g. name, gender, age and crash location)
are recorded. However, other parties, such as
law enforcement, could combine the EDRdata with the type of personally identifying
data routinely acquired during a crash inves-
tigation.
To read data recorded by an EDR, special
equipment is required and access to the ve-
hicle or the EDR is needed. In addition to the
vehicle manufacturer and INFINITI retailer,
other parties, such as law enforcement, that
have the special equipment, can read the in-
formation if they have access to the vehicle or
the EDR. EDR data will only be accessed with
the consent of the vehicle owner or lessee or
as otherwise required or permitted by law.Genuine INFINITI Service Manuals for this
model year and prior can be purchased. A
Genuine INFINITI Service Manual is the best
source of service and repair information for
your vehicle. This manual is the same one
used by the factory trained technicians work-
ing at INFINITI retailers. Genuine INFINITI
