2018 INFINITI QX30 ignition

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.

SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes. The disc-type brakes self-adjust ev-
ery time the brake pedal is applied.Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and fuse rating. The fuse ratings are
listed in the fuse allocation chart.
If the newly inserted fuse also blows, have
the cause traced and rectified. It is recom-
mended you visit an INFINITI retailer for this
service.
The fuses in your vehicle disconnect faulty
circuits. if a fuse blows, all the components on
the circuit and their functions will fail.

To ensure smooth, trouble-free, safe and
economical driving, INFINITI provides two
maintenance 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 sched-
ule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the same
mileage/time intervals.
OIL CHANGE MONITOR
This vehicle is equipped with oil change moni-
tor. It calculates engine oil and filter change
interval base on driving conditions. When the
Engine Oil – Service Due Now warning ap-
pears in the vehicle information display, the
engine oil and filter need to be replaced.
MAINTENANCE SERVICE
MESSAGES
The maintenance service interval display in-
forms you of the next service due date.
NOTE
The maintenance service interval display
does not show any information on the engine
oil level.
The vehicle information display shows a ser-
vice message for a few seconds, for example:
•[Service A In .. days]
•[Service A Due]
•[Service A Exceeded by .. days]
Depending on the operating conditions of the
vehicle, the remaining time or distance until
the next service due date is displayed.
The letter indicates which service is due. A
stands for a minor service and B for a major
service. A number or another letter may be
displayed after the letter.
Only for certain countries: the position after
the letter A or B indicates any necessary ad-
ditional maintenance work. If you notify an
INFINITI retailer of this display, you will re-
ceive a statement on the associated costs.
The maintenance service interval display does
not take into account any periods of time dur-
ing which the battery is disconnected.
Maintaining the time-dependent service
schedule:
Note down the service due date displayed in
the vehicle information display before dis-
connecting the battery.
or
After reconnecting the battery, subtract the
battery disconnection periods from the ser-
vice date shown on the display.

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 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.
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
based on the temperatures at which the vehicle
will be operated before the next oil change.
Choosing an oil viscosity other than that recom-
mended could cause serious engine damage.

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
vehicle safety may be obtained from Trans-
port Canada’s Road Safety Information
Center at 1-800-333- 0371 or online at

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 theMalfunction 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 sec-
onds, 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.
