2018 INFINITI QX30 check engine light

function and the low tire pressure warn-
ing light will flash for approximately 1
minute. The light will remain on after 1
minute. It is recommended you Contact
an INFINITI retailer as soon as possible
for tire replacement and/or system re-
setting.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•If you used Emergency Tire Sealant to
repair a minor tire puncture, the TPMS
sensor should be checked when repair-
ing or replacing the tire. It is recom-
mended you visit an INFINITI retailer for
this service.
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the
low tire pressure warning light is lit, and a tire
pressure-related warning (if equipped) ap-
pears in the vehicle information display, one
or more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light (in the meter panel). This system will
activate only when the vehicle is driven at
speeds above 16 MPH (25 km/h). For more details about the TPMS, see "Tire
Pressure Monitoring System (TPMS)" in the
"5. Starting and driving" section.

Parking brake*:
Check the parking brake operation regularly.
Also make sure that the vehicle is held se-
curely on a fairly steep hill when only the
parking brake is applied. If the parking brake
needs adjustment, it is recommended you
visit an INFINITI retailer for this service.
Seats:
Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches
lock securely in every position. Check that the
head restraints move up and down smoothly
and that the locks (if so equipped) hold se-
curely in all latched positions.
Seat belts:
Check that all parts of the seat belt system
(for example, buckles, anchors, adjusters and
retractors) operate properly and smoothly,
and are installed securely. Check the belt
webbing for cuts, fraying, wear or damage.
Steering wheel:
Check for changes in the steering condition,
such as excessive free play, hard steering or
strange noises.
Warning lights and chimes:
Make sure that all warning lights and chimes
are operating properly.Windshield defroster:
Check that the air comes out of the defroster
outlets properly and in good quantity when
operating the heater or air conditioner.
Windshield wiper and washer*:
Check that the wipers and washer operate
properly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*:
Except for maintenance free battery, check
the fluid level in each cell. It should be be-
tween the “UPPER” and “LOWER” lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of
the battery fluid level.
NOTE
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic
accessories that consume battery power
when the engine is not running (Phone
chargers, GPS, DVD players, etc.) 2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*:
Make sure that the brake fluid level is be-
tween the “MAX” and “MIN” lines on the res-
ervoir.
Coolant level*:
Check the coolant level when the engine is
cold.
Engine drive belt(s)*:
Make sure that no belt is frayed, worn,
cracked or oily.
Engine oil level*:
Check the level after parking the vehicle on a
level spot and turning off the engine. Wait
more than 15 minutes for the oil to drain back
into the oil pan.
Exhaust system:
Make sure there are no loose supports,
cracks or holes. If the sound of the exhaust
seems unusual or there is a smell of exhaust
fumes, immediately have the exhaust system
inspected. It is recommended you visit an
9-4Maintenance and Schedules

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
