engine INFINITI QX30 2018 Owner's Manual

Some day-to-day and regular maintenance is
essential to maintain your vehicle’s good me-
chanical condition, as well as its emission and
engine performance.
It is the owner’s responsibility to make sure
that the specified maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives the
proper maintenance care. You are a vital link
in the maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-
to-day operation of the vehicle. They are es-
sential if your vehicle is to continue to operate
properly. It is your responsibility to perform
these procedures regularly as prescribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks and inspections can be done by
yourself, a qualified technician, or if you pre-
fer, an INFINITI retailer.
SCHEDULED MAINTENANCE
The maintenance items listed under "Mainte-
nance schedules" later in this section are re-
quired to be serviced at regular intervals.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and serviced. It is recom-
mended you visit an INFINITI retailer for this
service.
INFINITI technicians are well-trained spe-
cialists and are kept up to date with the latest
service information through technical bulle-
tins, service tips and training programs. They
are completely qualified to work on INFINITI
vehiclesbeforework begins.
You can be confident that an INFINITI retail-
er’s service department can perform the ser-
vice needed to meet the maintenance re-
quirements on your vehicle.During normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section.
If you detect any unusual sounds, vibrations
or smells, be sure to check for the cause or
have an INFINITI retailer do it promptly. In
addition, it is recommended you notify an
INFINITI retailer if you think that repairs are
required.
When performing any checks or maintenance
work, closely observe "Explanation of general
maintenance items" later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with “*” is found later in the “Do-it-
yourself” section of this manual.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless other-
wise specified.
Doors and engine hood:
Check that all doors, the lift gate and the
engine hood operate smoothly. Also make
sure that all latches lock securely. Lubricate if
necessary. Make sure that the secondary
latch keeps the hood from opening when the

9-2Maintenance and Schedules

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.
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
INFINITI retailer for this service. See "Precau-
tions when starting and driving".
Fluid leaks:
Check under the vehicle for fuel, oil, water or
other fluid leaks after the vehicle has been
parked for a while. Water dripping from the
9-4Maintenance and Schedules

air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes
are evident, check for the cause and have it
corrected immediately.
Radiator and hoses:
Check the front of the radiator and clean off
any dirt, insects, leaves, etc., that may have
accumulated. Make sure the hoses have no
cracks, deformation, rot or loose connec-
tions.
Underbody:
The underbody is frequently exposed to cor-
rosive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust will
form on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information, see
"Cleaning exterior".
Windshield washer fluid*:
Check that there is adequate fluid in the res-
ervoir.The following descriptions are provided to
give you a better understanding of the sched-
uled maintenance items that should be regu-
larly checked or replaced. The maintenance
schedule indicates at which mileage/time in-
tervals each item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer to
"General maintenance" in this section.
Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You
are not required to perform maintenance on
these items in order to maintain the warran-
ties which come with your vehicle. Other
maintenance items and intervals are required.
When applicable, additional information can
be found in the “Do-it-yourself” section in
Chapter 8.
NOTE
INFINITI does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on an INFINITI product.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been vali-
dated by INFINITI.For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to "Recom-
mended fluids/lubricants and capacities".
EMISSION CONTROL SYSTEM

9-6Maintenance and Schedules

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.

Information about service
Resetting the maintenance service interval
display:
CAUTION
If the maintenance service interval display
has been inadvertently reset, this setting
can be corrected at an INFINITI retailer.
Have service work carried out as described
in the Maintenance Schedule. This may
otherwise lead to increased wear and dam-
age to the major assemblies or the vehicle.
An INFINITI retailer will reset the mainte-
nance service interval display after the service
work has been carried out. You can also ob-
tain further information on maintenance
work, for example.Special service requirements:
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions
or increased loads, for example:
•Regular city driving with frequent interme-
diate stops
•If the vehicle is primarily used to travel
short distance
•For frequent operation in mountainous
terrain or on poor road surfaces
•If the engine is often left idling for long
periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil
filter changed more frequently. The tires must
be checked more frequently if the vehicle is
operated under increased loads. Further in-
formation can be obtained at an INFINITI
retailer.
9-8Maintenance and Schedules

The following tables show the standard maintenance schedule. Depending upon weather and atmospheric conditions, varying 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.
