2018 INFINITI QX30 maintenance

For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to "Recom-
mended fluids/lubricants and capacities" in
the "10. Technical information" section.
EMISSION CONTROL SYSTEM
MAINTENANCE
Drive belts*:
Check engine drive belts for wear, fraying or
cracking and for proper tension. Replace any
damaged drive belts
Engine air filter*:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
check/replace the filter more frequently.
Engine coolant*:
Replace coolant at the specified interval.
When adding or replacing coolant, be sure to
use only Genuine INFINITI Engine Coolant or
equivalent in its quality (BASF Glysantin®
G40®). (For additional information, refer to

NOTE
Mixing any other type of coolant or the use
of non-distilled water may reduce the rec-
ommended service interval of the coolant.
Engine oil and oil filter:
Replace engine oil and oil filter at the speci-
fied intervals. For recommended oil grade
and viscosity refer to "Recommended fluids/
lubricants and capacities" in the "10. Techni-
cal information" section calinformationTech-
nical information" section information"
section.
Fuel filter:
Replace the fuel filter and drain the water at
the specified intervals.
Fuel lines*:
Check the fuel hoses, piping and connections
for leaks, looseness, or deterioration. Tighten
connections or replace parts as necessary.
Spark plugs:
Replace at specified intervals. Install new
plugs of the type as originally equipped.
CHASSIS AND BODY
MAINTENANCE
Brake lines and cables:
Visually inspect for proper installation. Check
for chafing, cracks, deterioration, and signs
of leaking. Replace any deteriorated or dam-
aged parts immediately.
Brake pads, rotors, drums, & linings:
Check for wear, deterioration and fluid leaks.
Replace any deteriorated or damaged parts
immediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deterioration,
and damage. Tighten connections or replace
parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions, re-
place the filter more frequently.
9-6Maintenance and Schedules

Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (4WD/AWD).
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots:
Check for damage, looseness, and leakage of
oil or grease. Under severe driving conditions,
inspect more frequently
Tire rotation:
Tires should be rotated every 5,000 miles
(8,000 km) according to the instructions un-
der "Tire rotation*" earlier in this section.
When rotating tires, check for damage and
uneven wear. Replace if necessary.
Transmission fluid/oil, differential oil,
transfer case oil:
Visually inspect for signs of leakage at speci-
fied intervals.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.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
SYSTEMS
Additional maintenance items for severe op-
erating conditions; should be performed on
vehicles that are driven under especially de-
manding conditions. Additional maintenance
items should be performed if you primarily
operate your vehicle under the following con-
ditions:
•Repeated short trips of less than 5 miles in
normal temperatures or less than 10 miles
in freezing temperatures.
•Stop-and-go traffic in hot weather or low
speed driving for long distances.
•Driving in dusty conditions or on rough,
muddy or salt-spread roads.
•Towing a trailer, or using a camper or car-
top carrier.
OIL CHANGE MONITOR
This vehicle is equipped with oil change moni-
tor. It calculates engine oil and filter change
interval base on driving conditions. Driving in
severe conditions will shorten the engine oil
and filter change interval. When the Engine
Oil – Service Due Now warning appears in
the vehicle information display, the engine oil
and filter need to be replaced.
NOTE
For vehicles operated in Canada, both stan-
dard and severe maintenance items should
be performed at every interval.
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.
MAINTENANCE SCHEDULES
Maintenance and Schedules9-7

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 during which the battery is discon-
nected. 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.
Hiding service messages
Press the orbutton on the steer-
ing wheel.
Displaying service messages
1. Switch the ignition on.
2. Press the
orbutton on the
steering wheel to select the [Serv.] menu.
3. Press the
orbutton to select
[Maintenance] submenu and confirm by
pressing the OK button.
The service due date appears in the vehicle
information 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
9-8Maintenance and Schedules

•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.
Maintenance and Schedules9-9

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.
