2018 INFINITI QX30 check engine

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
Technical information10-5

For Canada:
If you believe that your vehicle has a defect
which could cause a crash or could cause
injury or death, you should immediately in-
form Transport Canada in addition to notify-
ing INFINITI.
If Transport Canada receives complaints, it
may open an investigation, and if it finds that
a safety defect exists in a group of vehicles, it
may request that INFINITI conduct a recall
campaign. However, Transport Canada can-
not become involved in individual problems
between you, your retailer, or INFINITI.
You may contact Transport Canada’s Defect
Investigations and Recalls Division toll free at
1-800-333- 0510. You may also report
safety defects online at:
https://wwwapps.tc.gc.ca/Saf-Sec- Sur/7/
PCDB-BDPP/Index.aspx.
Additional information concerning motor ve-
hicle safety may be obtained from Transport
Canada’s Road Safety Information Center at
1-800-333- 0371 or online at

or www.tc.gc.ca/securiteroutiere (French
speakers).
To notify INFINITI of any safety concerns
please contact our Consumer Information
Center toll free at 1-800- 361-4792.WARNING
A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dyna-
mometers used by some states for emis-
sions testing), or similar equipment. Make
sure you inform 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 trans-
mission damage or unexpected vehicle
movement which could result in serious ve-
hicle damage or personal injury.
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready con-
dition” for an Inspection/Maintenance (I/M)
test of the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving pat-
terns. Usually, the “ready condition” can be
obtained by ordinary usage of the vehicle.
If a powertrain system component is repaired
or the battery is disconnected, the vehicle
may be reset to a “not ready condition”. Be-
fore taking the I/M test, check the vehicle’s
inspection/maintenance test readiness con-
dition. Place the ignition switch in the ON
position without starting the engine. If the Malfunction Indicator Light (MIL) comes on
steady for 20 seconds and then blinks for 10
seconds, the I/M test condition is “not ready”.
If the MIL does not blink after 20 seconds,
the I/M test condition is “ready”.
It is recommended you contact an INFINITI
retailer to set the “ready condition” or to pre-
pare the vehicle for testing.
